External Gas Pipes

Autolycus · 2008-01-06T15:46:34+00:00

I need to replace an existing run of 15mm gas pipe with 22mm. It runs from an external meter box, around 4m along the outside wall of a bungalow (a couple of feet from the ground), then vertically upwards, then through the wall. I will sleeve it where it goes through the wall, in line with usual standards.The existing pipe, installed by the Gas Board in 1986, is bare copper: is this still acceptable? The wall is not in an exposed location, and is not accessible to public or casual visitors, or vehicles. If bare copper is no longer recommended, would covering it with something like BES Part No 10865 be OK? I think Denso would be unacceptable visually. I'd prefer not to use the plastic-covered stuff if there's any alternative.

But possibly illegal for gas work because it's not an approved gas fitting!

It is not actually a fitting, which joins pipes. It is one pipe soldered to another.

That's just short of being struck off by the sounds of it.

The swaging (sp?) tool is apt to become stuck. The inside of older pipes is hard to clean.

Looking through BS 6891 there does not seem to be an explicit prohibiton on swaged connections but the intention of the document is that capiliary fitting would be used.

Wet side only in this instance.
