ASME B16.34 / Body Minimum Wall Thickness

[krkim]

at B16.34 / 6.1.2 Inside diameter,

Any one can explain me the inside diameter 'd' of safety relief valve, and 'basic inside diameter'?

See Attachments.

Thank you.

Basic inner diameter values are used as parameters related to wall thickness and consequent pressure rating, and inside diameter is the nominal bore value, which is related to flow calculations.
