Lagging external gas pipes

Jan 23, 2015 Last reply: 2 years ago 27 Replies

In a camping barn in N. Wales the solution that I used was to sit the butane cylinder (bigger than the little camping stoves' size) on one burner of a two burner stove. The other occupants were a little worried, but even an hour later there was condensation and a bit of frost on the cylinder. Not recommended in a tent.

Thanks for comments: I have since asked him more: he was told that it was because LPG could be mixed with natural gas in the future - I am unsure whether that is correct or not (I do believe he was actually told that - probably incorreectly). It is a mains gas supply.

In the case of butane, formally used by caravanners amongst others, in blue bottles the gas simply ceases to boil off and sop you loose any pressure. Some poor souls thought that wrapping the bottle in a blanket might help keep it warm. Hence with winterised caravans most people now use propane - red bottles. I forget the exact boiling point.

Methane - even lower boiling point.

At a very very low temperature

Comment from UK: Conversations here going on about pipe issues gets too cold but none on warmth. Having own issues on outside gas pipe goes straight from ground up side of the property into ceiling where see valve, (ugly) and to boiler where is, in kitchen. But not once anybody on here mentions heat expansion noise issues. My pipes directly in the sun and expands & contracts making a loud clicking and bang least hundred times a day. Noise can be heard outside and inside, driving myself nuts. Hoping bit of lagging may protect pipe from sun exposure and get pipe too hot. Nothing to do with the boiler itself!
