Black steel is a type of steel that plays an important role in many projects as well as applications related to life. So what is black steel pipe and its advantages to make it is used in so many projects like that, today let's learn about black steel pipe with MRS Steel with the most detail in the article below!1. Definition about black steel pie and the important specificationsBlack steel pipe is a product created on the hot rolling process of black steel sheet material, it can be said that this pipe is a form of steel that has not been galvanized. Instead of going through a galvanizing process like many other steels, this steel just undergoes a chemical conversion to create a black or magnetic iron oxide layer. Therefore, the surface this steel is often dark blue and rough based on the dark iron oxide shell on its surface.Black steel pipe is produced based on certain standards and parameters, usually there are 2 standards most commonly applied today to evaluate black steel pipes including ASTM A53 and ASTM A106.Accordingly, the ASTM A53 standard will include the required metal components such as Carbon, Manganese, Phosphorus, Nickel, Chromium, Molybdenum and Vanadium in small proportions, the composition is mainly Iron. In which the sum of 5 elements Copper, Chromium, Molybdenum, Nickel and Vanadium must be less than 1%.ElementsPercentagesCMax 0.3%MnMax 1.2%PMax 0.5%SMax 0.045% ASTM A106 standard is a seamless black steel pipe, meaning that they will not have the joints as basic steel pipe and they are commonly used in high temperature environments. The composition of ASTM A106 type will be similar to that of standard A53, there are only minor differences as the total composition of this standard is now supplemented with Silicon.ElementsPercentagesCMax 0.35MnMax 1.06PMax 0.35SMax 0.0352. History of formation and manufacturing processes of black steel pipeMethods of producing pipe steel appeared as early as more than 200 years ago and they have been gradually researched and developed to this day. The origin of steel pipes appeared in the 1800s when a British inventor created a system of coal-fired lamps to light up the street, from which the need to use steel pipes has paid attention day by day.In the early stages in the 1820s, researchers at that time created metal pipes by using fire to soften the metal sheet and proceed to join the metal edges and weld them together with a hammer. However, this method was replaced by a more advanced method and it is considered the premise for today's method of forming steel pipes. Basically, the metal sheets will be heated until a certain ductility is reached, then the manufacturer will pull them through a conical groove. As the metal passes through the groove, the edges of the metal will gradually roll and contract to form a long, round tubular shape.2.1. Manufacturing processes of welded steel pipeNowadays, the production methods of black steel pipe have been gradually automated by equipment, so the completion time is greatly accelerated while ensuring the technical uniformity. Black steel pipe is divided into 2 common types, namely welded steel pipe and seamless pipe steel, specifically, the production process of welded pipe steel takes place as follows:Slitting line stage: The manufacturer will put hot rolled steel coils into the slitting machine to cut the steel sheets into small widths.Rolling: Then the slitting steel will be moved through the clusters and cages to flatten and chamfer on both sides, making the steel surface uniform in size.Shaping: Next is the shaping stage, the steel strip then goes through a series of grooved rollers arranged parallel to both sides, as the steel moves towards the end, their shape will gradually be rolled to form a cylindrical shape.Welding black steel pipes: This is the step that requires the most technical machines because the joint line will greatly determine the durability of the black steel pipe in the future. The steel pipe will pass through a roller arranged above to create extremely strong friction on the groove. At the same time, both the inside and outside of the pipe are also sprayed with hot zinc to avoid the risk of rusting the joints.Quality check: Once the steel pipes have been successfully shaped, they will now go through the cutting machines to complete the final stage. Black steel pipes go through modern gauges to compare technical information as required to ensure the stability and quality of the finished product before being put on the market.2.2. Manufacturing processes of seamless steel pipeIn contrast to welded steel pipe, seamless steel pipe is derived from a billet, which is then heated and cast to form a hollow section steel. Seamless steel pipe production processes began to appear in the late 19th century and it gradually replaced welded steel pipe because the manufacturing process usually took place quickly in a relatively short period of time. Therefore, during World War II, seamless black steel pipes completely took advantage of applying in life and making weaponry at that time.Currently, manufacturers usually apply one of two main manufacturing processes to create seamless steel pipe including the Mandrel Mill process and the Mannesmann Plug Mill process. Both processes serve different purposes as Mandrel Mill is used to produce small diameter steel tubes from 25 - 150mm. Whereas the Mannesmann Plug Mill process produces seamless steel tubes with large diameters from 150 to 400 mm.Mandrel Mill processThe process begins with a billet bar heated