UT Quality/UT Quality USA industriesIndustries/Mining & minerals
On a mining site the two questions are usually the same two: is the new weld sound, and how much wall is left in the line that is already running. UT Quality USA answers both — weld inspection by radiography, ultrasonics and the conventional methods, and thickness and corrosion mapping recorded as data your engineers can act on.
The scope UT Quality USA crews are asked for on this work.
Girth, branch and fabrication welds on slurry, process, water and utility piping, inspected by radiography or encoded ultrasonics to ASME B31.3 or the code the specification names.
Ultrasonic thickness surveys, phased array corrosion mapping, remaining wall thickness and pit depth, with C-scan maps and 3D laser mapping where the geometry has to be recorded as well as the wall.
Conveyor and plant structural steel, pipe racks, platforms, equipment supports and their connections, inspected by MT, PT, UT and VT against AWS D1.1 acceptance criteria.
Welded tanks, pressure vessels and nozzle welds, and the spools, skids and structures fabricated for the plant, with positive material identification where alloy or wear-resistant material has to be confirmed.
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: ASME B31.3 for process and slurry piping, AWS D1.1 for structural welds, ASME Section VIII for pressure equipment, API 650 for welded storage tanks, ASME Section V for examination and ASME Section IX for procedure and welder qualification. Where the site works to a different standard, the work is inspected and reported to that one.
Plant work is bought in shutdown windows, so the useful measure is how much scope a crew covers before the plant restarts and how clean the records are afterwards. The same crews carry ultrasonic, radiographic and conventional capability, so a thickness survey, a weld scope and an alloy check do not need three mobilizations.
Yes. Ultrasonic thickness readings and phased array corrosion mapping give remaining wall thickness and pit depth, recorded as C-scan maps and readings rather than a verbal call.
Crews are sized to the window and staffed through the union hall, and encoded ultrasonics returns a result immediately and without the exclusion zone a radiographic shot imposes on a working area.
Yes. Plant structural steel, racks, platforms and supports are inspected by MT, PT, UT and VT against AWS D1.1, alongside the piping scope on the same mobilization.
UT Quality USA performs and documents the nondestructive examination. Rope access, hoist, shaft, headframe, wire-rope and lifting-gear inspection, geotechnical and tailings work and MSHA certification of any kind are outside this scope, and the remaining-life or fitness-for-service determination stays with the owner or their engineer.
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.
