Pressure testing 63mm gas pipe

[mutley racers]

Bingo.........

There you go mip 75 mbar

Mop 23

So test would be 82.3 so 83mbar so you could test the mdpe at 100 mbar

Thanks for the calculations. As I don't have a gauge that does 100mb, I could do this as you suggested in the 1st place to 1 bar as it is only a soundness test after all. But, as you say it is commercial so should I avoid.

Well if one thing that comes out of this I have learnt a bit about cost of fittings for this size pipe and strength testing.

Thank you all

Upto you as it's not connected you could say your only testing the pipe for defective not carrying gas

I was thinking so much.

So what size manometer do you have for these tests any way

 

[ShaunCorbs]

Don't have one

Got a dial gauge eg pressure and an anton 140

I wonder what pressure my kane455 goes upto

Think mine is 75mb

Interesting tools. Don't think I could find one for the diameter of pipe though

Waste test plug depending on internal bore

So went to pressure test this job but the pipe was not installed to regs. They had run yellow mdpe into the building which if I remember correctly is a no.

I do know the gas board do this though when replacing the mains to the meter inside the house with mdpe by pushing it up the old pipe.

Not the most revealing to be honest. Not much to see.

The pipe goes under the building just to the left
