Product Description
The spiral wound gasket depends upon the mechanical characteristics of a formed metal spiral strip, rather than the compressive virtues of more traditional gasket materials. This makes it particularly suitable for low or fluctuating bolt loads. The sealing strips, or fillers, are usually graphite, although other materials such as PTFE may be used, the windings are always s/steel. For this type of gasket to work the spiral must not be over compressed, hence one of two types of compression control is usually used.
PTFE Spiral Wound Gaskets
SUNWELL SW600 spiral wound gasket is formed of V-shaped Metallic strip and hard and soft filler. Support rings, inside and Outside the spiral, improve the gasket's handing, fitting and Versatility.
Depend on its excellent compression resilience, it is suitable for sealing spots where the alteration of temperature and pressure are frequent.
PTFE Spiral Wound Gaskets Typical Applications
Pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc.
Petrochemical, chemical, mechanical manufacturer, power station, metallurgy, shipbuilding, medical and pharmaceutical unclear power station and navigation, etc.
