Safety during Hydrotest
Safety during Hydrotest
(OP)
Hello members
A query related to safety during hydrotest of pressure vessel.The hydrotest pressure is 285 bar. Are there any guidelines for safe cordon off distance for various pressures during hydrotest?
For lower pressures we used to maintain arond 2 metres cordon off distance. since this vessel will be tested in fabrication shop where other works will be underway in adjacent areas we need to have a safe cordon off distance
Any help will be greatly appreciated

Of course, a totally different criteria applies to pnuematic tests.

Many years ago the company I worked for was hydrotesting some 24" spools that had Victaulic fittings on the ends. During hydro one of the ends let go and sent a 2" thick blank hurtling down the shop. It travelled about 40 feet or so before coming to a stop. We were lucky in that no one was hurt, and we had an opportunity to reevaluate our procedure.
By the way, I'm not bad mouthing Victaulic fittings. During our investigation we determined that our machining tolerances we're not tight enough, and that the clamps were not designed for multiple cycles.

Nevertheless, the pressure itself is not so dangerous as some might think of. The water used is always just at ambient temperature even though the pressure can be high, such as your 285 bar, but is still about as much as that of some high-pressure household pressure washers. You don't normally hear people badly injured or even killed by pressure washers even though being directly shot at. Only high temperature water or steam, even at low-enough pressures, are the dangerous killers.