to 1300 degrees Celsius and then the manufacturer will use a long piercing to drill into the top of the billet bar to create a small hole and this gap is the starting point for radius expansion taking place afterwards. The piercing tool will rotate continuously into the center of the steel pipe and this rotation speed is enough to cause the steel core to gradually melt through its path.After the steel pipe is successfully penetrated, it will move to the mandrel mill installed on the pipe. The series of rolls here are arranged in the direction of 90 degrees to continuously roll the surface of the steel pipe to reduce the outside diameter and control the thickness. When leaving the furnace and meeting the standard outside diameter, the steel pipe will now undergo a cleaning step with high-pressure water descale to remove excess oxide deposits formed during heating. They are finally moved to the cutoff mechanism to be cut to the prescribed length, then they will be bundled and checked again before implementing shipment.Mannesmann plug mill processThe process begins with a billet that has just been heated from the furnace and then the manufacturer will use a Mannesmann drill with the head is designed in a conical shape and the size is almost equal to the diameter of the pipe. This drill will rotate continuously into the center of the steel pipe diameter to create a large enough hollow.During the steel hollow drilling process, on the production line, two rollers will be installed in the opposite direction of the steel to reduce the steel diameter thickness. In order to ensure the quality of the hollow inside, the manufacturer will use a cylindrical mandrel with a size close to the hollow diameter inside it to rotate, the purposing of this stage is control the roundness inside the pipe. Then, the steel pipe is put into the decontaminating stage and be cutted to the required length, finally the product will go through heat treatment and cooling.3. The characteristics and role of black steel pipe in the current contextA great advantage that black steel pipe brings to the project is its affordable price. Thanks to the quick and simple production process without too much technical technology, the market price of black steel pipe is always reasonable, the level price is always in the low range. Cheap input materials will help managers be more proactive in investing in other areas of the project, thereby helping the plan become stable and reduce the risk of capital shortage. Although the price is cheap, this does not affect the quality of the steel, specifically the black steel pipes have high homogeneity thanks to the production process on the same line, so the durability as well as the mechanical properties are not compromised and they obtain consistency from beginning stage to the end stage. In addition, black steel pipe will not shrink when exposed to high temperatures, the nature of black pipe steel is formed from billet with a temperature of up to 1500 degrees Celsius, so it can keep the original shape even after being heated.However, the black steel pipe is considered for environmental problems in its production process because the production requires the factory to burn fossil fuels and this leads to the large amount of smoke emitted into the atmosphere, polluting water and soil. In terms of long-term economic impacts, this steel pipe is still an ideal choice as the steel's durability has kept it existing for decades, this steel pipe is possible to become an optimal economical solution for the facility infrastructure as well as other manufacturing applications.Green steel production projects have been gradually popularized to many places of the world, green steel technology completely eliminates the use of fossil fuels from the process, helping the mills cut down on up to 90% the amount of carbon emissions. The importance of scrap steel is also being concerned by many manufacturers when it helps businesses save energy resources and be more proactive in finding input raw materials without having to invest in eloring natural mining sites.4. Applications of black steel pipe in the fieldsPossessing a variety of diameters from 12x12 mm to 100x100 mm and even up to 250x250mm, black steel pipe is now an important factor in the construction field and many industries.4.1. Pipeline systemOne of the most common applications of pipe steel is taking advantage of making water, vapor and natural gas pipelines. Black steel pipe possesses good bearing capacity without distorting, so it will be suitable as a conduit at high pressure places. In addition, these pipes also appear in oil and gas pipelines because they are manufactured according to standard specifications so they can adapt well to corrosion and high temperature environments. Various lengths and sizes of steel pipes have made it easier for businesses to install at the locations, specifically in the installation of water and gas pipelines in urban and rural areas. Moreover, black steel pipes usually require less frequent maintenance, so they can be installed underground, which helps to increase the urban beauty with less obstruction to the surrounding ground.4.2. Building structureIn construction, black steel pipe is used as the foundation of the building as well as appearing in load-bearing scaffolding. Steel pipe has a chemical composition including chromium, silicon to increase the strength and toughness of steel pipes, so it has the function of balancing and distributing the load evenly for the foundation