The generation of steel strip delamination defect and its influence on steel pipe quality
Delamination is caused by shrinkage defects in the steel ingot. After the steel ingot with a shrinkage cavity is rolled into a steel strip, a layer is formed in the middle of the section. The internal delamination of the wide coil can be exposed to the edge of the strip after slitting, but it is ...Read more -
Production characteristics of stainless steel seamless pipe
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 capillar...Read more -

What should be paid attention to when welding galvanized steel pipe
What should be paid attention to when welding galvanized steel pipe 1. The premise must be polished The galvanized layer of the weld must be polished away, otherwise air bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce the rigidity. 2. The welding c...Read more
