Case Study- Shell and Tube Heat Exchanger Refurbishment

InKorr were approached to perform a Shell and Tube Heat Exchanger repair, we arranged a meeting at site for an inspection and to discuss the required works, including decommissioning, removal from site, full heat exchanger refurbishment, replacement parts, testing, reinstallation & recommissioning. 

With our quote accepted, our service team removed the unit and brought it back to our workshop where  we carried out an initial inspection including leak test and disassembly to assess the internal condition. The testing found leaks at the tube bundle seals. Full disassembly of the unit revealed both the Shell and the tubes circuits of the unit were heavily fouled as seen below.

While the heat exchanger cleaning was being completed, new bolt sets, custom gaskets and new insulation was organized for the reassembly of the unit.

With the unit all clean, we reassembled and performed pressure tests on both circuits of the exchanger. 

New insulation and the casings were installed and the unit was readied for transport back to site.

InKorr returned to site with the refurbished unit, re-installed and connected up to its process, and then assisted the client with recommissioning the unit and observing its performance, to which our client exclaimed “I’ve never seen the unit heat up the oil bath so quickly!”
