The ring stiffness is a performance parameter of the pipe capable of resisting external pressure load, and in order to ensure safe operation of the pipe under the external pressure load, the selection of the ring stiffness is one of the key factors in design. If the ring stiffness of the pipe is too small, the pipe may be excessively deformed or buckling instability is damaged in the use process; conversely, if the ring stiffness is selected too high, too large a cross-sectional moment of inertia will be used, which will result in too much material and too high cost, and therefore, whether the ring stiffness of the tubing is suitable has a critical impact on its specific application design.
When the pipe is subjected to ring stiffness test, a tester generally places a sample at the stress center of the test bed for testing by virtue of working experience. The tubular product detects and can burst apart when being pressed, and the piece that bursts apart pops out fast, has the potential safety hazard that hurts staff around, in addition, because of being limited by the vertical guide rail interval in test machine both sides, the great sample of pipe diameter size needs to rotate tubular product axial 90 degrees when the test, also can produce inconvenient pair pivoted problem.
