The stack expansion joint, sometimes called the HRSG outlet, is the very large joint adjacent to the stack. These joints typically last (10-12) years depending on the environment and location of your plant. IAFD manufactures and installs these stack joints in both the flat and U-shape configurations, depending what style you have.
Sometimes the joints fail circumferential, but in many cases only the bottom or top sections will due to corrosion.
We can replace just the damaged areas, which results in huge reduction in cost related to scaffolding, labor, and the length of the belt. We will remove the section, install all new hardware, and replace with a spliceable material.
