    摘要: A method of applying a liquid coating material to the inside of a tank(10) and performing a hydrostatic pressure test on the tank at the same time. The method is useable for applying a liquid vitreous enamel coating material to a water heater tank, to be subsequently dried and furnace heated to form a glazed enamel internal coating. Preferably the hydrostatic pressure test is performed by displacing coating material from a portion(68) of an accumulator(51) by pumping liquid into a flexible bladder(66) housed in the accumulator. Pressure from pump(76) is transmitted to the tank(10 by the liquid coating material and held for a prescribed time interval to prove tank integrity. The method avoids excessive shear, hence viscosity changes in thixotropic coating materials.
