Despite conducting regular inspections and using state-of-the-art technology to mitigate potential causes of failures, longevity makes it almost inevitable that at some point a pipe will leak and need repair. Colt offers several on-line pipe repair options for straight pipe, 90° elbows, 45° elbows, tees, unions and tubing.
We strictly follow ASME (American Society of Mechanical Engineers) PCC-2 (Post Construction Committee on Repair and Rehabilitation) standards for the repair and rehabilitation of pressure equipment and piping. Our leak repair experts determine which pipe repair method to use by evaluating equipment specifications, equipment use and access to the equipment.
We take a comprehensive approach to help mitigate leaks, prevent environmental damage, and maintain the overall reliability and efficiency of the piping infrastructure. Adhering to ASME PCC-2 guidelines throughout our process ensures the piping system repair or rehabilitation meets safety standards and enables normal operation without compromising the integrity of the pipeline.
Clamps and enclosures are a recommended 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 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. Our off-the-shelf inventory:
Our experts only recommend using composite wraps on a pipe if the leak is at 0% flow rate. Colt’s pipe 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 jiffy clamps to eliminate leak to allow for a composite wrap. Our first step in any composite repair mitigation is to value engineer repair plans to minimize cost and maximize strength only where needed.
Colt utilizes pipe plugs as a temporary repair method for holes in piping. The plug is held in place with external strong backs, structurally supporting the piping component in the case of complete circumferential separation. Strongbacking is the most important component of any leak repair function when a pipe experiences:
