Copper gasket.

Dear Kannan,

Good Morning!
I do repeat again that the problem case is a simple SPW gasket case.
I find it difficult to convince myself while wasting my effort on
somebody's fertile idea of using copper gasket.
Regarding your sportive comment, please do appreciate it is a non-code
example of using expanding flange. Such type of flange is indeed a safety
hazard for higher pressure rating.
I can do the "re-inventing of wheels", if I have time and certainly not in
this unsafe case.
Pertaining to your alternative solution "...Coming to B16.5 compliance, the
other alternative, if it is few points in the plant, replace the 2" flange
with 2.5" x 2" ...", kindly ckeck the boring size limit in the B16.5 table.
Thank you again.

Kind Regards,
Bhatta.

Additionally, for our Bhattaji as quoted below,

"I think that you should also similarly respond to site, without breaking your
head."

These problems do occur due to the negligence of the white color engineers siting
in A/C office and doing poor engineering. So white colors do have to break thier
heads to find solutions to thier mistakes as we are called as engineers by our
site colleagues. So we have to engineer it.

This problem is a well known purposeful ignorance by the piping material engineer
who does not co-ordinate with the instrumentation specialist. And he ignores to
comment or talk to piping material engineer. The big excuse and a fact is that the
orders of the intruments are placed after the instrument assembly specification
prepared by the piping material engineer is closed and forgotten and IFC
isometrics is in progression.

So the site can be spared only at the will of the two colleagues involved.

Just a sportive reply dear bhatta.

Happy piping.
Kannan.
