Steel pipelines are extremely capital intensive – no matter whether they are used to transport gas, water, crude oil, wastewater or any other medium. For operators of such networks it is essential to avoid any interruptions and keep stoppages to a minimum. A repair system that offers a fast and economical solution, allowing operations to continue uninterrupted while assuring top quality and safety, is needed in the market to ensure profitability.
Previously certified by DNV GL in accordance with ISO TS 24817 and now tested by TÜV Rheinland (ISO 24817, Pipeline Regulation, High Pressure Gas Pipeline Ordinance, Industrial Safety Regulation, Pressure Equipment Directive) and Lloyd’s Register (ASME PCC-2 and ISO 24817), the repair system can be used for all repair classes and all defect types, whether through wall or non-through wall. In complex test procedures spanning a period of three years, performance of the system was tested under the supervision of the certification bodies for scenarios covering various defect types, pipeline components, materials, load cases and application methods, and its use was approved for industrial, marine and offshore applications.
The Loctite Composite Repair System comprises materials for surface preparation, reinforcement, sealing, and a topcoat. The heart of the repair system is a composite material made of a glass-carbon fiber tape and epoxy resin that was purpose-developed for these applications. In steel pipelines the composite repair system reinforces damaged pipe sections and seals them while also protecting them against recurring corrosion. In addition to certified safety, the system offers real economic benefits, since it eliminates the need to replace piping components. Corroded pipes can be repaired in situ, without any interruption in operations. This bridges the time until the next planned overhaul, but can also extend the overall lifetime of the steel pipeline by up to 20 years.
