Full title and description

St NACE 35100-2017 (2022) — NACE standard titled "In‑Line Inspection of Pipelines" (original edition 2017 with a corrected/reissued version published in 2022). The document provides guidance on the use, selection and interpretation of in‑line inspection (ILI) technologies for pipeline integrity programs.

Abstract

This standard reviews available and emerging in‑line inspection technologies, describes typical tool capabilities and limitations, and provides recommendations for decision making, operational preparation, data management and assessment of inspection results. It includes appendices covering glossary terms, typical specifications, launch/receive procedures and practical guidance for preparing and executing ILI campaigns.

Scope

The standard covers the technical scope of in‑line inspection for metallic pipelines: it examines types of ILI tools and sensors, their performance characteristics and limitations, decision‑making criteria for tool selection, operational considerations for planning and executing inspections (including launching and receiving), data handling and management, and methods for assessing and interpreting ILI results for integrity management purposes. It is intended to support pipeline operators and integrity teams in planning, contracting and evaluating ILI activities.

Key topics and requirements

• Overview of ILI tool types and sensing technologies (e.g., magnetic flux leakage, ultrasonic, geometry mapping).
• Tool performance, application limits and selection criteria for different pipeline conditions.
• Decision‑making process and cost/benefit considerations for scheduling ILI runs.
• Operational preparations: cleaning, launching/receiving procedures and safety considerations.
• Data management, processing, and reporting requirements for ILI results.
• Assessment of ILI findings: anomaly sizing, prioritization, and recommendations for direct examination or remediation.
• Appendices: glossary, typical specifications, preparation checklists and sample procedures.

Typical use and users

Primary users include pipeline integrity engineers, operators of oil & gas transmission and distribution systems, ILI service vendors, inspection engineers, regulators and consultants involved in pipeline integrity management. The standard is used to inform procurement/specification of ILI services, to guide inspection planning and to support interpretation of inspection results in integrity programs.

Related standards

Related documents and standards frequently referenced alongside this standard include earlier NACE editions (e.g., NACE 35100:2012), NACE/SP guidance documents for pipeline assessment, API recommended practices and ASME integrity management guidance (examples of cross‑referenced standards are listed in product catalog entries and bibliographies accompanying the NACE document). These related references support corrosion assessment, direct examination procedures and pipeline integrity management frameworks.
