erw pipes and tubes straight seam

How is seamless pipe formed?How is seamless pipe formed?Seamless pipe is formed when steel in the billet is heated and then either pushed or pulled over a mandrel with a piercing point located in the center of the billet. This produces a hollow tube or shell.What's the Difference Between ERW Pipes and Seamless Pipes? What is the difference between ERW and seamless pipes?What is the difference between ERW and seamless pipes?The biggest visible difference between ERW pipes and seamless pipes in structure is that ERW pipe has a welding seam which is produced by the welding process while seamless pipe doesnt.What's the Difference Between ERW Pipes and Seamless Pipes? What is the difference between EWR and seamless pipe tube billet?What is the difference between EWR and seamless pipe tube billet?Besides, the ERW pipe tube billet is made of hot-rolled steel strip with cold rolling process while the seamless pipe tube billet is produced in hot rolling condition. The situation where seamless pipe tube billet is produced has some negative effects on the grain size, thus resulting in a less satisfying performance.What's the Difference Between ERW Pipes and Seamless Pipes?

Differences between ERW Steel Pipe and HFW Steel Pipe

ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.
