Function :
The electronic ring stiffness testing machine adopts electric loading, electronic measurement, continuously adjustable speed, and real-time control by microcomputer. The machine simultaneously displays the test force, displacement, test speed, and test state, and has functions such as test force peak hold, displacement peak hold, and automatic return. This machine is widely used in the ring stiffness and mechanical properties test of PE/PVC/winding corrugated pipes, plastic pipes, glass steel pipes, sand-filled glass steel pipes, and steel tape winding pipes.
