压力容器用大直径法兰连接密封垫片的选用

Selection of Connecting Sealing Gaskets for Large-diameter Flanges in Pressure Vessels

随着设备的大型化和操作参数的不断提升,法兰连接的密封问题越来越突出,适时化解已显得越来越重要。其中,正确选择大直径法兰用垫片是急需探讨的问题。根据大直径法兰连接结构的特点,结合不同垫片的特性,提出了大直径法兰垫片的选用建议,并结合工程实践,介绍了使用专利产品——双金属自密封复合垫片解决大直径法兰连接密封问题的案例。

With the larger size and higher parameter of equipment,sealing problems for flange connection have appeared more and more prominent,meanwhile solving these problems timely has also become more and more important.It is an urgent and worthy discussion about how to select gaskets properly for large-diameter flanges.According to the characteristics of large diameter flange connection,and combined with the characteristics of various gaskets,the gasket selecting suggestion for large-diameter flange was put forward.Besides,combined with the engineering practice,application examples were introduced where the connection sealing problems for large-diameter flange have been solved by adopting the latest patent products-double metal self sealing composite gasket.
