LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional term for longitudinally submerged arc welding. LSAW steel pipe is made of single medium and thick plate as raw material. The steel plate is pressed (rolled) into tube blank in the mold or forming machine, and it is made by double-sided submerged arc welding and expanded diameter. The product has a wide range of specifications, good toughness, plasticity, uniformity and density of the weld, and has the advantages of large pipe diameter, pipe wall thickness, high pressure resistance, low temperature resistance and corrosion resistance. In the construction of high strength and high quality long distance oil and gas pipelines, most of the steel pipes needed are large diameter thick wall straight seam submerged arc welded pipes

Oil casing is used to support the oil, gas wells of steel pipe, in order to ensure the drilling process and the completion of the entire well after the normal operation. Each well has several layers of casing depending on the drilling depth and geology. Casing down to use cement cementing, it and the tubing, drill pipe is different, can not be reused, a one-time consumption of materials. Therefore, the casing of the total consumption of more than 70% of the wells. Casing according to the use can be divided into: catheter, surface casing, casing technology and oil casing.

Petroleum cracking pipe is a kind of hollow long circular seamless steel pipe. Petroleum cracking pipe uses: used to transport gasoline, kerosene, diesel and other oil products, corrosion resistance, anti-wear. Petroleum cracking pipe (gb9948-83) is suitable for geological drilling and industrial drilling of the first class steel pipe.

ASTM A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines.

ASTM A106 pipe is always produced by the seamless method and can be bent, coiled and flanged.

Carbon steel pipe is made of ingot or solid round steel through perforation to make a tube, and then hot rolled, cold rolled or cold drawn to make.

A335 alloy steel pipe is an alloy steel pipe, mainly used in low and medium pressure boiler heating surface pipe and other fields. Manufacturing process: Hot rolling (extruded seamless steel pipe).
