Corpus Christi West Plant
Corpus Christi, TX
SA179 Carbon Steel finned tubes
242 tubes per unit (total 726)
1” OD x .134” Min Wall x 30’ long
Iris exam revealed ID pitting so severe that the units were unsuitable to be placed back in service without replacement or restoration. Completion of TAR and related unit startup could not be achieved until repairs were completed.
Installation of 726 Hastelloy C-276 Full Length Tube Liners™ to be purchased and installed on an “Expedited Basis”. The PO# was issued on 2/14/14 and the material was delivered to the site within 9 days (typically 8-10 weeks). In the interim, the units were removed from the Refinery and sent to a local fabrication shop for high pressure water lancing followed by a grit blast of the tube ID’s. The CTI crew arrived on 2/20/14 and completed the entire installation on all 3 units working back-to-back 12 hour shifts in 4 days thereby meeting the original start-up schedule.
