Flexible Graphite ---Graphite Gasket

The gasket is punched or cut from pure expanded graphite sheet and AISI304, AISI316 reinforced expanded graphite sheets that have excellent corrosion resistance, high and low temperature resistance, good compression resilient and high intensity. All kinds of circular, all types of gaskets are widely used in pipes, valves, pumps, pressure vessels, heat exchangers, fluviographs, engines, exhaust tube, refrigerating machines, etc.

Typical Types/Properties
, Composite Graphite Gasket with Reinforcement
  It is formed by cutting or punching all kinds of reinforced graphite sheets. It is mainly used for
  sealing flanges, observation holes, covers, fluviographs, etc. They can be used at the position
  in corrosive media and high or low temperature media. It is a good substitute for asbestos
  rubber sheet.
   Specification: φ10-φ3,000mm; Working Temperature: -200 -650; Working Pressure+6.4Mpa
, Metal Jacketed Gasket
  The sealing material, such as, flexible graphite, asbestos and PTFE are covered within metal material
  of stainless steel, copper, carbon steel, etc.
  Typical Applications
   Suitable for sealing of pumps, valves, heat exchangers, etc. in various media and for sealing of
   all kinds of flanges.
   Working Temperature: -200-650; Working Pressure: 6.4MPa; Nominal Diameter: φ10-φ2,000mm
, Metal Toothed Gasket
  It is made of ordinary carbon steel, stainless steel AISI304, AISI316, and etc. through machining; it is
  mainly used for sealing of flanges of piping at high temperature sealing property and compressibility
  and recovery.
   Working Temperature: -200-650; Working Pressure: 25MPa; Nominal Diameter: φ10-φ2,000mm
, Spiral Wound Gasket
  It is formed by overlapping and winding stainless steel tape and flexible graphite tape, asbestos tape
  of PTFE tape, and then welding the end point. Except for manufacturing according to each kind
  of national standards, we can also manufacture as per your special requirements and the
  international standard, such as: ASME, ANSI, API, etc.
  Typical Applications
   It is mainly used for the sealing of piping, flanges, valves, exits and entrances of pumps, all kinds of
   heat exchangers, reactor towers, observation holes, hand holes and covers that contact with steam,
   oil gas, solvents, gas, heat-transfer media of high temperature and high pressure.
   Thickness 2.5, 3.2, 4.5mm, etc. nominal diameter: φ10-φ3, 000mm
  Typical Type
   Basic type, with inner ring, with outer ring, with inner and outer ring.
