Process tanks are vessels used to collect material that other equipment discharges. Factories, laboratories, farms and plants use this system. Although commonly made of stainless steel, outdoor process tanks can still accumulate dirt and other residue. Even the steel on indoor tanks will eventually need to be cleaned. The most efficient way for restoring objects of this magnitude is sandblasting, which uses abrasive granules to quickly restore a surface.
Things You'll Need
- Plastic sheeting
- Safety goggles
- Painter's suit
- Silica sand
Ventilate the work site if the process tank is located indoors. Remove all surrounding objects in the area or cover them with plastic sheeting to prevent damage from stray strand.
Put on a respirator, safety goggles and a hooded painter's suit before operating the blaster. Blasting a smooth metal like stainless steel will surely cause the sand to ricochet in several directions.
Power off the sandblaster, then fill its tank with silica sand. Switch on the compressor according to the manufacturer's instructions to allow it to pressurize. It will be ready when the air pressure has reached between 40 and 100 PSI.
Stand at least two feet from the processing tank. Hold the blaster's nozzle an arm's length away, and point it at the stainless steel. Pull the trigger to begin cleaning the surface.
Sandblast the tank from top to bottom for even coverage. Apply short bursts of sand to problem areas or stubborn finishes that require more effort to remove. Proceed until you reach the desired results.
