Choose the ends of a small valve
Choose the ends of a small valve
(OP)
Good afternoon,
I'm busy with some small modifications on existing pipelines designed according ASME.
1 of them contains the installation of a small valve <1" as drain on a Flare line.
The process engineer wants a flanged valve but the current pipe spec tells me to install a SW valve.
Is there any reference to an ASME code "rule" that you can choose the right end by fluid code/pressure/temperature?
It is a modification so why don't deviate the pipe spec, if it's off course acceptable.
Kind Regards,
Ruud

To deviate from the piping spec you would need to revisit the philosophy behind it, so probably just easier to install a valve with SW ends.
