Magnetic Particle Testing (MT) Services in Kolkata 2026 — ASNT Level III Led

Why Kolkata generates MT 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.

MT is the workhorse for surface cracking on refinery equipment — nozzle welds, skirt attachments and internally on vessels during turnaround entry, particularly where wet H2S service makes surface breaking cracks credible.

Class surveys call MT on hatch corners, crane pedestals, rudder horns and other fatigue-prone details, where the finding decides steel renewal scope.

Rolls, couplings, hooks and lifting equipment in a steel plant are examined with MT on statutory and maintenance cycles.

Turbine components, boiler headers and structural welds take MT during outages — surface cracking at stub welds and attachment details is a known header mechanism.

What typically gets examined

In practice that means MT 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 7, ASTM E709 and E1444, and the ISO 9934 series, with acceptance from the governing construction code. 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 magnetic particle 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 MT 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 magnetic particle testing services page — wet fluorescent and dry powder examination on ferromagnetic welds, castings and fatigue-critical details.
