What are the most popular pipe inspection techniques?

The best and most popular pipe inspection techniques include pipeline radiography (RT) and ultrasonic testing (UT), including phased array ultrasonic testing (PAUT). 

 

These popular pipe inspection techniques are forms of NDT pipeline inspection and can be used to detect flaws without harming the asset. For example, advanced UT inspection methods, such as the total focus method (TFM), can accurately and cost-effectively detect manufacturing flaws, in-services flaws and parent metal flaws in pipelines. The M2M GEKKO, used by the NDT pipeline inspectors at Buffalo, is one of the most advanced tools available for pipeline inspections. It combes UT methods with advanced TFM, allowing for reliable, in-depth inspections. 

 

What is UT in piping?

 

UT in piping is a non-destructive testing (NDT) method. UT, or ultrasonic testing, allows NDT technicians to evaluate pipelines for potential flaws. This can be done during the construction of a pipeline or even while it is in use. 

 

UT is one of the best methods of non-destructive testing. Ultrasonic testing works by using high-frequency sound waves to measure various material properties. UT is especially helpful in pipeline inspection because it allows technicians to determine the location, length and type of flaw that is detected. This makes UT one of the most reliable and cost-effective NDT pipeline inspection methods available today.

 

What is pipeline integrity?

 

Pipeline integrity refers to the condition of a pipeline. Pipeline integrity management is an important aspect of pipeline management and ensures that a pipeline, and its components, are in proper working condition. 

 

Non-destructive testing (NDT) is used to ensure pipeline integrity. NDT offers reliable methods of flaw and corrosion detection. This not only safeguards the reliability, efficiency and longevity of the pipeline but also the well-being of the public and the environment. By using NDT to monitor pipeline integrity, proactive measures can be taken to mitigate any risk and ensure the safety of the pipeline. Pipeline integrity management, with the help of NDT, is an ongoing process.

 

What do pipeline inspectors do?

 

NDT pipeline inspectors use non-destructive testing methods and technology to assess pipelines for flaws, damage and corrosion. A qualified pipeline inspector will examine a pipeline using advanced NDT technology, like the M2M GEKKO, and provide a report of their findings and opinions. The higher the certification level a pipeline inspector has, the more their opinion is valued and trusted. As well, inspectors with higher certifications can perform more complex pipeline inspections. 

 

Regardless of their certification level, all pipeline inspections should have a deep understanding of NDT technology, pipeline materials and corrosion. This knowledge will help them to accurately examine and evaluate pipelines for flaws and damage.

 

What is the best pipeline corrosion inspection technique?

 

Advanced total focus method ultrasonic testing (or TFM UT) is the best pipeline corrosion inspection technique. TFM UT can be used to detect corrosion on in-service pipelines. This method is fast, accurate and cost-effective. In conjunction with visual inspection and evaluation provided by API 510, 570 or 653 inspectors, TFM UT offers the most reliable option for pipeline inspection. 

 

Currently, Buffalo Inspection Services is the only company using advanced TFM UT for in-service inspection. The advanced TFM UT used by Buffalo NDT technicians can detect corrosion on flange faces and hydrogen-induced cracking. This advanced technology prevents unexpected losses, as well as costly downtime.
