Ultrasonic Testing (UT) & Thickness Gauging in Jubail
Ultrasonic testing sends high-frequency sound into steel and reads the echoes to locate internal flaws and measure remaining thickness. EES uses it for weld UT, plate and forging checks and thickness gauging on structures, tanks, pipework and lifting equipment, where surface methods cannot see the problem. Jubail Industrial City hosts the world's largest petrochemical complexes, requiring rigorous lifting and heavy-equipment compliance.
Ultrasonic Testing (UT) in Jubail: local context
In Jubail, proof load testing and NDT are usually planned around plant shutdowns and turnaround campaigns, when cranes lift heavy vessels, columns and prefabricated modules and every hook, wire rope and structural weld has to be trusted. Humid, salt-laden Gulf air also speeds up corrosion on booms and rigging, so EES can pair load tests with NDT of critical load-bearing parts. EES works at your location, agrees test plans beforehand and issues certificates on completion.
What we deliver in Jubail
- ✓Weld ultrasonic testing with angle-beam probes on butt and T-joints of structures, vessels and pipework, to the technique and testing level in your procedure
- ✓Straight-beam checks of plate and forgings for laminations and internal flaws, including plate behind lifting lugs and pad-eyes
- ✓Ultrasonic thickness gauging and corrosion mapping on tanks, vessels, pipework and structural members, compared with the minimum required thickness
- ✓Checks on pins, shafts and forged parts where an internal flaw or the depth of a crack is in question
- ✓Calibration on reference blocks, distance-amplitude or time-corrected gain set-up, and re-checks during and at the end of the job
- ✓Surface preparation and couplant selection suited to hot, dusty or coated surfaces, with probe and surface-temperature limits observed
- ✓Sizing and recording of indications (position, depth, length, amplitude) and comparison with the specified acceptance criteria
Standards

FAQs
Do you provide Ultrasonic Testing (UT) in Jubail?＋
Yes. EES provides Ultrasonic Testing (UT) at client sites in Jubail, including Jubail Industrial City, Jubail Commercial Port and SABIC plants. Contact us with your requirement and we will confirm scope and scheduling.
Which standards and documents apply to Ultrasonic Testing (UT) in Jubail?＋
Work in Jubail is aligned with the following standards and references: ISO 17640 (ultrasonic testing of welded joints); ASME BPVC Section V (ultrasonic examination) and ASTM E797 (manual pulse-echo thickness measurement); ISO 9712 and ASNT SNT-TC-1A (NDT personnel qualification schemes); Client UT procedure and acceptance criteria. On completion you receive: UT report stating equipment, probes, calibration blocks, technique and scan coverage; Thickness readings table with a location map or grid; Flaw record with position, depth, length and amplitude, and accept or reject result.
What is the difference between UT thickness testing and UT flaw detection?＋
Thickness gauging measures how much metal remains, to find corrosion or wear against a minimum required thickness. Flaw detection looks for discontinuities inside the material or weld, such as lack of fusion, slag or laminations, and needs a calibrated set-up and a written technique.
Can UT find weld defects that MPI or dye penetrant would miss?＋
Yes, for internal flaws that do not reach the surface, which MPI and penetrant cannot see. For fine surface-breaking cracks the surface methods are often more sensitive, so the choice depends on the defect you need to find and your procedure.
