Substation Structures and Equipment

Flow Coating TransformersFlow-Coating Transformers

The power transformer, as you know, is a vital and expensive piece of equipment in the substation. Proper maintenance of this piece of equipment, especially the cooling components are key to extending life expectancy, as well to maintain efficiency and reliability. We work with our customers to identify and implement the proper preparation and coating of the fin surface. The “Flow Coat” method is the most widely utilized process of insuring 100% coverage (including tubes, stabilize bars, joints and seams on the backside, etc..) of the radiator tubes. This method may be utilized to chemically clean and prepare the steel surface as well as applying paint materials. Other transformer surfaces will also be addressed using the most appropriate preparation methods and coating application procedures.

Public Utilities Maintenance is an SSPC QP1 (Field Application to Complex Industrial Structures), QP2 (Lead Paint Removal) certified painting contractor, and our Quality Management process is ISO 9001:2008 certified. Our management team will work with you to match the best flow coat equipment with the proper coating material for your equipment’s environment.
