Boiler tube leaks in combined cycle and fossil plants are costly, hazardous, and can lead to unplanned outages and more significant damages if undetected.
Early boiler tube leak detection allows you to mitigate these risks and stay on top of your asset’s condition, enabling you to make more informed maintenance decisions. MISTRAS offers tube leak monitoring services to identify and locate tube leaks in your power plant assets, including:
Leaks in these assets can lead to extensive damage in both your equipment and facility, especially if they go undetected for long periods of time. Some of the damages that undetected tube leaks can risk include:
MISTRAS utilizes Acoustic Emission (AE) non-destructive testing (NDT) technology, which uses sound waves to listen for leaks in your equipment. By mounting non-invasive sensors on the asset, MISTRAS listens for changes in normal background noise which would indicate leaks. By using this method, operators can detect leaks before audible noises or visible dripping occurs.
Early leak detection can be crucial for plant health, allowing leaks to be detected, located, and repaired before serious damage, slowdowns in production, or costly unplanned shutdowns can occur. Monitoring solutions enable plants to maximize their asset and personnel safety, in additional to optimizing maintenance spending.
MISTRAS’ monitoring solutions keep leaks under constant watch, and locates and alerts operators to them as soon as an indication is detected. This maximizes efficiency by allowing for quick leak location, allowing plant personnel to spend less time look for the leak and more time planning for it.
Detecting and addressing leaks quickly also enables plants to avoid secondary damages such as tube separation, impingement, or destruction of adjacent tubes.
Tube leak monitoring puts decision-making in operators’ hands. You can schedule shutdowns/outages based on your operational preferences, not circumstance. This enables plant operators and upper management to wait for an optimal coverage pricing window.
Ensuring tube leaks are repaired in a scheduled, controlled atmosphere – instead of a forced, uncontrolled, and unpredictable setting – can also increase safety and decrease the likelihood of accidents during outage work.
General production is maximized because outages aren’t extended and downtime is minimized. Outage efficiency and downtime management are results of the MISTRAS’ early leak detection capabilities, which enable plants to make manageable repairs in optimal situations with the earliest possible actionable information.
Plant operators are also able to minimize visits to hard-to-access areas. Tube monitoring enables maintenance management personnel to extend intervals in between scheduled inspections, reducing the costs and hazards associated with sending technicians into high-temperature and hazardous regions of a plant.
Since tube leaks can strike at any time, MISTRAS offers hardware-as-a-service solutions to provide installation services and periodic system checkups.
Prior to installation, our system engineers walk boilers with plant personnel to aid in selecting optimal sensor locations. We also provide on-site technical support during training and system check-out for operators and electrical personnel.
After installation, MISTRAS' Surveillance teams provide daily, weekly, or monthly checks to examine data for any suspicious acoustic changes, and to troubleshoot any potential hardware issues. Our Surveillance teams are available 24 hours a day, 7 days a week for diagnostic services and maintenance consultations.
Additional, supplementary surveillance programs are also available to provide plants with additional monitoring and data analysis in between scheduled reports, including an interactive leak database for real-time leak event risk analysis.
