Pipe ring stiffness testing machine

The ring stiffness testing machine is widely used to determine the ring stiffness of thermoplastic pipes and fiberglass pipes with annular cross-sections. The ring stiffness is determined by the measured force value and deformation value during constant speed deformation.It has key speed adjustment, digital display of test force displacement, and curve display functions. It has peak hold, automatic shutdown on damage, and automatic overcurrent and overload protection functions.It can complete pipe ring stiffness, ring flexibility, flatness, bending, weld tension and other tests.The ring stiffness testing machine has all the functions of an electronic universal testing machine and can be configured with tension, compression, bending, shear and other fixtures for tension, compression, bending, shear and other tests on various materials.
