Tank Products
























Waterford Tank’s Gunbarrel tanks are an economical and low maintenance method to treat oil when properly applied. These tanks are an excellent choice when adequate separation of oil and water is required and uses atmospheric pressure, gravitational force and retention time. Production fluids enter the inlet down-comer section at the top of the tank. Solution gas is vented from the top of the flume and directed to a vapor recovery system or vapor combustion tower.


Waterford Tank’s Gunbarrel tanks have down-comer pipe assembly up to 12” with support bracing, spreader table, water and oil outlets.  Waterford Tank’s Gunbarrel tanks come with fittings up to 6” NPT and flanged connections up to 12”, 24” x 36” cleanouts, 8” thief hatch, and optional 8” or 12” EPRV.  Waterford Tank manufactures Gunbarrel tanks ranging in size from 210BBL to 1000BBL.
