根据垫片材料的多次重复试验得出合理的试验数据。试验包括热诱导蠕变的计算,常规的质量和能量变化的分析,在内压为4MPa,温度上升至400℃时的密封性,升温后在螺栓紧固法兰状态下的长期密封性等,为控制试验参数,采用金属构件且能以一个有效的方式正确地显示出试验结果;用改变试验温度、内外压力和环境状态的方法来评价材料,填充材料和复合垫片板材的结构特性。
According to gasket material repeated test to obtain reasonable test data. The tests include the calculation of heat-induced creep, conventional analysis of mass and energy changes, sealing at internal pressures of 4 MPa, temperatures up to 400 ° C, long-term sealing under bolt-on flange conditions after warming, In order to control the test parameters, the metal components are used and the test results can be correctly displayed in an effective way. Structural properties of the material, the filler material and the composite gasket sheet are evaluated by changing the test temperature, internal and external pressures and environmental conditions.
