Pipes in isolation PPU in PE to a cover
The pipe the isolated PPU is an innovative product which already managed to prove the efficiency during the laying and operation of pipelines. Pipe PPU in a polyethylene cover is intended for laying in a trench without installation of drainage trays.
The product consists of four main parts: the internal working pipe made of steel, a polyurethane heater, the SODK system and an external polyethylene pipe.
The main advantage of a pipe to the cover isolated by a polyurethane sealant in PE is that for its laying it is underground not necessary to prepare special drainage trays - the pipeline is laid directly in the dug trench. Thanks to it the cost of installation works, and also time of their performance are reduced by 20 - 30 percent.
The polyurethane sealant became the second powerful advantage of a product - it possesses excellent operational characteristics. Material practically does not absorb moisture, does not lose the qualities over time. But the most important is the fact that PPU has low heat conductivity thanks to what losses of heat in the pipeline do not exceed 2% .
Thanks to SODK the problem of timely identification of damages of the pipeline and determination of their coordinates is solved.
Pipes in isolation PPU in OTs to a cover
Pipe PPU in OTs is intended to a cover for land laying on support. It is made on perfectly proved "pipe in a pipe" technology - the internal steel pipe is inserted into an external galvanized pipe. Between them centralizers are established, SODK is laid, and all space is filled in with a polyurethane sealant which quickly foams and strongly connects internal and external covers.
Application of a steel pipe in OTs to a cover has a number of advantages:
- time of installation works is reduced by 30% ;
- in spite of the fact that pipe cost in PPU is much higher usual, the total price of the laid pipeline when using this product will be 20 - 30% lower, in comparison with standard methods. It is caused by reduction of time of installation works and lack of need to use additional heat - insulating materials;
- the system of operating remote control allows to reveal in due time violations of integrity of an internal pipe or an external cover;
- the polyurethane foam heater keeps 98% of heat - it bears additional benefit from operation of the pipeline;
- the pipe with PPU isolation in OTs to a cover has the big resource of operation reaching 30 years.
Example of designation:
Pipe of St of 159h4,5 - 1 - PPU - PE GOST 10705 - 80
Steel electrowelded pipe in accordance with GOST 10705 - 80
with a diameter of 159 mm, wall of 4,5 mm thick,
the preisolated PPU, the first type of isolation
in a polyethylene cover with a diameter of 250 mm.
At the request of the Customer perhaps:
isolation of a pipe in accordance with GOST 8732 - 78, 3262 - 75, 20295 - 80,
use of a pipe of any brand became (09G2S, 17G1S, St 20),
production of two - three - pipe system in one cover.
