Embodiment Construction

[0040] below, through Figures 1a to 6b A system for producing a non-detachable workpiece connection according to the invention is illustrated by way of example, in which embodiments of the power transmission part 2 and the sliding sleeve 4 are used.

[0041] Figure 1a Four workpieces are shown in cross section: fitting 6 , power transmission 2 , sliding sleeve 4 and tube 8 .

[0042] The fitting 6 has a structurally shaped support body 10 made of plastic, for example PPSU, and a body 12 made of metal. exist Figure 1a , the support body 10 and the body 12 are still separated from each other. The fitting 6 also has an axial abutment face 14 on the body 12 . In this particular exemplary embodiment, the structural shape of the support body 10 consists of five annularly surrounding grooves which are delimited from one another by four interposed, annularly surrounding separating plates. The inner enclosing surface of the support body 10 is substantially cylindrical, wherein, h...

Abstract

The invention relates to a fitting (6, 61) for sealing connection with a pipe end of a pipe having a plastic composition, which has a body (12, 80) and a support body (10, 82), wherein the body (12, 80 ) is made of metal, the support (10, 82) is made of plastic as a separate part from the body (12, 80), and the body (12, 80) is on the inside and the support (10, 82) is on the outside There are structural parts (46, 48, 84, 86) which seal the connection of the body (12, 80) and the support (10, 82). The invention also relates to a system with the aforementioned fittings, composite or multilayer tubes and sliding sleeves, and also to a system with the aforementioned fittings, plastic pipes and sliding sleeves. The invention further relates to the use of fittings for connection to composite pipes or multilayer pipes, and to the use of fittings for connection to plastic pipes.

Description

technical field [0001] The invention relates to a fitting for a sealed connection to a pipe end of a pipe having a plastic component, which has a body and a support body, wherein the body consists of metal. The invention also relates to a system with the aforementioned fittings, composite or multilayer tubes and slip-on sleeves, and also to a system with the aforementioned fittings, plastic tubes and slip-on sleeves. Furthermore, the invention relates to the use of fittings for connection to composite pipes or multilayer pipes, as well as the use of fittings for connection to plastic pipes. Background technique [0002] A fitting for a sealed connection to a pipe is known from the document EP 0 728 979 A1 in the prior art. In this case, the fitting (or the connecting piece) consists entirely of metal and has a support body (or cylindrical section) onto which the tube is plugged. A compression ring is connected to the fitting and the pipe from the outside, which is pressed ...
