Product Description
Magnesium Sacrificial Anode - Marine & Pipeline Cathodic Protection
The Magnesium Sacrificial Anode is a high-performance cathodic protection solution for marine structures, underground pipelines, and storage tanks. Factory-direct manufactured with AZ63 magnesium alloy and prepackaged with specialized chemical backfill for optimal performance. Backed by years of proven US market export expertise and competitive bulk pricing.
Key Features
- Superior Anti-Corrosion Performance: AZ63 magnesium alloy with high driving potential (-1.5V to -1.6V vs Cu/CuSO4) delivers consistent cathodic protection current in both freshwater and soil environments, effectively preventing galvanic corrosion on steel structures.
- Prepackaged Design: Each anode comes sealed in a cotton bag with premixed chemical backfill (75% gypsum, 20% bentonite, 5% sodium sulfate) that retains moisture, reduces ground resistance, and ensures uniform consumption of the anode over its service life.
- Competitive US Export Pricing: As a direct manufacturer with established US market logistics, we offer competitive FOB and CIF pricing for bulk pipeline projects and wholesale distributors—with no middleman markup.
- Proven US Market Track Record: Regular export shipments to US Gulf Coast, West Coast, and Great Lakes regions with full ASTM compliance documentation, material traceability, and third-party electrochemical performance testing accepted by US engineering firms.
- Versatile Installation: Suitable for buried pipelines, dock pilings, ship hulls, ballast tanks, offshore platforms, and underground storage tanks with customizable lead wire lengths and connection types.
