Piping’s pressure-bearing capabilities must satisfy the long-term demands of an industrial process. Piping used in industrial processing applications must stand up to both intense pressures and elevated temperatures without fail for extended periods of time—10 to 20+ years depending on the application. For this reason, piping material manufacturers are required to empirically prove their compound’s pressure-bearing capabilities.
Standard test methods developed by ASTM, ISO, and the Plastic Pipe Institute define pressure ratings for thermoplastic compounds (e.g., CPVC) to verify their long-term hydrostatic strength (LTHS). Specifiers can use these ratings to gauge how well the material will stand up under their own system’s conditions.
To help you understand these issues, Corzan Industrial Systems’ product and engineering team has written a free white paper, How CPVC Pipe Pressure Ratings Are Calculated, which provides a deep dive into the ASTM method for determining pressure ratings. It walks you through the specifics behind how pressure ratings are determined for Corzan thermoplastic piping material and for the pipe itself and advise on what needs to be accounted for when designing an industrial piping system.
Specifically, this white paper covers:
- How LTHS is determined at various temperatures and stress levels
- How the data is validated up to the 100,000-hour mark
- What to account for when designing an industrial piping system
