BAC Corrosion Control reports that it is introducing a new range of impressed current mixed metal oxide tubular anodes. The company believes that, by paying careful attention to design, it has been possible to set the cost of BAC's MMO anodes at a level that closely approaches that of equivalent silicon-iron and magnetite anodes. Also, due to their light weight and ease of installation the new anodes are said to eliminate the handling and application problems that exist when using the heavy and brittle alternatives.

Also available from the company are its ISOMAG and ISOROD extruded magnesium anodes which are manufactured from virgin magnesium alloys - no scrap - in 18 standard sizes. Weights range from 1.3kg to 27.3kg and cover the most common sizes currently in use for protecting pipelines and buried structures.

Pin brazing reportedly ensures a safe, fast and reliable electrical connection to different types of steel structures. The procedure is said to take only seconds and is thought to be ideal for joints between pipes, connections to measuring cables, installation of sacrificial anodes, test posts and many other applications.

Corrosion damage to the hull of any seagoing vessel is expensive to repair and frequently only detected at dry-docking. Impressed current cathodic protection (ICCP) systems can be monitored and have made corrosion protection much more controllable. BAGC Award systems are available to protect hulls, bow thrusters and water jet systems on fast ferries.
