Welded straight seam submerged arc welded steel pipes 

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. specifications Outer diameter 508mm -1118mm (20 "-44") Wall thickness: 6.0-25.4mm 1/4 "-1" Quality standards: API, DNV, ISO, DEP, EN, ASTM, DIN, BS, JIS, GB, CSA Length: 9-12.3m (30 '-40') Grade: API5L A-X90, GB/T9711 L190-L625 JOCE LSAW pipes (bent) This is the production line for large-diameter longitudinal submerged arc welding (LSAW) pipes in China.
