IAFD is requested to visit plants to review expansion joints that may be failing or damaged, this is common each day of the week. While on the visits we noticed a trend; we found more joints or seals damaged then the plants had originally identified. With the sheer volume of seals on a combined cycle machine, this doesn’t come as a huge surprise; however, it still poses the concern; how many unknown issues are there on the machine? Fast forward to the next outage, if any of these seals or joints were still unidentified they became reactive maintenance items and unaccounted for in the budget. This is a costly and concerning item for plants trying to work inside a budget and possibly a short outage. IAFD saw the need and developed a solution, the Expansion Joint Directory. The EJD is a machine wide index of all fabric expansion joints starting with the air inlet through the stack outlet. We visit your site while the machine is online and hot, survey all the fabric joints with a thermal imaging camera, then process the data section by section showing the condition of all joints on your machine. The books are organized to show the current conditions, our experienced engineer’s notes on the approximate lifespan they have left, and all the photos taken on the survey. Furthermore, we provide you with a scheduled priority list of all the concerns and how fast they should be addressed. The purpose of this directory is to provide you with the view of every seal on your machine in under 2 seconds without having to leave your office. At that point, you can choose the specific area you want to target, dig into the data page, photos and IR photos to see whats taking place.
Please contact us today, we can have an engineer on site to survey and provide you the view of your whole machine in an instant. We have been very successful in reactive maintenance moments but proactive maintenance is our target and agenda.
