Why Choose Us
NDT Group plays a crucial role in ensuring the safety and integrity of pipelines in the oil, gas, and other industries. These services are designed to assess the condition of pipelines without causing any damage or disruption to the pipeline itself.
We specialize in the comprehensive analysis of inspection data primarily acquired through the utilization of cutting-edge ultrasonic and advanced Non-Destructive Testing (NDT) technologies. These advanced techniques are instrumental in the detection and assessment of corrosion, cracks, and anomalies within both liquid and gas pipelines.
Our team comprises highly skilled technicians who possess an extensive understanding of specialized non-destructive testing methodologies. Among our personnel are Level 3 certified technicians who are proficient in Audit & Surveillance services and have received training as Lead Auditor ISO 9001:2008 (RABQSA). Additionally, we currently maintain a roster of technicians who hold certifications from reputable organizations, including the Canadian General Standard Board (CAN/CGSB), the American Society for Non-Destructive Testing (ASNT), the American Petroleum Institute (API), the Canadian Welding Bureau (CWB), as well as certifications from esteemed U.K. agencies such as TWI Certification Ltd (CSWIP) and Personnel Certification and Non-Destructive Testing (PCN)
Extensive Range of Inspection Services

Our
Approach
service delivery process
The process begins with an initial assessment of the pipeline’s condition and requirements. NDT Group works closely with the pipeline operator to understand their specific needs and goals.
NDT Group determines the appropriate NDT methods to be used based on factors such as pipeline material, size, and the type of defects or issues expected. Common NDT methods include:
- Ultrasonic Testing (UT): Uses sound waves to detect internal defects.
- Magnetic Particle Testing (MPT): Identifies surface and near-surface defects.
- Radiographic Testing (RT): Uses X-rays or gamma rays to inspect for internal defects.
- Eddy Current Testing (ECT): Detects surface and subsurface defects and measures wall thickness.
- Visual Inspection (VI): Involves direct visual examination of the pipeline’s surface.
NDT Group deploys trained and certified technicians equipped with specialized NDT equipment to the pipeline site. The choice of equipment and personnel depends on the selected NDT methods.
Technicians perform the NDT inspections according to established procedures. Data, including readings, images, and other relevant information, are collected during the inspection.
NDT Group’s experts analyze the collected data to identify any defects, anomalies, or structural issues in the pipeline. They determine the severity of these issues and assess the overall integrity of the pipeline.
A detailed report is generated, documenting the findings of the NDT inspection. This report includes information on the location and size of any defects, as well as recommendations for repairs or maintenance if necessary. The pipeline operator can use this information to make informed decisions about the pipeline’s integrity and safety.
Depending on the findings, NDT Group may provide guidance on necessary repairs or maintenance activities. They can also conduct follow-up inspections to monitor the effectiveness of any repairs or to assess the progression of defects over time.
NDT Group ensures that its services comply with industry standards and regulations. They may provide certification or documentation to demonstrate that the pipeline has undergone NDT and meets safety standards.
NDT Group can assist pipeline operators in setting up continuous monitoring systems, where applicable, to track the pipeline’s condition over time and detect any changes or new defects as they develop.
