PE-ST-PU-PE pipes and ST-PU-PE pipes

PE-ST-PU-PE pipes and ST-PU-PE pipes

„ELPLAST+” Sp. z o.o. manufactures PE-ST-PU-PE pipes and fittings, and also ST-PU-PE pipes and fittings. ST-PU-PE pipes consist of a steel carrier pipe, an insulation layer made of slow-burning polyurethane foam and a polyethylene casing pipe (PE-NP-AS).

PE-ST-PU-PE pipes has additionally an inner lining made from a polyethylene pipe.


Advantages of PE-ST-PU-PE pipes and ST-PU-PE pipes:

  • efficient thermal insulation – connections without thermal bridges (in case of the insulated joint)
  • possibility of insulating a joint – complete insulation tightness
  • no corrosion in the external casing pipe

Additional advantages of PE-ST-PU-PE pipes:

  • high smoothness of the PE pipe internal surface resulting in lower resistance of flow
  • high resistance to abrasion caused by liquids containing suspended solids
  • high chemical resistance to the vast majority of substances present in transported media
  • no encrustation – hydraulic parameters are constant in time
  • no corrosion of the carrier pipe
  • excellent thermal insulation – low thermal conductivity coefficient
  • longer life in comparison to steel pipes
