    Carbon Steel Pipe Welding

    Welding problems are sometimes encountered during the installation of carbon steel pipes . So, how to weld pipes? What should be paid attention to when welding carbon steel pipe? Carbon steel pipe welding is mostly done through MIG welding. Stick welding, TIG welding, and MIG welding processes are all used in carbon steel welding. A MIG welder is the best equipment to carry out flawless carbon steel welding, though, because the wire stiffness is designed to pass through the liner from the machine with minimum friction. Depending on the voltage of the MIG welder, the weld can include one of three transfer types—short circuit, spray, or globular transfer. Steel consists of iron and carbon with small amounts of miscellaneous metals, such as manganese, chromium, silicon, vanadium, and nickel. Low carbon steel contains only 0.3 percent carbon, making it incredibly easy to weld. Medium carbon contains 0.30 to 0.60 percent carbon, and high carbon steels at 0.61 to 2.1 percent carbon. By comparison, cast iron contains up to 3 percent carbon, which makes it incredibly challenging to weld. Carbon steel pipe welding precautions: 1. Before the pipeline is welded, it is necessary to remove all the debris in the pipe. After the construction is completed, a blocking plate can be used to seal it to prevent the debris from falling into it. At the same time, before welding, it is necessary to polish the oil stains on the nozzle part until the metal-like luster appears. 2. Generally speaking, the pipe material is basically spiral seam steel pipe , so the welding method of manual arc can be selected. For this kind of pipe, all welds need to be bottomed by argon arc welding, and the cover needs to be Fill with manual arc welding.

    Classification and Use of Carbon Steel

    Mild steel is a type of carbon steel. Carbon is present in all steels, and as long as carbon is the predominant alloying element in this steel, the alloy is considered carbon steel. "Low carbon" steel is another name for low carbon steel, and there are other carbon steels with different carbon contents. Which one is better depends on the purpose of the steel. How are carbon steel materials classified? The following is the introduction of carbon steel pipe manufacturers . More than 1.5 billion tons of steel are produced each year, which are used to make a variety of products, such as sewing needles and structural beams for skyscrapers. Carbon steel is the most commonly used alloy steel, accounting for about 85% of all U.S. production. The carbon content of the product is in the 0-2% range, and these alloys also contain small amounts of manganese, silicon and copper. Carbon steel can be classified according to the chemical composition and characteristics of the product, and can be divided into four categories: 1. Low carbon steel Mild steel has a carbon content of 0.04-0.3% and is the most common grade of carbon steel. Mild steel is also considered mild steel as it is defined as having a low carbon content of 0.05-0.25%. Mild steel is ductile, highly malleable and can be used in automotive body parts, sheet and wire products. At the high end of the low carbon content range, plus up to 1.5% manganese, the mechanical properties are suitable for stampings, forgings, seamless tubes and boiler plates. 2. Medium carbon steel Medium carbon steels have a carbon content in the range of 0.31-0.6% and a manganese content in the range of 0.6-1.65%. This steel can be heat treated and quenched to further tune the microstructure and mechanical properties. Popular applications include axles, axles, gears, rails and railroad wheels. 3. High carbon steel High carbon steel has a carbon content of 0.6-1% and a manganese content of 0.3-0.9%. The properties of high carbon steel make it suitable for use as springs and high strength wire. These products cannot be welded unless a detailed heat treatment procedure is included in the welding procedure. High carbon steel is used for cutting tools, high strength wire and springs. 4. Ultra-high carbon steel Ultra-high carbon steels have a carbon content of 1.25-2% and are known as experimental alloys. Tempering produces very hard steel, which is useful for applications such as knives, axles or punches.

    What is Carbon Steel Pipe Used for?

    Carbon steel pipe is an extremely durable material used in heavy-duty industries such as infrastructure, shipping and fertilizers. The higher carbon content gives the steel a lower melting point, making it more ductile and durable, and better able to dissipate heat. It is often used as a pipeline for steam, coal gas, liquefied gas, natural gas, various petroleum products and various other gases or liquids. Usage of carbon steel pipe: 1. Pipes for machinery industry. Such as aviation structural pipes (round pipes, elliptical pipes, flat elliptical pipes), automobile semi-axle pipes, axle pipes, automobile tractor structural pipes, tractor oil cooler pipes, agricultural machinery square pipes and rectangular pipes, transformer pipes and bearings tube etc. 2. Pipes for petroleum geological drilling. Such as: oil drilling pipe, oil drill pipe (kelly and hexagonal drill pipe), drill pipe, oil tubing, oil casing and various pipe joints, geological drilling pipe (core pipe, casing, active drill pipe, drill pipe) , press hoop and pin joints, etc.). 3. Pipes for chemical industry. Such as: oil cracking pipes, chemical equipment heat exchangers and pipes, stainless acid-resistant pipes, high-pressure pipes for fertilizers, and pipes for transporting chemical media, etc. 4. Pipes for pipes. Such as: seamless pipes for water, gas pipes, steam pipes, oil pipelines, and pipes for oil and natural gas trunk lines. Agricultural irrigation faucets with pipes and sprinkler irrigation pipes, etc. 5. Tubes for thermal equipment. Such as boiling water pipes, superheated steam pipes for general boilers, superheating pipes, large smoke pipes, small smoke pipes, arch brick pipes and high temperature and high pressure boiler pipes for locomotive boilers. 6. Other departments use pipes. Such as: tubes for containers (tubes for high-pressure gas cylinders and tubes for general containers), tubes for instrumentation, tubes for watch cases, injection needles and tubes for medical devices, etc.

    What is Carbon Steel Pipe?

    Carbon steel is an alloy steel containing iron and carbon. Carbon steel pipe is an extremely durable material used in heavy-duty industries such as infrastructure, shipping and fertilizers. The higher carbon content gives the steel a lower melting point, making it more ductile and durable, and better able to dissipate heat. Classification of carbon steel pipes: Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (pulled) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, non- Rust thin-walled steel pipe, special-shaped steel pipe. The outer diameter of hot-rolled seamless pipes is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless pipes can reach 6mm and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipes can reach 5mm and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling. General carbon steel pipe: It is made of 10, 20, 30, 35, 45 and other high-quality carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold-rolled. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transportation pipelines. 45, 40Cr and other medium carbon steel seamless pipes are used to manufacture mechanical parts, such as the stressed parts of automobiles and tractors. Generally, carbon steel pipes are used to ensure the strength and flattening test. Hot-rolled steel pipes are delivered in a hot-rolled state or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state. Carbon steel carbon content % Ultra High Carbon Steel 1.00 – 2.00 High carbon steel 0.60 – 0.99 Carbon Steel 0.30 – 0.59 Mild Steel 0.16 – 0.29 Ultra low carbon steel 0.05 – 0.15 Advantages of carbon steel pipe: Due to the durability and shock resistance of carbon steel, pipes made from this material are not affected by environmental conditions such as pressure or extreme weather. This makes it an ideal material for structural piping applications, such as those laid under roads. Pipes can be made thinner while still carrying large volumes of corrosive materials. Carbon steel pipes are also safe for the environment, as approximately 50% of the world's steel is made from recycled materials.
