Frozen valves and instruments on a remote site are a common and frustrating experience in the oil and gas industry. The downtime and loss of productivity that happens due to a freeze are even worse – you’re losing money every hour that your equipment isn’t working properly.  Freezes don’t just happen due to low temperatures, though that’s certainly a common cause. Large pressure cuts also frequently freeze valves due to the Joule-Thomson Effect. That means valves can freeze at any time of year – even when you’re least prepared to deal with a freeze.
