‌Introduction & Core Value Proposition‌

Magnesium alloy sacrificial anodes from Hisea Marine are engineered to deliver the highest driving voltage among common sacrificial anode materials, making them the premier choice for cathodic protection in high-resistivity environments such as soil and fresh water. Their active corrosion provides robust, maintenance-free defense for buried assets, storage tanks, and water structures.

‌Why Choose Magnesium Alloy Anodes?‌

‌Highest Driving Potential:‌ Delivers a powerful protective current, ensuring effective polarization even in challenging, high-resistance conditions.

‌Ideal for Soil & Freshwater:‌ The material of choice for underground pipelines, tank bottoms, and freshwater systems where aluminum or zinc are less effective.

‌High Current Output Per Unit Weight:‌ Offers efficient protection with a favorable cost-to-performance ratio.

‌Self-Powered & Reliable:‌ Operates automatically without any external power source or monitoring systems.

‌Our Magnesium Alloy Anode Product Range‌
Hisea offers a complete portfolio of magnesium alloy anodes to meet diverse project requirements:

‌High Potential Magnesium Alloy Sacrificial Anode‌

‌Primary Use:‌ Critical protection for buried pipelines and structures in dry or rocky soils.

‌Bracelet Magnesium Alloy Sacrificial Anode‌

‌Description:‌ Cast in a semi-cylindrical “bracelet” shape for direct attachment to pipelines.

‌Primary Use:‌ Cathodic protection for submerged or buried pipelines, ensuring uniform current distribution.

‌Magnesium Alloy Sacrificial Anode Set Assembly‌

‌Description:‌ Pre-assembled units including anode, cable, and sometimes backfill, ready for installation.

‌Primary Use:‌ Simplifies and accelerates field installation for various grounding and protection projects.

‌Strip Magnesium Alloy Sacrificial Anode‌

‌Description:‌ Flexible, extruded ribbon anode that can be bent and shaped.

‌Primary Use:‌ Protection in confined spaces, tank bottoms, or for long-distance pipeline casings.

‌Magnesium Alloy Sacrificial Anode for Buried Pipeline‌

‌Description:‌ Anodes specifically engineered and sized for the long-term protection of buried transmission pipelines.

‌Primary Use:‌ Oil, gas, and water pipeline networks.

‌Magnesium Alloy Sacrificial Anode for Natural Gas Pipeline‌

‌Description:‌ Designed to meet the specific safety and performance standards of the natural gas industry.

‌Primary Use:‌ Cathodic protection systems for natural gas transmission and distribution pipelines.

‌Magnesium Alloy Sacrificial Anode for Outer Wall of Storage Tank‌

‌Description:‌ Anodes configured to protect the external bottom and walls of above-ground storage tanks (ASTs) from soil-side corrosion.

‌Primary Use:‌ Tank farms for crude oil, petroleum products, and water.

‌Magnesium Alloy Rod‌

‌Description:‌ Cylindrical rod anodes, available in various diameters and lengths.

‌Primary Use:‌ Deep well anode groundbeds or inserted into specific structures for localized protection.

Features

Magnesium is characterised by small density, very negative potential, low polarisation rate, large amount of electricity generated per unit mass, which is an ideal sacrificial anode material. Magnesium sacrificial anode magnesium alloy anode mainly has magnesium-manganese alloy, magnesium-aluminium-zinc-manganese alloy two categories, the former is also known as high potential magnesium anode, the latter is mainly used for the production of cathodic protection of buried steel pipelines and the protection of the inner liner of electric water heaters.
