Radiographic Testing (RT) Services in Lagos 2026 — ASNT Level III Led

Why Lagos generates RT 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.

Refinery turnarounds pull radiography for weld acceptance on piping tie-ins and vessel repairs, where a permanent image is required before insulation and fireproofing close the work.

Shipyard new-building and major steel renewal use radiography on butt welds in primary hull structure, to class society acceptance.

Girth weld radiography under API 1104 remains the default on new pipeline construction in most jurisdictions, with acceptance criteria that differ genuinely from plant codes.

Shop radiography remains the reference for coded vessel and spool fabrication — the image travels with the data book the client audits.

What typically gets examined

In practice that means RT 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 Article 2 and ISO 17636, with acceptance from the referencing construction code and API 1104 on pipeline girth welds. 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 radiographic 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 RT 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 radiographic testing service: film and digital radiography with the source logistics, exclusion zones and permanent image records a contract requires.
