Spiral wound gasket is formed of V-shaped of W-shape stainless steel stripe and soft nonmetallic packing or the material of flexible graphite asbestos, nonasbestos, PTFE etc by means of piled. It can use inner ring and outer ring as different material such as carbon steel, stainless steel 304, 316, 316L and etc. The static sealing element of pipe, valve, pump, thermal exchange, condensing motorcycle, auto vent-pipe, tower, plain hole and hole of flange, etc.

Metal - jacketed gaskets are particularly suitable for sealing flat surfaces of heat exchangers, gas pipes, cast iron flanges, autoclaves and similar. By their sealing efficiency, provided by exerting strong pressure on circular rims of the flanges, metal - jacketed gaskets can stand up to 30% deviation from the initial thickness, which is very useful in case of irregular or faulty flange rims. The chemical compatibility of the metal and the medium being sealed should be considered.

.

The most basic form of jacketed gasket, with coverage on one face and both edges

.

Where full coverage is needed and flange is narrow relative to gasket ID.

.

Stronger and more rigid than double jacket gasket.

.

Corrugations create a labyrinth seal across the gasket face.

.

 Provides coverage on one side only (inside or outside) and both faces. Flange is narrow relative to gasket ID

.

Kammprofile is a composite gasket, which utilises a serrated metal core with a soft facing material. 
The metal core is a machined on each contact face with concentric serrations which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the flange even at relatively low bolt loads. The result is a gasket, which combines the benefits of soft, cut materials with the advantages of seal integrity associated with metallic gaskets. Expanded graphite is the most common facing material used for Maxiprofile gaskets. However, other materials can be used, such as PTFE for chemically aggressive duties or mica for high temperature duties.
