Protecting asset integrity across the full production and transportation lifecycle.
Insulated process piping and
equipment in oil and gas facilities are among the highest-risk CUI environments
in industry. The combination of operating temperatures in the CUI-active range,
frequent steam tracing and water ingress pathways, and the scale of insulated
piping circuits makes CUI both prevalent and difficult to manage without a
structured, multi-technique inspection programme.
Fired heaters, reformer tubes,
catalytic cracker pressure parts, and high-pressure separators operate at
conditions that exclude conventional UT inspection without shutdown. In-service
inspection at operating temperature is required to maintain corrosion
monitoring frequency between planned outages — demanding high-temperature UT
capability that most inspection providers cannot field.
Upstream and refining facilities
handling H2S-containing streams require steel qualification and in-service
assessment for hydrogen-induced cracking (HIC), stress-oriented HIC (SOHIC),
and sulphide stress cracking. Standard UT is insufficient for HIC characterisation
— immersion UT scanning to NACE TM0284 is required for reliable detection and
CLR/CTR/CSR quantification.
Transmission pipelines in oil and
gas require periodic inline inspection for internal metal loss and cracking,
supplemented by above-ground cathodic protection surveys for external corrosion
assessment. Integrating ILI data with DCVG/ACVG coating survey and ECDA
methodology provides the complete pipeline integrity picture that regulatory
and operator requirements demand.
Phased array UT and TOFD for
pressure vessel, piping, and nozzle weld inspection — delivering higher
probability of detection, superior sizing accuracy, and faster coverage than
conventional UT on the complex geometries common in oil and gas pressure equipment.
Pulsed eddy current, long-range
guided wave UT, and tangential profile radiography for non-intrusive screening
of insulated piping and equipment — identifying active CUI without full
insulation removal, and directing targeted window removal to the locations
where it is warranted.
ISO 17025-accredited immersion UT
scanning for HIC test sample evaluation to NACE TM0284, incoming material
qualification, and in-service HIC assessment on removed sour service steel
samples.
In-service UT thickness
measurement up to 550°C for fired heater tubes, reformer pressure parts, FCCU
hot walls, and other assets that cannot be cooled to conventional UT
temperature between planned outages.
MFL and UT intelligent pig inline
inspection for pipeline metal loss and crack detection, combined with DCVG/ACVG
coating survey and pipeline cleaning services as an integrated pipeline
integrity programme.
API 653 storage tank inspection
including MFL floor scanning, PAUT annular plate weld inspection, SLOFEC for
thick-wall and coated floors, and shell thickness survey.
