TMI Performs Tube Sheet and Water Box Coating


TMI Coatings, Inc. (TMI) was awarded a contract with Colorado Springs Utilities to perform repairs, surface preparation, and coating application to two large condensers at the Martin Drake Power Plant located in Colorado. The tube sheet ends were heavily corroded due to the chemicals used in treating the water.

Before surface preparation and coating application, approximately 8,600 7/8” outside diameter stainless steel tube ends were precisely trimmed and flared flush with the tube sheet with specialty tooling. Nearly 17,200 sandblast plugs were firmly set before TMI sandblasting all surfaces of the tube sheets and water boxes to SSPC-SP10 / NACE No.2 Near White Blast. Following surface preparation, specialty coating plugs were precisely set in all 17,200 tube ends again before TMI applying a 200 mil 100% solids spray epoxy coating to all four tube sheets.
