Using a trenchless approach presents unique challenges, particularly in risk assessment and mitigation, due to the varied and often unpredictable geological conditions encountered during drilling. The integrity of the pipeline’s protective coating is crucial in mitigating these risks, as coating damage can lead to corrosion and costly failures.
The Role of Abrasion Resistant Overcoat (ARO) Coatings
Selecting the appropriate Abrasion Resistant Overcoat (ARO) coating is one of the most effective strategies to minimize the risks associated with Trenchless / HDD projects. ARO coatings act as a sacrificial layer, shielding the primary corrosion barrier from mechanical damage. Proper coating selection not only reduces the likelihood of damage but also mitigates the consequences of potential coating failure, ensuring the pipeline remains protected throughout its service life.
SFL Coatings offers the industry’s most comprehensive portfolio of ARO coatings specifically designed for Trenchless / HDD applications. Our approach to coating selection is informed by a deep understanding of the challenges faced. It is essential to consider both passive factors—such as geological composition, geographical location, and environmental conditions—and active design elements, including the pipeline’s route, diameter, and budgetary constraints.
Superior Performance Through SAIG Standards
SFL’s coatings are engineered to meet SAIG (Strain, Abrasion, Impact, Gouge) performance standards, ensuring unparalleled protection against the mechanical stresses inherent in trenchless projects. Our products deliver:
- Best Strain Resistance: Withstands significant tensile forces during pullback operations, ensuring coating integrity.
- Best Abrasion Resistance: Protects against surface wear caused by friction with soil, rock, and debris.
- Best Impact Resistance: Absorbs and distributes force from external impacts, preventing coating breaches.
- Best Gouge Resistance: Resists deep cuts and gouges that may occur due to contact with sharp geological formations.
Challenges and Solutions in Trenchless Coating Protection
Despite careful design and execution, a trenchless project inherently involves an elevated risk of coating damage. Common damage types include:
- Abrasion from soil and rock during pullback
- Impact from falling debris or handling
- Gouging by sharp rocks or unexpected geological features
- Denting, tearing, and bending due to the stresses of installation
Because these pipelines are often inaccessible for routine maintenance, the need for a robust, sacrificial overcoat becomes paramount. SFL’s ARO coatings ensure that the primary corrosion barrier remains intact, even under extreme conditions.
