TYPE OF SPIRAL WOUND GASKET:

spiral wound gasekest,have 4 types:

SW - Basic Type   

SWI - Inner Ring Type

SWC - Outer Ring Type

SWCI - Inner & Outer Rings Type

Structure :

1.Metal strip: the processed metal strip has good elasticity and recovery. It provides the filler enough tensile strength.

2.Filler: this part is the main body of the gasket and different material is used in different conditions

3.Centering ring:the centering ring does not come into direct contact with contained fluid. It is normally made of carbon steel and electro plate or painted to avoid corrosion. Other materials are available on request.

4.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 strip.
