UT Quality/UT Quality USA industriesIndustries/Hydrogen & carbon capture
Hydrogen and CO2 projects are being built with the same welding processes and the same inspection methods as the rest of the pipeline and plant estate — under codes written for the service. UT Quality USA inspects that welding with automated ultrasonics, radiography and the conventional methods, to the code the specification names.
The scope UT Quality USA crews are asked for on this work.
Mainline and tie-in welds on carbon dioxide pipelines, inspected by automated ultrasonic testing or radiography to API 1104, with ASME B31.4 governing the system.
Welds on hydrogen piping and pipelines where ASME B31.12 is the governing code, inspected by the method the specification names.
Station, compression and injection facility piping, vessels and supports, inspected to ASME B31.3 and Section VIII.
Interconnecting and utility piping between capture, compression and transport, inspected by radiography or encoded ultrasonics.
Automated ultrasonic testing, phased array and TOFD, semi-automated ultrasonics, radiography by film, computed, digital and real-time methods, and the four conventional methods — magnetic particle, liquid penetrant, ultrasonic and visual testing — plus positive material identification. UT Quality’s automated ultrasonic system is proprietary, designed and built in-house.
Inspected and reported to the code your specification names: API 1104 for pipeline girth welds, ASME B31.4 for carbon dioxide pipelines, ASME B31.12 for hydrogen piping and pipelines, ASME B31.3 for facility process piping and ASME Section VIII for pressure equipment.
These are new-build programs with owner scrutiny on every weld, which is exactly what encoded inspection data is for: flaw height and length measured to a known accuracy, with every A-scan retained and reviewable long after the crew has left.
Carbon dioxide pipelines are normally designed to ASME B31.4, with girth welds inspected to API 1104. The specification decides, and inspection follows it.
ASME B31.12 is the ASME code written for hydrogen piping and pipelines. Where a specification names it, inspection is performed and reported to that code.
Where the specification allows a volumetric method other than radiography, encoded AUT gives measured flaw height with the data retained, which is what alternative acceptance criteria depend on.
Yes. Compression, injection and interconnect piping and pressure equipment are within scope alongside the pipeline.
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. UT Quality USA is a union operation.
