Spiral Wound Gasket

Features

Spiral Wound Gasket is the ideal gasket in the semimetallic category. A narrow strip of V-shape metal hoop is spirally wound under tension sith 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 provieds gasket excellent characteristics.

• Resistance to high temperatures and high pressures.
• Great resilience which allows the gasket to adjust automatically to  changes 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 non-circular shape.
• Available in a variety of hoop metals and filler materials to satisfy specific operating conditions.
