PIGGING REDUCES PIPELINE INCIDENTS, IMPROVES LONGEVITY


In the history of pipelines, the biggest threat to pipeline safety and the major cause for most spills, injuries, and deaths within pipeline operations has always been corrosion (both external and internal). It can significantly weaken the integrity of the pipeline by thinning pipeline walls, weakening welds, and causing blockages. That was why The Pipeline Safety Reauthorization Act of 1988 was enacted: to minimize the occurrence of pipeline incidents and improve incident response, including incidents related to external and internal corrosion, and faulty welds and seams. About 20 years prior to that, pigs (instrumented internal inspection devices that pass through oil and gas pipelines) were introduced and were helping the industry to detect pipeline corrosion. But 1994 regulations were what really brought in new technology that could improve detection of potential hazards like dents and gouges, cracks in welds, and disbondment of anti-corrosion coatings. Combined with the advances in hardware and pipeline installation, pigging helps to ensure pipeline incidents are avoided so that the environment, operations and personnel are kept safe.
