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

Why Kolkata generates RT demand

Kolkata anchors eastern India's industrial corridor: IOCL's Haldia refinery and the petrochemical complex beside it downriver, Garden Reach's warship building, the Kolkata and Haldia port systems, and the Durgapur–Burnpur steel belt inland — an old industrial base whose ageing plant needs more examination, not less.

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.

Heavy fabrication attached to steelworks — ladles, furnace shells, structural rebuilds — draws radiography for coded welds.

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 refinery and petrochemical equipment at Haldia, warship and commercial hulls at Garden Reach, port infrastructure and cargo gear, blast furnaces and mills in the steel belt, and legacy thermal power plant — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.

Certification and acceptance in Kolkata

IBR governs the boiler stock, classification societies and naval rules the shipbuilding, and IOCL and SAIL their own agency approvals; personnel certification is ISNT (NCB) — whose national office sits in Kolkata — or ASNT where contracts import it.

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 Kolkata

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

What Atlantis provides in Kolkata 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.
