ETM Series (50kN-100kN)
The ring stiffness testing machine is designed for determining the ring stiffness of large-diameter plastic pipes with a maximum test force of 50kN or 100kN. In addition to ring stiffness testing, the testing machine can also perform tensile, compression, and bending tests on various metal and non-metal materials.
Applications
- PVC Pipes: PVC-U (unplasticized rigid PVC), PVC-M (modified PVC)
- Polyolefin Pipes: HDPE pipes, PP pipes (PP-H, PP-B, PP-R)
- Corrugated Pipes: HDPE double-wall corrugated pipes, PP double-wall corrugated pipes (the most common application for ring stiffness testing)
- FRP/Composite Pipes: Glass fiber reinforced plastic pipes (GRP/FRP)
