"HF alkylation units screwed connections for instrument"
(OP)
In HF alkylation units all screwed connections for instruments require (Heavy-duty industrial-grade “extra-dense” Teflon “R” tape). Is it acceptable to use the same Teflon reference in the liquid form? What are others experience on inspection of screwed connections? As you see for safety reasons this is an important item which most of the time is forgot and leaks happen with consequences for operations, inspection and maintenance instrumentation.
From forum experience what are others procedures and experience for on line inspection of these screwed connections?
Thank you to the forum empathy.

If you are relying on the tape to help seal then you have different issues to deal with.

RE: "HF alkylation units screwed connections for instrument"
I also would like from other refineries experiences in HF alky units what are the routine practices of on line inspection of screwed connections. We are thinking to start a programme of digital Rx inspection of screwed connections where practicable, according to a planning base on fluid criticality of the connection.
