Steel pipe processing furnace:1. In the process of heat treatment, the workpiece that is easy to deform should be stopped on the special fixture2. The workpiece should be placed in the effective heating zoneWarm-up:1. For workpieces with complex shapes or sharp changes in cross-section and large eff

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

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

The straight seam steel pipe structure can adopt a circular pipe structure or a rectangular pipe structure according to the specific conditions of the component's stress, supply conditions, manufacturing and processing conditions, and cost, or a mixture of the two types of steel pipes. When mixed-us
