Equistar Chemicals Pigs the "Unpiggable"
PASADENA, Texas--(BUSINESS WIRE)--Houston-based Equistar Chemicals, LP - Pipeline Operations, has successfully inspected, without any line modifications, a 12-mile pipeline formerly deemed “unpiggable.”Â Partnering with Quest Integrity Group, Equistar overcame design and configuration challenges which prevented conventional inspection tools from negotiating this small-diameter line. The tight radius and back-to-back bends were easily negotiated by InVista™, Quest Integrity’s ultrasonic in-line inspection technology which offers more inspection flexibility than conventional designs, among the features 1.0D bend navigability and bi-directionality.
This inspection represents a significant improvement over previous pressure testing, safely and efficiently capturing precise metal-loss and deformation dimensions with a single tool in a single pass in less than half a day. Utilizing this comprehensive and actionable pipeline data and the accompanying fitness-for-service assessment, Equistar is able to continue safe and reliable operations, maintain regulatory compliance and effectively employ best asset integrity practices in a much more cost and time effective way than before.
Equistar remains committed to forward-thinking solutions and developing and applying the latest technologies for improving pipeline integrity assessment. "Equistar's management encourages the use of this type of technology to ensure our pipelines are as safe as possible for the public, the environment and our employees," said Franklin Stagg, Equistar’s Pipeline Integrity Management Program Coordinator.
Equistar Chemicals, a subsidiary of LyondellBasell, is responsible for nearly 1,400 miles of Texas and Louisiana pipelines. Equistar transports feedstocks and refined petrochemicals used to manufacture countless everyday goods such as personal care products, fresh food packaging, lightweight plastics, construction materials, automotive components, durable textiles, medical applications, biofuels and many others.
