Mills produce two types of line pipe, seamless and welded. Seamless pipe is formed from a cylindrical bar of steel. The bar is heated to a high temperature and then a probe is inserted to create a hole through the cylinder. The cylinder is then transferred to rollers which size the cylinder to the specified diameter and wall thickness. A few mills can produce seamless pipe up to 24-in in diameter. For small diameter pipe, seamless pipe is common.

Carbon steel pipes are divided into hot rolled and cold rolled (pulled) steel pipes. Hot rolled carbon steel pipeis divided into ordinary steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe, etc. Cold rolled (dialed) carbon steel pipeis divided into ordinary steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, but also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe

ASTM A333 Standard Specifications For Seamless And Welded Steel Pipe For Low-Temperature Service.

Tubing used for mechanical and light gauge structural applications. Mechanical tube is produced to meet specific end use requirements, specifications, tolerances and chemistries. This allows for more specific property uniformity throughout the tube compared to standard pipe or tube. While Mechanical tube can be produced to standard specifications when requested, it is often produced to “typical” properties that focus mainly on the yield strength for a precise size and wall thickness. In some applications with severe forming, yield strength may not even be specified and the mechanical tube is produced to be “fit for use”. Mechanical tubing encompasses a wide range of both structural and non-structural applications

Electric Fusion Welding (EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the work piece so that the work piece leaving the melt, the formation of the weld. lt is mainly used for welding dissimilar steel welding sheet or which high power density, metal weldment can rapidly heated to high temperatures, which can melt any refractory metals and alloys. Deep penetration welding fast, heat-affected zone is extremely small so small performance impact on the joints, the joint almost no distortion. Bu tit has a requirement on a special welding room because welding using X-rays.

ERW steel pipe is Electric Resistance Welding, which is different from the welding process of ordinary welded pipe. The weld is formed by melting the base material of the steel strip body, and its mechanical strength is better than that of ordinary welded pipe. ERW steel pipe has the advantages of using hot-rolled coil as raw material, the uniform wall thickness can be controlled at about ±0.2mm, the two ends of the steel pipe are in accordance with the American APL 5L standard or GB/T9711.1 standard, the pipe end is beveled, and the length is delivered. Etc. In recent years, various natural gas pipeline network projects and gas companies have widely adopted ERW steel pipes as the main steel pipes in urban pipeline networks.
