Connecting element and pipe connection comprising said connecting element

Abstract

The invention relates to a connecting element (1) for producing a pipe connection between the connecting element (1) and a plastic pipe fitting or a metal-plastic composite pipe fitting, said connecting element (1) having at least one support body (2, 2a) for sliding to a pipe fitting end (14), said support body being provided with a plurality of circumferential outer ribs (3, 3a, 3b, 3c), wherein the at least one support body (2, 2a) has a central axis (4) and an open end (8), and at least two circumferential outer ribs (3, 3a, 3b, 3c) are inclined at an acute angle (9, 9a, 9b, 9c) with respect to the central axis (4), wherein the acute angle (9, 9a, 9b) at which the circumferential outer rib (3, 3a, 3b) is inclined with respect to the central axis (4) is different from the acute angle (9a, 9b, 9c) at which at least one of the circumferential outer ribs (3a, 3b, 3c) is inclined with respect to the central axis (4), said at least one circumferential outer rib being spaced further from the open end (8) than the circumferential outer rib (3, 3a, 3b).

Description

technical field [0001] The invention relates to a connecting element for establishing a pipe connection between a connecting element and a plastic pipe or a metal-plastic composite pipe, wherein the connecting element has at least one support for sliding onto the end of the pipe, the support The body is provided with a plurality of circumferential outer ribs, wherein the at least one support body has a central axis and an open end, and at least two circumferential outer ribs are inclined at an acute angle relative to the central axis. Furthermore, the invention relates to a pipe connection between the end of an all-plastic pipe or plastic composite pipe and a connecting element, wherein the pipe connection comprises the end of an all-plastic pipe or plastic composite pipe and such a connection element. Background technique [0002] Such connecting elements and pipe connectors comprising such connecting elements are disclosed in the prior art. The pipe end is fixed to the c...

AI Technical Summary

Problems solved by technology

In addition, when cutting especially metal-plastic composite pipes, burrs may appear which make it more difficult to insert connecting elements into the severed pipe ends

Furthermore, the feasibility of inserting the connecting element into the end of the pipe may also be adversely affected by the cutting of the pipe, since the ovality of the pipe may be further increased by the effect of the pipe cutter
