T BAILEY INC.’s Shop-Built Tank Fabrication Process

As soon as T BAILEY INC.’s design engineers finish modeling your shop assembled tank, the design is passed on to our fabrication division. Shop-built tank fabrication is normally completed in these steps:

  1. Use CNC plasma cutters to cut out and etch the steel plate.
  2. Beveling of the weld seams as needed to provide a quality weld.
  3. Transform the plate into cylinders by passing it through rolling machines.
  4. Weld the longitudinal seam of the cylinder.
  5. Weld on one head and join the cylinders to create the tank shell.
  6. Attach the final head to the shop-built tank using single or tandem head welding manipulators.
  7. If required, install nozzles in the tank’s shell.
  8. Attach additional hardware, lifting devices, or structural supports.
  9. If needed, create and attach platforms, ladders, and other accessories.
  10. Forward the tank to T BAILEY INC.’s testing division, where the completed shop-built tank will have to pass rigorous testing and quality control
  11. T BAILEY’s paint division completes the product with all painting and coating requirements before being shipped to the customer.

AISC Painting & Blasting For Shop-Built Tanks

What sets T BAILEY INC. apart from the competition is that we are able to perform every step of the shop-built tank fabrication process in-house — including painting and blasting.

Our process-driven professionals will protect the integrity of your shop assembled tank by beginning the painting process in the first stages of fabrication and continuing until the tank’s completion. This ensures that you receive a shop-built tank built to resist corrosion and able to last for many years.

Our AISC painting and blasting services include:

  • Prewashing the steel to eliminate soluble salt, oil, and other contaminants per SSPC SP1.
  • Prepping the steel for coating by machine or manual blasting.
  • Metalizing the tank with aluminum or zinc.
  • Lastly, we prime and finish the coating and lining with epoxies, urethanes, zinc, enamels, and vinyl ester coatings.

Because we have our own industrial coating division in-house, you can save thousands of dollars on painting and blasting fees by working with T BAILEY INC.