with the scaffolding.Black steel pipe also appears in the ultrasonic pile system in the foundation structure of the building and it is the main raw material of pre-engineered steel buildings, the light weight of this pipe will help the construction process become more convenient and easier.5. The difference between black steel pipe compared to other steelsBesides black steel pipe, there are many other types of steel pipe that are the same size and shape as black  pipe, moreover, they are very popular in construction and industrial applications. Some typical steel pipe products placed on the balance sheet compared with black steel pipes can be mentioned as carbon steel pipes and galvanized steel pipes.5.1 Black steel pipe and carbon steel pipeBlack steel pipe and carbon steel pipe basically still have the basic thing in common, which is an iron alloy with added carbon to create strength. Both types have the similar advantage of being extremely sturdy and durable, so they are very popularly used in the fields of construction and manufacturing engineering. However, if you examine closely each type of steel, you will see that they have significant differences.Structural compositionIn terms of composition, the amount of carbon in steel is also divided into different abundance levels from 0.05% to 2%. Meanwhile, black steel pipe has regulations on the amount of carbon content not exceeding 0.35%. Although the black pipe has a much smaller amount of carbon, they contain elements that carbon steel pipe does not possess such as chromium, silicon and manganese, which are extremely valuable in resisting corrosion and maintaining durability for steel.Carbon steels are composed mainly of iron and carbon, they have the least chromium content compared to other steels. The element chromium gives effective corrosion resistance to steel, so the absence of chromium will make the steel very susceptible to oxidation and rust surfaces.Strength and enduranceEvaluation of strength criteria, black steel pipe is more durable and harder than carbon steel pipe because the black iron oxide coating helps increase the hardness of the material, has the effect of protecting the surface of the steel pipe and effectively resisting corrosion. Meanwhile, because carbon steel pipe does not have additional anti-corrosion elements, its durability will be worse than black pipe steel, even when the atmospheric humidity increases to 70%, it can also cause carbon steel to oxidize.Black steel pipes on the market today are not usually required to be galvanized because they are equipped with a protective layer against corrosion that is formed through the manufacturing process, while carbon steel will require the manufacturer to proceed galvanizing steps to ensure they do not corrode. Especially in gas transportation or plumbing applications, carbon steel is not an appropriate choice.Eco-friendly in manufacturingThe use of black pipes for construction and industrial applications is considered more eco-friendly than carbon steel pipes. The reason is that the emissions from the production of carbon steel pipes are more than the leaking smoke in the production of black steel pipe. The reason why is that the carbon component accounts for the largest proportion of carbon steel pipe while black steel pipe may not need or will exist very little carbon components. Therefore, many people predict that in the future, it is likely that this black steel will gradually replace carbon steel in many fields before the trend of green economic development globally.5.2 Black steel pipe and galvanized steel pipeBlack steel pipe and galvanized steel pipe are the two most widely used steels in the transportation of oil, gas, water and other liquids. Both are tubular steels and have the same application, but if you put them on the scale, you will see that these two steels are significantly different.Corrosion resistanceAlthough black steel pipe coated with iron oxide has a significant effect on oxidation resistance, this steel is not superior to galvanized steel pipe. Galvanized pipes are coated with a layer of zinc and zinc is one of the leading elements for effective anti-corrosion, in addition, the zinc layer also helps prevent steel from being scratched and helps the steel surface to be maintained in the best condition.Pipeline system applicationsThe thicker the zinc layer, the longer the life of the steel, but some studies on air pipeline systems have shown that this zinc coating can peel off and clog pipes, leading to damage for pipe. Therefore, although galvanized steel pipe is very popular in liquid transmission systems, it is not suitable for gas transmission systems.In contrast, black steel pipe is proven to be a good air transportation product as well as used for fire protection systems because black steel pipe can withstand higher temperatures than galvanized steel pipe. However, black steel pipe is not a good choice for use as a pipeline for compounds with high concentrations of corrosive because this compound will dissolve into black steel pipe and cause pipeline blockage.Production cost and priceBlack steel pipe and galvanized steel pipe have a clear difference in cost because in the production process, manufacturers have to perform additional galvanizing steps for steel, so the cost to sell to the market will be higher than that of black steel pipe. In addition, during time for implementing the construction or commercial buildings, galvanized steel pipes will never be connected to black steel pipes.6.

