Description
Product Description:
High Silicon Tubular Anode Howah supply is used for impressed current cathodic protection systems in a wide variety of industrial applications. Silicon iron and silicon chromium iron alloy corrode relatively slowly. The low-cost anode material offers long life at an economical price. There are two different alloy grades: FeSi Alloy silicon iron anodes are used in neutral soils and fresh water. FeSiCr Alloy silicon iron anodes are used in aggressive acidic or alkaline soils and in sea-water environments.
Application of High Silicon Tubular anode
1. Deep well anode systems
2. Shallow anode installations
3. Offshore applications
