Applicable to the field of metal spiral wound gasket

There is a kind of sealing materialSpiral Wound Gaskets is called spiral wound gasket products, all kinds of valves, pumps, heat exchangers, tower classes and manholes, hand holes, etc. flange connection at best sealing elementswidely used in machinery manufacturing, shipbuilding, power industry, metallurgy and petroleum, chemical and other fields.

 The most prominent feature of the gasket is suitable for use in uneven load, under strong acid and alkali, temperature and pressure to produce a periodic change or impact or vibration operating environment. This gasket production process is more complex, it needs to use a band of high-quality metal and other alloy material with PTFE, asbestos and graphite soft material with each other overlap, forming a spiral wound last, the beginning of the end of the winding and the endmost with welded metal strip Welded fixed.

 Spiral wound gasket is a semi-metal gasket compression, the resiliency of the best are less sensitive to the surface of the flange clamping surface defects, not bonded to the flange sealing surface, with a multi-channel sealing and some from the tight to a certain Metal Jacketed Gaskets extent, it can eliminate the influence of pressure, temperature change and mechanical vibration. Sufficient to ensure the sealing performance of the complex high-temperature, high-vacuum, low pressure, shock, vibration, etc. appear alternately in harsh environments.

Its structure density may be based on the need to use to produce, and can be used both inside and outside of the steel ring to control the maximum compaction degree of the gasket. In addition, this gasket demolition convenience, ease of construction workers.
