Tailings Pipeline In-Line Inspection Services
Reliable, High-Resolution Inspection for Tailings & Slurry Pipelines
Tailings operators face some of the industry's most challenging integrity threats. Abrasive slurry, accelerated wear, and difficult operating environments rapidly wear away at assets. Operators typically use estimated wear rates and spot checks to monitor their assets, but this risks premature replacement of sections.
In-line inspection allows operators to more precisely manage their assets—boosting efficiency while reducing replacement costs.
For over 45 years, Dexon has helped operators obtain the integrity data needed to support safer, more informed asset decisions.
