Product Description

Insultherm® Pre-insulated Piping systems for District Cooling, Underground chilled water pipeline, Industrial Application and other energy related applications. The product consists of a carrier pipe, insulation and jacket pipe. The insulation are available in different thickness as well as densities range from 35Kg/m3 to 80 Kg/m3.

Surface Finish

Insultherm® The steel core pipe external surface will be cleaned and coated with red-oxide or the core pipe external surface will be grit-blasted to SA 2½ near white metal finish, then coated by airless spray with self-priming Polyamide/Polyamine epoxy to total DFT of 125 microns nominal 50 mm shall be kept bare (uncoated) from both pipe ends for joint welding as specfied.

Insulation

The thermal insulation will be rigid cellular 100% CFC-free Polyurethane or Polyisocyanurate foam, as per EN 253 factory injected between core pipe and outer protective Jacket, having a density of 35Kg/m3, 50Kg/m3 or 60 Kg/m3 and thermal conductivity of 0.028 W/m.K maximum at mean temperature of 24 oC. Typical operating temperature is between -20 to +120 oC

Densities

All Fittings will be factory insulated black steel, butt-welding type, with similar wall thickness of the carbon steel pipes conforming to ASTM A 234 WPB and dimensions according to ANSI/ASME B16.9 with 200-300 MM long beveled end steel pipe extended to each end. All fabrication welded joints are 100% non-destructive testing prior to insulation.
