OVERVIEW
Two water tanks located in Dayton, Ohio required blast cleaning. The tanks had an internal surface area of 28,000 ft2 – with external surfaced of 45,000 ft2.
The tanks are supported by a large central riser column and 12 legs around the circumference. Access is via swing stages. Catwalk platforms are suspended between the columns.
PROJECT OBJECTIVES
Achieve surface cleanliness and roughness standards.
Ability to complete project deadlines on-time.
Generate considerable savings.
RESULTS
We performed two tests on equally sized towers. The first test used coal slag and the client’s original equipment. The second test used GMA ToughBlast and two Mega Blasters with 1600cfm compressors.
Tank #1: Coal Slag
.
Abrasive consumption
380 tons
Total labor hours
1728 hrs
Nozzles used
6 to 7 for 12 hrs/day
Downtime
670 labor hours. Disposal $22,000
Tank #2: GX2
Using 2 MegaBlasters with 1600cfm compressors
Abrasive consumption
220 tons
Total labor hours
1350 hrs
Nozzles used
5 to 6 for 10 hrs/day
Downtime
Minimal. Reloading once per day compared to 2-3x previously.
CONCLUSION
By switching to GMA ToughBlast, our client used 44% less abrasive. Additionally, they saved almost 400 labor hours. Downtime during blasting was significantly reduced. This is due to minimal reloading of the Mega Blasters. Altogether, there was a total savings of 22%. Moreover, he was able to move the equipment on a week ahead of schedule to start the next project.
“I can work shorter days as I don’t have to stop to let the dust clear to see what we are doing! There is basically nothing to clean up!”
