  • Vapour (CO2) blasting tank interiors?

    Has anyone attempted C02 (Vapour) blasting to clean the interior of a fuel tank?

    This type of blasting uses Co2 media that vaporizes upon contact, no media residue, just the rust and dirt which is not much different than the rust residue using conventional methods that depend on flushing after loosening the rust particles.

    Used extensively on high voltage insulator type equipment in substation because it's gentle and does not leave the residue from walnut shells and the like.

    Dimitry offered a vapour blasting service. Maybe he has some experience with fuel tanks.

    Don't spend money and buy, spend time and learn.

      CO2 is different from vaporblasting, neither works well on Hawk tanks because you can't point a nozzle 180 and ther's only one good size opening that the nozzle will even fit through. My best results have been getting a length of chain or just loose nuts and bolts packing the tank in the couple of moving blankets and sticking it into the clothes dryer on "tumble" NO HEAT.
      Might take several hours as you have to reposition the tank few times after each cycle is complete but once it's done you fish out the chain and rinse the tank. We used to use loose hardware but it's a lot harder catch straight nuts and bolts out of the tank then chain.
      In the end I would rinse the tank with water and then use a bottle of 90% alcohol to do the final rinse, It absorbs the water and once you drain it out it dries fast.
      After that I would use Caswel epoxy, tried a few different things and Caswel seems to work the best

        So a direct nozzle blast is still required. Asked and answered. Thanks Dimitry for the reply.

        Not CO2? - Can you explain want kind of abrasive is used? A form of Water jet?
