Coating Pipe Spools and Rack Steel in Indiana Energy Module Shops
Before an LNG or energy module is assembled, its pipe spools, rack beams and support steel are fabricated and coated as individual pieces. Indiana shops feeding module programs often coat long, slender parts by the hundreds: spools with flanges and branches, beams with clip angles and supports with odd shapes. Long parts and high piece counts call for a different finishing setup than a single large module. Double D Mechanical installs, relocates and services the booths, ovens, exhaust and make-up air for that kind of work.
Discuss your installationLength Sets the Booth
A spool or beam has to fit in the cabin with room for a painter at each end. Long booths, end-door or pass-through layouts and racks that hold several pieces at once let a shop coat more steel per cycle.
- Longest spool or beam in the program
- Number of pieces per rack or cart
- End-door or side-door loading
- Room for painters at both ends
Turning Parts for Full Coverage
Spools have flange faces, branch connections and undersides that are hard to reach. Rotators, turning stands or racks that allow parts to be flipped between passes help painters cover every surface without handling wet steel.
Airflow Over Long Slender Parts
Long parts spread across the cabin can block crossdraft air near the floor. Rack height, spacing between pieces and exhaust filter placement should be considered together so overspray does not drift back onto coated sections.
Moving Coated Steel to Laydown
Coated spools and beams need somewhere to cure without being stacked or scratched. A heated cure area or covered laydown with racks protects the coating until it is ready to ship or go to assembly.
Planning a booth or oven project in Indiana
Crews mobilize from Houston; Indiana is roughly 850 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Indiana is concentrated around Indianapolis, Fort Wayne, Evansville, and South Bend. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive and powertrain, RV and trailer manufacturing, steel, and aerospace components.
Cold winters mean make-up air heaters are sized for sub-freezing intake, and booth or oven placement has to account for frost lines, snow loads on roof penetrations and winter slab work.
Frequently asked questions
How long should a booth be for pipe spools?
Longer than the longest spool plus working room at each end. Program drawings or a cut list give the length range to plan around.
Are rotators useful for spool coating?
Yes, they make it easier to reach flange faces, branches and undersides without lifting wet parts.
Can multiple spools be coated at once?
Yes, on racks or carts spaced so painters can reach all sides and airflow can move between pieces.
Where should coated spools cure?
In a heated cure area or covered laydown with racks that keep parts separated, so coatings are not scuffed before they are hard.
What information helps plan a spool coating line?
Spool length and diameter ranges, weights, pieces per week, coating system, handling equipment and the available space for booth, cure and laydown.
