GROOVE DESIGN FOR MANUFACTURE OF HEAVY-WALL STAINLESS STEEL WELD PIPE

By means of W groove with the formation section modified,it can be done to prevent the strip from being displaced and scratched during welding formation process in manufacturing heavy-wall stainless steel weld pipe. In addition,the formation operation will be very consistent and the welding quality and visual quality of the pipe will be very good. This groove design method is detailed in the paper.
