Strength of Spiral Wound Gasket
> 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 lami nation 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.
> 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.
The Spiral Wound Gasket our factory manufacturing
> 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.

Thickness
The standard manufacturing thickness for spiral wound gaskets are: 3.2 mm; 4.5 mm; 6.5 mm (measured across metallic strip not including the filler, which protrudes slightly beyond the metal).
Manufacturing tolerances
The tolerance of the gasket diameters (d1, d2, d3, d4, s, s1) are stipulated by ASME B 16.20 and DIN 2632-2638 standards. The gaskets designed for non-standard flanges meet the recommendations by the ASME B 16.20.
Dimensions
The dimensions of the standard SWG meet the ASME, BS and EN (DIN) standards.
