Ring Stiffness Tester – QualiRST™ Series
Ring Stiffness Tester – QualiRST™ Series is designed to measure the ring stiffness of thermoplastic pipes with a circular cross-section. It also supports flat testing and ring flexibility testing. It meets testing standards for PE double-wall corrugated pipes, winding pipes, and various plastic pipes. Additionally, it features an extended creep ratio test function, allowing for the evaluation of large-diameter buried plastic pipes by simulating long-term stiffness reduction under deep burial conditions. This series has received CE certification for compliance with EU product standards.
