The United States currently operates 139 oil refineries, producing close to 18 million barrels of crude oil daily. However, much of the nation’s 165,000 miles of oil pipelines are over three decades old, nearing the end—or perhaps already past—their useful lifespan. As these aging infrastructures continue to deteriorate, catastrophic oil leaks, which have already wreaked havoc globally, remain an ever-present threat. The issue, as with many others, boils down to money. Pipelines are corroding faster than we can replace them, leaving behind a staggering repair bill. According to Kent Moors, a prominent oil and gas policy expert, the global demand for oil pipeline repairs stands at roughly $500 billion and is climbing by about a billion dollars weekly. So, what’s the solution? Enter HJ3’s carbon fiber.
Take, for instance, an ASTM A106 – Grade B steel vapor line header at an Alaskan oil refinery. Severe internal and external corrosion had compromised the structure, causing significant steel loss and through-holes. This deterioration left the entire system critically weak, with a complete loss of hoop strength. Repairing the 20-inch vapor line header and its attached 42-inch-diameter pipe was not only necessary but also required extreme care to avoid oxygen ingress, which could lead to combustion risks. The refinery faced a tough choice: invest heavily in replacing the pipes, which would result in substantial downtime, or opt for a more cost-effective repair solution.
After weighing their options, the refinery decided on HJ3’s CarbonSeal™ system for the repair. In just two short days, the system successfully reinforced the vapor line header and attached pipe. Given the constant exposure to chemicals, applying a chemical-resistant base and topcoat was crucial to protect the repaired area. The process began with meticulously cleaning the pipe surface to achieve a white metal finish using mechanical hand tools. Areas with through-holes and steel loss were patched up, followed by the application of a basecoat and primer on the exterior. Next, saturated carbon fiber was applied before finishing with a protective topcoat.
What made this repair truly remarkable was its efficiency—it required zero downtime, hot work permits, or welding. The hoop strength was fully restored, and the repaired header is now significantly more resistant to corrosion and chemicals. This approach saved the refinery $300,000 compared to the cost of replacement. Additionally, the repair used 22% less energy than manufacturing a new pipe would have required. It conserved nearly 33,500 gallons of water, reduced CO2 emissions by over a ton, and prevented the potential disposal of more than 1,000 pounds of steel in landfills.
