JJRST Ring Stiffness Tester

JJRST Ring Stiffness Tester
Model: JJRST
The JJRST series ring stiffness tester is suitable for the measurement of the ring stiffness of thermoplastic pipes with a circular cross-section, as well as for flat test and ring flexibility test. Meet the requirements of testing standards for PE double-wall corrugated pipes, winding pipes and various plastic pipes. In addition, it supports the extended creep ratio test function, which is used to measure large-diameter plastic buried pipes and simulate the decay of ring stiffness with time under long-term deep buried conditions. This series of ring stiffness testing machine has passed the CE certification of EU products.
