Cylindrical high silicon cast iron anode

Scope of application

Applied to the impressed current cathodic protection of offshore drilling platforms, underground steel pipelines, combined oil production stations, underground cables, underground storage tanks and other facilities.

The pre-packed high silicon cast iron anode body is mainly composed of (containing chromium) high silicon cast iron anode, coke packing, guide pipe and steel casing, etc. The anode body usually ф 50mm×1500mm or ф 75mm×1500mm high silicon cast iron anode, and then the high silicon cast iron anode body is fixed in the center of the steel casing with a support. After installing the airway, the coke packing is filled around it. The operation that was carried out on the construction site is completed in the factory, which greatly reduces the working time on the construction site, simplifies the construction procedure, improves the work efficiency, and effectively ensures the construction and installation quality of the anode ground bed.

High silicon cast iron anode bed is one of the most common anode bed, zhongheng potentiometer impressed current cathodic protection system will after ac power rectifier dc power supply, the positive by auxiliary anode bed of the potentiostat will spread current into the earth, auxiliary anode bed construction quality determines the overall quality of cathodic protection system and the protection efficiency. Strict management is needed in the design and construction of cathodic protection system.
