Product Description

Pre-Insulated Polyurethane Foam Pipe Shell Closed Cell Waterproof Thermal Insulation Section

Product Description

Pre-Insulated Polyurethane Foam Pipe Shell is a rigid PUR pipe section that wraps hot water, HVAC and process pipework in a continuous closed-cell layer of insulation, supplied half-open with a lap for fast snap-on fitting.

The rigid foam core has a thermal conductivity of about 0.024 W/(m·K) (PUR) or lower, so a relatively thin shell achieves a high thermal resistance and keeps heat loss along the pipe to a minimum.

The closed-cell structure above 93% (PUR) / 95% (PIR) makes the shell waterproof and vapour tight, so it holds its performance on chilled and dual-temperature lines where condensation would otherwise soak a soft insulation.

A core density of 40–48 kg/m³ (commonly 45) gives a compressive strength at 10% deformation of at least 180 kPa, so the shell resists handling and normal pipe movement without crushing.

Standard pipe shells run from DN15 to DN600 with a wall thickness of 20–120 mm and a 1000 mm length; the half-open, lapped design closes tightly around the pipe and is sealed with a dedicated adhesive.

The longitudinal seam should be positioned away from the top of the pipe and the shell joints staggered along the run, with the gap filled by a special foaming sealant rather than ordinary glass glue.

For outdoor or wet service an outer cladding of galvanized steel or aluminum sheet protects the shell, and a continuous vapour barrier is essential so moisture never reaches the cold or hot face.

PUR shells suit hot water and HVAC duty from –50 °C to +100 °C; for deep cold lines a PIR grade extends service down to –196 °C with a higher B1 fire rating.

The shell must not be used above +120 °C for long periods, because at higher temperature the foam can age, shrink and powder over time.

Product Features

Pre-Insulated Pipe Shell – Half-open lapped section from DN15 to DN600 for quick fitting.
