@thesticklawson , Wow, way to be excited about a garbage abrasive like "black beauty"....lol. With all the heavy metals they are discovering in your abrasive, it will be banned very soon.. Keep up the great work!!!!

What ? ? ? two blasters 7000 to 8000 square feet a day. I can blast 10,000 square feet a day on a open exterior tank shell every day, but not everybody is old school CBI, not by a long shot.

All exterior tanks are erected before the sandblasting comences. You can usualy blast between 7000 and 8000 sq ft of surface area a day. Including sealing it with a primer. With 2 sandblasters. This is obviously dependent on a number of things. The thickness of Mill scale and the blast media that is used. The compressor pressure. The experience of blaster. The more years is not always better though. You have to do it right.

I don't get this either... I work in the Triangle area in Texas and we sandblasts tanks every day... We rarely do hydroblasting on them, but that's just because the refinery wants that... and my guess is because of the price and that's what the tank needs.. not because of restrictions

So where is it that you are doing this work that you can abrasive blast the exterior of a tank? I was under the impression that you could only use the hydroblast method.

Don't know where you got that information at. Abrasive Blasting is done on the exterior of tanks every day. There is no Hydroblasting standard that is for only tanks. I'm in the USA just like you. Drive around Houston and see the tanks being done. They are done all the time. About the only time that Hydroblasting is used is to remove lead base coatings at times. Hydroblasting does not lay down a Anchor Profile that is needed for coatings.

I am in California. I work in the tanks department for an energy company. There are restrictions on abrasive matter emissions in California.

I am doing work for the Department of Energy now in Washington State. In California all you have to do is place a containment up and have ventilation with a Dust Collection System. Abrasive Blast all day long.

That was a New Tank, so it was just surface rust and Mill Scale. Not really sure of the Sq. Ft. per hour rate. It was pretty good though. We used Starblast for the Abrasive, so we used about half of the abrasive if we had of used Coal Slag. We would blast enough to get primed in the same day using rollers.
