Soil to Air Pipe Coating

 Soil-to-Air Transitions: One of the Most Vulnerable Spots on Any Pipeline

Soil-to-air transitions (SATs) are notorious for being one of the most challenging areas to protect on a pipeline—and for good reason. This short section of pipe is exposed to a perfect storm of corrosion risks that rarely exist all in one place elsewhere on the line.

At a soil-to-air transition, coatings must withstand:

• Standing water and trapped moisture

• Soil stress and backfill loads

• Differential pipe movement

• UV exposure once above grade

• Wide and repeated temperature swings

Individually, any one of these factors can compromise a coating system. Combined, they create an environment where traditional coatings often struggle to perform long-term.

That’s where a properly designed system makes the difference.

Using Stopaq Wrappingband in conjunction with the appropriate Outerwrap and an Outerglass Shield delivers genuine, best-in-class protection for this highly vulnerable section of pipeline. The visco-elastic nature of Stopaq provides permanent adhesion and sealing, while the outer layers supply the mechanical protection, UV resistance, and durability required for above-grade exposure.

Even better, this system isn’t limited by operating temperature. Variants of the Stopaq SAT system can be applied on pipelines operating anywhere from -45°C (-49°F) up to 95°C (203°F)—making it suitable for a wide range of climates and service conditions.
