Industrial Integrity Asset Guide

NDT Applications & Asset Inspection Matrix

Match non-destructive testing techniques (PAUT, TOFD, PEC, RT, MFL, UT) directly to process piping, control valves, pressure vessels, storage tanks, and boiler tube bundles under API & ASME inspection codes.

3-Step Asset Selection Workflow

1

Identify Asset Category

Process Piping Loop, Valve Body, Vessel Shell, or Tank Floor.

2

Pinpoint Active Damage Mechanism

CUI, Pitting, Fatigue Cracking, Erosion, or Hydrogen Induced Thinning.

3

Select Code-Compliant NDT Tech

Deploy PAUT, PEC, TOFD, RT, or MFL per API 570, API 598, or API 510.
