Welded steel pipe refers to a steel pipe with seams on the surface that is welded after bending and deforming a steel strip or steel plate into a circular, square or other shape. According to different welding methods, it can be divided into arc welded pipes, high frequency or low frequency welded pipes, gas welded pipes, etc. According to the shape of the weld, it can be divided into straight seam welded pipe and spiral welded pipe.
By material: carbon steel pipe, stainless steel pipe, non-ferrous metal pipe, rare metal pipe, precious metal pipe and special material pipe
By shape: round tube, square tube, rectangular tube, special-shaped tube, CUZ profile
welded steel pipe production
The tube blank (steel plate or strip steel) is bent into the required tube shape by different forming methods, and then its seams are welded by different welding methods to make it a tube. It has a wide range of sizes, from 5-4500mm in diameter, and from 0.5-25.4mm in wall thickness.
The steel strip or steel plate is introduced into the welded pipe making machine through the feeder, and the steel strip is extruded through the rollers, then the mixed gas is used to shield the welding and circular correction, and output the required length of the pipe, cut by the cutter mechanism, and then go through the straightening machine Straighten. The spot welding machine is used for spot welding connection between strip heads. This type of pipe making machine is a comprehensive complete set of equipment that continuously welds strip materials into pipes and adjusts the circle and straightness.
