How to measure the ring stiffness. You can use Hebei
Ring stiffness testing machine to test. And can test the tensile strength, bending strength, bending modulus, shear strength, ring stiffness and other tests.
Plastic pipe is a high-tech composite building chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging after steel, wood and cement. In recent years, chemical building materials have made rapid progress in our country. In particular, the widespread use of new environmentally-friendly plastic pipe has created a revolution in replacing traditional building materials.
The numerical value of the stiffness of the plastic pipe ring represents the resistance of the plastic buried pipe against external pressure. If the ring stiffness of the pipe is too small, the pipe may undergo excessive deformation or collapse. On the other hand, if the ring stiffness is chosen too high, excessive moments of inertia in the area must be used, which will cause too much material and cost.
Testing range: testing of ring pipe flexibility, ring stiffness, flatness, weld elongation, pipe creep ratio, etc., determination of ring stiffness of ring-shaped cross-section thermoplastic plastic pipe and glass-fiber reinforced plastic pipe, meeting PE double-wall corrugated pipe, winding pipe And various pipe standards requirements.
