Product Description

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

Product Description

Pre-Insulated Polyurethane Foam Pipe Shell is a rigid PUR / PIR closed-cell two-half shell for insulating pipework, supplied with a lap joint so it snaps around the pipe and closes the insulation line quickly.

The shell delivers excellent thermal insulation with a thermal conductivity of 0.021–0.025 W/(m·K), cutting heat loss along long runs and keeping line temperatures at the design value.

A core density of 40–48 kg/m³ (PUR) to 48–60 kg/m³ (PIR) gives a compressive strength of at least 180 kPa (PUR) or 220 kPa (PIR), enough to resist the loads applied during handling and back-filling.

The closed-cell structure of 93% (PUR) to 95% (PIR) or more makes the shell closed-cell waterproof and vapor-tight, so moisture in the trench or soil cannot reach the pipe and degrade the insulation.

PUR shells suit general hot and cold service, while PIR shells add a B1 fire rating and a wider temperature range for higher-temperature or fire-sensitive lines.

The shell is a general-purpose pipe insulation rather than one fixed duty and is used on heating, hot and chilled water, HVAC, refrigeration and process pipework, and on tank or vessel nozzles.

Shells are installed with staggered, offset longitudinal joints seated away from the top of the pipe and sealed with a dedicated foam sealant; a protective jacket such as galvanized steel or aluminum is then fitted where needed.

Product Features

Excellent Thermal Insulation – Thermal conductivity 0.021–0.025 W/(m·K) cuts heat loss on long runs.

Closed-Cell Waterproof – Closed cells above 93% keep buried and outdoor pipework dry.

Fire Retardant B1 Grade – A B1 fire-rated PIR option is available for higher-temperature lines.

Snap-On Lap Joint – Two-half shell with a lap joint closes around the pipe fast.

PUR / PIR Available – PUR for general duty, PIR for higher fire and temperature service.
