Freezing of pilot sensing lines
Freezing of pilot sensing lines
(OP)
Hello I have a quick question. What effect does freezing of pilot sensing lines have on its operation? Pre mature lifting? or potential for overpressure? Any insight will be appreciated. Thanks

Heat tracing and insulating pilot lines is a very good practice.

I am presuming the source of freezing is due to ambient conditions. If the freezing is due to process conditions, heat trace/insulate may not work and you will need to find alternatives.

RE: Freezing of pilot sensing lines
However, I still dont understand why it will NOT open when it reaches set point due to sensing line freezing up. The operators i spoke to said they haven't seen this before. Can some one explain if this is indeed a likelihoo?
Thanks.
