ABS Blast for Storage Tanks and Pressure Vessels
Storage tanks and pressure vessels require surface preparation around cylindrical shells, heads, saddles, nozzles and welded details before protective coating. ABS Blast equipment for this work can include blast rooms, abrasive blast booths and media reclaim systems. Double D Mechanical installs, relocates and services the air, exhaust and utility connections around these finishing systems.

Cylinder Handling And End Clearance
Tanks and vessels need room for rollers, saddles, cranes and access around both ends. The layout should consider rotation, nozzle projections, manways, ladders and the path from fabrication into blasting.
Nozzles, Saddles And Weld Detail Prep
Abrasive blasting must reach around supports, seam welds and penetrations without trapping dust in finished surfaces. Blowdown, inspection and masking space should be close enough to prevent unnecessary rehandling.
Recovery And Exhaust For Large Shells
Large cylindrical parts can shed media unevenly as they rotate or move. Media reclaim, dust collection, exhaust and replacement air should be arranged around the actual support method and shop traffic.
- Provide diameter, length, weight and support details.
- Identify rotation, crane or cart handling methods.
- Share coating steps, masking needs and utility locations.
Service Space Around Heavy Fixtures
Rollers, saddles and staging fixtures can crowd mechanical equipment if access is not planned early. Fans, filters, reclaim components, lights, controls and duct cleanouts should remain serviceable.
Frequently asked questions
What matters when blasting tanks and vessels?
Diameter, length, supports, rotation method, nozzle locations, weld details, exhaust routing and media recovery all matter.
Can a blast room be planned around vessel rollers?
Yes. The room and reclaim system should be coordinated with roller height, loading direction, service clearance and operator access.
Why is make-up air reviewed with exhaust?
Exhaust removes air from the room, and make-up air helps maintain a workable pressure balance around the finishing area.
What should be ready before Double D Mechanical reviews the site?
Tank dimensions, fixture information, handling method, coating sequence, utility points, building clearances and photos of the area are helpful.
