There is a non-standard flange on site, and standard gaskets are required; by how much can the gasket protrude beyond the inner diameter of the pipe?
Thread Content
I checked ASME B16.20, which states that the maximum penetration depth into the pipe is 0.06 inches. Are you all following this standard? Are there any other requirements?
Yes, according to ASME B16.20 standard, the gasket may extend up to 0.06 inches into the pipe. If there are special design requirements or specific requests from the customer, other regulations may need to be followed. In the absence of special requirements, it is recommended to follow ASME B16.20 standards. .
The main consideration is the impact of protruding parts on the medium in the pipeline, such as increased resistance and turbulence. The inner diameter of the gasket also ensures that the sealing performance of the intermediate seal remains within acceptable limits, preventing excessive deformation.
