Winding 3PE anti corrosive steel pipe
3pe anti-corrosive steel pipes are pipes (steel pipes) used in different working environments. To slow down or prevent the pipes from being corroded and deteriorated by the chemical or electrochemical action of the external medium or by the metabolic activities of microorganisms, the outer wall o...Read more -
How to weld a thin metal cover to a thicker steel pipe by using MIGW or flux-cored gas shielded welding
Reason analysis: If the welding current cannot be adjusted correctly during welding, two situations may occur: one is to reduce the welding current to prevent the thin metal from burning through. At this time, the thin metal cover cannot be welded to the thick steel pipe; the other is welding Exc...Read more -
Precautions for welding stainless steel pipe
Precautions for welding stainless steel pipe 1. Power supply with vertical external characteristics is adopted, and the positive polarity is adopted for direct current (the welding wire is connected to the negative electrode). 2. Generally suitable for the welding of thin plates below 6mm, with t...Read more -
Sealing and bonding of stainless steel pipeline
