Large Volume Pressure Testing
Large Volume Pressure Testing
(OP)
Hello,
We have a requirement to pressure test some large volume cylinders (80 m^3) using air however there are some concerns regarding the magnitude of stored energy in the cylinders at the test pressure, which if released in uncontrolled conditions could have detrimental effects to surrounding systems and personnel.
In order to mitigate this we are looking into reducing the volume of the pressurised gas by installing some packing / space filler into the cylinders for the duration of the test. I have searched the deepest darkest depths for companies on the internet that are able to supply a product suitable for this application, without much success. Is anyone aware of anything suitable?
Many thanks

The problem with sloppy work is that the supply FAR EXCEEDS the demand

The test pressure is 50 psi.
Mike, thanks for the link but using balls will not be feasible as installing / removing them may prove some difficulties due to the size of the tubes.
Thanks
RE: Large Volume Pressure Testing
Give us a bit of clue here - what does your cylinder look like? What is the manhole or pipe entry size?
Where do these tubes suddenly come from?
This is like trying to see something through a letter box...

water would also work, but be messy.
sand (in bags) would also work.
anything relatively incompressible.

Solid foam blocks would be a feasible option, are you aware of any suppliers in the UK?

B.E.
You are judged not by what you know, but by what you can do.

Not sure how well foam panels will resist air pressure. Think you want solid PE or nylon.
Can you just sketch this thing a bit if you can't post actual drawings as I can't visualise your cylinders and tube arrangements.

googling "foam blocks uk" got several promising hits.

What about sawdust, blown in sucked out? Cleaning problem? Big-bag held inside?

RE: Large Volume Pressure Testing
Thank you, ScottyUK! I stand corrected!
Worst case could be a pressure overload, 'correct' mixture of dry and fine-grained sawdust with air and an ignition source inside a (partly) intact container. I should have seen this probability myself!
