All kinds of pipes need metal spiral wound gaskets, so that the connection between pipes and pipes can be more compact and tight, but the role of metal spiral wound gaskets is not only this. The metal spiral wound gasket can also adjust the uneven load of the pipeline and other functions. Each type of pipeline requires a corresponding metal spiral wound gasket to make the gasket play its best role. Naturally, metal spiral wound gaskets will have various standards and sizes in order to correspond to various pipelines. So what is the scope of application of metal wound gaskets? What are the standards of metal wound gaskets? Let the editor take you to find out.
Scope of application of metal spiral wound gasket:
The metal spiral wound gasket with excellent resilience can automatically adjust the pressure thermal cycle and vibration of the piping system, especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. It is the original static seal for flange connections such as valves, pumps, heat exchangers, towers, manholes, hand holes, etc. It is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other departments.
Material of metal wound gasket:
Metal spiral wound gaskets are made of high-quality SUS304, SUS316 ("V" shape or "W" shape) metal strips and other alloy materials and graphite, asbestos, PTFE gaskets, non-asbestos and other soft materials alternately overlapped and spirally wound. Finished, fix the metal strip by spot welding at the beginning and end. Metal spiral wound gasket is the gasket with the best resilience among semi-metal gaskets. The structural density of 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, winding The surface accuracy of the flange sealing surface in contact with the gasket is not high. Metal spiral wound gaskets are especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. Spiral wound gasket is a static sealing original for flange connection processing such as valves, pumps, heat exchangers, towers, manholes, hand holes, etc.
Application range of metal spiral wound gaskets: sealing of flange joints such as pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc. in petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries.

The role of Die-formed Ring metal wound gaskets is not too big. Various standards correspond to the specifications of different regions, so that metal wound gaskets can play a corresponding role. Moreover, the scope of application of metal spiral wound gaskets is still relatively large, not only in petroleum, chemical, etc., but also in metallurgy and electricity. It can automatically adjust the slight changes between the pipes, so that the compact performance between the pipes can be guaranteed for a long time. Whether it is because of the changes of the pipes themselves or because of the changes of external factors, the metal spiral wound gasket has a very good effect.
