Product Description

Pre-Insulated Seamless Carbon Steel Pipe

The pre insulated pipe system is made up of steel carrier pipe, 100% CFC free polyurethane insulation foam and seamless solid wall HDPE jacket. Steel carrier pipe may vary according to project specification; from ERW (Electric resistance welded), SAW (Submerged arc welded) or Seamless pipes with wall thickness from Std, Sch 40, XS.

The insulation is made of 100% CFC free polyurethane foam. The required amount of foaming mixture, usually 25% over packed, is injected into the cavity between the steel core and the casing pipe via the injection hole in the metal end caps at the top of the pipe assembly. Air vent plugs are fitted on the metal end caps to dispense the air entrapped.
