Frequently Asked Questions
Which NDT methods are used in oil and gas?
Ultrasonic testing and phased array for wall thickness and weld examination; radiography for weld volumetric examination and for profile imaging of small-bore and insulated lines; magnetic particle and liquid penetrant for surface examination; eddy current and IRIS for heat exchanger tubing; guided wave for screening long insulated or buried runs; magnetic flux leakage for tank floors and in-line pipeline inspection; and visual examination throughout, which directs where the others are applied.
What codes govern NDT in oil and gas?
ASME Section V for the examination methods themselves; ASME Section VIII and B31.3 for construction acceptance; API 510 for pressure vessels, API 570 for piping and API 653 for aboveground storage tanks in service; API 1104 for pipeline girth welds; API 579 for fitness-for-service; and API 580/581 for risk-based inspection. API RP 571 defines the damage mechanisms that determine which examination is actually worth performing where.
What damage mechanisms drive inspection planning?
In refining, high-temperature sulfidation, naphthenic acid corrosion, high-temperature hydrogen attack, wet H2S cracking including HIC and SOHIC, chloride stress-corrosion cracking of austenitic stainless, corrosion under insulation, and erosion-corrosion at elbows and reducers. Upstream and midstream add CO2 and microbiologically influenced corrosion, top-of-line corrosion in wet gas, and external corrosion under coating and disbonded wrap.
How are inspection intervals set?
Under API 510, API 570 and API 653 the interval derives from measured corrosion rate and remaining life, subject to code maxima — not from a fixed calendar. That makes the quality of the thickness data decisive: readings that cannot be proven to come from the same corrosion monitoring location cannot support a defensible corrosion rate, and therefore cannot support the interval derived from it.
What qualifications should an oil and gas NDT contractor hold?
Technicians certified per method and level under ASNT SNT-TC-1A or ISO 9712 against a current written practice; inspectors holding API 510, 570 or 653 as the scope requires; ISO 17020 or ISO 17025 accreditation where third-party inspection is performed; and the operator-specific approvals that govern site access, which are separate from and additional to the certification scheme.
Can inspection data feed our integrity management system?
Yes. Results can be delivered as notifications or work orders into SAP PM, Oracle eAM, IBM Maximo or ServiceNow, or bound to locations on a 3D asset model where corrosion rates, remaining life and risk ranking update as new data arrives. The important design decision is that thickness readings attach to a persistent corrosion monitoring location rather than to a report, because that is what makes the time series usable years later.
