The Basic Process of High-frequency Welded Pipe Sizing
The sizing of high-frequency straight seam welded pipes (ERW welded pipe) refers to the rolling of welded pipes after welding by rollers of a specific pass, and the round or special-shaped pipes of ir...
Multi-wire Submerged Arc Welding Process of Longitudinally Welded Pipe
Because the multi-wire submerged arc welding of longitudinally welded pipes has the characteristics of large undercooling and fast welding speed, the equilibrium state is basically eliminated. If the ...
The Significance of Studying the Heat-Affected Zone of Welded Pipe Welding
Welding heat-affected zone（HAZ) is different from welding seam. Welding seam guarantees performance requirements through chemical composition adjustment, redistribution and proper welding process, whi...
Comparison of Straight Seam Steel Pipe and Spiral Steel Pipe
The production process of straight seam steel pipes is relatively simple, and the main content of the production process is high-frequency welded straight seam steel pipes (ERW) and submerged arc weld...
Difference between Carbon Steel Seamless Pipe and Stainless Steel Seamless Pipe
The difference between carbon steel seamless pipe and stainless steel seamless pipe mainly refers to the difference in design rules between stainless steel and carbon steel, which means that the desig...
What are the Precautions for Ordering Seamless Steel Pipes?
"Ordering" is the beginning of cooperation between the supplier and the buyer. In order for the buyer to obtain steel pipes that meet the requirements for use, and for the supplier to produce steel pi...
