Non‑Destructive Testing (NDT) for Pure Steam Generator Vessels
Our specialised non destructive testing ndt for pure steam generator vessel service delivers ultra‑reliable inspection of high‑pressure steam boiler shells, headers, and super‑heater tubes. Designed for the power‑generation sector, the solution combines ultrasonic, radiographic, and phased‑array techniques to verify wall thickness, detect corrosion‑related flaws, and confirm weld integrity without interrupting plant operation.
How It Works – Integrated Multi‑Modal Inspection
Our field engineers deploy calibrated transducers that emit high‑frequency acoustic pulses through the vessel wall. Reflected signals are captured and processed by proprietary algorithms to generate a real‑time thickness map. Simultaneously, portable X‑ray units perform radiography on critical welds, while phased‑array probes sweep complex geometries such as tube bends. The data is merged into a single 3‑D model, allowing engineers to pinpoint thinning, pitting, or cracking down to 0.2 mm resolution. All results are delivered in a certified inspection report that meets ASME Section VIII, API 570, and EN‑13445 requirements.
Application Scenarios
- New‑build commissioning: Verify as‑built dimensions and weld quality before pressure testing.
- In‑service life‑extension: Conduct scheduled 5‑year surveys to assess wall loss and plan remedial action.
- Post‑maintenance validation: Confirm that repair welds meet design specifications after overhaul.
- Regulatory compliance audits: Provide documented evidence for third‑party inspectors and insurers.

Industry Certifications & Safety
All inspection activities are performed by personnel holding ISO 9712 Level II certification and ASNT‑approved training. Equipment is calibrated annually to ISO 9001 standards, and the final inspection dossier carries a traceable audit trail that satisfies DNV‑GL, Lloyd’s Register, and local statutory bodies. Safety protocols include remote‑controlled radiation sources, confined‑space entry permits, and real‑time gas monitoring to protect both staff and plant assets.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a full‑scale vessel inspection?
We work on a project‑by‑project basis; there is no MOQ. Even a single 3‑meter diameter, 10‑meter long boiler shell can be fully inspected under the same contractual terms as larger units.
Can the testing be customised for different steel grades or alloy compositions?
Yes. Our ultrasonic settings and radiographic exposure parameters are adjusted for carbon steel, low‑alloy, and high‑temperature alloys (e.g., Cr‑Mo, Ni‑based). Custom calibration curves are supplied with the final report.
What is the typical lead time from order to on‑site inspection?
Standard lead time is 15–45 days, depending on site accessibility, required permits, and the scope of the NDT program. Expedited schedules are available for critical outages.
Do you provide a warranty on the inspection results?
Our reports are backed by a 12‑month warranty against data processing errors. Physical findings are independently verifiable by the client’s own qualified personnel.
Why Choose Our NDT Service?
- Zero‑downtime methodology: Portable equipment allows testing while the vessel remains on‑line, minimizing production loss.
- Regulatory alignment: All deliverables meet global codes (ASME, API, EN) and are accepted by major classification societies.
- Data integrity: 3‑D visualisation and cloud‑based storage ensure traceability for future life‑cycle assessments.
- Global support network: Field teams operate in Europe, Asia, the Middle East, and the Americas, providing local language assistance and rapid response.
