Industrial chimneys are subject to deterioration over time, and if left un-checked, can lead to costly repairs or even system failures. Factors such as wind loading, freeze & thaw cycles, lightning strikes, and constant contact with chemicals & smoke can damage the masonry materials and liner of industrial chimneys & stacks. Including regular inspections by qualified chimney professionals in your annual industrial chimney maintenance programs will help identify signs of trouble early, allowing problems to be corrected before they become a costly or dangerous issue.
The interior liner, the top, breeching duct inlets, and ladders and platforms are the most damage-prone areas on an industrial chimney. These locations are the hardest to see from ground level so inspections performed with rope access methods are the best way to get an accurate assessment of the condition of your stack. Our team of rope access chimney technicians offer complete inspection services that include structural & chemical attack analysis, video & photograph recordings, and detailed inspection reports outlining breaches, deterioration, and potential safety issues.
Classes of Industrial Chimney Inspections
There are 3 classes of inspections for industrial chimneys and our high access specialists can help determine which level of industrial chimney inspection is the best option for your factory, plant, or refinery.
Class I Inspection: The first level of inspection is a visual inspection that can be performed with system on-line & operating as normal. An industrial chimney tech will perform a ground level inspection of the structure using binocular, then move on to a close-up visual inspection from access ladders, platforms or other accessible vantage points. Infrared thermography is also used to check for hot spots on the industrial chimney that can indicated a damaged liner or gas leak. Class I Inspections should be performed every year to identify any potential problems that may be developing in the system.
Class II Inspection: The second class of inspection is performed with the industrial chimney off-line. Using innovative rope access techniques, our chimney technicians get a close look at both the outside and inside of the industrial chimney by scaling down the structure with proper rigging equipment. This allows the chimney technicians to get an accurate picture of the condition of the stack including any abnormalities, damage, or hazards. The liner and annulus are also thoroughly inspected and depending on the condition of the structure, non-destructive testing or core sampling may also be performed.
Class III Inspection: The most in-depth level of inspection is the Class III inspection. This class is reserved for unique circumstances that require an expansive examination for safety & stability. Any industrial chimneys that were damaged due to severe weather conditions, explosions, overheating, earthquakes or other natural disasters require a Class III inspection immediately. Also, a Class III inspection should be performed before any significant structural modifications are done such as increasing the height or adding more platforms or breechings.
Our experts also perform non-destructive testing and petrographic analysis for industrial chimneys to determine the structure integrity of the unit and provide in-depth information on characteristics of the concrete surface of any concrete industrial chimneys.
A comprehensive inspection plan is prudent for maintaining structural integrity, controlling long-term maintenance expenses, and preventing costly repairs or unplanned outages.