Galvanized steel, thanks to its resistance to rust, corrosion and outstanding durability, has become an ideal material for many industrial fields.Have you fully understood the characteristics, pros and cons of galvanized steel and how the galvanizing process takes place? MRS Steel will get deeper into this material.Galvanized steel products are widely used in various industries due to their durability and corrosion resistanceWhat is galvanized steelGalvanized steel is a material that is coated with an outer layer of zinc to protect the product from the effects of the surrounding environment such as temperature, humidity, air,... Thereby, limiting the possibility of rust , anti-oxidation and corrosion to increase strength and life span of coils.Methods of galvanizing steelCurrently, there are 3 most commonly used galvanizing methods: cold galvanizing, hot -dipping galvanizing and electro galvanizing.Cold galvanizing methodCold galvanizing is a method of coating a layer of liquid zinc on the surface of the product at room temperature and then putting it through a cold galvanizing process. Here, the mill uses compressed air to blow a liquid solution to form a beam of zinc particles that shoots onto the metal surface. In the solution, there are additives to help the coating adhere firmly to the metal surface and harden in a short time. Cold galvanizing technology helps to improve the corrosion resistance of metal, so it is the best solution for galvanizing metal materials on site.The galvanized steel melting point typically ranges from 1420°C to 1460°C, depending on the specific composition of the alloyHot-dip galvanizing methodHot-dip galvanizing is the most popular coating technology today, capable of effectively protecting coils from the effects of the environment. This process starts from dipping the product into a molten solution to form a strong, non-flaking base and a smooth, highly aesthetic product surface.Electrolytic galvanizing methodElectrolytic galvanizing is a method of electrocoating that forms a thin layer of metal on the surface of a coil for the purpose of preventing metal corrosion, increasing electrical conductivity, size and hardness. In fact, the electrolytic galvanizing method is used for steel products such as water pipes, railways, outdoor equipment, bearing equipment, machine parts,...Learn about standard galvanizing processThere are 3 methods of galvanizing steel, but hot-dip galvanizing is still the most commonly used method in Vietnamese factories with the following standard implementation process:Step 1: Metal surface treatmentSteel made from iron ore or recycled steel also contains many impurities, dirt and oil that reduce the ability to adhere to the coating layer. Therefore, the material needs to be soaked in the degreasing solution for 10 - 15 minutes and transferred to a solution of hydrogen chloride concentration of 8 - 15% to remove rust.The density of galvanized steel varies depending on its composition and coating thicknessStep 2: Embed Soldering fluxAfter the steel is cleaned, it is dipped into the flux for about 3 - 20 seconds at normal temperature to completely remove the oxide and iron ions on the surface of the product. This is also the step that creates a coating that protects the steel from oxidation.Step 3: Hot dipped galvanizedSteel will be completely immersed in the galvanizing bath at the melting temperature (454 - 465 degrees Celsius) to create a layer of zinc coating on the surface. After completing the hot dipping process, performing slag scraping on the surface combined with vibration to remove excess zinc, the product will be coated with a layer of chromate to protect the surface comprehensively.Step 4: Cool down and check qualityIn order for the surface of the galvanized steel to be bright and beautiful, the product is cooled by an overflow bath. Experts observe and calculate the thickness of the coating by using specialized gauges to ensure that the finished product meets the specifications and requirements of the customer.Top reasons why you must galvanized steelLow costThe production cost of galvanized steel is much lower than other surface protection coating methods, so it is the first choice for large-scale construction projects.DurableThe zinc coating protects the coil from rust, environmental corrosion and chemical reactions of the inner steel components. According to research, GI has high durability, using life up to 50 years in ideal conditions and from 20-25 years in harsh conditions such as industrial zones, coastal areas, etc.AestheticsCompared with conventional steel products, galvanized steel has a shiny, smooth surface and is easily coated with high-grade color paint to increase aesthetics.Reduce maintenance costsGalvanized steel products have high durability, long service life, so it does not cost a lot of maintenance and regular maintenance during use.The "galvanized steel meaning" encompasses the process of coating steel with a protective zinc layer to enhance its corrosion resistanceApplication of galvanized steelGalvanized steel possesses high durability, good bearing capacity and is a familiar material in common applications such as deck floors, ventilation pipes, oil pipes, purlins, vehicle parts, household appliances, furniture,... In particular, galvanized steel is an ideal material for many important industries, specifically:Wind and solar industryThe solar energy projects need to operate continuously, so maintenance must be minimized to avoid disruptions and decrease in productivity. Additionally, due to exposure to