Increased Use of Remote Field Technology for In-Line Inspection of Pipelines

The paper discusses the growing importance of Remote Field Technology (RFT) in the in-line inspection of pipelines, particularly in scenarios where traditional magnetic flux leakage (MFL) tools face challenges. Over the past decade, RFT has emerged as a valuable alternative, especially in situations involving internal scale, deposits, liners and complex pipeline geometries.

RFT operates on the principles of electromagnetic induction, which were first discovered and documented by pioneers like Michael Faraday and Heinrich Lenz in the 19th century. Unlike MFL, which relies on permanent magnets, RFT generates alternating current to produce a magnetic field, allowing it to measure parameters such as relative permeability and wall thickness without attempting magnetic saturation.

One of the key advantages of RFT is its ability to inspect through scale, coatings, and liners with equal sensitivity to outer diameter (OD) and inner diameter (ID) wall loss. This capability makes it suitable for various pipeline materials and conditions, including those with internal tubercles, sludge, sand, wax, and oil deposits. RFT tools can operate in tethered or free-swimming modes, offering flexibility in inspection distances and pipeline sizes.

The paper called “Increased Use of Remote Field Technology for In-Line Inspection of Pipelines Proves the Value of the Technology for this Application” presents several case studies illustrating the effectiveness of RFT in detecting corrosion, scale, and other defects in pipelines of different materials and sizes. Additionally, it highlights RFT’s capability to measure stress in pipelines, which is crucial for preventing leaks and failures caused by fatigue and stress corrosion cracking.

Overall, the paper concludes that RFT has become a well-established technique for pipeline inspection, offering significant advantages over traditional methods like MFL. Its versatility, ruggedness, and ability to provide accurate measurements through various pipeline conditions make it a valuable tool for ensuring the integrity and safety of critical pipeline assets.
