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
