Component Repairs

TCT has in-house facilities to perform many Component Repair operations. Specifically for the Siemens Energy engine line, protective coatings are applied to both the internal and external components in order to minimize the detrimental effects of corrosion and erosion. The paints can be classified as a member of aluminium based corrosion resistant paints, stoving enamel grey, and dry film lubricants. A list of some of the paints that can be applied include PL101, PL163, PL165, PL205, PL237, PL239, Xylan 1010 (Teflon), Molykote D321R, Sermatel 570A, Sermatel 709, and Sermatel W. However, other coatings have been applied upon customer request.

In addition to masking, painting and curing operations, other capabilities of the Component Repair department include blending and polishing, TIG welding and glass bead blasting.
