ROLLER TOOL FOR FORMING GROOVES IN PIPES |
摘要 |
A roller tool for forming circumferential grooves around a pipe is disclosed . The tool is rotatable about an axis of rotation and has a circumferential surface engageable with a pipe. The tool surface includes first and second surface portions positioned in spaced relation and oriented perpendicularly to the axis of rotation. A radial surface portion extends between the first and second a surface portions and is oriented substantially parallel to the axis of rotation. An angled surface portion is positioned adjacent to the second surface portion. The angled surface portion is oriented at an angle up to about 70~ and slopes away from the second surface portion. |
