摘　　要：介绍了带加强圈的聚四氟乙烯膨胀节及带加强圈且外包不锈钢丝网的聚四氟乙烯膨胀节在爆破压力下波纹鼓胀破裂的试验以及给出的爆破压力计算式。在较高压力下的不锈钢膨胀节波纹也会产生凸鼓变形，直至纵向破裂，也给出了该最大爆破压力的计算式。Abstract The rupture experimient of a reinforced polyflon bellows wrapped closely with stainless steel wire net or without stainless wire net subject to internal pressure and the calculation formula of this rupture pressure are introduced, in this paper. A stainless steel bellows which is imposed by increased internal pressure bulges firstly and ruptures longitudinally in the end, the maximum calculation rupture pressure formulae in this situation is also given.
