Cork gaskets, seals, Hsia electronic

 Installation requires a gasket, gasket and flange sealing surface should be clean, without any impact on the performance of the joint sealing scratches, spots and other defects. 2, the outer diameter of the gasket should be smaller than the outer flange sealing surface, the inner diameter of the gasket should be slightly larger than the inner diameter of the pipe gasket, the inner diameter difference between the two generally take two times the thickness of the gasket, to ensure that after compression gasket NBR sheet, without extending into the inner edge of the sealing gasket inside the container or conduit, so as not to interfere with the container or conduit in fluid flow. 3, gasket preload should not exceed the design requirements, in order to avoid excessive compression gasket lose resilience. 4, when the gasket compression, preferably using a torque wrench. High temperature and high strength bolts for large bolt gasket, it is best to use a hydraulic tensioner. Tightening torque should be based on a given compression gasket by calculation, the oil pressure of the hydraulic tensioner size should be determined by calculation. 5. When installing the gasket, the order should tighten the nut. But one should not twist design value is reached. Usually at least 2 to 3 times the cycle, so that the sealing gasket stress distribution. Gasket surface is not level, can be coated with sealant before installation gasket sealing surface. Sealants are generally made of manganese dioxide, lead, linseed oil (drying) the composition after graphite and survive. Can choose the appropriate type and brand of liquid sealant in accordance with the sealing medium, medium temperature and pressure conditions. 5, for installation octagonal metal ring gasket, when the metal ring gasket and flange seal groove machining is not ideal, it can be achieved with research by tight fit. For large-diameter metal ring gasket, with research more difficult cork gasket, in order to fill the tiny metal surface uneven, use sealant. 6, pressure vessels and piping flammable, explosive media facelift gasket security tools should be used, so as to avoid the tool flange or bolts collide, sparks, causing a fire or explosion. 7, if the pipeline leak, must buck treatment after installation gasket replacement or adjustment, non-pressure operation.
