What pipeline inspection actually covers

Assets in scope: transmission and gathering lines, girth and seam welds, pump and compressor stations, road and rail crossings, river crossings, and above-ground installations.

Damage mechanisms that drive the inspection plan

External corrosion under disbonded coating and at holidays; internal corrosion at low points and water accumulation; stress corrosion cracking, both high and near-neutral pH; manufacturing defects in older seam welds; third-party mechanical damage; and geotechnical strain in unstable ground.

Methods applied

In-line inspection using MFL, ultrasonic and crack-detection tools; guided wave for cased and inaccessible sections; direct assessment excavation with ultrasonic and magnetic particle at the dig; close interval potential survey and DCVG for coating and cathodic protection condition; and automated ultrasonic testing on new girth welds.

Governing codes and standards

API 1104 for girth welding, ASME B31.4 and B31.8 for design and operation, ASME B31.8S for integrity management, NACE/AMPP standards for corrosion control, and the applicable regulator's integrity management requirements.

What makes this sector different

Integrity decisions rest on fusing in-line inspection data with cathodic protection and coating survey data and with dig verification. The recurring failure is treating each dataset separately, which produces dig programmes that verify the tool rather than manage the risk.

The Chicago asset base

Chicago anchors a major US Midwest industrial belt, with the BP Whiting Refinery (440,000 bpd — the largest in the Midwest) just across the Indiana border, the ExxonMobil Joliet Refinery (250,000 bpd), CITGO Lemont (170,000 bpd), and Marathon Robinson (245,000 bpd in adjacent Illinois). Caterpillar's regional manufacturing, US Steel's Gary Works, and the Argonne National Laboratory engineering oversight all drive inspection demand. PHMSA pipeline integrity across the Enbridge Mainline corridor through Illinois, OSHA PSM, and the Illinois EPA frame a compliance environment ideally suited to digital twin programmes.

How the work is controlled

Agree personnel qualification, equipment checks, procedure revision and review responsibilities for the examination. Retain those records with the results and coverage limitations.

Pipeline NDT beyond Chicago
