In this article,according to the manufacturing difficulties of X70 grade hot bending bends with large diameter-thickness ratio,it reasonably improved bends unit equipment,optimized bends forming process parameters,accurately measured and controlled the temperature and speed in bends forming process. A complete set of large diameter-thickness ratio bends manufacturing process was developed, it resolved some problems,including ovality of bends body exceeding the standard requirements,the comprehensive mechanic properties not good,and other manufacturing difficulties. It adopted the above manufacturing process to conduct single and bulk production, the products accord with the requirements of Iraq MOEP Project Technical Specification for Bending Bends.
