Oil & Gas NDT & Asset Integrity Services
Inspection for every stage of oil and gas, from wellsite and pipeline to tank farm and refinery, with crews based in the basins you operate in.
TechCorr has inspected oil and gas assets since 1999, when the company started in Maracaibo, Venezuela. Today more than 400 professionals across 14 US offices cover upstream, midstream and downstream work, with local crews in the Permian, Delaware, Eagle Ford, Bakken and Powder River basins and along the Gulf Coast refining corridor.
Upstream
Wellsite, battery and gathering-system NDT: phased array UT, shear wave UT, UT thickness, corrosion mapping and PMI. Basin-based crews work from Odessa, Carlsbad, Three Rivers, Williston and Gillette, with no mob/demob charges inside our Permian-Delaware service area.
Midstream
Pipeline integrity digs and in-line inspection validation, AUT girth weld inspection and X-ray crawlers for new construction, guided wave screening of long pipe runs, and API 653 inspection for terminals and tank farms.
Downstream
API 510 pressure vessel and API 570 piping inspection, heat exchanger tube inspection (IRIS, RFT, NFT), high-temperature hydrogen attack assessment, HF alkylation unit programs, sphere and drum internals, and turnaround support. Rope access teams reach flare tips, columns and insulated lines without scaffolding.

Real-world case studies where TechCorr applied these capabilities to oil & gas assets — linking field outcomes back to the services above.
Safeguarding Asset Integrity through Advanced NDT: Naphtha Piping System Assessment
A comprehensive inspection of a fire-exposed Class 2 carbon steel NAFTA piping system revealed a 22% wall loss relative to nominal thickness, with metallographic and hardness testing confirming preserved material integrity.

Ensuring Asset Integrity Post-Fire: Horizontal Drum Vessel Inspection
Following a fire incident, TechCorr performed a comprehensive external API 510 compliance inspection of a 60-inch-diameter horizontal drum, using ultrasonic thickness measurements at selected Condition Monitoring Locations to confirm a low 0.5 MPY corrosion rate and preserved metallurgical integrity, and to guide targeted recoating and maintenance recommendations.

Forensic Failure Analysis: Unraveling the Causes of a Refinery Fire Incident
A detailed forensic investigation determined the fire was caused by a fatigue crack in a half-inch union nipple to bushing connection, with finite element analysis and metallographic testing confirming vibration-induced fatigue as the root cause.

Compare UT and RT for weld inspection, including accuracy, speed, safety, costs, ROI examples, and TechCorr’s hybrid approach.
Five warning signs—pressure drops, vibration, leaks, discoloration, and outdated records—can signal equipment failure. Proactive NDT helps identify risks before they escalate.
TechCorr’s 3-Tier Proactive NDT System uses baseline scans, predictive analytics, and planned repairs to reduce downtime and inspection costs.
