PRESSURE RATINGS

Industrial pipe and fittings respond differently to internal pressures. The Corzan® CPVC compound has been pressure rated in accordance with ASTM D2837 and PPI TR-3 having Hydrostatic Design Basis (HDB) of:

  • 4000 psi at 72°F (23°C) as listed in PPI TR-4
  • 1000 psi at 180°F (82.2°C) as listed in PPI TR-4

Corzan CPVC with pressure rating

When compared to generic CPVC materials, fittings made from Corzan CPVC demonstrated improved creep resistance, and the ability to better withstand long-term, high-temperature hydrostatic pressure. These fittings lasted four times longer than those molded with other CPVC compounds when pressure tested at 180°F (82.2°C) at 551 psi.

 

Learn about how CPVC pipe pressure ratings are calculated in our resource article, "How CPVC Pipe Pressure Ratings Are Calculated."

 

Corzan® CPVC Piping Pressure Ratings

Corzan system pressure ratings are a function of pipe compound, pipe schedule, pipe size and operating temperatures. Corzan internal pressure ratings for CPVC 4120-05 schedule 80 and 40 pipe are listed below, as are collapse pressure ratings.
