1300 compressor, 1600 CFM Desicant Dryer, Clemco 6 bagger pots for mobility around job, and used Dupont Starblast. Much faster than coal slag on new steel. Was running three blast pots on this tank.
The surface profile was around 2.5 - 3.0 mils. The Starblast is a rounded abrasive but the coating system used takes to it very well. As far as pressure, the pressure was running around 125-130 psi at the Blast Nozzle. I don't think that you would want anymore pressure than that. I always check my nozzle pressure on each job to see how much loss I have at the nozzle. We ran a 1600 CFM unit at 150 psi with two blast nozzles running full time. What pressure would you recommend?

What kind of Setup are you guys running (compressor, sand pot, steel grit, Water trap)?

yea but what is the surface profile here? If I remember correctly this abrasive has rounded edges and the pressure doesn't seam to high...

@painter213
no no, I agree with you, just didn't realize that the pressure is at that level. What type of coating was applied here?

Epoxy High Solids System.

The blasting was not slow at all. Took less than two days to complete the blast and the prime work and the blast was a SSPC-SP10 Near-White Blast.

kinda looks slow but it is what it is
