API 570: Pipeline Inspection Code | NDT Standards

Pipeline Inspection Code

Standard for in-service inspection, maintenance, repair, and rerating of oil and gas pipelines. API 570 mandates periodic external ultrasonic thickness inspections, pigging (internal inspection), radiography of repairs, and visual inspections. Compliance with API 570 is legally required for pipeline safety. API 570 inspector certification is recognized globally.
