Basic concepts of metal spiral wound gasket sealed
The gasket seal pressure vessels, process equipment, power machines and connecting pipes detachable connection at the main seal type industrial installations, usually called screw flange connection flanges, bolts, nuts and washers, they in which the conditions of public funds is complex, the the sealing fluid medium wide variety to prevent liquid or gas through the gasket (metal spiral wound gasket) sealed connection leaked at the factory to face the most important and most difficult task.

Gasket seal and rotary mechanical shaft seal, reciprocating mechanical shaft seal, valve stem seal compared to the leakage rate is not great, but the wide range of large gasket seal, so that they become the main source of industrial equipment leaks . Leaks ranging from to cause wasting a lot of energy, raw materials, while cause of equipment downtime, casualties and serious environmental pollution.
