We supply standard anode sizes and can fabricate special steel moulds to meet customer requirements for use on platforms, pilelines, jetties and ships.

The anodes we supply are manufactured to the highest metallurgical specification and subject to the best quality control in the industry. Each batch is sampled before the anodes are cast. These samples are then subjected to spectrographic analysis to ensure it meets the specification.

Anode Alloys

Galvalum III

Aluminium-based alloy developed by Dow Chemicals in the US. This is recognised in the as the best alloy for sacrificial anodes for many applications.

This alloy uses indium as an activator, instead of mercury, and is therefore more environmentally friendly. It is also more tolerant of heat, having proven satisfactory protection for pipelines up to 100 deg C.

Galvalum III has worked well in oilfield brine treatment equipment operating in 15 per cent sodium chloride at 75 deg C as well as open seawater and saline mud.

AIL III

Widely used in the oil industry, AIL III uses indium as an activator but with considerably lower impurity percentages. The copper content has been reduced from a maximum of 0.006 to 0.002 per cent and iron from a maximum of 0.12 to 0.07 per cent.

AIL III has received type approval from DNV.
