Polyurethane foam heat-insulating manufactures

  Purpose

 
Polyurethane foam heat-insulating manufactures (PUF) are used to insulate gas and oil lines,
  hot and cold water pipelines, chemical and petrochemical utility networks , tanks, reservoirs ,
  capacities and other industrial objects , cryogen and refrigerator engineering against heat within
  the temperature range from -250°С to +160°С. The application of combined heat insulating
  construction from mineral cotton and polyurethane foam enables to use it at the objects with the
  temperature approaching 250°С.
 
  Characteristics


Manufactures
:
  • Polyurethane foam heat-insulating manufactures are made in the form of semicylinders,
  • T-pipes,
  • offsets,
  • prefabricated constructions to insulate stop valves,
  • plates and other manufactures against heat under the customer’s technical requirements.

Properties
  • In its thermal-physical service properties polyurethane foam manufactures considerably leave behind those of conventional heat insulating constructional materials
  • PUF conductivity factor is 2-3 lower than that of mineral cotton and 6 times as low as foamed concrete
  • Calculations under SNiP 11-3-79 "Construction thermo technique " (issue 1995 taking into account variation N3) and SNiP 2.04.14-88 “Heat insulation of equipment and pipelines" (with variation N1 11.03.95) show that 10mm thick PUF layer is equivalent to 140 mm of brick laying, 30 mm of mineral cotton
  • PUF –insulation possesses good water-weather resistance , is environmentally friendly and corresponds to the requirements of sanitary and fire protection norms
  • PUF –insulation guaranteed service life makes 25-30 years
  • PUF manufactures are non-toxic and can be applied in inhabited and communal buildings in accordance with the permission of Ministry of Health Protection of Belarus and Russian Federation. PUF systems have hygienic certificates.
