Adamson can supply tanks painted in accordance with virtually any industrial, military, or civilian painting specification. All Adamson tanks, unless protection is otherwise specified, receive an industrial shop coat prior to shipment.


Galvanizing has been used as a corrosion deterrent for steel water tanks for many years and has given satisfactory results in thousands of cold water installations. Although the protection cannot be considered as permanent as that of cement or epoxy lining, and is not suitable for extended operation much in excess of 100 F, galvanizing does extend that tank life considerably at a reasonable cost.

Dura-Flex-Cement Lining

Cement lining is applied to the interior of steel pressure vessels to provide protection against corrosion. The Adamson Dura-Flex cement lining is designed to develop a high strength bond between the tank and the lining and to safely withstand handling during shipment and installation. The lining imparts no odor or taste to water and will withstand temperatures up to 212 F.


Epoxy linings are one of the modern alternatives to glass lining and phenolic lining. They have been widely accepted and have provided excellent results in eliminating corrosion in steel vessels containing water or other liquids.


This is a two part system consisting of Dura-flex undercoat covered with a solvent free two-component heavily cross-linked polymerized topcoat which will provide a hard, durable, nontoxic inert finish. This coating conforms to AWWA, USDA, FDA and, if required, NSF standards for potable water and is unaffected at temperatures up to
200 F (tested at 73.4 F for NSF).


These tanks are constructed so that the tank contents contact only non-ferrous surfaces. To accomplish this, the 3# per square foot sheet copper lining is electrically welded to the steel tank at every seam of the lining and at every connection and opening. Every connection and opening is electrically welded to the outer steel shell. Thus, the lining is strongly and permanently attached to the outer reinforcing shell, the surface of which is completely sealed off from corrosion forming air and water. The result is a copper tank constructed inside of, and reinforced by a steel outer tank effectively giving a double walled construction. An inspection opening is provided to monitor the interstitial space and detect any leak in the inner copper shell without removing the vessel from service.
All threaded connections are of extra heavy solid copper nickel material.

The neck portions of all flanged nozzles and element necks are constructed of solid copper nickel; these are welded to steel flanges in such a way that gasket surfaces are also of copper nickel.
The manhole ring is copper-lined and the cover is solid copper nickel.
All tube-sheets, spacers and supports of elements are of solid bronze.

For storage heaters, the element, the lining and the steel tank are tested independently of each other, to prevent possibility of “hidden” leaks in either the element or the lining.


This is a two component, instant setting polyurethane developed to protect potable water tanks. It will not impart any taste to the contents of the tank and is approved for contact with potable water by various authorities. Urethane can only be applied to tanks 60″ in diameter and larger with no internal trim.


A complete line of Adamson welded steel supports is available. The three most commonly used pressure vessel supports are: angle legs or base rings for vertical tanks and saddles for horizontal tanks. Saddles can be supplied with threaded bosses for pipe legs.
