Crack Detection and Sizing
Crack detection and sizing are critical aspects of non-destructive testing (NDT), which involves inspecting materials and components for defects without causing damage. We use several techniques for crack detection and sizing, including ultrasonic testing, radiography, magnetic particle inspection, and eddy current testing. The specific technique used depends on the material being inspected, the size and type of the crack, and the required level of accuracy and sensitivity. According to the needs Boilerdom use modern ultrasonic techniques such as phase array and TOFD or conventional techniques for crack detection and sizing. Crack detection and sizing require a thorough understanding of the inspection requirements, selection of appropriate equipment and techniques, and the ability to interpret and analyze the inspection results accurately. Effective crack detection and sizing are crucial for ensuring the reliability and safety of materials and components in industry.

Conventional END Methods and Techniques
conventional NDT methods and techniques are effective for detecting a wide range of defects and anomalies in materials and structures. These methods can provide accurate and reliable results when performed by experienced and qualified Boilerdom’s technicians. However, they do have limitations in terms of their ability to detect certain types of defects or anomalies, and that is why more advanced or specialized techniques may be required in some cases.

Creep Damage
Creep damage is a type of material degradation that occurs under prolonged exposure to high levels of stress at elevated temperatures. Creep is a slow and time-dependent deformation that occurs in a material under constant load or stress. This deformation can cause microstructural changes, including the growth of voids and then cracks which can ultimately lead to the failure of the material. Creep damage is commonly observed in materials such as metals, ceramics, and polymers used in high-temperature applications, such as in boilers components. The damage is often characterized by cracks, voids, or other types of defects that result from the accumulation of creep strain over time. In some cases, creep damage can lead to catastrophic failure, especially when it is not detected and repaired early. Proper monitoring and inspection techniques, such as non-destructive testing and periodic maintenance, can be done by Boilerdom to detect and repair any damage before it becomes a safety hazard.

Material Qualiry Verification
materials quality verification is a critical aspect of ensuring the safety, reliability, and durability of products and structures made from various materials. It requires a thorough understanding of the material requirements, selection of appropriate materials, testing and inspection, documentation and traceability, and supplier evaluation and control.

Phased Array and TOFD. Image Ananlysis and Evaluation.
Phased array and time-of-flight diffraction (TOFD) are advanced non-destructive testing (NDT) techniques used to inspect materials and structures for defects. Image analysis and evaluation are crucial steps in the inspection process, as they involve interpreting the inspection results to identify and characterize any defects or anomalies present. Phased array and TOFD techniques use ultrasonic waves to inspect materials and structures. Phased array involves the use of multiple ultrasonic probes that can be controlled electronically to adjust the beam angle and focus. This allows for faster and more accurate inspections of complex geometries, such as welds or curved surfaces. TOFD involves the use of two probes to detect the time difference between the ultrasonic waves emitted and received, which can be used to accurately measure the size and location of any defects.

UT Procedure Development and Qualifications
Ultrasonic testing is used to detect flaws, defects, and changes in material properties in various industrial applications, in particular boiler examination. Boilerdom will help you in developing and qualifying an ultrasonic procedure which according to your requirements could involve one or all of these steps: -Defining the inspection requirements: This step involves understanding the inspection needs and defining the acceptance criteria, such as the size, location, and type of defects to be detected.
-Selecting the equipment: This step involves selecting the appropriate ultrasonic equipment, including the transducer, couplant, and the instrumentation required for signal processing and analysis.
- Developing the ultrasonic procedure: This step involves developing the ultrasonic procedure that outlines the inspection parameters, including the frequency, amplitude, and mode of inspection. The procedure should also specify the test setup, scanning technique, and interpretation criteria. - Conducting a feasibility study: This step involves conducting a feasibility study to ensure that the selected ultrasonic procedure is capable of detecting the required flaws and defects.
-Qualifying the ultrasonic procedure: This step involves qualifying the ultrasonic procedure by demonstrating its effectiveness and reliability through a series of tests, including reference standards, calibration blocks, and test pieces. The qualification process should also include assessing the inspector's competence to perform the inspection. - Implementing the ultrasonic procedure: This step involves implementing the ultrasonic procedure in the field and ensuring that it is followed consistently. - Monitoring and reviewing the ultrasonic procedure: This step involves regularly monitoring and reviewing the ultrasonic procedure to ensure that it remains effective and relevant over time. Overall, developing and qualifying an ultrasonic procedure is a crucial step in ensuring the quality and reliability of ultrasonic testing results. It requires a thorough understanding of the inspection requirements, selection of appropriate equipment, development of the procedure, qualification testing, implementation, and ongoing monitoring and review.
