Eddy Current Testing (ET) Services in Kolkata 2026 — ASNT Level III Led

Why Kolkata generates ET 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 exchanger bundles are examined with eddy current at every major turnaround — bobbin screening for wall loss across thousands of non-ferrous tubes, with array or rotating probes on the indications that matter.

Marine diesel engine components, turbocharger parts and shaft tapers are examined with eddy current during overhaul, where a missed crack ends up as a tow.

Hot and cold mill product inspection uses eddy current for surface defect detection at line speed, where a missed defect becomes a claim.

Condenser and feedwater heater tubing is eddy current's core power-generation work — full-bundle screening each major outage with plugging decisions made tube by tube.

What typically gets examined

In practice that means ET 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 8 and its tubing appendices, ISO 15548, and ASTM E243 for tube examination. 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 eddy current 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 ET 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 eddy current testing services page — bobbin, array and rotating-probe tube inspection plus surface examination on non-ferrous and coated components.
