Abstract
A steel hot water tank (12) having a corrosion inhibiting coating
on the interior surfaces (34) of the tank is provided
with end portions (14, 16) each having concave interior surfaces. A
connecting device (54) is used to permit connection of a
precoated tank end to a precoated tank interior whereby the heat of
welding the tank end to the tank side wall does not
degrade the corrosion inhibiting coating of the tank interior. This
construction provides increased volume for the tank
compared to existing hot water tank constructions, and enables the use
of material thicknesses in the tank ends which may be
equal to or less than the material thicknesses of the tank side wall.
A process is provided which permits the welding of the
tank end to the tank side wall without degrading the corrosion
inhibiting coatings previously applied to the parts being
assembled.
