R/G type metal spiral wound gaske
R/G type metal spiral wound gasket is a commonly used sealing element, widely used in the following fields:
1. Petroleum and chemical industry: used for sealing flange connections of pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc.
2. Power industry: used for sealing high-temperature and high-pressure steam in mass equipment in power plants, such as boilers and steam turbines.
3. Metallurgical industry: used for flange connections of various furnace equipment in the steel manufacturing process.
4. Ship and machinery industry: used for flange connections of ship engines and mechanical equipment to ensure the sealing performance of the equipment.
5. Medicine and aerospace sectors: used in these high-demand industries where highly reliable sealing is required.
Performance:
1. Resilience and compression performance: Due to its unique structure, the basic metal spiral wound gasket has good resilience and compression performance, can effectively adjust the vibration of the pipeline system, and is more suitable for pressure changes and vibrations.
2. Multi-pass sealing and self-tightening function: The gasket has multiple sealing lines, which can achieve self-tightening function to a certain extent. It is not very sensitive to surface defects of the flange compression surface, does not adhere to the flange sealing surface, and can partially eliminate the influence of pressure, temperature changes and mechanical vibration.
3. Applicable to harsh conditions: The basic metal spiral wound gasket can maintain its excellent sealing performance under various harsh conditions such as high temperature, low temperature, high vacuum, impact vibration and other cyclic alternations.
4. Adjustable structural density: The structural density of the metal spiral wound gasket can be made according to different locking force requirements, and the inner and outer steel rings are used to control its maximum compression.
5. Corrosion resistance: Usually high-quality SUS304, SUS316 and other stainless steel winding belts are used, which have good corrosion resistance.
In summary, the basic metal spiral wound gasket has become an indispensable sealing solution in many industries due to its excellent sealing performance and wide applicability.
