Classification of production methods of stainless steel seamless steel pipe: seamless pipe - cold drawn pipe, extruded pipe, cold rolled pipe Stainless steel seamless pipe is a long strip of steel with a hollow section and no joints around it.The manufacturing process and flow of seamless steel pipe

A spiral steel pipe is a long strip of steel with a hollow section and no seams around it. The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water, and certain solid materials. Compared with solid s

1. The power supply with vertical external characteristics is adopted, and the positive polarity is used for DC (the welding wire is connected to the negative pole)2. Generally suitable for welding thin plates below 6mm, with the characteristics of beautiful weld shape and small welding deformation3

All-position automatic welding of steel pipe means that when the steel pipe is relatively fixed, the welding trolley drives the welding torch to move around the pipe wall along the track, to realize automatic welding. Generally speaking, the all-position automatic welding device is composed of a wel
