Ring stiffness testing machineis mainly used for determination of the maximum stress value, upper and lower yield strength, compression, ring stiffness, ring flexibility, drawing pipe, pipe creep ratio series of experiments. Can be classified to microcomputer control ring stiffness testing machine and a liquid crystal display ring stiffness testing machine, the radius of the production models WDS-10H/20H/50H/100H/200H digital display (LCD) two kinds of ring stiffness testing machine, WDW-20H/50H/100H microcomputer control ring stiffness testing machine. The radius of the circle of the ring stiffness testing machine can be based on the special needs of the user to increase the tensile, compression, bending and other functional testing, is a multi-functional electronic universal testing machine.
