METHOD OF FORMING A CLAMPING RING AND A CLAMPING RING |
摘要 |
For forming a clamping ring (6) first the pipe is extruded. The extruded pipe is cut to form a pipe part. While extruding the pipe, its inner diameter is formed smaller than the outer diameter of a pipe (1) onto which the clamping ring is positioned before making a pipe connection. The inner diameter of the pipe part is made larger by removing material from the inside of the pipe part but only over part of the length of the pipe part such that a stop edge (7) is formed. The clamping ring is used on a pipe when making a pipe connection. |
