Webwater, rate of heating, pressure varia tions, and the introduction of galvanic couples by the use of brass or copper pipe or fittings. One of the factors controlling the corrosion rate is the depolarization of the cathode by dis solved oxygen. The amount of oxy gen introduced into the hot water stor age tank will be in proportion to the WebAdding corrosion inhibitor to the environment. If these measures are not practical, the rate of attack can be minimised by keeping the anode to cathode area large, i.e. over 10. Alternatively, the anode could be designed with an appropriate corrosion allowance. Galvanic action can cause preferential corrosion of welds in
