Due to presence of ‘turbulator’ strips (twisted strips inside each tube to increase the turbulence flow of the exchanger) of the heat exchanger tubes, the original scope was reduced to avoid such delay in inspection time. Inspection, analysis and reporting done and given to client for further action.

​

• Petron Bataan, Phillipines 2016 (Tube Inspection- IRIS) December 2016

The corrosion occurs due to the turbulence and temperature change at the inlet section of the air finned coolers. Initially, the client applied anti-corrosion sleeves yet the sleeves length was not sufficient enough to protect the tubes (wall loss was detected approximately 100mm after tube lips). Inspection, analysis and reports given to client for further action.
