Ring Stiffness, Ring Compression Bending and Initial Ring Stiffness

This testing machine is mainly used for determining the ring stiffness of plastic pipes with an annular cross-section and an inner diameter ranging from 600 mm to 2000 mm. Equipped with an inner diameter measuring device, it fully meets the ring stiffness measurement requirements for solid-wall pipes and corrugated pipes. Additionally, by adopting different fixtures, it can also perform mechanical property tests such as tension, compression, and bending on metal and non-metallic materials.

Ring Compression Bending Test

Ring compression bending describes a pipe's ability to resist deformation without structural damage. The same test setup as that used for ring stiffness measurement is adopted.
