Metallic strip	The standard thickness of the metallic strip is 0.2 mm.
Filler	Filler is normally used for thickness from  0.5 mm to 0.6 mm.
Centering ring	The centering ring does not come into direct contact with contained fluid. It is normally made of carbon steel and electro plated or painted to avoid corrosion. Other materials are available on request.
Inner ring	Inner ring is used to avoid excessive compression due to high seating stress in high-pressure service and it is also used to reduce turbulence in the flange area. It is normally made of the same material as the gasket metallic srtip.

 

Characteristics

A spiral wound gasket able to compress and seal under various loads and provide sealing capabilities. The gasket generally includes a spiral wound portion and an outer guide ring to limit the compression of the gasket. The spiral winding is formed of interdisposed windings of a metal and an elastomer sealant. The metal winding has a non-planar cross-section to inhibit buckling under compression. The gasket is dimensioned such that the elastomer sealant winding has a width greater than the width of the metal winding which has a width greater than the thickness of the guide ring. In this manner, the sealant is compressed before compression of the metal winding which can be compressed until the outer guide ring is encountered
