Prophylactic inspection of
Heat exchanger tubes in fossil-fueled power plants are subject to corrosive and high mechanical stresses and are operated in the creep range. In order to avoid damage resulting from this, which usually leads to the plant being shut down, the condition of the heating surfaces is continuously monitored. In this context, VPC GmbH’s ISO 17025 accredited materials testing laboratory carried out comprehensive metallographic tests to assess the material condition of tube samples. The results enable the operator to estimate the remaining service life of the examined heating surfaces and to plan the necessary inspection/overhaul work.
