DE7532003U - CONNECTING RING FOR PIPES - Google Patents

Description

Connection Hungarian «for Tube

The innovation concerns a connecting ring with a (D-profile, especially for thin-walled pipes.

Connecting rings are known which consist of a ^{part arranged between the pipe ends when used in pipes 1} * which are to be connected to one another and a part extending along the inner walls of the pipe.

The object of the innovation is to improve such connecting rings so that a pipe connection that is optimal in terms of speed and simplicity is possible.

To solve the problem, the innovation is a connecting ring from, with a part arranged between the pipe ends when used in pipes to be connected to one another and a part extending along the pipe walls, the part arranged between the pipe ends with its free part The end protrudes from the pipe walls and is characterized in that the part running along the pipe walls is conical on its side located on the pipe wall, namely up to the one arranged between the pipe ends Part and up to the pipe wall.

The innovation has the advantage that, in addition to the omission of a welding filler material, not only tubes are involved Slightly attach round ends, but also put tubes with non-round ends on the connecting ring can be, and that the pipe ends, when sip rest on the part of the connecting ring lying between them, round and are fixed in their welding position.

It is useful if the connecting ring is made of the same material as the one to be connected Drill.

In the drawing the connecting ring is according to the innovation explained in more detail using an exemplary embodiment:

The figure shows the connection ring 1 according to the invention between two tubes 2 ₄ $ to be connected to one another.

The connecting ring inserted between the tubes 2, 3 consists of a ring extending radially outward Area 4- and one located within eier tubes 2, 3 axially extending Boreich 5 · The area 4 has an between the pipe walls on the pipe outer circumference protruding extension 6. The one that protrudes beyond the outer circumference of the pipe Renewal. 6 of the area 4 forms the welding material for welding the connecting ring 1 with the Pipes 2, 3. Area 5 - 3 -

is conical on its side facing the pipe wall. The conical part runs up to area 4 and extends to the pipe wall.

To connect the pipes 2 »3 to each other, they are in a device, not shown, is drawn onto the connecting ring 1 and against its area 4. In this In position, the pipe ends are round and also fixed flush with one another. The tubes 2, 3 are then connected to the Material of the protruding beyond the pipe outer circumference Part of the area 4 welded.
