Such conduits have shown their advantages in installation technology. In many cases of application, and in particular in the case of drainage pipes, it is necessary to provide such a pipe with Yarine and sound insulation. For this purpose, the known line pipes were provided with an additional insulating layer after laying, and it was then on this line pipe

Plastic jacket and an intermediate deminating layer are formed from rigid plastic foam, the plug-in sleeve on each
one pipe section end molded into the inner metal jacket
and the tube plug-in end is formed at the other end of the tube section by the inner metal jacket. The pipe sections of such a conduit pipe are not only completely producible from the outset and at the factory with complete insulation and a closed outer ring, but it can

The pipe according to the invention is particularly suitable for sewage pipes, namely in particular as a protective and rainwater pipe for internal and external drainage. As a result of the construction of the pipe according to the invention, heating elements, in particular electrical resistance heating elements and heating jackets, can also be accommodated in the pipe sections during prefabrication in order to ensure proper water drainage even in extreme weather conditions.

According to one embodiment of the invention, the inner and outer metal jacket are each designed as a steel tube. j This results in a particularly high strength of the conduit pipe

achieved, which is particularly important when laying freely over longer lengths and when laying is subject to impact is. 'Particularly high demands are placed on the corrosion resistance of the conduit pipe, so it is expedient if, in a further embodiment of the invention, the inner and outer steel tubes are hot-dip galvanized and at least the inner steel tube is additionally coated with plastic on at least its inner wall. Hot-dip galvanizing in connection with the plastic coating offer a maximum of corrosion protection.

The Zwischendämnscljicht is expediently made of polyurethane; -arcschaura, which has proven to be particularly expedient both in terms of its manufacturing properties and in terms of its usage properties, therefore on the one hand for the factory prefabrication, or by appearance. ^: .-iu we η particularly suitable and on the other hand a high-quality ',, "door insulation connects with the greatest possible sound insulation and ultimately leads to an intimate adhesive bond between the outer and inner 3-metal jacket, especially when using steel pipes the invention ensures the greatest possible stability during transport, during laying or assembly and during operation.

In the drawing; is an essential part of a conduit pipe according to the invention for the explanation of the invention shown, in the left half in longitudinal section and in the right half in side view.

The line pipe shown in the drawing has a pipe section 1 and a pipe section 2 and a general with 3 designated pipe connection.

At the jc-Weil's other pipe section end, in the exemplary embodiment on At the end of the pipe section 1, a pipe insertion end 4a is formed by the inner metal jacket 4. In the annular gap between Plug-in socket 5c and plug-in end 4a have a sealing sleeve 10 inserted in the usual manner.

In, there is a t-nde of each pipe section 1 and 2, respectively the Einstecklauffe 5a molded in the prefabrication. In the The other end of each pipe section is prefabricated ! n with inner jacket 4 or 5 and outer jacket 6 or manufactured.
