Mainline Pipeline Inspection

Mainline pipeline inspection covers the girth welds and long runs of transmission pipeline where NDT quality, production rate, and documentation decide whether the spread stays on schedule. TechCorr fields automated ultrasonic testing (AUT) crews, X-ray crawlers, and scanner crews built for mainline work, with quality systems written to the pipeline operator's specification.

Mainline pipeline services

• AUT girth weld inspection - phased array and TOFD girth weld examination with flaw sizing for engineering critical assessment (ECA).
• Radiographic girth weld inspection - X-ray crawlers and internal scanners running with computed radiography for fast digital results.
• Weld and coating inspection - visual and dimensional inspection, holiday detection, and coating assessment tied to the construction specification.
• Inline inspection support - dig verification and anomaly assessment for ILI runs.
• Integrity assessment - corrosion anomaly, dent, and crack evaluation with repair recommendations.

Equipment and crews

• Automated ultrasonic testing (AUT) systems with real-time data review
• Pipeline X-ray crawlers, internal X-ray scanners, and computed radiography
• Digital radiography review stations with on-site reporting
• Certified technicians qualified to API 1104 and the operator's specification, on rotation for continuous spreads

Why TechCorr

• Purpose-built mainline crews and equipment rather than adapted shop resources
• Digital records delivered per spread and per weld in the format your project controls group requires
• Crews mobilized from 14 locations for fast mobilization to the right-of-way
• NDT combined with pipeline integrity assessment, so weld and corrosion findings feed one engineering review

Talk to TechCorr before your next spread mobilizes: we match crew size, examination method, and reporting cadence to your construction schedule.
