The use of pipe flange connections is standardized in the codes of JIS, ASME, DIN and so on. However, these codes are almost entirely dependent on experience, and subsequently some problems concerning pipe flange connections have been encountered. In the present paper, the distribution of contact stresses which governs the sealing performance is analyzed as a three-body contact problem, using a...
An anvil-preformed gasket system has been developed to extend the pressure range for the widely used large volume cubic press without sacrificing the sample volume. The relationship of the sample chamber pressure versus press load for this system was calibrated at room temperature using transitions in Bi, Tl, and Ba. With similar sample volumes (8-11 mm in diameter and 8 mm in length), the anvi...
In the natural gas gathering and transportation station, bolt-gasket-flange connection (BGFC) is main mode, but due to its large number, micro-leakage may result in serious consequences. For this reason, early BGFC evaluation can effectively assist decision-making prevent occurrence of accidents. To solve problem insufficient field data collection, we proposed a Noisy-OR gate based fuzzy fault ...
Increasing the power (torque) of nowadays engines, along with reduction of fuel consumption and dimensions of them, cause to the use of turbocharged systems. Since turbo chargers are exposed to the exhaust hot gases and have a high operating speed, it is necessary to utilize high technology design and special materials with high cost. The temperature of the exhaust system with gasoline fuel som...
During the servicing of flange fasteners, sealing gasket and cover interface are prone to separation air contamination due factors such as stress, corrosion, vibration. In detection process, there two main issues: firstly, conventional ultrasonic measurement methods based on theory acoustic elasticity not applicable small thickness layer; secondly, use vertical incidence is difficult ensure inf...
