Pipeline Industrial Solutions


On-line, under pressure repairs are essential for maintaining the integrity and continuous flow of fluids or gases through a pipeline network. Colt utilizes techniques such as leak sealing, on-line leak repair, hot tapping, line stopping, line freezing, and composite repair solutions to address issues without the need for shutdowns or depressurization.

Each method requires careful planning, adherence to safety protocols, and consideration of specific operational parameters to ensure successful repairs. Colt’s technicians are highly experienced in pipeline repair and mitigation techniques without compromising the network. By leveraging Colt’s solutions, pipeline operators minimize downtime, reduce costs, and ensure the uninterrupted flow of fluids or gases through their infrastructure.


Clamps and enclosures are a recommended pipeline repair method in situations where the pipe cannot be taken out of service, and the leak must be repaired immediately. Standards require that clamps and enclosures used for pipeline repairs are engineered and tested to withstand the pressure, temperature, and chemical composition of the material flowing through the pipeline. The repair must also meet the design requirements and have a maximum allowable working pressure established by the industry standards.

Colt’s patented interlocking pressure seal enclosures are stocked nationwide, enabling us to rapidly repair leaking or corroded pipes when designated to be the right equipment for mitigation. Our engineering and manufacturing teams can also quickly fabricate custom clamps utilizing our stock inventory. Both stock and custom enclosures utilize perimeter seals to eliminate the risk of FME in pipeline repair.


Our experts only recommend using composite wraps on a pipe if is the leak is at 0% flow rate. Colt’s pipeline repair composite wraps are designed to address a wide range of temperatures, pressures, geometries, and chemicals, offering a safe and cost-effective solution to common integrity problems. We can utilize stop gaps, patches, or other temporary repair methods to eliminate leak to allow for a composite wrap installation. Our first step in any composite repair mitigation is to value engineer repair plans to minimize cost and maximize strength only where needed.
