Product Description

Cold Thermal Insulation Polyisocyanurate Rigid Foam Pipe with High Compressive Strength

Product Description

PIR foam pipe insulation provides efficient thermal protection for pipelines and equipment operating between -196℃ to +150℃. It delivers optimal insulation performance for cryogenic applications including Liquefied Nitrogen (LN2, -196℃), Liquefied Natural Gas (LNG, -162℃), and Liquefied Ethylene (LEG, -104℃).

Key Features

Fire resistance rated B1
Operating temperature range: -196℃ to +120℃
Excellent dimensional stability
Customizable cutting in panels and pipes to meet specific requirements

Applications

This PIR foam is an ideal organic low-temperature insulation material featuring minimal thermal conductivity and superior dimensional stability. Suitable for a broad temperature range, it's extensively used in LNG, ethylene, cold storage, and other cryogenic industrial applications.

Typical PIR Insulation System Structure

PIR Shell: inner layer + middle layer (if required) + outer layer
Secondary Vapor Barrier: PAP aluminum foil
Main Vapor Barrier: mastic + fiberglass meshes + mastic
Metal Protective Layer: aluminum alloy plate, stainless steel plate, aluminized steel plate, GRP
Sealant: HS-10-02, Foster 95-50, etc.
Strapping Material: stainless steel tape, sub sensitive tape

Packing and Storage

Store in dry, lightproof, shaded, and ventilated areas away from heat sources and direct sunlight
Inner packaging consists of black polyethylene bags with outer carton packaging

Handling Instructions

Handle PIR gently, avoiding rolling, collisions, and heavy pressure during transport
When installing on pipes and equipment, secure with glass fiber tape or steel bands
Use saws for cutting during application
