Rohner for Storage Tanks and Pressure Vessels
Storage tanks and pressure vessels bring curved shells, nozzles, saddles, weld seams and coating access challenges into the finishing area. Rohner equipment in this category may include large-equipment paint booths, open-face booths, blast rooms, powder coating areas, curing ovens, make-up air and exhaust systems. Double D Mechanical installs, relocates and services the booth, air, exhaust, heater and utility connections that support these coating operations.

Shell Diameter And Rotating Space
Tank and vessel work should be reviewed for overall diameter, length, nozzle projection, support saddle height and whether the piece rotates during preparation or coating. Door openings, booth depth and aisle clearance need to fit the part and the equipment used to move it. Operators also need access around ends, seams and fittings without crowding exhaust plenums or wall panels.
Surface Prep Before Coating
Blast rooms and media recovery areas should be arranged so prepared vessels move toward coating without collecting dust or debris. Masking for flanges, manways and machined surfaces needs space near the transfer path. When coatings are applied in stages, the layout should allow inspection and touch-up without sending parts backward through dirty operations.
Exhaust, Heat And Intake Routes
Large vessel booths can require substantial exhaust and replacement air, especially when doors are wide and parts occupy much of the interior volume. Duct routes, intake openings, heater locations and utility drops should be coordinated with cranes, roof framing and nearby process equipment. Double D Mechanical can align equipment connections with the building conditions and the desired finishing sequence.
- Provide maximum vessel length, diameter, nozzle projection and support method.
- Identify coating steps, flash space, inspection points and any cure requirements.
- Show crane hooks, monorails, fork truck aisles and staging areas on the layout.
Access For Filters And Fans
Maintenance access should be planned before a tank booth is boxed in by platforms, cranes or storage lanes. Filters, fan assemblies, dampers, lights, controls, heaters and duct cleanouts should stay reachable during normal production. Relocations should include a careful look at existing duct sections, wall panels and utility terminations before the move is scheduled.
Frequently asked questions
What tank dimensions matter most for booth planning?
Length, diameter, saddle height, nozzle projection, rotation method and handling equipment all affect booth fit and operator access.
Why include lifting equipment in the layout review?
Cranes, hooks, spreader bars and fork trucks can change the required clearances around doors, ductwork, lights and staging lanes.
What should be ready before Double D Mechanical visits the site?
Have part dimensions, proposed booth location, utility information, roof or wall penetration options, coating sequence and handling methods ready.
Can blast and coating equipment share one production lane?
They can be arranged in one flow, but dust control, media recovery, clean transfer and masking space should be planned carefully.
Which service points should stay accessible?
Filters, fans, dampers, heaters, lights, control panels, door hardware and duct access points should remain practical to reach.
