Product Description

 

Spiral Wound Gaskets with Inner Ring

Spiral Wound Gaskets with inner Ring is consisted of a spiral wound sealing component with a solid metal inner ring. Inward buckling of spiral-wound gaskets has been identified as a potential problem. Inner rings shall be furnished with all spiral-wound gaskets having PTFE filler material. Inner rings for flexible graphite-filled, spiral-wound gaskets shall be furnished unless the purchaser specifies otherwise. For all filler materials, inner rings shall be furnished in spiral-wound gaskets for

(a) NPS 24 and larger in Class 900

(b) NPS 12 and larger in Class 1500

(c) NPS 4 and larger in Class 2500

Inner rings are required for these gaskets due to high available bolt loads, which may result in outer ring damage. Suitable for male and female pipe flanges.

Strength of Spiral Wound Gasket

 

> Spiral Wound Gasket is the ideal gasket in the semi-metallic category. A narrow strip of V-shape metal hoop is spirally wound under tension with a filler cushion between the lamination of the metal and is spot-welded at both ends.

> This unique construction of a spring-like metal and soft filler provides gasket excel-lent characteristics.

 

> Resistance to high temperature and high pressures.

 

> Excellent sealability is maintained with comparatively small gasket area.

> Great resilience which allows the gasket to adjust automatically to change in operating conditions, such as pressure and thermal shocks, vibrations etc.
