Thermally Sprayed Aluminium (TSA) for corrosion resistance

Corrosion of steel components in an offshore environment is an ongoing major issue for those companies who manufacture and supply the oil and gas industry with structural steelwork. The steelwork can be anything from a walkway between two sections of a platform to the riser pipes that come up to the ocean’s surface from the seabed. The size of the steelwork tends to be on the large side though Impreglon has yet to be presented with a component too large to handle.

There are many coatings within the Impreglon range that will give long term corrosion resistance but a key coating the oil and gas industry use is Thermally Sprayed Aluminium – known as TSA. TSA is 99.5%+ pure Aluminium wire that is arc sprayed into the steel. The benefit of TSA when applied to steel is that the Aluminium will corrode in preference to the steel should the coating ever be damaged down to the steel. This property is known as galvanic corrosion. The TSA is also usually sealed with either an epoxy or silicone.

Impreglon is not only an experienced applicator of TSA but is renowned for its quick turnaround capability, service and quality. Recent projects have included work for the Kizomba, Blackbird and Goliat oilfields.

Impreglon UK is part of a worldwide group of companies specializing in surface protection for applications where non-stick, corrosion protection, traction, hard facing and dry lubrication properties are required. If necessary a coating can be tailor made to help solve specific problems.  In addition to our PlasmaCoat systems we offer a complete range of Teflon^® and Xylan^® fluoropolymer coatings.
