What is Magnetic Flux Leakage (MFL)?

Magnetic Flux Leakage (MFL) is a widely trusted inline inspection (ILI) technology, introduced in the 1980s. Over time, it has evolved into a highly accurate method for assessing pipeline integrity.

Advanced Technology

Our MFL tools feature high-resolution sensor arrays. Direct Magnetic Response (DMR) sensors help differentiate internal from external features. 3P Services has been offering MFL inspections since 1994. We provide tools from 2” to 48” for multi-diameter pipelines, tight bends, high-speed, high-pressure, and high-temperature conditions. All tools can operate bi-directionally.
