Fitting for connecting to at least one pipe and method for producing a connection

Abstract

The invention relates to a fitting for connecting to at least one pipe, in particular a plastic pipe or plastic-metal composite pipe, comprising a main body (4), at least one support body (6) connected to the main body (4) and for introducing into a pipe end, and at least one press sleeve (8) connected to the main body (4) and for receiving the pipe end, wherein the press sleeve (8) has a cylindrical press section (10). The technical problem of improving the fitting for pressing, in particular with small motor-driven or hand-operated pressing tools, is achieved in that the press sleeve (8) isproduced from a metal with a micro-hardness of less than 65HV1, in particular less than 50HV1, preferably in the range between 40 and 50HV1, measured according to Vickers hardness test, and in that the ratio of the wall thickness (s) of the press section (10) to the outer diameter (d) of the press section (10) is less than 0.06, preferably in the range between 0.03 and 0.06. The invention also relates to a method for producing a connection.

Description

technical field [0001] The invention relates to a fitting for connecting at least one pipe, in particular a plastic pipe or a plastic-metal composite pipe, having a base body, at least one support connected to the base body, preferably integrally formed therewith, for inserting the end of the pipe, and At least one compression sleeve connected to the base body for receiving the pipe end, wherein the compression sleeve has a cylindrical compression section. Furthermore, the invention also relates to a method for producing a connection between a fitting and a pipe. Background technique [0002] The technical field relevant to the invention is the installation of conduit systems on the construction site, wherein conduit systems generally used for conveying and guiding liquids, consisting of pipe sections and connections, are installed. A joint is basically understood to be a connection piece of a conduit and is generally used to connect two or more pipe sections. The joint ac...

AI Technical Summary

Problems solved by technology

[0008] Known compression sleeves also do not provide or only provide insufficient guidance of the extrusion tool or only move themselves during extrusion

thus resulting in a leaky connection

[0009] Furthermore, even with holes provided in the wall of the compression sleeve, it is difficult to see the depth of insertion of the tube because the holes are too small as viewing windows

This also results in a leaky connection, since the insertion depth of the tube end cannot be adequately monitored

Furthermore, the tube can be additionally deformed and shrink further or even lead to the formation of extrusion folds when the compression sleeve is squeezed
