Spiral Wound Gasket manufactured by Wealson is widely in demand for features like increased resilience and ability to withstand high temperatures and pressures. This is mainly used in valves and oil refineries. It can be manufactured with any material as per customers requirement in accordance with the standard ASME, DIN, BS, API or to customer's specification.
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/steal. 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.
