Frequency-Selective Method – Buried Pipeline Coating Quality Assessment Technology
This practical technology utilizes the เครื่องทดสอบความต้านทานฉนวนเคลือบท่อ to evaluate anti-corrosion coating quality on buried pipelines of any length across oil/gas transmission pipelines, urban gas networks, and oilfield systems. It supports quality inspection, integrity assessment, project acceptance, cathodic protection design, and protection effectiveness analysis.
The system measures coating insulation resistance through specialized hardware and software, providing critical data for leak detection, maintenance decisions, overhaul planning, and new construction quality validation. It processes field measurements and directly displays insulation resistance values as a definitive quality evaluation metric.
