    Spiral Wound Gaskets
    Spiral Wound Gaskets can be used to seal fluid pressure up to 250 bar cryoprnices temperature as low as -200¡ãC and up to elevated temperature of 1000¡ãC. Spiral Wound Gaskets are widely used in the oil, gas, petrochemical process and engineering industries.The spiral wound gaskets is made up of winding material body and inner/outer ring.There are spiral wound gaskets with ss304/ss304L tape+graphite/asbestos/PTFE tape,spiral wound gaskets made of ss316/ss316L tape+graphite/asbestos/PTFE tape,spiral wound gaskets made of ss321 tape+grphite/asbestos/PTFE tape,spiral wound gaskets made of other metallic tape+asbestos/graphite/PTFE tape,spiral wound gaskets winding body with ss304/ss304L/ss316/ss316L/carbon steel inner ring,spiral wound gaskets winding body with ss304/ss304L/ss316/ss316L/carbon steel outer ring,spiral wound gaskets winding body with both ss304/ss304L/ss316/ss316L/carbon steel inner ring and ss304/ss304L/ss316/ss316L/carbon steel outer ring.
    EXPANDED GRAPHITE CUT GASKET
    Expanded graphite cut gasket are punched or cut from pure expanded graphite sheet or reinforced expanded graphite sheet. Expanded graphite cut gasket has excellent corrosion resistance, high and low temperature resistance.expanded graphite cut gasket has good compression resilient and high intensity. Expanded graphite reinforced sheet can be cut into all kinds of circular, complicated geometric expanded graphite cut gasket. Expanded graphite cut gasket are widely used in pipe, valve, pump, pressure vessel, thermal exchanger, condenser, engine, air compressor, exhaust tube, refrigerating machine, etc.There are many kinds of expanded graphite cut gasket,such as expanded graphite cut gasket with ss304 insert,expanded graphite cut gasket with ss304L insert,expanded graphite cut gasket with ss316 insert,expanded graphite cut gasket with 316L insert,expanded graphite cut gasket with tinplate insert,expanded graphite cut gasket with other insert.
    PTFE gasket is made by cutting PTFE stick, pipe and sheet into flat shape PTFE gasket, v shape PTFE gasket or valve annulus PTFE gasket.PTFE gasket has 100% PTFE structure. PTFE gasket can bear the most bitter chemical medium, and PTFE gasket has good anti-creeping performance.PTFE gasket is a replacement of asbestos. PTFE gasket is anti-creeping, anti-cold-flow, anti-low-temerature. PTFE gasket has no pollution. PTFE gasket is easy to install and replace. under small pre-stress force, PTFE gasket can bear great internal pressure even in a environment of changing pressure. PTFE gasket is the best suit the condition with rough and fragile flange and alternately-changing temperature.
    PTFE envelope gasket are use for type of static seal. PTFE envelope gasket is composed of elastic materials. such as PTFE envelope gasket composed of compressed non-asbestos sheet and a PTFE envelope cove,PTFE envelope gasket composed of rubber and a PTFE envelope cove,PTFE envelope gasket composed of Ceramics and a PTFE envelope cove,etc.PTFE envelope gasket has superior properties against chemical (not affected by all chemicals except molten alkali metal and fluorine at elevated temperature).PTFE envelope gasket has a wide working temperature range. (180-260¡æ).PTFE envelope gasket has low coefficient of static and dynamic friction. PTFE envelope gasket is the best of the ¡°non-stick¡± materials. PTFE envelope gasket has excellent weathering and aging characteristics.PTFE envelope gasket is used to seal pipe flanges glass lined, PVC or FRP.PTFE envelope gasket has low bolt torque effecting a seal and chemical compatibility.
    Asbestos gasket can be used for most medium specification applications.Asbestos gasket for medium pressures:asbestos gasket can be used for sealing against steam,air, gases, water, oils, hydraulics and non-aggressive media. Asbestos gasket can also be used for high pressures.Asbestos gasket is used for sealing against steam, air, gases, water, oils, hydraulics and non aggressive media. Asbestos gasket for high temperature/pressures,too. Asbestos gasket is used for sealing against steam, air, gases, water, oils, hydraulics and non aggressive media.
    Non-asbestos Gasket is a sealing material made by adding special adhesives and a little packing into it, then roll and sulfurated .Non-asbestos Gasket is a replacement of asbestos gasket. Non-asbestos Gasket has better strength, elasticity.Non-asbestos Gasket has supper strong anti-penetrate performance. Non-asbestos Gasket is a better choice than asbestos gasket in high temperature and high pressure condition. And Non-asbestos Gasket is product using material with environment protection.
    Rubber gasket is cut from NBR,SBR,CR,EPDM.Some rubber gasket have resisttance of oil,Some rubber gasket is used in cold fever,Some rubber gasket has anti-aging properties.There are various shapes of rubber gaske.Rubber gaskets are widely used in medicine, electronics, Chemical, anti-static, fire-retardant, food and other industries. Other rubber gaskets: neoprene rubber gaskets, natural rubber gaskets, EPDM rubber gaskets, acrylic plastic rubber gaskets and other special rubber gaskets.
    Ring joint gaskets are made by forging and heat treatment.Ring joint gaskets are used in oil and the flange, pressure vessels, high-speed joint face, such as high temperature and high pressure valve cover gasket sealed metal.In particular pressure, temperature fluctuations Of the occasion,Ring joint gaskets can still maintain good seal.
    R-type over ring joint gaskets are commonly divided into an oval or octagona type.R-ring gaskets are manufactured as API 6A and ASME B16.20-standard. The maximum pressure of Ring joint gaskets is up to 10000 PSI.In the flange of trapezoidal slot, octagona ring joint gaskets and ring joint gaskets are interchangeable. RX-type ring joint gaskets are applied to enhance the capability of R-ring gasket. BX-type ring joint gaskets are applied to 15000 PSI pressure system. There are many materials and apply to different forms of design and operational requirements, reference material characteristics table.
    Note: The material should be 15 ~ 20 HB lower than the hardness of flange surface.
