‌Product Overview‌

Hisea Marine's flat type aluminum anodes, also known as plate anodes, are designed for cathodic protection scenarios where a large, flat surface area needs to be protected or where the anode must be mounted directly onto a broad steel substrate. Their simple, robust plate geometry facilitates easy welding and ensures excellent electrical contact and current distribution across the protected surface.

‌Key Features & Design Advantages‌

‌Large Contact Area:‌ The flat plate design maximizes the surface area in contact with the electrolyte, promoting efficient current output.

‌Direct & Robust Attachment:‌ Engineered for secure, permanent attachment via welding directly to the structure, eliminating the need for complex brackets or straps.

‌Uniform Current Distribution:‌ Ideal for protecting large, flat panels such as hull plates, bulkheads, or tank walls, providing even coverage.

‌Material:‌ Manufactured from high-performance aluminum-zinc-indium (Al-Zn-In) series alloys for optimal service in seawater.

‌Typical Applications‌
Flat type anodes are commonly used in:

‌Ship Hull Plating:‌ Especially on flat sections of the outer hull or internal bulkheads.

‌Ballast Water Tanks and Void Spaces:‌ Where large internal surfaces require protection.

‌Offshore Platform Legs and Bracings:‌ For submerged or splash zone protection on flat structural members.

‌Water Tank Interiors.‌

‌Other large, flat steel structures‌ exposed to seawater or brackish water.

Mounting and Fixing

Welding Methods: Arc Welding

Arc welding: the most common welding method, guaranteeing a good mechanical and electrical connection.

Spot welding: for small or thin anodes for quick installation.

Installation Procedures

Surface cleaning: the surface of the structure to be protected must be thoroughly cleaned to ensure that it is free of oxides and contaminants.

Positioning of the anode: Precise positioning to ensure optimum current distribution.

Welding fixation: The anode is welded so that it is firmly attached to the surface of the structure.
