    Commonly used welded pipe materials are: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.

    The billet used for welding steel pipe is steel plate or strip steel, which is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding process. Because of its different welding forms are divided into straight seam welded pipe and spiral welded pipe two kinds. Because of the shape of its end, it is divided into circular welded pipes and special-shaped (square, flat, etc.) welded pipes.

    Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, generally 6 meters. Welded steel pipe production process is simple, high production efficiency, variety specifications, less equipment investment, but the general strength is lower than seamless steel pipe.

    Small diameter welded pipe adopts straight seam welding, large diameter welded pipe adopts spiral welding. According to the shape of the end of the steel pipe, it is divided into circular welded pipe and special-shaped (square, rectangular, etc.) welded pipe; According to different materials and uses, it is divided into welding steel pipes for mining fluid transportation, galvanized welded steel pipes for low pressure fluid transportation, and electric welded steel pipes for belt conveyor rollers. According to the specification and size table in the current national standard, the external diameter * wall thickness is sorted from small to large.
