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

Why Thailand generates RT demand

Map Ta Phut is Southeast Asia's largest petrochemical hub and sits beside Thailand's major refineries, while the Eastern Seaboard's automotive plants — the region's biggest vehicle exporter — run their own continuous inspection economy.

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.

New unit construction and revamp tie-ins in petrochemical plants specify radiography for closure welds where hydrotest is impractical, and film or digital records are retained for the unit life.

Safety-critical castings — steering knuckles, suspension components — are radiographed on sampling plans tied to process control.

High-energy piping welds in power stations are radiographed at construction and selectively in service, with records retained against creep-life assessment.

What typically gets examined

In practice that means RT work across crackers and aromatics units at Map Ta Phut, refinery process equipment, automotive production lines and castings, and gas-fired power plant — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.

Certification and acceptance in Thailand

Thai statutory requirements under DIW combine with owner specifications from PTT group companies; ASNT-based certification is standard, and turnaround seasons at Map Ta Phut concentrate demand into sharp peaks that need early crew booking.

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 Thailand

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 Thailand scope and we will respond with an honest view on mobilisation.

What Atlantis provides in Thailand is set out in full on the radiographic testing services page — film and digital radiography with the source logistics, exclusion zones and permanent image records a contract requires.
