Heat Exchangers






Our team has analyzed the failure of many different types of heat exchangers including cooling systems for electrial, pharmaceutical and chemical equipment. The equipment examined included spiral and plate finned tube heat exchangers, ISO 9001 designs of all-Aluminum heat exchangers, gasketed plat, fully welded, semi welded plate and brazed plate heat exchangers. We have also worked on fully welded counter flow plate heat exchangers constructed of a variety of high temperature alloys for tempertures up to 1200 degree F and pressure differentials capability of up to 5 PSI. The list of exchangers exmamined further includes ASME certified, "U", "UM", and "R" designs for areospace, chemical, pharmaceutical, food, pulp, power and petrochemical industries.

The drawing to the left shows a case where tubes were rolled incorrectly onto the tube sheet, resulting in malfunctioning of the heat exchanger. The photo shows the analysis our engineers performed on the tube sheet, demonstrating the areas of greatest weakness.
