hydrotesting

[Raphael Warshaw]

Does anyone know of a place in northern New Jersey, southern New York
or eastern Pennsylvania that will hydrotest a carbon filament-wrapped
oxygen bottle (MH part number 480). The best solution I've found so
far is to ship it back to Mountain High with a 3 week turn-around.

Thanks,

Try dive shops, but they may not have the ability to test to the
(3,000psi spec) pressure needed for this cylinder. Also ask your local
fire department where they test their SCBA cylinders. Many of these
will use similar cylinders.

Scuba tanks are usually filled to 3,000 psi and rated to 4,000 psi, so
they will know how it's done.

But few if any scuba shops can test themselves, they usually send the
bottles to a test facility. Which means that it won't be much faster
than sending them directly to MH.

Call your local welding supply house. Places like TriGas, AirGas, etc.
will have someone local they use or can probably get you to someone who
knows.

I get my bottles hydrotested at a fire extinguisher business. Next
day turn around at several places.

I'll second what Guy says, call some fire extinguisher companies.

Do not use your local welding shop. Did that once and they beat the snot out
of a previously new looking aluminum bottle. With a composite bottle it
might be much worse as they don't want to get bonked. Welding supply shops
typically do not do their own testing, instead ship a bunch of bottles to a
test facility. Probably the shipping to and from where the damage is most
likely.

Ray,

Try a Fire Extinguisher shop, that's where the SCUBA folks sent
me. They were great, This shop only tests twice a week, so 4 day
turn-around. Reasonable price, around $25 as I remember. They
answered all my questions. Also, I asked for and did get a tour of
their test facility and an explanation of how a cylinder is tested.
It was all very interesting and worth a quick tour.

Thanks to all who answered - the solution was a fire equipment company
(Chief Fire Equipment and Service Company, Lodi, NJ). They take two
days and charge $ 17.75 plus tax.
