Very good v-log. 👍💯🌹

PTW was made or not ??

Where’d they build this place, Minecraft? Those mountains in the background. Lol

There are more reasons to do a hydrostatic test than ensuring that the foundations are strong.
Hydrostatic testing is more often done as part of industrial standards for storage or pressure vessels. Water is used and the vapor space in the tank is eliminated by the filling.
It seems that for this accident to happen that something else was done; The flame arrestors on the vents had to of been removed. These are mechanisms that prevent a flame from making its way back in to the tank. You can still get a fire on top of the tank while it is being actively filled but it will not cause the contents to combust.
The tank (including the sump area at the very bottom) should of been completely drained and flushed. Draining the sump area is hard to do (it can hold a few hundred gallons of product). The piping to the tank should of also been removed and flanged off (to prevent leakage back in to the tank from the piping).
Then the tank should of been nitrogen-purged to put an inert atmosphere inside the tank.
NOBODY should be working on or near the tank during a hydrostatic fill or test. Later in the hydro process when the tank is completely filled with water the openings at the top are then flanged off and the tank is pressurized with water-only (no vapor space is allowed at all). Then the tank is over-pressurized up to its rating and held at that pressure. Meanwhile it is inspected for leaks, bulging or volumetric changes (shows up as pressure loss beyond what may happen from temperature changes).

2 activities at the same time and same place is not to be permitted as one can be a cause of other circumstances.

how to develope animation like this which software used

[@davidsharples4677]

The tank API650 should have all HOT work completed before hydrostatic testing

[@HonkousBonkous]

Well said, David!

[@nurhafizayahya9832]

Appreciate if could share where, which company and when this accident happen.

[@FaithS679]

Phillips petroleum

[@OwaisAnsari-qk6xr]

Exactly. As a Trainer, I also need this info.

How is pumping gasoline through my power washer not normal? I do this all the time.
