Challenges in bolted flange connection performance evaluation
Original language description
Bolted flange connections are probably the most important separable connections in pressure equipment. Their design is mostly driven by two requirements: strength and tightness. The strength is quite accurately covered by ASME, EN and other standards. Although tightness is also considered in some calculations, these are usually very simplified and discrepancies between design and actual performance can be expected. Connection tightness can be quantified by leak rate in milligrams per year and gasket diameter. According to leak rates, connections can be divided into several tightness classes. When designing bolted flange connection, tightness requirements are usually specified in terms of specific tightness class. In ideal case with uniform contact pressures, the leak rate of the connection depends on gasket contact pressure at the moment and the highest gasket contact pressure in the history. Other significant factors influencing the leak rate include type of fluid, fluid pressure and temperature, and
