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
Identify Asset Category
Process Piping Loop, Valve Body, Vessel Shell, or Tank Floor.
Pinpoint Active Damage Mechanism
CUI, Pitting, Fatigue Cracking, Erosion, or Hydrogen Induced Thinning.
Select Code-Compliant NDT Tech
Deploy PAUT, PEC, TOFD, RT, or MFL per API 570, API 598, or API 510.
