"Socket pipe made of concrete or the like."

The innovation relates to a socket pipe made of concrete, Stoneware or the like with an inner coating made of plastic.

Socket pipes made of concrete, stoneware or the like are known and it is known to have these pipes for reasons of corrosion with an inner coating of a corrosion-resistant To provide plastic, with the known arrangements problems in terms of sealing in the area the transitions between two pipe elements arise, since in this area so far for a careful sealing between the corrosion-resistant coatings not in Sufficient care could be taken so that in these areas the corrosive to lead in the pipe Medium could come into contact with the concrete.

The innovation is based on the task of creating an arrangement in which a perfect seal in the Area of socket connections created automatically and on the other hand, the production of such corrosion-resistant pipes is to be improved.

This object on which the innovation is based is achieved by the features mentioned in the claims, i.e.

It is proposed that the main pipe made of concrete or the like be molded onto the inner pipe and that the inner tube is a self-contained raw represents shaped body which protrudes on the insertion side of the pipe over the length of the main pipe, wherein the main pipe in the area of the socket end a multiple

has step-shaped Huffenerweiteruhg and the inner tube forms a socket end which has at least one step and hugs the first step of the main pipe.

By this arrangement, an interlocking of the Plastic existing inner tubes reached into one another. Are these interlocking plastic parts, i. the spigot end and the socket end of the inner pipe machined accordingly precisely, one already takes place here tight connection.

In addition, it can be provided according to the innovation that a ring seal in the socket area of the inner pipe is arranged, this ring seal according to a further essential feature of the innovation in a corresponding formed.Ringnut can lie.

Embodiments of the innovation are based on the following of the drawings. The drawings show in

Fig. 1 shows a first embodiment of two pipes to be connected to one another, in

Fig. 2 on a much larger scale Socket end of the pipe components and in

3 shows a modified version, again on a large scale Execution form of the socket ends.

In the drawings, 1 denotes a socket pipe, that of a concrete or the like. Existing Hatiptrohr and an inner body 3 / wherein this inner body is tubular. The inner body 3 has an insertion end ″ 4 protruding beyond the insertion end of the main pipe 2 and a fine socket end 5 ~

-Z-

The main pipe 2 is also equipped with a socket end 6, which in the embodiment shown in FIG is designed in a double-step shape, i.e. the step 7 and the step 8 are formed, the socket end 5 of the inner body 3 only in the Area of the step 8 of the socket end of the main pipe 2 is arranged.

When the two tubes are pushed into one another, the insertion end 4 engages in the snuff part 5 of the inner tube 3 and seals here, while the insertion end of the main pipe 2 in the second stage 7 of the socket end 6 of the Rohres engages.

In the embodiment of FIG. 2, the overall construction the sleeve multi-stage, with a corresponding conically widening design of the Inner body 3 at 9 enables easier insertion of the associated insertion end 4 of the inner body In an annular groove 1o, an annular seal 11 is arranged, which is connected to the outside of the insertion end 4 of the inner body 2 comes into contact. In addition, is in the socket of the main pipe a rolling ring seal 12 is provided. Fig. 3 shows that the sleeve of the inner body 3 can also be designed in several stages in order to achieve an additional and increased seal here.
