Hydrostatic testing

[fegenbush]

Do you have Airgas, BOC, or some other welding gas supplier that is local to you? Here, I take it to the local welding supplier. 161 bar is not insane pressure in the world of gas cylinders.

Check with a local boiler/pressure vessel manufacturer or qualified repair shop. They should be equipped to handle hydrostatic testing.

Thanks people, I did try BOC and they did not have a clue.

I have found a diving place that looks good.

lifornia, we exchange the bottles at the supplier, when due is a blessing; they take care of the certification and with the exchange we get a fresh tested/certified tank. any gas tank.
may be your supplier can do the same!
