Make an Inquiry for Quality Q345B straight seam pipe submerged arc welding pipe large diameter Q235 straight seam pipe at ASTM A572 Gr 50 vs Q345B - American Welding SocietyMay 07, 2013 · Hello everybody:The Technical Specifications for metal works (gates, trash racks, etc.) of a hydro project indicate, particularly, for the gates to use steel ASTM A572 Gr 50 or its equivalent S355JR according to EN 10025. The Contractor is trying to change that material to steel Q345B (chinese material and code). At the same time, this Contractor says that they, in China, have developed Longitudinally Submerged Arc Welded Steel pipes, LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided Carbon Steel Welded Saw Spiral Steel Pipe - China SHANGH 1.The spiral steel:spiral steel coil as raw materials is steel, often warm extrusion, with automatic double- wire submerged arc welding process double- sided spiral welded steel pipe; 2.

Experimental research and analysis on residual stress Nov 01, 2019 · A total of 45 circular steel tubes were measured in this study, as indicated in Table 1 Table 2, Table 3, Table 4 and Fig. 1. According to manual metal arc welding, during the SAW process, the welding groove with an angle of 60°70° was divided into four sections, namely the final pass, second pass, root pass, and contact region. To prevent flux and welding slag from falling into the tube
