PII_MagneScan Super High Resolution Inspection Tool
The evolution of inline inspection tools has continued at an impressive pace since their inception in the early 1970's. However the technology is not an end in itself as it needs to deliver to a very specific brief and demonstrate that pipeline systems are safe and fit for purpose.
Martin Bluck, Magnetics Product Manager at PII Pipeline Solutions (PII) explains how today’s intelligent pigs have been developed with a broad spectrum of capabilities in order to better serve customers. He goes on to discuss how technology can be leveraged to provide improved confidence to pipeline operators striving for zero pipeline failures.
In the past, different types of inline inspection tools were developed, each for a single, specific purpose. Magnetic flux leakage (MFL) pigs were developed for metal loss inspection, while caliper pigs were designed to look for dents and geometric features and mapping systems were used to investigate pipeline positioning. Within each of these three types of pig, there were multiple variants, each designed and developed to meet specific industry requirements. At one time, PII had seven different types of MFL systems in operational use, each delivering inspection results to subtly different specifications.
