Overview

O n WWI we are pioneers worldwide in the manufacture of sacrificial anodes only uses raw materials the best quality.

Our aluminum and zinc alloys are patented and registered for more than 50 years, our brands being a reference worldwide.

Our anodes are manufactured with raw materials of the highest quality and for this reason the life of our anodes is much longer than others.

We offer design, manufacture, install and service the shipping for Offshore & Onshore Industries.

Sacrificial Anodes

Aluminium Alloy

High Capacity Aluminum Sacrificial Anodes for ship build, ship repair, offshore renewable, oil & gas, port & harbour, and petrochemical industries.

Aluminum anodes from Wilson Walton (WWI Aloline® ) are cast in low-iron high efficiency aluminum alloys. WWI Aloline® anodes are characterized by lightweight and high amperage output.

This alloy was developed together with British Aluminum (BACO) the BA778S® aluminium alloys, over a long period during which their excellent performance characteristics was widely recognized. Evidence of this can be found in the number of WWI Aloline® anodes based systems installed on North Sea offshore structures and other places.

Sacrificial Anodes

Features & Benefits

  • Improved Corrosion Protection is provided by Aloline’s higher driving potential compared to zinc or aluminum/mercury alloys.
  • Lower Cost per System is achieved because Aloline’s greater efficiency means fewer anodes are needed, saving on material and installation labor costs.
  • Optimal Composition, Quality & Fit is ensured with anodes designed and manufactured at Wilson Walton’s own foundry.
  • Bulk Melter enables the production of anodes in excess of 700Kg, other weights, consult.
  • Purity Matters. Contaminants like iron reduce anode life and effectiveness. Aloline alloys are the purest available, offering exceptional corrosion protection:

    - P0404 Alloy – the purest, premium low-iron aluminum alloy for offshore structures and other applications demanding high performance and extended anode life. Contains MAX 0.04% silicon and 0.04% iron.

    - P0506 & P0610 Alloys – low-iron aluminum alloys offering superior performance for most marine applications. P0506 contains MAX 0.05% silicon and 0.06% iron. P0610 contains MAX 0.06% silicon and 0.10% iron.
  • The order of 3.4 times the electric capacity on the zinc, which is reduced by the same proportion the anode mass to the same surface.
  • Light specific weight.
  • High electrical capacity –2700 ampere hours per kilogram.
  • High solution potential –1100 mV negative to a Ag/AgCI seawater reference cell.
  • Even corrosion pattern without fissuring.
  • Stability of composition and performance during storage and service.

WWI´s anodes are manufacture under conditions of a stringent quality control conforming to ISO9001. All alloy cast are made from High Purity Ingots of grade 99,40% minimum, alloyed to ensure even corrosion pattern, reliable electrical efficiency and a long working life.

Installation & Operation

Aluminum anodes WWI Aloline® are normally clamped or welded into position from an integrated steel core. Aluminum Anodes can be installed by customer maintenance personnel in accordance with Wilson Walton-supplied layout drawings.

With proper installation, WWI Aloline® anodes will operate efficiently and economically without attention. They generate their own current and work silently and surely to control corrosion. Apart from routine inspection, no labor costs are involved after installation and no electrical supply is required.




Zinc Alloy

Zinc Anodes for Shipping, Offshore & Onshore Industries.

Zinc anodes, (WWI Zincoline® ) are cast in current U.S. Military Specification (Mil-Spec) and Special High Grade high purity alloys. Zincoline anodes are the ideal corrosion protection solution where the use of aluminum anodes is restricted, as in the upper areas of tanks.

Sacrificial Anodes

Features & Benefits

  • Economical and Time-Tested, Zincoline® anodes set the standard for affordable corrosion protection.
  • Optimal Composition, Quality & Fit is ensured with anodes designed and manufactured at Wilson Walton’s own foundry.
  • Comprehensive Range of hull, tank, engine room, bracelet and other anodes is available to suit virtually every marine application.
  • Pit-Guard Anodes stop corrosive pitting in cargo and ballast tanks simply and economically.
  • Zincoline Alloys include the latest Mil-Spec delivering trusted performance, as well as Special High Grade (SHG) for reliable protection wherever Mil-Spec is not required.
  • Immediate Delivery of large quantities of standard anodes is available from stock.
  • Custom Zinc Anodes can be produced to satisfy unique specifications.
  • Electrical capacity – 780 ampere hours per kilogram.
  • Solution potential –1050 mV negative to a Ag/AgCI seawater reference cell.

Installation & Operation

Zinc Anodes, WWI Zincoline® are normally clamped or welded into position from an integrated steel core. Zinc Anodes can be installed by shipboard maintenance personnel in accordance with Wilson Walton-supplied layout drawings.

With proper installation, WWI Zincoline® anodes will operate efficiently and economically without attention. They generate their own current and work silently and surely to control corrosion. Apart from routine inspection, no labor costs are involved after installation and no electrical supply is required.
