| 摘 要： | 结合法兰连接的实际,按照ASMEB16.20对缠绕式垫片压缩的要求,以HG标准中PN6.3MPa的管法兰为例,对缠绕式垫片的预紧应力进行了分析。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,使法兰接头符合操作时的密封性。结果表明,通过调整垫片结构,控制其制造工艺,可以达到调整垫片压缩回弹性能的目的,并可获得符合紧固件的要求和法兰接头密封性要求的产品。

| Abstract: | Combining with flange joints fact and the ASME B16.20 to spiral wound gasket request, such as PN 6.3 MPa pipe flange in HG standard, the seating stress of spiral wound gasket was analyzed. Through adjusting gasket structure, its mechanical performance is changed to consist with request of bolt, so that flange joints can meet the standard of sealing request. The result indicates that by adjusting to gasket structure and controlling fabrication process, flange joints can adjust gasket to reach intent of compressibility recovery. So we can achieve products that consist with demands of bolt and sealing performance of flange joints. |
