Fireproof and Corrosion-resistant Phenolic Pipe Shell for Chemical Pipelines

Engineered for aggressive chemical environments, our Fireproof & Corrosion-Resistant Phenolic Pipe Shell provides unmatched protection for industrial pipelines handling acids, alkalis, and solvents. Combining military-grade chemical resistance with Class A fireproof performance, this specialized insulation system ensures operational safety and energy efficiency in petrochemical plants, pharmaceutical facilities, and industrial processing units.

Core Performance Features

1. Extreme Chemical Resistance

Fully inert phenolic core resists:
• Concentrated acids (H2SO4, HCl, HNO3)
• Caustic solutions (NaOH, KOH)
• Organic solvents (acetone, ethanol)

Optional PTFE/FEP laminated facings for additional chemical barrier

2. Certified Fire Protection

Class A1 fire rating (EN 13501-1)

Zero flame spread with smoke density <5% (ASTM E662)

900°C integrity rating for 120+ minutes

3. Thermal & Mechanical Stability

0.023 W/m·K thermal conductivity maintained in chemical vapor environments

200kPa compressive strength withstands industrial impacts
