Phenolic Insulation Pipe Shell for Liquid Ammonia Tanks

Engineered specifically for liquid ammonia storage and transportation systems, our phenolic insulation pipe shell delivers superior thermal protection in extreme low-temperature environments. This high-performance solution combines exceptional insulation properties with chemical resistance to safely maintain pipeline temperatures in ammonia refrigeration and industrial processing applications.

Critical Performance Features

1. Ultra-Low Temperature Performance

Maintains thermal conductivity of 0.021 W/m·K at cryogenic temperatures

Effective operating range: -50°C to +80°C

Prevents frost formation and temperature fluctuations

2. Ammonia-Compatible Construction

Chemically resistant phenolic formulation withstands ammonia exposure

Non-absorbent closed-cell structure prevents moisture retention

Eliminates corrosion under insulation (CUI) in humid environments

3. Safety-Enhanced Design

Class A fire rated with flame spread index <25

Self-extinguishing properties for industrial safety

Low smoke emission during combustion events
