Abstract
The invention concerns a method for the manufacture of individual pipe sections of a pipe formed by a product pipe having at least one channel running along the product pipe. Surrounding the product pipe and the channel is a pipe jacket filled with an insulating mass which exhibits a flowability only in the processing condition. The channel running along the product pipe is formed by the outline of a core of material in place during addition of the insulation.
Claims14
A method for the manufacture of individual pipe sections comprising a product pipe having a jacket surface and at least one channel running along said jacket surface of said product pipe comprising the following steps:
- a) arranging a core on said jacket surface of said product pipe such that said core is disposed on said product pipe in a linear manner;
- b) inserting said product pipe with said core into a jacket pipe;
- c) filling said jacket pipe with an insulating mass that exhibits a flowability only during processing;
- and
- d) removing said core from said jacket pipe.
A method for the manufacture of individual pipe sections comprising a product pipe having a jacket surface and at least one channel running along said jacket surface of said product pipe comprising the following steps:
- a) arranging a core on said jacket surface of said product pipe such that said core is disposed on said product pipe in a linear manner;
- b) inserting said product pipe with said core into a jacket pipe;
- c) filling said jacket pipe with an insulating mass that exhibits a flowability only during processing;
- and
- d) applying a thin coating to the outside surface of said core and the portion of the surface of said product pipe which touches said core.
A method for the manufacture of individual pipe sections comprising a product pipe having a jacket surface and at least one channel running along said jacket surface of said product pipe comprising the following steps:
- a) arranging a core, having a hollow profile open toward said product pipe, on said jacket surface of said product pipe such that said core is disposed on said product pipe in a linear manner;
- b) inserting said product pipe with said core into a jacket pipe;
- and
- c) filling said jacket pipe with an insulating mass that exhibits a flowability only during processing;
- wherein an element comprising a spring-elastic material is disposed within said hollow profile of said core opposite said product pipe.
