Onshore CompoSol Pipeline Case Study

Middle Ease Gas Pipeline

A major Middle Eastern Gas Operator had severe corrosion problems on its National Transmission Pipeline Grid. As most of the pipeline was over 20 years old, the Operator decided on a preventative maintenance and rehabilitation programme. An Intelligent Pigging programme was launched to identify all wall defects and a rehabilitation schedule was initiated to repair and reinforce the worst of the anomalies.

Traditional techniques such as welded sleeves were costly and difficult to install and involved hot work. IMG Composites was awarded the contract to provide both a technically sound and cost effective solution with its COMPOSOL PIPELINE system. All COMPOSOL Composite repairs are designed and engineered in line with ISO 24817 and ASME PCC-2 and are carried out under Cold Work Permits.

Application is manual with light hand tools, which is important in remote areas as no heavy equipment or cranes are required. IMG Composites' composol cold work repairs are carried out online with no disruption to production by locally available, qualified applicators. The COMPOSOL PIPELINE system can be applied seamlessly for any length required at the work site.

For example, this 20inch diameter pipeline required reinforcement over a range of lengths, including 1metre, 3metre, 7metre and over 10metre sections. The concept is simple, just wrap the COMPOSOL PIPELINE system components around the pipe and allow to cure. When designed, and applied by trained applicators, in line with internationally recognised standards, it is possible to replace the strength and integrity of any pipe wall material lost due to corrosion or erosion. Repairs can be designed to have a life expectancy between 1 year and 20 years.

IMG Composites supplies an Engineered and Designed Composite Repair System for use on pipelines suffering from either internal or external corrosion, including through wall defects or mechanical damage.
