Forensic Examination of Rubber Expansion Joint Project objective An expansion joint made of silicone rubber was used in an incinerator system. The expansion joint was located between two stainless steel pipes and was secured using band clamps. The expansion joint was used on the incinerator stack, which was the exit pathway of the incinerator flue gas with known composition including hydrogen chloride. The temperature and pressure of the flue gas was approximately 173 °C and 14.6 psia, respectively. During the inspection, some cracks were observed on the expansion joint which resulted in its premature failure. The project objective was to determine the failure mechanism and the probable cause of failure. Scope of work The scope of work was to perform a detailed analysis to discover the roo
