Pipeline Pigging


As industry leaders in the pipeline engineering sector, EPCM understands the importance of maintaining a constant flow of high value commodities. This is why we offer a complete range of pipeline pigging services to remove damaging debris or flow-restricting deposits, prevent corrosion cell formation, and provide data for line integrity and flow efficiency. Both cleaning pigs, which remove deposits, and intelligent in-line inspection (ILI) pigs, which are used to identify defects, are utilized throughout the pipeline lifetime. During the construction phase, pigs are used for removing construction debris, initial acceptance testing and pre-commissioning. For an operational pipeline, batching, cleaning, condensate removal, inspection, rehabilitation and regular maintenance activities benefit from the use of an effective pigging system.

Some of the pigging services EPCM offers:

  • Pig design and fabrication – body, seals, cleaning elements;
  • Pig launcher/receiver design and fabrication;
  • Product Supply – A variety of Pigs, Signallers, Tracking equipment, etc.
  • Piggability Studies and Consulting;
  • Pipeline Cleaning;
  • Pipeline Proving and Gauging;
  • In-line inspections (Caliper, Ultrasonic, MFL, Geometry);
  • Pig detection and tracking;
  • Pigging schedules and maintenance;
  • Data Analysis and Reporting.

At EPCM, with our years of pipeline industry experience, we pride ourselves on delivering safe and efficient pigging systems. By continuous research, development and investments in the newest technologies, we ensure that we stay at the forefront. From mandrel pigs, foam pigs, sphere pigs, solid cast pigs and gel pigs, to temporary or permanent launching and receiving stations, EPCM’s expert team can advise, support and deliver world-class pigging solutions.

In collaboration with our technology partners, and the use of intelligent pigs, we can perform non-destructive testing (NDT) of both the interior and exterior of a pipeline. Caliper pigs, each with an array of mechanical levers mounted on the body, are used to measure the internal geometry of a pipeline. Ultrasonic ILI’s are used for corrosion inspection and circumferential crack detection with unmatched accuracy. Magnetic Flux Leakage (MFL) tools use an applied magnetic field to detect changes in wall thickness and pipe wall cracks. Geometry pigs are designed to record dents, wrinkles, bend radius and angle etc. by making measurements of the inside surface of the pipeline. Monitoring defect growth regularly reduces the risk of costly pipeline failure which may lead to system downtime, have negative environmental impacts or endanger lives. Our smart pigging solutions enable our clients to plan and schedule pipeline maintenance effectively.
