It was set up in as the direct marketing side of our automotive manufacturing company, which itself has over 25 years experience in the trade. You will find all our staff friendly and helpful and will do our very best to provide any help or additional information you may require. Although the majority of the business that our manufacturing company carries out is now on the agricultural side, it still has the capability to provide most automotive gaskets. We have developed our own range of High Performance Cosworth Gasketswhich we are very proud of.
It applies mainly to all types of circular gasket products and facings typically used in process or power plant pressure vessels, heat exchangers and piping including solid metal, jacketed, spiral wound and sheet type gaskets. As an option, the maximum assembly stress for those gaskets is also determined by this procedure.
It indicates the initial gasket stress required to seat the gasket with tightness.
It indicates the capacity of the gasket to ensure tightness. It indicates the capacity of the gasket to maintain tightness when pressure is applied, as well as the gasket's sensitivity to unloading. Tp The Tightness Parameter is dimensionless. Tpmax The maximum tightness obtained when loading the gasket.
Tpmin The minimum tightness obtained when unloading the gasket. A series of 3 loadings and unloading cycles is applied during which leak rate is measured at each stress level.
Depending on the step, the system is pressurized to either The holding time at each step is dependent on when a leak rate stabilizes, with a minimum hold time of 1 minute and a maximum hold time of 5 hours.
The data collected is grouped into two Parts, Part A and Part B, and analyzed to generate the test parameters. Part A represents the initial seating performance of a gasket during initial flange tightening.
Data from Part A is used to determine Gb, "a", and Tpmax. Part B simulates actual operating conditions. Data from Part B is used to determine Gs and Tpmin. Loading cycles, with gradually increasing compression stresses, are applied on the gasket during which leak rate is measured at each stress level.
The system is pressurized to The holding time shall not exceed 15 minutes at each stress level.
The test is complete when the leak rate at a stress level exceeds the leak rate observed at S1 level or when the maximum load of the equipment is reached.
Maximum Allowable Stress is the maximum stress level where S1 leak rates were maintained.GORE GR Sheet Gasketing is designed to outperform both conventional (filled and skived) PTFE and other ePTFE gasketing in steel piping and equipment. Gaskets are used in many mechanical devices to seal joints between metal surfaces to prevent leaking of fluids or air.
Custom gaskets for new products and projects are easy to make at eMachineShop using silicone rubber, neoprene rubber, nitrile rubber, gasket paper, cork, fiberglass or plastic.
