NF ISO 22974, M88-288 (07/2023)

This document specifies requirements and provides recommendations for assessing the integrity of pipelines for various applications in pipeline systems. This document applies primarily to onshore pipeline systems, well connections, production plants, processing plants, refineries and storage facilities, and any section of pipeline constructed within the limits of these installations for connection purposes in accordance with ISO 19345-1. These principles can also be used for offshore conduct as long as they are applicable and practical. This document also applies to rigid steel pipes. It does not apply to flexible pipes, nor to pipes made from other materials such as glass fiber reinforced plastic (GRP). This document does not cover all conditions that may be related to pipe integrity. A competent pipeline integrity engineer will be able to assess whether additional requirements are necessary. This document does not cover the assessment of pipe defect(s) found during manufacture/construction or installation, which shall be carried out in accordance with design, construction, procurement standards in materials and welding procedures applicable at that time. However, this document can be applied to the ongoing monitoring and assessment of defects known during construction.
