Technical Resources for NDT Inspection and Integrity Management
Technical articles on API inspection, pipeline integrity, AUT/C-Scan, and Guided Wave/LRUT workflows. Use these notes to clarify field evidence, assessment inputs and report documentation.
01 / Article index
Field-to-report references.
Fifteen technical resources are available in this preview. The language is intentionally literal: inspection data, measurement references, assessment inputs and engineering review.
B31G vs Modified B31G vs RSTRENG: what each assessment method does
Compare B31G, Modified B31G and RSTRENG pipeline metal-loss assessments, their inputs, differences and role in qualified engineering review.
Read technical resourceWhat is ILI dig verification?
Learn what ILI dig verification records in the field, why direct examination is required and how verified measurements support pipeline anomaly assessment.
Read technical resourceHow to correlate ILI features with field UT measurements
A practical method for reconciling ILI feature locations and dimensions with field UT grids, stationing, odometer references and documented differences.
Read technical resourcePipeline anomaly assessment workflow from ILI to final report
Follow a documented pipeline anomaly workflow from ILI feature import through dig verification, assessment, repair documentation and final report compilation.
Read technical resourceWhat is HydroFORM corrosion mapping?
Understand encoded HydroFORM corrosion mapping, including C-Scan data, scan stitching, indication sizing, minimum wall thickness and corrosion profile outputs.
Read technical resourceAUT corrosion mapping vs manual UT grids
Compare AUT corrosion mapping and manual UT grid inspection for coverage, resolution, repeatability, documentation and appropriate use.
Read technical resourceHow C-Scan data is used to confirm ILI corrosion
Learn how encoded C-Scan evidence confirms or refines ILI-reported corrosion, including minimum wall and remaining-strength assessment inputs.
Read technical resourceAPI 570 inspection reporting workflow
A documented API 570 piping inspection reporting workflow covering CML/TML data, trending, corrosion rate, remaining life, drawings, photos and final compilation.
Read technical resourceAPI 510 pressure vessel inspection reporting workflow
A practical API 510 pressure vessel inspection reporting workflow for thickness readings, calculations, drawings, NDE evidence and final report compilation.
Read technical resourceAPI 653 tank inspection reporting workflow
A documented API 653 tank inspection reporting workflow for shell, roof and bottom data, CML/TML trends, drawings, photos and final compilation.
Read technical resourceHow corrosion rate and remaining life are calculated in mechanical integrity programs
Learn how short-term and long-term corrosion rates, remaining life and next-inspection inputs are calculated and reviewed in integrity programs.
Read technical resourceWhat is a CML and how should CML data be managed?
Understand condition monitoring locations and thickness monitoring locations, repeatable numbering, drawing linkage, history and data-management controls.
Read technical resourceGuided Wave / LRUT limitations inspectors and operators should understand
Understand what Guided Wave and LRUT screens for, the conditions that reduce data quality, detection limits, access constraints and prove-up needs.
Read technical resourceWhat CSC means in Guided Wave inspection
Learn what cross-sectional change means in Guided Wave inspection, how CSC is classified and why it is not a direct wall-loss measurement.
Read technical resourceSelecting Follow-Up Examination Methods After a Guided Wave / LRUT Indication
How to select the right follow-up examination after a Guided Wave / LRUT indication — screening versus characterization, localized UT and corrosion mapping, SRUT, EMAT and QSR, coverage and limitations.
