A solution to corrosion C orrosion caused by seawater is a troublesome problem in marine industry. Several attempts have been made to solve the problem including metal alloys, electronic protection, polymeric materials and corrosion proof coatings. Most of the options have introduced new problems, such as electro chemical corrosion typical to metals. Polymeric materials increase the amount of flammable materials in ships and the life cycles of most coatings are not sufficient. The Finnish companies, Teknikum and YIT Teollisuus ja verkkopalvelut, have been delivering rubber coated steel pipes in cooperation. The pipes are designed to fit the purpose of use. The deliveries have been supplied around the world for over 20 years. The most typical destinations are the seawater pipes of ships and oil rigs. Coal and nuclear power stations located by the sea have also become important users of the pipes. The same production technology has been applied successfully in mining industry as well. ■ More information: www.teknikum.com 22 seatec 2/2008