harsh environmental conditions such as sun, wind, rain,..., the project is susceptible to deterioration and damage.Therefore, galvanized steel is widely popular in the wind and solar energy industries because of its durability, corrosion resistance and resistance to environmental factors, enduring for decades.Automobile industryGalvanized steel is an ideal material for manufacturing automobile frames and parts. Currently, about 80% of car bodies are made from galvanized steel with durability, rust resistance and many other advantages.Construction industryDurability is the top criterion in choosing construction materials. resident or commercial projects demand materials capable of bearing heavy loads, with high longevity, and minimal need for frequent maintenance. Therefore, large structural parts in buildings are often made of galvanized steel to ensure safety and sustainability.Telecommunications industryPhone lines are often in high, difficult-to-access positions, leading to irregular maintenance. Therefore, when choosing materials in the telecommunications industry, attention must be paid to sustainability and minimal maintenance requirements.The "galvanized steel meaning" encompasses the process of coating steel with a protective zinc layer to enhance its corrosion resistanceMRS Steel: providing the benefit of importing Vietnamese galvanized steelWith investment in infrastructure, modern equipment and strictly selected raw materials, Vietnam galvanized steel mills provide product lines with thicknesses from 1.5 to 3.0mm, coating degree Z275 - Z350, strength up to G450.FDI projects especially favor these types of galvanized steel because of their durability. high quality and good resistance to environmental conditions, so the life of the works can be up to 50 years.In addition, galvanized steel also meets many international standards such as JIS G3302 of Japan, BS EN 10346 of Europe, AS 1397, ASTM A792 of the United States, conquering many difficult export markets such as the EU. , the United States, Korea and Southeast Asia,...

Does galvanized steel need painting? Many people wonder if the nature of this material has antioxidant properties; will the paint add any more effects? To help you get the most accurate answer, below MRS Steel will summarize information related to this content.1. What is galvanized steel and its characteristics? Galvanized steel is a steel material covered with an outer layer of zinc to help it avoid the effects of the surrounding environment. Thereby limiting the possibility of rust, oxidation, and corrosion and increasing the durability and life of the product. Here are the salient features of galvanized steel:Zinc surfaces have the ability to slow down the oxidation of steel, helping to protect the surface from corrosion and avoiding rust in the long run.Under normal conditions, the service life of galvanized steel can be more than 60 years.With its ability to adapt to many different weather conditions, even sea salt and acids, this material is always a considered choice when it is necessary to use it in harsh environments.Thanks to these advantages, galvanized steel is widely used in construction projects, making roof frames, gates, doors,... In the electrical industry, heavy industry, chemical industry, and shipbuilding industry. In addition, the material is also used in household appliances, making power cable systems,...2. Can galvanized steel be painted?Galvanized steel is one of the most commonly used materials today. This steel itself is a product with high corrosion resistance, but it is aesthetically poor because there is only one color. Therefore, many people choose to paint colors on galvanized steel to increase the aesthetics as well as the corrosion resistance of the product.Galvanized steel is usually painted with an electrostatic powder coating or anti-rust paint. However, in order to paint, you need to go through many different processes, because if you leave the product as it was at first and then paint it, it will be extremely laborious, expensive, and easy to peel off the paint layer. The followingare the necessary steps to proceed with painting galvanized steel:Surface treatment before painting: Galvanized steel before painting needs to be surface treated for better adhesion. There are four methods of pre-treatment of steel surfaces before painting: rinsing, primer etching, blasting, and weathering.Choose the right paint: Paints used before painting steel surfaces are specially formulated and applied according to the manufacturer's recommendations.Work progresses: Coating the zinc surface must be done according to the manufacturer's instructions.3. How to choose galvanized paint?Currently, the paint used to paint galvanized steel is divided into two main types: single-component paint and two-component paint. Each type of paint has its own advantages and disadvantages, suitable for each use: 1-component galvanized paint: Suitable for civil works, it needs to be constructed quickly because this paint does not need to be mixed but can be used immediately. The price is also lower than that of two-component paint. However, it is not suitable for outdoor work or harsh weather conditions due to its low protection.2-component galvanized paint: This is the ideal paint for projects that need high durability and good resistance because this is a high-class epoxy paint system with two components mixed in proportion. Therefore, the cost of this paint group is also higher.MRS Steel has helped you answer the question of whether to paint on galvanized steel or not.

