Non-metallic flat gasket
EXPANDED GRAPHITE CUT GASKET
Expanded graphite cut gasket are punched or cut from pure expanded graphite sheet and reinforced expanded graphite sheet. Depend on its excellent corrosion resistance, high and low temperature resistance, good compression resilient and high intensity. All kinds of circular, complicated geometric gasket are widely used in pipe, valve, pump, pressure vessel, thermal exchanger, condenser, engine, air compressor, exhaust tube, refrigerating machine, etc.
PTFE GASKETS
PTFE gasket is made by cutting PTFE stick, pipe and sheet into flat shape, v shape gasket or valve annulus. It has 100% PTFE structure. It can bear the bitterest chemical medium, and has good anti-creeping performance.
Expanded PTFE gasket is a replacement of asbestos. It is anti-creeping, anti-cold-flow; anti-low-temperature. It has no pollution. It is easy to install and replace. Under small pre-stress force, it can bear great internal pressure even in a environment of changing pressure. It is the best suit the condition with rough and fragile flange and alternately-changing temperature.
PTFE ENVELOPEN GASKET
PTFE envelope gasket are type of static seal. It is composed of elastic materials such as compressed non-asbestos sheet ,rubber, Ceramics, etc., and a PTFE envelope cove
PTFE has superior properties against chemical (not affected by all chemicals except molten alkali metal and fluorine at elevated temperature) and a wide working temperature range. (from-180~260C) the coefficient of static and dynamic friction of PTFE is very low. PTFE is the best of the "non-stick" materials. It has excellent weathering and aging characteristics.
Application: PTFE envelope gasket is used to seal pipe flanges glass lined, PVC or FRP. Low bolt torque effecting a seal and chemical compatibility is a main characteristic of this type of gasket.
ASBESTOS GASKETS
Asbestos gasket for low pressure, Manufactured from long fiber white chrysotile asbestos. It has been designed to meet most low temperature and low pressure requirement. It is suitable for sealing against steam, gas, gases, hydraulics, oil and non-aggressive media.
Asbestos gasket for medium pressures, it can be used for most medium.
Applications: used for sealing against steam, air, gases, water, oils, hydraulics and non aggressive media.
Asbestos gasket for high pressures, it can be used for most medium
Applications: used for sealing against steam, air, gases, water, oils, hydraulics and non aggressive media.
Asbestos gasket for high temperature/pressures: used for sealing against steam, air, gases, water, oils, hydraulics and non aggressive media.
NON-ASBESTOS GASKETS
Non-asbestos Gasket is a sealing material made by adding organic fiber such as aramid and NBR rubber and so on. As containing asbestos fibers rarely, it is a replacement of asbestos gasket. Non-asbestos Gasket has better strength, elasticity and supper strong anti-penetrate performance. It is a better choice than asbestos gasket in high temperature and high pressure condition. And it is product using material with environment protection.
