Celeros Flow Technology offers a range of intrusive and non-intrusive pig detection technologies designed to help pipeline operators accurately monitor pig movement, improve operational safety, and support effective maintenance, and integrity management programmes.
Available through its GD Engineering brand, the pig signaller portfolio encompasses the intrusive Hi-T Pigalert™ alongside the non-intrusive Hi-T Magalert™ and Hi-T Ultralert™ systems, giving operators a choice of pig detection solutions suited to a wide range of installation, operational, and monitoring requirements.
Used across transmission, distribution and processing infrastructure in industries such as oil & gas and chemicals, pig signallers provide confirmation of pig launch, passage, and arrival, giving operators critical information throughout pigging operations.
Accurate pig tracking helps minimise operational uncertainty, reduce the risk of equipment damage and support maintenance activities by ensuring pigs reach their intended destinations safely and efficiently.
"Pipeline operators make significant investments in pigging programmes and inspection technologies, making accurate pig tracking an essential part of the overall operation," said Carla Connolly, global product management director at GD Engineering.
"Reliable pig detection not only helps protect those investments, but also supports safer decision-making, reduces the risk of operational disruption and provides confidence that critical maintenance and inspection activities are being carried out successfully."
The Hi-T Pigalert™ provides robust intrusive pig detection for scraper and sphere signalling applications, offering reliable visual and electrical indication of pig passage in demanding operating environments.
Available in pressure classes up to ANSI Class 2500, the design has been extensively tested with inline inspection pigs and approved for use on critical pipeline infrastructure.
The pig signaller range complements GD Engineering's broader portfolio of pipeline technologies, including Bandlock™ 2 quick opening closures, pigging systems, and pipeline intervention solutions used throughout the global energy industry.