What is galvanized steel pipe used for? Let's explore these applications in agriculture, solar energy, oil industry, construction and more with MRS Steel!Galvanized steel pipe has been coated with zinc to protect the steel from corrosion. GI is most commonly used for outdoor construction such as fencing, handrails and interior plumbing applications (plumbing, fire fighting systems,…). MRS Steel will dive deeper into the issue of “what is galvanized steel pipe used for”.What is galvanized steel pipe used for? Explore now with MRS SteelWhat is galvanized steel pipeGalvanized steel pipes are hollow, thin-walled steel structures with good load-bearing capacity and minimal impact from environmental factors. The addition of an external zinc coating further enhances their resistance to rust formation, oxidation and environmental influences such as climate, temperature, humidity,...Galvanized steel is divided into hot-dip galvanizing and electroplating with different characteristics and pros and cons:Hot dipped galvanized steel pipeHot-dip galvanizing is the traditional method of coating steel pipes with a protective layer. Surface-treated steel pipes are dipped into a tank of molten zinc. The zinc layer is evenly coated on both sides, with good rust resistance, adhesion and long life expectancy. GI's zinc coating is usually about 50 micrometers thick on average.Electrolytic galvanized steel pipeElectrolytic galvanizing, also known as cold galvanizing, only uses a very small amount of zinc, about 10-50g/m2 to coat the outer surface of various products. Electrolytic plating technology creates a precipitate on the metal layer, so the corrosion resistance is much worse than that of hot-dip galvanized steel. Products cold-plated have low cost, high adhesion, and low deformation at high temperatures.Galvanized steel pipes offer strength, rust resistance and versatility for construction needsGalvanized steel pipe classificationRound steel pipes: mainly used for water pipes, lamp posts, railings, stair handrails, ultrasonic piles,...Square and rectangular steel pipe: depending on the thickness of the steel pipe, it will be used as a roof frame, scaffolding or in the manufacture of furniture, motor vehicle parts, ...Oval steel pipe: this type of galvanized steel pipe is widely used in the field of furniture, frames’s car, motorcycles, bicycles,...What is galvanized steel pipe used for?Galvanized steel pipes have many outstanding features such as high aesthetics, comprehensive protection, good life expectancy, ... when applied to projects and fields of life.Applications in solar energySolar panels have a large mass of 20-24kg to ensure that the system is not affected by the effects of storms or high winds. Therefore, the support frame needs to be strong, capable of withstanding large loads and wind levels of 10, level 12 in stormy weather. In addition, the frames that support the solar system are placed outside and are often affected by the weather, so they must resist corrosion.In almost all materials, galvanized steel can meet all of the above requirements thanks to its stable, solid, high-strength, load-bearing and good-bearing structure. The zinc coating on the outside of the steel pipes has a comprehensive protection effect, increasing the long term use of the frame system. Therefore, galvanized steel, especially pipe steel, box steel, V-shaped steel,..., are often chosen as frames for solar power systems.Galvanized steel ensures durable and corrosion-resistant frames for solar power systemsApplication in agricultureGalvanized steel pipe has good rust resistance, variety of sizes, easy to shape and install, so it is widely used in irrigation systems.Black steel pipes, hot-dip galvanized steel pipes are also widely used in animal husbandry.
