Rally discussed the unit heat exchangers with the Client to fully understand their previous issues and explore potential alterations. The team decided that converting the closure to a Kammprofile gasket-type design was the best way to eliminate the problematic diaphragm seal.
Rally worked with the Client’s preferred supplier to ensure that the new channel / bundle assembly would be 100% compatible with the existing exchanger shell, and fully compliant with modern pressure equipment codes.
3D modeling helped the team to visualize construction work, minimizing the removal of adjacent piping and structures.
A material requisition was developed for a new tube bundle and channel assembly; it contained all the specifications for design, metallurgy, fabrication, and shop inspection.
Rally arranged for the new Kammprofile gasketed channel cover to be installed and pre-tensioned prior to shipping. This saved the Client valuable time during the plant turnaround.
