Tube vibration is a leading cause of tube leaks. Tube seal weld cracks and tubesheet cracks are also main sources. As a result, leaks can occur on individual tubes, entire rows or regions within the heat exchanger and cause failure.
Large or small, tube leaks can compromise thermal performance, create cross-contamination, increase energy usage, and lead to serious plant capacity loss and/or shutdowns. Additionally, plant personnel can be exposed to hazardous materials and equipment can sustain serious damage.
