Fastener gasket classification and characteristics

Fasteners in the use process, in order to make the mechanical seal between parts, we will use a gasket to seal, can also prevent between two objects under pressure, corrosion and pipeline natural heat bilges cold shrink and leakage. But in daily life, we often have the following types of sealing gasket, according to different types of its performance characteristics are different.
1, high pressure asbestos rubber sheet gasket
Asbestos rubber gasket asbestos fiber, rubber as the main raw material with rubber compounding agent and filler, made through the processes of mixing, molding, curing, hot roll. Asbestos rubber gasket according to the formula, process performance and use of different, can be divided into ordinary asbestos rubber gasket and oil resistant asbestos rubber gasket. According to the use of the temperature and pressure can be divided into low pressure asbestos rubber gasket, asbestos rubber gasket and high pressure asbestos rubber gasket. Sealing applicable to water, steam, oil, acid, alkali, solvent medium, asbestos gasket is mainly used in sealing flange connection, low in.
2, oil resisting asbestos rubber gasket
Characteristics: the oil resistant asbestos rubber gasket asbestos fibers by, oil resistant fibers, fillers, colorant and refined, widely used in petroleum, chemical industry pipeline and equipment, according to the working conditions, can choose the corresponding grade model.
Scope of application: oil resistant asbestos gasket: mainly used for steam, water, gas, oil and solvent and non corrosive medium seal.
3, cylinder gasket
Performance characteristics: cylinder gasket asbestos fibers by, oil resistant fibers, fillers, colorant and refined, is widely used in automobile. Motorcycle engine cylinder, according to the working conditions, can choose the corresponding grade model.
4, aramid gasket
Performance characteristics: Aramid gasket steam, organic solvent, acid, alkali, widely used for sealing the fluid conveying apparatus of pump, valves, pipes, containers etc..
Composition and characteristics: high strength, high wear quantity aramid fiber as the main materials and lubricants special material of the composite made of sealing products. This kind of seal products with wear resistance, excellent lubricity. Liquid phase mixing in the liquid, can display its prominent characteristics.
5, non asbestos gasket
The non asbestos gasket (non asbestos gasket) is based on aramid fiber, organic fiber and plant fiber and acrylonitrile butadiene rubber, inorganic mineral rolling sealing material formed at high temperature, due to asbestos containing very little fiber, suitable for non asbestos gasket substitute for asbestos gasket. The non asbestos gasket (non asbestos gasket) not only has high strength, but also has good resiliency, also has strong anti permeability performance is good environmental protection material instead of asbestos gasket under high temperature and high pressure.
6, asbestos pad
Asbestos cloth other auxiliary material molding, high temperature and high pressure used in corrosive seal. For the reactor, the reaction tank, manhole, hand hole and other parts. The use of temperature: -100 ℃ - +1000 ℃; working pressure: PN<5. 0Mp;
7, a rubber pad
A vinylidene fluoride and non fluoride, fluoride, propylene copolymer colloidal materials by elastic body, are widely used in military and civil industry, its characteristics are: high temperature resistance, ozone resistance, aging resistance, natural, vacuum resistance to fuel oil, lubricating oil resistance, strong anti oxidant, chemical resistance and good electrical insulation properties.
8, PTFE lining rubber pad
PTFE lining rubber gasket is tetrafluoroethylene clip package rubber gasket. Sealing resilience has strong corrosion resistance and high corrosion, suitable for enamel, glass pipe low pressure chemical equipment seal.
9, non asbestos gasket
Non asbestos gaskets according to the formula, process performance and use, can be divided into non asbestos rubber gasket and non asbestos gasket, they are based on aramid fiber, organic fiber and plant fiber, Dingqing rubber and minerals by rolling or copying process produced non asbestos gasket series, because asbestos free gasket series not only has high strength, but also has good resiliency, and has strong anti permeability performance, so they are the best environmental protection automobile and industrial machinery field replacement of asbestos gasket gasket.
