Canistered High Silicon Cast Iron Anode

Name: Canistered High Silicon Cast Iron Anode
Brand: BaiQi Metal
Availability: InStock
Rating: 5 (1 reviews)

BaiQi’s Canistered HSCI Anode: Galvanized steel can with calcined coke backfill for cathodic protection. Casing corrodes fast post-install—ideal for buried/subsea use.BaiQi’s canistered anode features a tubular or stick-type high silicon cast iron anode securely pre-packaged within a large spirally wound galvanized mild steel can, filled with calcined petroleum coke backfill. The canister casing is designed solely to withstand transportation and installation. Upon installation, the outer casing becomes part of the anode system and is engineered to corrode rapidly, leaving the anode and coke backfill intact.
