Infrared Thermography (IR)

IR is the only diagnostic technology that lets you instantly visualize and verify thermal performance. Nearly everything that uses or transmits power gets hot before it fails. Thermography is critical to maintaining the reliability of your mechanical systems.

Internal Rotary Inspection System (IRIS)

Internal Rotary Inspection System (IRIS) can detect corrosion, pitting and wall loss and is most commonly used for tube inspection in boilers, heat exchangers, air coolers and feed water heaters. It is particularly versatile as it is suitable for both ferrous and non-ferrous materials, and IRIS can be used on a wide range of tube diameters and wall thicknesses.

Multi-Skip Phased Array Testing

Multi-Skip Phased Array Testing is a full volumetric screening examination for the detection of both corrosion and pitting with the ability to fire multiple angles and skips, which allows for a full volumetric screening under corrosion deposits, supports, or tank annular rings.

KEY APPLICATIONS

• In-service inspection of the critical zone from the tank exterior
• Measuring corrosion under the shell to floor weld on a tank from the tank chime
• Detecting and measuring corrosion under pipe and tank supports, repads, and blisters

Corrosion Laser Scanning

Laser Scanning offers an excellent method for assessing many of the factors required for an API 653 internal or external inspection, external assessment of pipelines during ILI anomaly digs, and API 510 pressure vessel corroded area evaluation.

Using laser scanning technology, inspectors are able to complete their inspections more quickly and more accurately

Laser scanning collects millions of data points. The high-quality data provides a much greater range of reporting options, including impressive visual presentations and rich data sets for doing advanced analysis such as FEA.

Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT) utilizes multiple shear (transverse) waves fired from a single transducer housing to create an array of angles, which are projected into a color scale image, allowing for a visual representation of indications found within a specimen.

KEY APPLICATIONS

• ASME B31.1/31.3 piping construction projects
• Used in conjunction with Time of Flight Diffraction (TOFD) for ASME Sec. VIII Div. 2 pressure vessel construction projects
• API Storage Tank construction projects
• Pre-turnaround and turnaround in-service inspection

Pulsed Eddy Current (PEC)

Pulsed Eddy Current (PEC) is an advanced electromagnetic inspection technology used in detecting flaws and corrosion in ferrous materials typically hidden under layers of coating, fireproofing, or insulation.

Pulsed eddy current is one of the most versatile NDT techniques on the market. It can measure the remaining thickness of a component with a liftoff of any non-ferromagnetic form:

• Insulation with weather jacket (aluminum, stainless steel, galvanized steel)
• Concrete/Silicate
• Composite wrap/Polymer coating
• Marine growth

Remote-Field Testing (RFT)

Remote-field testing (RFT) is a non-destructive electromagnetic testing technique mainly used to find defects in steel pipes and tubes.

RFT has several benefits over other electromagnetic testing techniques:

• Suitable for ferromagnetic materials
• Equal sensitivity at the inner and outer surfaces
• Highly sensitive to wall thickness variations
• Can be used with lesser fill factors than ECT

Remotely Piloted Inspection Systems (RPIS)

Remotely Piloted Inspection Systems (RPIS), often referred to as drones or unmanned aerial vehicles (UAVs), have become increasingly popular in the field of Non-Destructive Testing (NDT). RPIS involves the use of drones equipped with specialized sensors and cameras to inspect various structures, components, and assets without causing damage. This technique offers several benefits and can be applied to a wide range of industries.

BENEFITS

• Safety: RPIS eliminates the need for human inspectors to enter potentially dangerous or inaccessible areas, reducing the risk of accidents and injuries.
• Cost-Effective: It often requires fewer resources compared to traditional inspection methods, such as scaffolding or rope access, leading to cost savings.
• Efficiency: Drones can quickly cover large areas and provide high-resolution data, reducing inspection time and improving efficiency.
• Non-Destructive: RPIS allows for non-destructive testing, meaning it does not cause damage to the inspected structures or assets.
• Access to Remote Locations: RPIS can access remote or challenging terrains, making it suitable for inspections of pipelines, power lines, and offshore platforms.
• Real-Time Data: Data is collected in real-time, enabling immediate analysis and decision-making, which can be crucial in emergency situations.
• Documentation: RPIS can generate detailed reports with visual and quantitative data, aiding in compliance and documentation requirements.

Time of Flight Diffraction (TOFD)

Often used in conjunction with phased array for code inspection of welds, time-of-flight diffraction, or TOFD, captures the full weld and heat-affected zone in a single pass of the transducers, providing the most accurate means of defect sizing. TOFD is an excellent choice for defect height and length sizing and monitoring.

TOFD is one of the most reliable non-destructive testing methods in testing welds for both pre-service and in-service inspection. An accurate assessment of welds is vital to ensure that the stability and integrity of welded structures is not compromised by defects.

This ultrasonic method is used in a diverse range of industries including petrochemical, chemical, oil and gas, power generation and fabrication.

The benefits of time of flight diffraction include:

• Can take place during production work – no shutdown is required
