Strength / Pressure Derating Factors Increased Operating Temperatures - Thermoplastic Piping

Increased temperatures derates the strength of thermoplastic piping materials. The chart below from (engineeringtoolbox.com) provides the derating factors for a number of Thermoplastic Pipes.

• PVDF - Polyvinylidene Fluoride
• CPVC - Chlorinated Polyvinyl Chloride
• PVC - Polyvinyl Chloride
• PB - Polybutylene
• PEX – Cross Linked Polyethylene
• PE – Polyethylene
