Zinc Anode 330 Datasheet ^new^ | Authentic & Authentic
If you work in marine engineering, HVAC, or cathodic protection, you’ve likely encountered the term . While “330” is not a universal standard (like MIL-SPEC), it most commonly refers to a hull-mounted, rectangular zinc anode weighing approximately 33 lbs (15 kg) – with the number indicating its approximate length in millimeters or a legacy model code.
300 mm (Length) x 80 mm (Width) x 40 mm (Thickness) — typical configuration variations exist based on core selection. Primary Applications Marine Vessels Protection of ship hulls, rudders, and bilge spaces. Corrosive defense for ballast tanks and sea chests. Preservation of propeller shafts and thruster tunnels. Offshore Infrastructure Cathodic protection for oil and gas jacket platforms. Corrosion mitigation for subsea pipelines and risers. Structural defense for harbor piling, docks, and jetties. Industrial Systems Internal protection for heat exchangers and condensers. zinc anode 330 datasheet

is a high-build, two-component, inorganic zinc-rich alkyl silicate primer designed to provide long-term cathodic protection for steel in highly corrosive environments . It conforms to SSPC Paint 20 Level 1 standards, containing at least 85% zinc in the dry film. Technical Specifications Offshore Infrastructure Cathodic protection for oil and gas
This article provides an exhaustive breakdown of the Zinc Anode 330 datasheet—covering chemical composition, electrochemical properties, dimensional tolerances, weight calculations, and real-world installation best practices.
Formulated with high levels of metallic zinc to inhibit corrosion by acting as a sacrificial anode for the steel substrate. Durability:
