What Radiographic Testing (RT) actually detects

Radiography passes X-ray or gamma radiation through the component onto film or a digital detector, producing a permanent volumetric record. It remains the reference method where a reviewable image of the through-wall condition is required.

Porosity, slag inclusions and volumetric weld defects
Incomplete penetration and lack of fusion
Cracks favourably oriented to the beam
Wall loss and internal deposits under insulation via profile radiography
Corrosion in small-bore piping without insulation removal

Codes and acceptance criteria applied

Examinations are performed to written procedures qualified against ASME Section V Article 2, ASME Section VIII Division 1 UW-51/UW-52, AWS D1.1 Section 6, API 1104 and ISO 17636. Acceptance criteria are taken from the construction or in-service code governing the item — ASME Section VIII for pressure vessels, ASME B31.3 for process piping, API 510, API 570 and API 653 for in-service equipment, and AWS D1.1 for structural steel.

How the examination is controlled in Portland

Every examination carries its own evidence chain: the technician's certification for the method and level under ASNT SNT-TC-1A or ISO 9712, current on the day of the inspection; the calibration status of the instrument, probes and reference blocks used, traceable under ISO 17025; and the revision of the procedure and technique sheet in force at the time. That bundle is what a client audit examines, and it is recorded automatically rather than assembled afterwards.

Reporting and follow-up

Results are issued in the client's required format with indications located against the component and, where relevant, against a corrosion monitoring location so thickness trends stay continuous between campaigns. Findings can be delivered into the client's own maintenance system, or onto a 3D asset model where remaining life and risk-based inspection ranking update as new data arrives.
