Product Information:

Heat-insulated pipes - steel pipes with a diameter of 57 to 530 mm with pipе insulation from polyurethane foam (PPU) in a waterproofing cover like "pipe in pipe". Pipe PPU in a polyethylene sheath is designed for underground laying, and in galvanized sheath for above-ground laying of heating networks with a working pressure of up to 1.6 MPa and a temperature of heat carrier up to 150 C.

Insulated pipes are manufactured in accordance with GOST 30732-2006. The quality of pipes in PU foam insulation is confirmed by a certificate of conformity. All tubular products are manufactured with a moisture control system for the heat-insulating layer of the APC to determine the location of damage to the containment. 

 

Advantages:

  1. Construction time is reduced by 2.5-3 times
  2. Maintenance costs for maintenance are reduced by 9 times
  3. Reduction of heat loss by 8-10 times compared to mineral wool insulation
  4. Guaranteed service life - 25-30 years compared with 7-10 year service life of traditional networks
  5. Capital costs are reduced by 1.2 times
  6. Repair costs are reduced by 3 times.
  7. During the period of operation, monitoring of the pipe condition without opening the trench is provided.
