The performance characteristics of the outer ring metal wound
gasket:
Spiral wound gasket has good compression performance, good resilience, multi-channel sealing and certain self-tightening function. It is not sensitive to the surface defects of the flange pressing surface, and can partially eliminate the influence of pressure, temperature changes and mechanical vibration; it can be used in Under various harsh conditions such as high temperature, low temperature, high vacuum, shock and vibration, etc., it maintains its excellent sealing performance.
Use equipment: sealing of flange connections such as pipes, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc. in the petroleum, chemical, metallurgical, electric power, shipbuilding, machinery and other industries.
The inner ring metal wound gasket is generally made of the same material as the wound steel tape. It meets the corrosion resistance requirements of the pipeline medium and is usually better than the material of the pipeline or flange. According to the standard requirements, the metal wound tape is first fixed on the inner ring, and then the metal wound tape and graphite are used. , asbestos, tetrafluoro, non-asbestos and other non-metallic winding belts are continuously alternately overlapped and spirally wound, and the metal belts are fixed by spot welding at the end. The inner ring metal spiral wound gasket is also called the reinforcement ring to avoid the loose ring of the spiral wound gasket.
The performance characteristics of the inner ring metal wound gasket are as follows:
The control of the inner ring enables the gasket to obtain a high degree of compaction, and the surface accuracy of the flange sealing surface contacted by the wound gasket is not high. The gasket is especially suitable for occasions where the load is uneven, the joint force is easy to loosen, the temperature and pressure change periodically, and there is impact or vibration. It is generally used in medium and low pressure tongue and groove surfaces and flanges with flat or concave and convex surfaces.
