Corrosion Mapping & Advanced NDT

Introduction

Corrosion Mapping & Advanced NDT techniques are essential for assessing wall loss, pitting, erosion, and degradation in critical assets such as pipelines, pressure vessels, storage tanks, heat exchangers, offshore structures, and process equipment. These methods provide high‑resolution data that supports fitness‑for‑service (FFS) evaluations, remaining life assessments, and asset integrity management.

Advanced NDT technologies such as Automated Ultrasonic Testing (AUT), Phased Array Corrosion Mapping, Time‑of‑Flight Diffraction (TOFD), Long‑Range UT (LRUT), Guided Wave Testing, and Digital Radiography enable inspectors to detect corrosion under insulation (CUI), internal wall loss, and hidden defects with exceptional accuracy.

This GTMCS Corrosion Mapping & Advanced NDT program provides deep technical training in corrosion mechanisms, advanced scanning techniques, data interpretation, and compliance with API 570, API 510, API 653, ASME, ISO, and RBI frameworks.
