ASME B16.36 drill customization
ASME B16.36 drill customization
(OP)
Hi there,
I'm facing an issue regarding an application within a piping system which has a 150# class and the customer is asking if is it possible to make a welding flange, NPS 4", based on ASME B16.36 class 300# thickness but with a modification to 150# drill pattern.
Could someone help me please? Thanks in advance for all your support.
Best regards,

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Thank for your reply. I agree about the engg logic as well as the lower pressure rating due to the thinner section of bolts/studs. The main concern is related to make an orifice which includes a tap for instrumentation purposes, so the MAWP of the piping system will be limited to the class #150, which is the design pressure.
The hard work is to convince both the project engineer and the inspector to accept this solution.
