| Abstract: | This paper introduces a new method of designing welded pipe pass,this method replaces double radius curve with multiple radius curve to solve uneven wear and high consumption of roller in welded pipe production.It is proved by practice that the multiple radius pass method can effectively reduce roller and electricity consumption and improve product quality.And as a new technology,it can be adopted by enterprises to save energy and enhance efficiency. |
