Commercial gas courses

Don't matter, it's 35mm

Far be it for me to question your wisdom John but IGE/UP/1B Ed. 2, which covers domestic gas states that:

Pipework of diameter less than OR EQUAL TO 35mm is allowed on a domestic ticket subject to TIV being less than or equal to 0.035m3, U16/G10 meter, OP ~ 21mbar and MOP being equal to or less than 2bar.

Fig.1 on page 3.

I can never remember if it's one way or t'other. I do remember the 35 bit though.

Smart arse.........

Heh! Just spent 3 weeks having that drummed into my head LOL.

What I still can't get my head around is that you can have a TIV above the limit but if you split it into sections with ECVs and test points, you can work on each section on domestic...

Handy to know masood but to be clear im thinking right....

Basically legs coming of a main commercial carcass that have an ecv and test points and where that particular leg in isolation (downstream of the ecv) conform to /1b can be worked on a domestic ticket..??

Sort of makes sense thinking about it logically if im understanding you right.

It's all about the volume of gas you are likely to purge.

As well as what gauge you're going to use as each type has a maximum ttd.
