Niles Steel Tank maintains a large selection of standard large-volume hot water storage tanks in inventory, which are available for quick ship. Inventory gallon sizes range from 210 gallon up to 1000 gallons. All tanks are vertical, glass lined with oxide primer. Manways are optional on 36 inch diameter and below. All bare vertical tanks come standard with lifting lugs. Each tank is hydro-tested and independently inspected as ASME regulations require. Niles Steel Tank’s Ultonium™ lining is applied to the interior surface of the steel providing a tough wear resistant lining that minimizes the effects of high temperature hot water.
