Ultrasonic Testing (UT) Services in Lagos 2026 — ASNT Level III Led

Why Lagos generates UT demand

Lagos hosts the Dangote refinery and petrochemical complex — the largest single-train refinery in the world — alongside the Apapa and Tin Can port complexes, coastal terminals, and the fabrication yards at Snake Island.

In refining, UT is the backbone of the corrosion programme — thickness monitoring at condition monitoring locations across crude, vacuum and coker circuits, shear-wave and phased array on repair welds, and high-temperature techniques where insulation cannot come off.

Marine work is thickness gauging at scale — hull plating diminution against class allowables, tank internals, and shaft and rudder stock examination during docking.

Pipeline integrity leans on UT to verify in-line inspection calls — direct assessment digs confirm metal-loss depth at the anomalies MFL reported, and AUT examines new girth welds where radiography is displaced.

Fabrication shops use UT for plate lamination checks before cutting and shear-wave examination of production welds, keeping repair rates visible while the job is still on the floor.

What typically gets examined

In practice that means UT work across refinery and petrochemical units, storage terminals and jetty pipelines, fabricated structures from the island yards, and port equipment — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.

Certification and acceptance in Lagos

NMDPRA oversight and owner specifications govern; the Dangote complex applies international codes with formal vendor approval, and local-content requirements under NOGICD shape team composition on most contracts.

Examinations themselves are performed to ASME Section V Articles 4 and 5, ISO 17640 and ISO 16810, with thickness data feeding API 510, 570 and 653 remaining-life calculation. The evidence chain — technician certification current on the day, instrument and reference block calibration, and the procedure revision in force — travels with every report, because that bundle is what an audit actually checks.

Working with Atlantis in Lagos

Atlantis delivers ultrasonic testing through inspection teams mobilised to site, working under Atlantis procedures with ASNT Level III oversight — we are straightforward that this is a mobilised model rather than a walk-in local office, because for planned inspection work that is usually the better arrangement anyway: the crew, procedures and equipment arrive matched to your scope. Read the UT service overview, see how results are recorded and retrieved, or tell us about the Lagos scope and we will respond with an honest view on mobilisation.

Lagos scopes are quoted from the national ultrasonic testing service: thickness surveys, weld examination, corrosion mapping and phased array performed to a qualified procedure.
