Testing gas pipework for extraneous conductive parts

[ellerkerj]

Just checking before I blow a hole in the wall that using an IR test at 500v is ok on bottled gas pipework. Seems like the sort of thing that in hindsight you'd wonder why you thought it was a good idea. Could disconnect the bottles, but that would seem to make the test pointless.

Flammable or inert gases and is the area subject to any ATEX hazardous area zone classification would be first thing I would check before flashing around at 500v.

why dont you do a continuity test

I take it this is for a domestic or small commercial property, in which case follow the normal course you would with town gas...

Seeing as gas bottles are generally connected to any permanent metal pipework via a flexible rubber pipe onto a pressure valve that push fits onto the gas bottle, i'd say it wouldn't matter a jot one way or the other!!

Some have a wire braid embedded in them which will form an electrical connection.

Only if those flexible tubes with wire braid are fitted with a screwed connection. Most if not all of the domestic bottled gas connections i've ever seen is via a short bit of rubber pipe that is pushed onto spout connections with a pressed fitted clamp one end, and the other a jubilee type clamp onto the pressure valve that in turn is push fitted onto the gas bottle... Maybe the larger bulk gas bottles for commercial or small industrials have wire braided screwed connections, but i doubt many domestics do...
