The annual inspection of the petrochemical plant revealed that SS 304 tubes at Intercooler CO2 Compressor have failed. Some heat exchanger tubes were found during inspection with circumferential cracks. Some analysis methods were performed to investigate heat exchanger tube failures, such as X-Ray diffraction analysis, XRF (X-ray fluorescence) analysis, hardness test, morphology analysis, and numerical analysis. Investigation results revealed that pitting corrosion has been found on the inner surface of the tube that an essential factor in initiating cracks. Moreover, some porosities were observed spread distributed on the surface sample, which is believed to reduce the mechanical and physical value of the material. The corrosion and the fact that cracks were initiated in the relatively small tensile loads sites suggest that the component failure resulted from chloride-induced stress corrosion cracking. Investigation results for heat exchanger parameters, chloride content, and temperature operation have become the main factor in initiating chloride stress corrosion cracking (CSCC). The operational condition of the heat exchanger should not be referred to by the tube material austenitic SS 304. Regarding the systems with SS 304 tube heat exchangers and chloride content
