Product Description
Inner and outer ring metal spiral wound gasket
The inner and outer ring metal spiral wound gasket is a commonly used sealing material, consisting of two inner and outer metal rings and a middle packing layer. It has many characteristics. The following is a detailed introduction to you from the performance, use and other aspects:
Performance characteristics
1,Good sealing performance: Sealing is achieved through the deformation of the packing layer. When the flange is connected, the packing layer is compressed, the volume shrinks, the air gap disappears, and a good sealing effect is formed. At the same time, the metal ring is elastic and can adapt to the uneven surface of the flange, effectively preventing leakage and the intrusion of external impurities.
2,High pressure resistance: Due to the advantages of metal materials, it has a high pressure resistance, can withstand greater pressure, and adapt to high temperature and high pressure environment requirements.
3,Good temperature resistance: It can maintain stab
le performance in a wide temperature range. Different filling materials have different applicable temperature ranges. For example, the applicable temperature of graphite filling materials is -240~550ºC, the applicable temperature of asbestos filling materials is -150~450ºC, and the applicable temperature of PTFE filling materials is -150~280ºC.
4,Strong corrosion resistance: It can select suitable metal materials such as carbon steel, stainless steel, copper, etc. according to the properties of the working medium to ensure its corrosion resistance and maintain a long service life in the working environment of nitrides.
5,Good wear resistance: In the long-term use process, it can resist friction and wear to ensure the sealing performance and service life of the gasket.
6,Good compression resilience: It has good compression and resilience, does not stick to the flange sealing surface, is easy to disassemble and assemble, and can partially eliminate the influence of pressure, temperature changes and mechanical vibration.
Usage characteristics
1,Wide range of applications: It is widely used in pipelines, valves, pressure vessels, condensers, heat exchangers and other equipment in the petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries.
2,Adapt to special occasions: It is particularly suitable for occasions with uneven loads, easy relaxation of joint force, periodic changes in temperature and pressure, and shock or vibration.
