Does this means Mechanical Seals have to be ASME qualified . Hence, Mechanical Seals needs to have qualifications as per ASME requirements.
I am totally not clear about application of ASME on Mechanical...
Please provide some information about.
Is Mechanical Seal fall as pressure boundary as per ASME. Or does it's seal faces falls under the pressure boundary limit. I am unable to find explicit answer to this question.
Please provide any ASME article reference to clarify.
