Overview

Compares the mechanical properties of CPVC and PPR pipes under hydrothermal aging, indicating potential service life insights.

Key Points

  • The central aim is to explore how hydrothermal aging affects the mechanical properties of CPVC and PPR piping materials.
  • Conducted aging tests at temperatures of 23, 69, and 90 °C over 90 days.
  • Performed tensile tests to measure strength and elongation changes.
  • Applied a static damage model for lifetime prediction under hydrothermal conditions.
  • PPR tensile strength decreased from 40 to 28 MPa, while CPVC's declined from 75 to 52 MPa.
  • Both materials experienced a reduction in elongation at break with increasing temperature.
  • Findings suggest that CPVC performs better than PPR in hydrothermal aging.
