摘要
分析了低压管法兰用缠绕式垫片的预紧应力,对通过垫片工艺结构的调整使其力学性能与紧固件的要求一致,从而使法兰接头符合操作的密封性要求进行了试验研究。
Analysis of pre-tightened stress has been made on pre-stress of low-pressure flange＇s spiral wound gasket, and through changing structure and controlling the manufacture process of gasket, some experiment studies have been made to let mechanical performance meet the needs of bolt load and let flange joint meet the needs of seal behavior.
