Fossil Fuel/Coal

Solutions to Maximize the Life of Fossil Fuel Assets

Safe, reliable fossil-powered plants remain a critical part of the energy equation in North America. With decades of experience, IIA can help plant personnel navigate the challenges of this rapidly changing industry and maximize the life of assets.

As a full-service inspection company, IIA offers conventional and advanced non-destructive examination (NDE) to pinpoint and analyze cracks, corrosion, erosion and other service-related damage in power and recovery boilers, piping systems, turbine decks — every corner of your plant. And our services don’t stop there. Our team is also experienced with lift and other mechanical devices that support your operations.

Whether you need help with routine examinations, overall condition assessments, compliance issues or an unexpected equipment challenge, IIA can deliver the answers you need to make critical decisions — fast.

IIA combines boiler visual inspections with ultrasonic thickness surveys to perform overall condition assessments to identify repair work during maintenance outages. This combination of inspections being performed during outages increases the likelihood of reducing forced outages and effectively running more consistently between planned maintenance outages. Existing customers see the difference between general boiler inspections performed by competitors and our established practice of surveying erosion/corrosion combined with visual inspections to locate damage that could potentially bring a unit off-line for unexpected forced outages.

Inspection Methodologies

Visual Inspection

For DA tanks, steam turbines, fans, pressure vessels, high energy piping, stack/tower, etc. Our highly skilled employees will inspect for indications such as cracks, corrosion, erosion, damage, and structural integrity.

Ultrasonic Thickness Surveys & Flaw Detection

A volumetric non-destructive testing method that uses sound waves to propagate through an object.

Magnetic Particle Testing

A non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part to facilitate flaw detection.

Dye Penetrant Testing

A widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). PT is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

Certified Welding Inspections

Qualification to either American Welding Society (AWS) or American Society of Mechanical Engineers (ASME) standards through Certified Welding Inspectors (CWI) with mobile capabilities for your convenience.

Phased Array Ultrasonic Testing

An advanced method of ultrasonic testing used to determine component quality and detect flaws in manufactured materials such as welds. In addition, it can be effectively used for wall thickness measurements in conjunction with corrosion testing. This NDT technique is minimally invasive, highly flexible, and offers multiple applications.

Eddy Current Examinations

An electromagnetic testing method used in NDT to detect near surface anomalies in conductive material.

Metallurgical Replications

An NDT method that duplicates the microstructure of a component in order to observe grain structure at high magnification.
