Corrosion Monitoring Services Inspection Services

The goal of every CMS inspection is to analyze the current condition of the air heater, identify the root cause of damage, and provide our clients with long term solutions.

CMS offers a wide range of inspection options that can identify any existing tube failure and accurately predict future failure rates. The thoroughness of a CMS inspection helps ensure that the condition of the air heater never compromises operational or pollution control objectives and we can make maintaining a zero leakage air heater an economic reality.

After we complete any inspection, all of our findings and recommendations are detailed in our executive summary report. Depending on the type of inspection performed, the executive summary may include corrosion rate charts, ultra-sonic readings, failure rate metrics, detailed tubesheet maps, and maintenance recommendations.

Our highly trained and skilled inspectors significantly enhance quality control and help prevent costly outages on equipment by evaluating wear and internal degradation. CMS can also help customize the ideal inspection based on your objectives and needs.

What Inspection is Best for Your Plant?

Selecting the right type of inspection is an important first step in the maintenance process. For new units that aren’t currently using excess fan energy, or experiencing problems with downstream pollution control equipment, CMS generally recommends a visual inspection.

For older units, or where operators have seen increased fan energy consumption, unusual O2 levels, or problems with downstream pollution control equipment, CMS generally recommends one of our more comprehensive inspections using state of the art non-destructive testing.

Operational Analysis

On a post or pre-inspection basis, CMS also offers an operational analysis that brings to light the negative financial impact to plant operation caused by the condition of the air heater. During this analysis, CMS prepares a detailed report that correlates the changes in fuel consumption, parasitic losses, and pollution control equipment performance to the condition of the air heater. This engineering analysis is based off of current plant operational data and our reports have been shown to be extremely accurate through third party audits.

CMS Reports

Financial Reports

CMS provides Tubular Air Heater Leakage Financial Impact Reports to help our clients exceed their operational goals.

Executive Summary

Our comprehensive inspection report includes gas flow drawings, ultrasonic testing charts, tube sheet maps, and repair recommendations.

Failure Rates and Metrics

CMS uses several different non-destructive testing methods in order to provide the most detailed information for our clients.

Photos and Videos

CMS provides our clients with extensive photos and videos during inspections.

CMS offers a wide variety of non-destructive testing (NDT) inspections using industry-leading technologies. NDT is a great method to identify current tube failures and to chart both corrosion and erosion failure rates. This information is a great resource in the planning stage, and for determining a proper scope of work.
Additionally, NDT is sometimes the only reliable method to identify when or where a failure has occurred. This is particularly true for air pre-heaters that feature long tubes or where access for a visual inspection is limited.
When recommending a NDT inspection, CMS takes into account the unit’s history, fuel source, and design. We most commonly recommend the following non-destructive testing methods:


Visual Inspections

The damage mechanisms of dew point corrosion, external corrosion, fly ash erosion and mechanical erosion are identified and mapped in detail.

Acoustic Eye Testing

The Acoustic Eye sends a sound wave down a tube and back, showing flaws in the tube, in real-time.

Eddy Current Testing

Measures the wall thickness of tube by utilizing electromagnetic induction to detect discontinuities in conductive materials.

IRIS Testing

An internal rotary inspection system or IRIS is primarily used to detect extremely accurate wall thickness measurements.

Pressure Testing

CMS measures and quantifies the air leakage in tubular air heaters by pressurizing tubes and measuring pressure.

UAV Inspection

CMS utilizes a fully integrated UAV guided inspection system that rapidly gathers and analyzes thousands of data points using cutting edge sensory equipment and high resolution cameras.

Rope Access Inspections

Our NFPA certified inspectors can provide a thorough inspection of any area that requires high angle or rope access.
