The production characteristics of stainless steel welded pipes The continuous roll forming into stainless steel welded pipes below φ219mm is similar to the high-frequency straight seam welded pipes above φ219mm using pressure forming (UOE) or spiral welding (see spiral welded pipes). The capillary i

Steel pipe anti-corrosion coating process 1: Adopt the curtain coating method, before coating, after coating, and in the middle of the roller conveyor, to form a coating film. Then the shift fork is transferred, the hook-shaped chain is rolled and conveyed, and the steel pipe enters the steam oven h

The steel plate is first pressed into a U shape in the forming die, and then pressed into an O shape, and then the inner and outer submerged arc welding is performed. After welding, the diameter is generally expanded at the end of the full length, which is called the UOE welded pipe, and the one tha

There are many types of anti-corrosion coatings, and their properties and uses are different. The correct selection is crucial to the anti-corrosion effect and service life of the coating. When choosing:1. The nature of the surface material of the coated objectFor example, iron red and red lead prim
