Magnetic Flux Leakage (MFL) and Ultrasonic Testing (UT) Pigging

Pigging services are widely used in the oil and gas industry to maintain the integrity and efficiency of pipelines. Pigging refers to the practice of inserting a specialized tool, called a pig, into the pipeline and pushing it through using the flow of the product. The pig is designed to scrape and clean the interior of the pipe, removing buildup and debris and detecting any defects or damages that may affect the pipeline’s performance.

Magnetic Flux Leakage (MFL) pigging is a type of pigging that uses magnetic fields to detect any corrosion or metal loss in the pipeline. MFL pigs are equipped with magnets that create a magnetic field around the pipeline, and any anomalies in the magnetic field can indicate the presence of corrosion or metal loss. This allows operators to identify areas of the pipeline that may require repair or replacement before they become a safety hazard.

Ultrasonic Testing (UT) pigging is another type of pigging that uses high-frequency sound waves to detect defects in the pipeline. UT pigs emit sound waves that travel through the pipeline and bounce back when they encounter a defect, such as a crack or a dent. This allows operators to identify areas of the pipeline that may be weakened and require repair or reinforcement.

In addition to MFL and UT pigging, there are other types of pigging services that may be used in the oil and gas industry, including cleaning pigs, smart pigs, and gauge pigs. Cleaning pigs are used to remove debris and buildup from the pipeline, while smart pigs are equipped with sensors and data collection devices that can provide detailed information about the condition of the pipeline.
