(1) Acquisition Phase: Outsource hydro testing on LOx and Aluminum. #23

Ensure that company understands that we have modified the aluminum tank (drilling through bottom).

The tanks will need to run at about 700 psi, but we need a safety factor. One tank is aluminum, the other is steel. We can probably just have them tested against the DOT standard printed on the tanks.

Below is a list of companies that will do hydro testing for $20 (so we hear) and are aware of the special procedures for galvanized tanks as well as checking the REE # to give a tank a + rating on the hydro.

From Hydrostatic Testing FAQ

All cylinders have ratings that start with “DOT” or “ICC,” followed by the service pressure of the container. For example “DOT 3AA 1800” means a DOT approved cylinder made to the “3AA” specification rated for 1800 psi.

We have the equipment to do hydro testing ourselves. At this point no need to outsource it...
