Thick wall welding steel pipe is thick wall welding pipe, production manufacturing process can be divided into cold pull, cold rolling and hot rolling three basic ways, steel pipe material is 10#, 20#, 35#, 45# called ordinary steel pipe, 16Mn between ordinary steel pipe and alloy steel pipe called low alloy steel pipe, steel pipe material is 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo and stainless steel pipe collectively called alloy steel pipe.

Thick wall welded steel tubes are mainly used in tap water engineering, petrochemical industry, chemical industry, electrical industry, agriculture irrigation, and urban construction. Lɔ̈ɔ̈m ye kɔɔr: Pii, pii. Gas: Gas, steam, liquefied petroleum gas. Luɔ̈ɔ̈i: Luɔ̈ɔ̈i pip, luɔ̈ɔ̈i bridge; Docks, roads, building structures tubes and so forth.

Thick wall steel pipe material domestic commonly used material is: 10# 20 mn 42crmo 36CrMo 40Cr 20Cr 15CrMo 12Cr1Mov Q235A，Q235B、0Cr13、1Cr17、00Cr19Ni11、1Cr18Ni9、0Cr18Ni11Nb、16Mn、20#、45#,Q345、L245、L290、X42、X46、X70、X80。

Thick wall steel pipe quality key to several wall thickness uniformity, thick wall steel pipe thickness cannot be controlled will directly affect the quality of steel pipe and use, thick wall steel pipe, large diameter thick wall steel pipe generally used in various mechanical processing, thick wall parts processing, thick wall steel pipe thickness uniformity will directly affect the quality of later processing parts, thick wall steel pipe thickness cannot be controlled, is the overall quality of steel pipe cannot be strictly controlled.
