Heat exchanger tube bundle inspection
Aug 04, 2020

For heat exchanger, bundle inspection is the most difficult, but its importance can not be underestimated. In the process of practical application, heat exchanger tube bundles are easy to be affected by the medium, or material problems and form stress corrosion, intergranular corrosion, pitting corrosion and fatigue corrosion, etc. In view of this situation, it is necessary to check by means of pressure test, so as to understand the leakage situation and specific location of the heat exchanger. If the problem of corrosion and perforation occurs in the tube of heat exchanger, it is easy to cause serious leakage problem, which will bring negative impact on the production of the device itself. If this type of failure occurs in the heat exchanger, the cost of replacing the tube core is relatively high, so the original tube core should be extracted and the installation of new tube core should be completed.
