Description
ZINC ANODE WELD-ON 390x155x36MM
Product Overview :
Hull Anodes provide cathodic protection in varying marine environments such as salt water, freshwater, and brackish water. Our sacrificial anodes conform to the highest Mil-Spec standards and come in a variety of shapes and sizes. Depending on the type of metal and water we offer zinc, aluminum, and magnesium galvanic anodes for all of your underwater cathodic protection needs.
Zinc Anode Weld-on 390x155x36mm are recommended on vessels where a long life span is required or where the anodes are subject to significant vibration, agitation, abrasion or other physical impact. To ensure continuity and a 100% secure fixing, welded anodes are best.
The welding strap is commonly cast in steel core to the anode for easy fixing. It also has the added advantage of turning into a bolt on anode if you wished to drill your own bolt holes at bespoke bolt center.
Key Features
- Weld-on installation with galvanized steel straps
- Streamlined shape for less resistance
- Provides cathodic protection
- Meets or exceeds US Military Specification (MIL-A-18001K)
- For use in Salt Water
Installation
The anode must be in direct contact with the metal it protects : never paint around an anode or the anode itself.
When Should Anodes Be Replaced ?
Anodes deterioration rate may fluctuate according to the mooring area, water salinity, PH and temperature, potential electrical failure on board, and of course, the quality of the anodes themselves.
A good benchmark for replacement is when the anode is 70-80 % dissolved. We recommend to replace anodes every year when doing the boat antifouling/launching. In all cases, anodes deterioration should always be watched carefully together with the condition of the metal parts they protect.
On the opposite, anodes may dissolve quickly if they are bad quality or if there is an electrical failure on.
