Product Name:Ring-Stiffness Universal Testing Machine
Product Detailed:

This series of testing machine is mainly used to test the ring stiffness of all kinds of thermal-plastic and fiber-glass pipes. Complete with tensile test device and bending test device, it can also perform tensile test and bending test for metal, non-metal & compound materials. It is widely adopted by plastic pipes manufacturing industries, petrol-transportation field, water feeding and draining fields, scientific research institutes and universities. It is ideal equipment for quality control and supervision.
