Advantages of SML Steel Pipe and ERW Steel Pipe

ERW (high frequency straight seam welded pipe) steel pipe blanks are manufactured by hot-rolled steel strip cold rolling forming, while SML (seamless steel tube) steel pipe blanks are formed by perforating round steel in the hot-rolled state.Obviously, the SML formed in the hot-rolled state has a large gap between the grain size and the denseness of the structure of the tube compared with the China Erw Steel Tube, Erw Steel Tube Manufacturers China Erw Steel Tube manufacturers - Select 2020 high quality Erw Steel Tube products in best price from certified Chinese Steel Tube manufacturers, Steel Tubes suppliers, wholesalers and factory on Made-in-China
