Abstract
For forming a clamping ring 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 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 is formed. The clamping ring is used on a pipe when making a pipe connection.
Claims7
A method of forming a clamping ring to be used on a pipe when making a pipe connection, the method comprising:
- extruding a pipe from a plastic material having memory properties, whereby, while extruding the pipe, its inner diameter is formed smaller than the outer diameter of the pipe onto which the clamping ring is positioned before making the pipe connection,
- cutting the extruded pipe to form a pipe part,
- making the inner diameter of the pipe part 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 is formed at one end of the pipe part, whereby the pipe part forms the clamping ring.
A clamping ring to be used on a pipe when making a pipe connection, which clamping ring is formed from an extruded pipe by cutting the pipe into a short enough pipe part, which pipe is extruded of a plastic material having memory properties and has an inner diameter smaller than the outer diameter of the pipe onto which the clamping ring is positioned before making the pipe connection and which pipe part has been 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 the clamping ring comprises a stop edge at one end of the pipe part.
