771 tubes – 2 pass Vertical Heat Exchanger
3” O.D. x 10 BWG (0.134” Min. wall) Nickel 200 tubes
Extreme erosion/tube wall loss on 2nd pass tube inlets hampered reliability resulting in 42 tubes being plugged.
CTI installed 324 Shield/Seals constructed from Nickel 200, 12 inches long to fit the existing 3” OD x 10 BWG tubes. The erosion was severe but only limited to the first 6-8 inches of the tube ID’s at the upper tubesheet. The foot long Shield/Seals reinforced the damaged tubes and improved reliability of the Evaporator.
