API 510 & 570 Inspections

API 510 and API 570 inspections keep pressure vessels and process piping code-compliant and fit for continued service. TechCorr's API-certified inspectors pair the required visual external inspection with non-destructive examination (NDE), remaining-life analysis, and repair recommendations you can hand straight to maintenance planning or your authorized inspector.

What API 510 and API 570 cover

• API 510 pressure vessels - external and internal inspection of drums, columns, reactors, and separators, including corrosion-rate calculations, remaining life, and rerating support.
• API 570 piping systems - piping circuit definition, thickness measurement programs, injection-point and corrosion-under-insulation (CUI) inspection, and class-based inspection intervals.
• Fitness-for-service - corrosion assessment, minimum required thickness evaluation, and repair or rerating recommendations following API 579 practice.
• Documentation - inspection reports formatted for your mechanical integrity program, with defects mapped, prioritized, and tied to the next inspection date.

Methods and crews

• Ultrasonic thickness (UT) surveys with manual and automated scanning
• Phased array ultrasonic testing (PAUT) and time-of-flight diffraction (TOFD) for weld examination
• Radiographic testing (RT) and computed radiography (CR) on critical welds
• Magnetic particle (MT), dye penetrant (PT), and visual testing (VT)
• Hardness testing, positive material identification (PMI), and corrosion mapping
