Regarding the inner ring gasket, regardless of the pressure rating?
Thread Content
For the same nominal diameter, regardless of the pressure rating, the size of the inner ring gasket remains the same. Can it be understood that, regardless of the pressure rating, as long as the dimensions are correct, it can be installed? Could there be an issue with the strength of the wound steel strip?
Is the poster referring to the thickness of the gasket? Personally, I think the thickness of the gasket is related to the size of the flange, and it has little to do with the operating pressure.
This type of gasket is generally used with male and female flanges
There is no issue with the strength of the winding steel strip
The issue with the winding gasket ring is not one of strength; what the original poster said earlier can also be understood in that way
Gaskets serve a sealing function; after the flanges are connected with bolts, the deformation of the gaskets fills in the tiny irregularities on the surface of the flange metal, thereby achieving a sealing effect.
It can be understood in this way: wound gaskets also do not have any issues related to sealing surfaces; as long as the dimensions are appropriate, they function just like RF and MFM gaskets. You can refer to JB4707 or HG20610 for more details.
The one on the 7th floor should be JB4705, right? JB4707 is the stud standard
