Product Overview

CPVC Thermoplastic Material Temperature Pressure De-rating
Elevated temperature  uid mediums require a de-rating of thermoplastic pipe maximum internal pressure ratings
at 73°F. To determine the maximum internal pressure rating at an elevated temperature, simply multiply the
product pressure rating at 73°F by the percentage speci ed for the desired temperature.
