Pre insulated pipe systems for district heating

For the transport of district heating energy over long distances a complex, mostly underground pipe system is required.
High demands are made on both, the medium pipe and the pipe insulation.

aquatherm offers with the factory insulated aquatherm blue pipe TI-fiber composite pipes the ideal district heating pipes for heating systems, which are operated with working pressures up to 20 bar and working temperatures up to 90° C.

The insulated aquatherm blue pipe TI fiber composite pipes are also used as cooling- and refrigerant agent pipes. The pipe insulation is factory-made with PUR rigid foam that surrounds the medium pipe all over. To protect the insulation layer outward against mechanical or weather-related influences, the outside coating consists of a PEHD-protection pipe.

Fittings such as elbows, bends or tees are insulated at the factory in the same design. The joints between pipe and fitting are manufactured locally at the site in the pipe dimension 32 up to 125 mm by socket welding and in the dimension 160 up to 315 mm by butt-welding process.

The insulation of these joints is done by insulation sockets that enable a continuous insulation of the district heating pipeline.

aquatherm district heating pipes are available in length of 5.8 m and 11.6 m. We offer fittings with leg lengths of 0.5 m and 1.0.

Special designs on request.
