Case Study
A recent repair on a 10-inch steel pipeline in North Texas addressed corrosion and mechanical vulnerabilities at the critical soil-to-air transition zone—an area highly susceptible to coating damage and environmental exposure. StopCorr™ was applied to encapsulate the pipe, delivering self-healing corrosion protection, while BoreShield ARO® I provided an abrasion-resistant outer layer to withstand mechanical impact. This composite repair system restored piping integrity under demanding conditions, showcasing its effectiveness in mitigating external threats. Detailed inspection results, repair methodology, and environmental constraints are discussed in subsequent sections.
Soil-To-Air Transition Challenges
- The soil-to-air transition area of a pipeline is highly susceptible to corrosion due to moisture, temperature variations, and soil contaminants.
- Physical interactions with the surrounding environment can damage coatings and cause significant mechanical damage, necessitating reinforcement.
- High moisture content, oxygen levels, and bacterial activity in the soil contribute to the degradation of the pipeline’s protective coatings, making the pipeline more susceptible to corrosion.
Project Needs
- High-performance corrosion protection system capable of withstanding elevated moisture, oxygen exposure, and thermal cycling at the soil-to-air interface.
- Mechanically robust outerwrap to prevent physical damage from environmental hazards such as maintenance equipment.
- A dual-layer composite system to address both mechanical damage and corrosion threats at the soil-to-air transition.
- Long-term material stability and adhesion to maintain structural integrity under variable environmental and operational conditions.
StopCorr™ and Boreshield ARO® I Provide Maximum Protection for Soil-to-Air Transitions...
Provided Protection
A pipeline in North Texas was restored using a composite repair system that addressed external corrosion, mechanical damage, and structural integrity. StopCorr™ was applied to fully encapsulate the exposed steel, delivering long-term corrosion protection against environmental and atmospheric degradation. At the critical soil-to-air transition, BoreShield ARO® I provided superior abrasion and impact resistance to safeguard the pipeline from mechanical threats. The integrated use of StopCorr™ and BoreShield ARO® I offered a comprehensive solution to extend the pipeline’s service life at its most vulnerable transition point.
