thread378-235027: Pipe testing - Air vs water testing
Alot has been said for the dangers of Pneumatic Testing compared to hydrotesting.
Due to the serious consequences that may erupt during pneumatic testing, is there a way that we can protect testers due to a possible eruption or explosion?
Such as for cylinders limited in size, can we test the cylinder to the required pressure (say 600 psi) with Nitrogen while being inserted in a pail of water or other. What would be the effects if the cylinder erupted and failed the test?
Or, without the use of a water barrel, can we utilize an open ended container (preferably see through) and insert the container within and conduct our pneumatic h-test?

I would check the Cylinder Gas Association site for some information. If you are near a Scuba Dive Shop you might check with them for their codes as they still check dive cylinders under water.

It would be best while filling the canister to visually identify any leaks or other during the test.
