1. Introduction of my company (chromium) high silicon cast iron anode in strict accordance with ASTM A518 BS1591 standard GB8491-87 "high silicon corrosion casting" manufacturing. High silicon cast iron anode tube is made using centrifugal casting process, uniform thickness, pressure, central tube cable connection. Heart anode rod is a traditional sand casting, wiring cable linking to the anode side. This product is widely used in cathodic protection offshore drilling platforms, underground steel pipeline, oil joint stations, underground cables, underground storage tanks and other facilities in the applied current. 2.
