Non-Destructive Testing
Non-Destructive Testing by Global Surveys helps clients inspect materials, welds, components, structures, and industrial assets without damaging the item under inspection. The service may include UT, PT, MT, VT, RT, ECT, defect detection, data review, and clear NDT reports.
As a TIC Council member and ISO/IEC 17020:2012 accredited inspection body for defined inspection activities, where applicable, Global Surveys supports safer operation, better asset reliability, and earlier detection of flaws before they lead to failure, downtime, or costly repairs.
Non-Destructive Testing for Materials, Welds and Components
Non-Destructive Testing helps asset owners, contractors, manufacturers, fabricators, oil and gas operators, construction teams, and maintenance teams reduce safety and quality risk. Therefore, the work focuses on finding defects, checking condition, and supporting decisions without cutting, breaking, or damaging the inspected item.
Ultrasonic Testing
Ultrasonic Testing uses sound waves to support the detection and measurement of flaws inside selected materials or components. As a result, UT can help assess welds, plates, pipes, pressure parts, and other industrial items.
- Internal defect detection support
- Thickness measurement where applicable
- Weld and component checks
- UT result reporting
Penetrant Testing
Penetrant Testing helps identify surface-breaking defects in suitable materials. In addition, PT is useful when the surface is accessible and the inspection scope requires a practical method for finding open cracks or similar flaws.
- Surface-breaking defect checks
- Weld and component inspection
- Visible indication review
- PT report preparation
Magnetic Particle Testing
Magnetic Particle Testing helps detect surface and near-surface defects in ferromagnetic materials. For example, MT may support inspection of welds, castings, forgings, shafts, lifting items, and other steel components.
- Surface and near-surface flaw checks
- Ferromagnetic material inspection
- Weld and casting support
- MT result reporting
Visual Testing
Visual Testing is often the first inspection step because it records visible condition. Also, VT can support review of cracks, corrosion, deformation, wear, surface damage, weld appearance, and general workmanship.
- Surface condition checks
- Visible defect observations
- Weld appearance review
- Photo evidence where applicable
Radiographic Testing
Radiographic Testing uses X-rays or gamma rays to create images of internal structure. However, RT requires strict safety controls, proper planning, qualified personnel, and clear acceptance criteria before work starts.
- Internal condition imaging support
- Weld and casting review
- Film or digital result review where applicable
- Radiography report support
Eddy Current Testing
Eddy Current Testing uses electromagnetic response to help detect defects in conductive materials. Therefore, ECT may be useful for selected surface, near-surface, tubing, or component inspection needs.
- Conductive material checks
- Surface and near-surface defect support
- Selected tubing or component review
- ECT reporting where applicable
NDT Method Selection and Typical Use
The right NDT method depends on the material, defect type, component shape, access, surface condition, safety controls, acceptance criteria, and client instructions. For that reason, the inspection scope should be agreed before field work starts.
| NDT Method | Typical Inspection Support |
|---|---|
| Ultrasonic Testing — UT | Internal flaw detection, thickness checks, weld inspection support, and selected component assessment. |
| Penetrant Testing — PT | Surface-breaking defect detection on suitable materials with accessible and properly prepared surfaces. |
| Magnetic Particle Testing — MT | Surface and near-surface defect checks in ferromagnetic materials, welds, castings, forgings, and steel parts. |
| Visual Testing — VT | Visible condition review, weld appearance checks, corrosion notes, surface damage observations, and photo records. |
| Radiographic Testing — RT | Internal structure imaging for selected welds, castings, or components, subject to safety and scope requirements. |
| Eddy Current Testing — ECT | Surface and near-surface checks for selected conductive materials, tubing, and components. |
Benefits of Non-Destructive Testing
Non-Destructive Testing supports safety, quality, reliability, and cost control. More importantly, it helps teams find issues early while keeping the inspected asset available for continued use where the result allows it.
Improved Safety
NDT helps identify flaws that may lead to failure. Therefore, teams can reduce the risk of accidents, injuries, and unsafe operation.
Lower Repair Costs
Early detection helps avoid expensive repairs and replacements. As a result, clients can plan action before defects become major problems.
Compliance Support
NDT records can support client, regulatory, site, insurance, and quality review. However, exact duties depend on the applicable rules and agreed scope.
Better Efficiency
Inspection findings can help teams understand asset condition. In addition, reports support maintenance planning and better operational decisions.
Longer Equipment Life
Regular checks can help extend equipment life by finding defects, wear, corrosion, or damage before they cause serious failure.
Clear Technical Evidence
NDT reports give decision-makers factual evidence about inspected items, methods used, findings, and limits faced during the job.
How Global Surveys Performs NDT Inspection
A clear workflow improves consistency and reduces confusion. For that reason, Global Surveys confirms the material, component, method, standard, location, acceptance criteria, and report needs before NDT work starts.
Define the NDT Scope
First, the team confirms the item, material, defect type, NDT method, access conditions, client instructions, and reporting format.
Review Available Documents
Next, inspectors may review drawings, welding records, procedures, standards, prior reports, certificates, or repair records.
Prepare the Test Area
Before testing, the work area, surface condition, safety needs, access, equipment, and method requirements are checked where applicable.
Perform the NDT Method
During testing, the selected method may include UT, PT, MT, VT, RT, ECT, or another agreed method according to the approved scope.
Record Results and Limits
At the same time, inspectors record results, indications, site notes, equipment details, photos, documents, and any limits faced during testing.
Prepare the NDT Report
Finally, the report summarizes the method used, inspected item, findings, available evidence, acceptance reference where applicable, and follow-up needs.
