Description

Description Aluminum anodes have long been used in the fight against corrosion. In the oil and gas industry, aluminum anodes are widely used to protect against corrosion in a wide variety of steel structures such as oil-water separators, condensers, tanks and any other vessel where produced water is stored. Common installation methods include welding or bolting the anodes directly to the structure that is to be protected. ALOLINE aluminum anodes are designed for optimum performance under a variety of environmental conditions and temperature ranges. Cast in different sizes and weights, ALOLINE anodes provide maximum performance in seawater and brackish environments.Typical Chemical Composition Element Percentage Indium (In) Zinc (Zn) Silicon (Si) Copper (Cu) Iron (Fe) Cadmium (Cd) Others, each Others, total Aluminum 0.016 to 0.02% 4.75 to 5.75% 0.08 to 0.12% 0.003% Maximum 0.12% Maximum 0.002% Maximum 0.02% Maximum 0.05% Maximum Remainder Performance Characteristics Anode Capacity Potential (Calomel) Consumption Rate 1150 amp hours per pound (Minimum) 1.080 volts (Minimum) 7.6 pounds per amp year Available Sizes Aluminum anodes are available in many different shapes, weights, and core configurations. While many of these configurations are listed in the following charts, many more anodes are available but not shown.
