Corzan® CPVC Pipe Pressure Ratings

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
 
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.
 

Corzan® CPVC Piping Pressure Ratings

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

Whitepaper: How CPVC Pipe Pressure Ratings Are Calculated

Learn the specifics behind how pressure ratings are determined for Corzan CPVC thermoplastic piping material and for the pipe itself.

CPVC Pipe Pressure Rating: How Is It Determined?

One of the most misunderstood aspects of CPVC pipe is how its pressure rating is calculated and what that rating really communicates to the end user.

Material Tests

Corzan® CPVC is rigorously tested to beat industry requirements for resistance to flame and smoke, bursting, flattening and impacts.
