Hydro Test

[TMHeimer]

Just curious. I believe a tank is filled with water for the test. How do they get the inside completely dry afterwords?

Depending on where you take it some don't. When you get it back it may need a quick whip or tumble and rinse/dry to get rid of the flash rust left in steel tanks. In al not such a pain. The hydro place we use only wants the tanks, not the valves. He dries, bead blasts if necessary, and O2 cleans them for one price. When they come back they are pristine.

What I do to get the water out is simpley hook a vaccumn pump up and pull a vaccumn on the tank, close the tank valve after 10 or 15 minutes. Then hook up a charging lead and fill tank. Water boils at a very low temperature under a vaccumn. 29" vaccumn water boils at about 80 degrees I think thats close.

My hydro facility uses a rust inhibitor in the water. They inert the cylinder with helium to dry it.
