Mike,
Thanks for your reply but AI refused it saying its an ASME code requirement.
Can you provide some technical backup to convince AI? It will be very much helpful.
David,
I know that as per code it is 1/4" max. But is there any way to accept 1/2" as practically it will not create any issue. We have also verified the reinforcement calculation with this 1/2" size.
Currently it is not possible to make the 1/4" size hole on the pad.
Please advise if you...
Is Telltale hole size more that 1/4 inch NPT is acceptable for ASME Sec VIII Div I vessel?
In our one of the equipment we made the Telltale of size 1/2 inch NPT and ASME inspector is not accepting the same.
What is the problem caused if the Telltale hole size is more than 1/4 inch NPT?
