Wrap gasket material
Thread Content
For gaskets of the same size, such as those for DN100, if they have different pressure ratings – for example, one with a pressure rating of 150 lb and another with 600 lb – are their materials the same? Since they are used at different pressure levels and thus require different sealing forces from their flanges, should the material be different as well?
Depending on temperature, medium, and pressure, the material of the gasket must be selected accordingly
The material is not chosen based on the sealing pressure; it depends on temperature and the medium involved. For example, 4F gaskets cannot withstand high temperatures, while metal gaskets may corrode
When choosing such things, one should do so based on specific requirements and look for suitable options in the market. There’s no need to worry about the material. If quality issues arise with the selected product, liability can be pursued in accordance with the contract. Regarding the material, it may be the company’s intellectual property. Speaking of that 304, who is capable of conducting analytical tests on it??? For reference.
Wrap gaskets have certain application ranges; as long as the application range meets the requirements, the material can be the same
The materials used are the same; only the sizes differ
At the same medium temperature, only the pressure differs; the gasket material remains the same
Not necessarily. It mainly depends on the settings during design. And the corresponding standards or specifications adopted.
