Pretty soon we will have accumulation of ice and snow.



I was after some info on how to protect machinery, junction boxes, pipes etc from falls from tank tops, infrastructure, rocks etc which are not trace heated.



Bad design layout is one root cause but too late in the day for crying over split milk!



Cheers

Haliho,

Try the "trace heating" search. You will find a lot of info about winterization. If You need more help I’m just finishing a project with trace heating, insulation, cladding and fiber optical temperature monitoring for a gas re-injection system.

Best Regards

Katalin

Ah Ha ! Cladding ! Cladding is what is used for protecting pipes in thermally extreme environments.



If it is not enough for the valves you’ll need to get something akin to an electric blanket in there with it !

Thanks lads.

At 70 degrees north I think something a tad more robust is required.

Any calls from semi tropical Sakahlin Island or the North slope?

Hi Gwen,



Now I understand pack your thermals !



I used to work in a clean room with lots and lots of valves and pipes: mostly routing nasty chemical gases.

Temperature stability was an issue but did not matter becasue variation was typically only 21deg C +/- 1degC.



I’m guessing these are robust outdoor valves subject to potentially extreme temperature.



Key things are: (1) valve still works as required; (2) No leaks caused by frozen parts/pipes rupture; (3) warm enough to maintain flow ( fluids).



In Scoland I would use cladding. There are undoutably special valve "cladding fittings" someone has in a store somewhere.

Try searching cryogenics, or something like that, it means cold conditions.
