Product Description
| Spiral Wound Gasket is the ideal gasket in the semi-metallic category. A narrow strip of V-shap 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 excellent characteristics: ※ Resistance to high temperature and high pressures. ※ Great resilience which allows the gasket to adjust automatically to change in operating conditions, such as pressure and thermal shocks, vibrations etc. ※ Excellent sealability is maintained with comparatively small gasket area. ※ Good tolerance for flange surface finish irregularities. ※ Can be designed to any dimensions economically in circular or moderately noncircular shape. Available in a variety of hoop metals and filler materials to satisfy specific operating conditions. |
