Common causes of failure of Kammprofile Gaskets

　　The system safety protection measures are deliberately designed to fail during the abnormal period of the process. The next weak link in the system is the gasket. During the overpressure of the pipeline or pressure vessel, Kammprofile Gaskets usually burst first. Even if Kammprofile Gaskets have the correct specifications, these components can still fail for many reasons. Listed below are the most common causes of gasket failure.

　　Uneven compression: The uneven compression of Kammprofile Gaskets will produce low compression and high compression areas. The high compression area has higher burst resistance. The gaskets in the low compression area and the mating surface are less consistent, making them prone to leaks and bursts. When the surfaces are parallel to each other, Kammprofile Gaskets perform well. In flanges, parallel surfaces can be achieved by tightening the opposite bolts with equal turns until the gasket is compressed or using a torque wrench to ensure that all bolts apply equal force. For washers fastened by asymmetric bolts, please pay attention to the bolt arrangement. Areas with tighter bolts can produce higher compression.

　　Excessive compression: Excessive compression will cause the permanent failure of Kammprofile Gaskets. Signs of excessive compression are expansion or compression of the gasket material or inward buckling of the spiral wound gasket. Non-metallic gaskets are usually limited to 15,000 psi. Metal washers are designed to be crushed at higher pressures up to 30,000 psi.
