Crude Oil Storage Tank
It was a tough-as-nails millscale, but when we hit it with Garnet — it came off like butter.
The new crude oil tank in Taft, California, was similar to the others — 46 feet in diameter and 21 feet high. It had just been built, but tightly adhering millscale was proving a tough proposition for the contractor blasting it off. “We started off this project using a 35 mesh slag, blasting the underside of the roof and three-and-a-half feet down the sides,” Arturo, the project Foreman said. Blasting this 2,200 square feet roof, this contractor had taken four days with two men, and used 24 ton of slag.

The contractor then used SpeedBlast on a section of 10’ 6” up the wall.
It only took my two men one day to blast completely around the tank, 1,500 square feet — using only two ton of abrasive. Needless to say, we ordered Garnet to finish the rest of the tank. Arturo said.
Due to the productivity difference, Arturo wants to take this to corporate so he can reap the benefits on every project where he is a supervisor.
