A molasses pipe bridge was experiencing excessive corrosion; TMI Coatings, Inc. (TMI) received a contract to prepare the surface, prime, and topcoat the pipe bridge at a yeast facility in Tennessee. The structural steel components over the years had corrosion present due to the harsh environments of proximity to the Mississippi River. With the help of the company engineering staff, TMI devised a plan to complete this work with minimal interruption to the companies daily processes.
- TMI protected all sensitive equipment with poly from any overspray; those items include conduit, piping, and other miscellaneous components.
- Next, TMI pressure washed all the structural steel with 4,000 psi pressure washers. In a couple of areas, we brush blasted the steel to remove any loose, peeling paint. We hand tool cleaned numerous areas without coating or rust before coating.
- TMI then applied a full coat of rust-inhibitive epoxy primer suitable for high performance on new and old steel.
- Finally, TMI top coated the entire pipe bridge with a gloss aliphatic polyurethane topcoat.
The system TMI recommended had outstanding weather resistance with excellent gloss and color retention. After the job, the contact stated, “I just wanted to let you know Tim (our Foreman) did a great job on the pipe bridge; he is a very good man.”
