The Problem
Heat exchanger rebuild; This sugar mill needed a solution for their press water heater. The area around the tubes had a ¼” to ½” of missing metal on the faceplate of the heater and was getting worse.
They asked the USI Team for a solution to rebuild and protect it so they didn’t have to pay to replace this unit.
The Substrate
Metal
The Solution
For this heat exchanger rebuild USI put together a plan.
First, the area was cleaned with USI Universal Cleaner this solvent cleaner is fantastic at removing and imbedded grease, oil or impurities found in the water this heat exchanger was heating.
Next, the MBX Bristle Blaster was used to create a 2 ½” – 3” anchor pattern around the tubes where there was missing metal.
Then the USI Team used RES201 Ceramic Repair Paste to build up the areas around the tubes.
After allowing cure time for this material, 2 coats of RES205 Ceramic HT Fluid was applied. This product is designed for up to 300°F continuous immersion.
