Ginseal Spiral-wound gaskets comprise a mix of metallic and filler ma- terial. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flex- ible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.

2.Features of Gasket :
• Wide range of applicable working condition,high temperature and high pressure resistance,applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium,through change of composition of gasket.
• Strong stress compensation,stable and reliable sealing performance even under frequent pressure fluctuation condition.
• Perfect sealing performance.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.
• Heat treatment industry for furnace parts, fans, tube hangers, and baskets and trays to hold small parts.
• Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide.

4.Specifications of the Gasket:
1.A good compression ratio and elasticity.
2.With plastic appropriate, after pressing can adapt to the sealing surface and sealing surface uneven fill the gap, to ensure good sealing performance with the temperature and pressure in the system of alternating case.
3.With excellent corrosion resistance, not to be damaged in some extreme medium, does not have the expansion and contraction.
4.Under the condition of high temperature softening, does not creep; under the condition of low temperature hardening, does not shrink.
5.Have sufficient strength, when external load conditions, not be crushed; at high temperature, not blown out.
