Oil and Gas
Comprehensive Ultrasonic NDT for Upstream, Midstream, and Downstream Operations
The oil and gas industry operates some of the most demanding industrial assets on earth—from downhole drilling equipment and subsea wellheads to refineries and LNG terminals—where equipment failure carries severe safety, environmental, and economic consequences. Ultrasonic testing is integral to every phase of oil and gas asset management: fabrication quality assurance, pre-service baseline inspection, in-service corrosion monitoring, and fitness-for-service evaluation. CCNDT provides a comprehensive portfolio of ultrasonic instruments, phased array systems, and thickness gauges designed for the diverse inspection needs of the oil and gas sector.
Pipeline & Flowline Integrity
Upstream gathering lines, midstream transmission pipelines, and downstream distribution networks require systematic ultrasonic inspection for corrosion, erosion, cracking, and weld defects. Inline inspection tools, field-deployable phased array systems, and ultrasonic thickness gauges form a tiered inspection strategy addressing different accessibility and accuracy requirements. Corrosion under insulation (CUI) screening using guided wave technology identifies suspect areas without costly insulation removal.
- Inline inspection data analysis for corrosion and crack feature characterization
- Phased array girth weld inspection per API 1104 and DNV standards
- Corrosion under insulation screening with guided wave technology
- Erosion monitoring at bends, tees, and choke valves
Storage Tank & Vessel Inspection
Atmospheric storage tanks, pressure vessels, separators, and heat exchangers in oil and gas facilities experience progressive degradation from corrosion, erosion, fatigue, and environmental cracking. Ultrasonic thickness surveys during turnarounds quantify wall loss and inform repair/replacement decisions. Floor plate scanning detects bottom-side corrosion and pitting that is inaccessible to visual inspection. Acoustic emission testing provides global assessment of active damage mechanisms during hydrostatic testing.
- Tank floor plate ultrasonic scanning for bottom-side corrosion mapping
- Shell course thickness survey and corrosion rate trending
- Heat exchanger tube bundle and tubesheet inspection
- Separator and scrubber weld and corrosion assessment
Downhole & Wellhead Equipment
Drilling tools, completion equipment, wellhead components, and Christmas tree valves operate under extreme pressure, temperature, and corrosive conditions. Ultrasonic inspection verifies material soundness of drill collars, heavy-weight drill pipe, and premium connections before deployment. In-service inspection of wellhead bodies, casing hangers, and tubing hangers detects fatigue cracking and corrosion erosion that could compromise well containment integrity.
- Drill collar and heavy-weight drill pipe body and connection inspection
- Premium thread connection seal surface and root crack detection
- Wellhead body and casing hanger fatigue crack assessment
- Christmas tree valve body and bonnet weld examination
