Product Description

UOE LSAW Steel Pipe

UOE mill adopts the most advanced technology and process, with high production efficiency, stable product quality, and equipped with complete testing equipment. The UOE mill adopts U&O molding, and the formed pipeline is welded to the outside through five internal welding stations using three wires, and to the outside through four external welding stations using three wires. According to different customer requirements, welded pipes can be expanded through mechanical or static pressure expansion to improve dimensional accuracy and eliminate residual stress.
