SRI
Leader Style SRI SWG’s are provided with an inner and outer ring. These gaskets are suitable for ASME B16.5 raised faced flanges up to 2500 lbs and for EN/DIN flanges up to PN400. Spiral Wound Gaskets "SRI" can be used in a wide variety of media, temperature depends on used materials; standard SS316L - 100 °C up to 550 °C.
Low Stress / Low Density / High Density
All spiral wound gaskets can be produced with a Low-Stress winding. In this winding we use a slightly wider filler material than standard. This makes it possible to have a good seal where only a low surface pressure is available. Only for low pressure applications.
Another option is a low density winding or high density winding. This makes deformation under load easier, or harder, assuring a tight seal in your custom application.
