UT Quality/UT Quality USA servicesServices/Radiographic testing
Radiography remains the benchmark weld inspection method wherever a permanent, code-reviewable image of the weld volume is required. UT Quality USA runs the full range: conventional film RT, digital radiography (DR), computed radiography (CR) and real-time radiography (RTR), matched to the weld, the material and the schedule.
The right radiographic technique for the weld in front of the crew, in the field or the shop.
Field RT and digital radiography on new-construction and tie-in girth welds, with same-shift interpretable results on digital.
RT and DR on process piping circuits, vessel seams and nozzle welds to ASME B31.3 and Section VIII acceptance criteria.
Radiographic inspection of structural and fabricated steel welds during shop and field construction.
RT and CR on fabricated components where internal soundness has to be verified before service.
Conventional film RT where the specification calls for it or the owner prefers it.
DR and CR remove the 45 minutes or more that film development adds to every exposure, without giving up a permanent, reviewable image.
Real-time radiography for fast screening and access-limited components, with immediate feedback.
On heavy wall and on mainline AUT spreads, encoded ultrasonics can reach the answer faster. We will say which method the weld needs.
Conventional RT exposes film that is chemically developed; DR captures the image directly on a digital detector; CR uses a reusable phosphor plate scanned into a digital image. All three are interpreted against the same code acceptance criteria.
RTR produces a live radiographic image during the exposure rather than a single static shot. It is used for fast screening and on access-limited components where immediate feedback speeds the decision.
Pipeline girth welds, process piping, pressure-vessel seams and structural welds in carbon steel, stainless and other alloys, inspected to the governing code in your specification: API 1104, ASME B31 or ASME Section V/VIII.
Yes. Film RT where it is specified, DR and CR for speed, RTR for screening. One technique is not forced on every weld.
Technicians are certified Level I, II and III to our written practice under ASNT SNT-TC-1A / ANSI/ASNT CP-189, with Level III oversight of procedures and interpretation.
