| Abstract: | It briefly introduces the importance of pre-bending process for production of longitudinal submerged arc welding pipe,function of pre-bending and pre-bending procedure,and analyzes main pre-bending process parameter,such as radius of curvature of upper mould,pre-bending length and pre-bending coiling angle and pre-bending force,etc.,and infers calculation formula for each process parameter.Pre-bending quality all meet process requirements by using these pre-bending process parameters determined by inferred formula,practices for two years production proves that those pre-bending parameters determined are right. |
