Astm A53 Lsaw Steel Pipe For Construction And Structure
ASTM A53 LSAW Steel Pipe Used For Construction And Structure Pipe
LSAW (Longitudinal Submerged Arc Welding) pipes are straightly welded; it is widely used in heavy industry to convey oil, coal slurry, etc. Under strictly operation according to ISO9001:2008 International Quality System, Huayang has always held the management concept of “quality first, credit first, customer first” to develop constantly, we have always persisted in scientific innovation.

UOE LSAW STEEL PIPES
The UOE mill features the most advanced technology and process, achieves high production efficiency, stable product quality and is equipped with complete inspection equipment. UOE mill adopts U & O forming, the formed pipes are welded inside through five internal welding stations with three wires, and welded outside through four external welding stations with three wires. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expand to improve dimensional accuracy, and eliminate residual stress.
