The knowledge of carbon steel seamless pipe,how much do you know?

Nov. 08, 2019

Our company is one of the professional carbon steel seamless pipe manufacturer in our country. We have many kinds of carbon steel seamless pipe, for example, carbon steel seamless gas pipe. Win unanimous praise from people inside and outside the industry. Now allow me to introduce you to the relevant knowledge of these products.

Carbon steel seamless pipes are widely used. Seamless steel pipes for general use are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with large output, and are mainly used as pipes or structural parts for conveying fluids. Supply is divided into three types according to different purposes: A. supply according to chemical composition and machinery performance; B. according to the mechanical performance supply; C. according to the water pressure test supply. Steel pipes supplied according to categories A and B, if used to withstand liquid pressure, shall also be subjected to hydraulic pressure test. 3. Special purpose seamless pipes. There are many kinds of seamless pipes for boilers, chemical power, geological seamless steel pipes and petroleum seamless pipes. Seamless steel pipes have a hollow cross section and are widely used as Conduit for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water and certain solid materials.  Compared with solid steel such as round steel, steel pipe is lighter in weight when its bending and torsion strength is the same, and it is an economic section steel. It is widely used to manufacture Structure parts and machinery parts, such as petroleum drill pipes, auto transmission shafts (consisting of shaft pipes, telescopic sleeves and universal joints), bicycle frames and steel scaffolds used in construction.

Black Carbon Welded Steel Pipe

Circular parts made of steel pipes can improve the availability of materials, simplify the manufacturing process, save materials and working hours. Steel pipes have been widely used for manufacturing. Carbon steel seamless gas pipes are mainly used to transport oil and gas in the world. There are roughly three types of pipes: submerged arc welding pipes include straight submerged arc welding pipes and spiral submerged arc welding pipes. High frequency straight seam welded pipe and seamless steel pipe.  The same is true in China, where LSAW, SSAW, ERW and SMLS are the main types of steel pipes.  First of all, it is necessary to explain that the main technical requirements of oil and natural gas transmission steel pipes for pipeline technology are mainly strength, rigidity, impact toughness and weldability. Due to the difference of transmission medium-oil and natural gas and the difference of natural gas with rich gas and commonly used purified natural gas, as well as the difference of transmission sections (river crossing section, onshore transmission section (and areas of categories I, II, III and IV) and seabed transmission section), there are different technical requirements for steel pipes.
