Effect of Angle of V-Type Steel Belt on Performance of Spiral Wound Gasket

Article Preview

Abstract:

The performance of spiral wound gasket with different angle of V-type steel belt is researched, which includes effect of angle of V-type steel belt and pressure on compression rate and rebound rate. The results indicate that, when the pressure is same, the compression rate of spiral wound gasket decreases and rebound rate of spiral wound gasket increases with the angle of V-type steel belt increasing. When the angle of V-type steel belt is different, the optimum preloading need adjust in order to spiral wound gasket work well. For spiral wound gasket DN80, the optimum pre-pressure should be controlled within 45~55 MPa when angle of V-type steel belt is 80-degree, and the optimum pre-pressure should increase with angle of V-type steel belt increasing.
