Understanding Composite Repairs: Expert Insights from Brad Whelan, HJ3’s Senior Application Engineer
Composite repairs have become a go-to solution in many industrial settings. They allow for quick and effective fixes to pipelines and other critical infrastructure without the need for costly downtime. To better understand how these repairs work and their advantages, we spoke with Brad Whelan, HJ3’s Senior Composites Application Engineer, who has over a decade of experience in this field.Brad is responsible for designing composite repair systems for piping, pressure vessels, and transmission lines. His work involves collaborating with contractors globally to deliver tailored solutions that meet specific operational challenges. At HJ3, the focus isn’t just on selling materials—it's about delivering reliable, long-lasting repair solutions that keep operations running smoothly.
What types of pipe repairs do composite fiber products typically handle?
Composite repairs are commonly used for process piping, which includes elbows, tees, and pressure vessels. In the petrochemical industry, where a wide range of chemicals are handled at lower pressures and temperatures, these repairs offer flexibility and durability. For transmission pipelines, which span thousands of miles, the emphasis is on permanent, long-term solutions that can last decades with minimal maintenance.
Which defects can be addressed using composite fiber technology?
Corrosion is one of the most common issues that composite repairs tackle. This includes Corrosion Under Insulation (CUI), which often occurs when moisture builds up beneath insulation. It can also address coating failures and internal corrosion caused by aggressive chemicals like acids. Dents, often resulting from third-party damage or natural events, are another key area where composites provide an efficient fix. These repairs are designed to account for fluctuating pressures and stress cycles in the pipeline system.
What are the main benefits of using composite repairs instead of traditional methods?
One of the biggest advantages is minimized downtime. Shutting down equipment for repairs can cost millions of dollars per day, so using composites allows for faster, more efficient repairs. Additionally, composite materials are significantly lighter than steel clamps or closures—often weighing just 10% of their alternatives. This makes them easier to transport and install. Finally, composites can be deployed quickly, sometimes even on the same day, making them ideal for emergency situations.
How does HJ3’s CarbonSeal™ stand out in the market?
HJ3’s CarbonSeal™ is known for its speed, strength, and reliability. We offer same-day shipping and zero-cost inventory plans, ensuring that materials are always available when needed. Our composites are made with higher density materials, allowing for fewer layers and faster installation. Plus, our systems have been tested extensively, including full-scale testing for ASME PCC-2 compliance, proving their effectiveness across a wide range of applications.
Can you share an example of a project where composite repairs made a real difference?
A few years ago, we helped a client repair a leaking pressure vessel during a scheduled outage. The damage was near a weld seam, and there was no time for a full replacement. We worked with a nested contractor to wrap the entire head and a 4-foot section of the shell. The repair was completed in just 48 hours, allowing the facility to stay on schedule. The repair has since performed flawlessly and is expected to last until 2029.
At HJ3, we believe in providing engineered solutions that not only meet industry standards but also exceed expectations. We work closely with operators to ensure that every repair is safe, compliant, and built to last. Whether it's a small leak or a major defect, our goal is to deliver results that keep your operations running efficiently and safely.
