Welded Steel Pipe

Video Description

Product Description

We can produce and supply various of weld steel pipes, such as LSAW Steel Pipes, SSAW Steel Tubes, ERW Steel Pipe, .etc.
Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, generally with a length of 6 meters.
Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of the weld seam. Classification by production method: process classification – arc welded pipe, electric resistance welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.
Welded pipes with smaller diameters adopt straight seam welding, and welded pipes with large diameters mostly use 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 mine fluid Conveying welded steel pipes, galvanized welded steel pipes for low-pressure fluid transportation, electric welded steel pipes for belt conveyor rollers, etc.
Commonly used materials for welded pipes are: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.
