Product Description

Polyurethane Foam Pipe Shell Cryogenic LNG Pipeline Insulation Low Thermal Conductivity for Gas Line

Product Description

Polyurethane Foam Pipe Shell for cryogenic service is a rigid insulation section made from PUR and PIR closed-cell foam, engineered for LNG and deep-cold pipelines where very low temperature and moisture control are both critical.

The PIR grade keeps a thermal conductivity near 0.022 W/(m·K) at 25°C and about 0.017–0.019 W/(m·K) at –100°C (PUR about 0.024 W/(m·K)), sharply limiting heat gain into deep-cold lines.

With a closed-cell content above 93% (PUR) to 95% (PIR), water absorption at or below 4% and very low vapour permeability, the shell resists the moisture ingress that would otherwise destroy insulation value.

Two half-shells with a lap joint wrap around pipes, elbows and valves, and staggered joints keep the vapour path closed along the line.

PIR stays dimensionally stable at –50°C within 1.0% and tolerates the expansion joints that accommodate the larger cold contraction of deep-cold systems.

Typical applications include LNG transfer lines, cryogenic pipelines, liquefied gas terminals and low-temperature petrochemical networks from –50°C (PUR) down to –196°C (PIR).

Product Features

Cryogenic High-Temperature Resistant – PIR stable to –196°C; PUR covers –50°C to +100°C service.

Low Thermal Conductivity – 0.022 W/(m·K) (PIR) limits heat gain into cold lines.

Closed-Cell Waterproof – Above 93% (PUR) to 95% (PIR) closed cells block moisture.

Two-Half Lap Joint – Half-shells with staggered lap joints keep the vapour path closed.

Dimensional Stability – Shrinkage at –50°C within 1.0% with expansion joints.
