ISO 19345-1:2019

1.1 This document specifies requirements and gives recommendations on the management of integrity of a pipeline system throughout its life cycle which includes design, construction, commissioning, operation, maintenance and abandonment.
1.2 This document is applicable to onshore pipeline systems used in transportation in the petroleum and natural gas industries, connecting wells, production plants, process plants, refineries and storage facilities, including any section of a pipeline constructed within the boundaries of such facilities for connection purposes. The extent of pipeline systems covered by this document is illustrated in Figure 1. This document does not deal specifically with the integrity of non-pipe elements. The pipeline segment between the wellsite and the gathering station, treatment plant or process plant (between Facilities 1 and 2 in Figure 1) is included in this document, though many mandatory elements of this document are not practical due to characteristics such as diameter, operating parameters, etc.
1.3 This document applies to rigid, steel pipelines. It is not applicable for flexible pipelines or those constructed from other materials, such as glass-reinforced plastics.
1.4 This document does not cover all conditions nor engineers' competency which might be related to pipeline integrity. The user can evaluate whether additional requirements are necessary.
1.5 This document is used for integrity management, which is initiated at the design and construction stage of the pipeline. Where requirements of a design and construction standard (e.g. ISO 13623) are different, the provisions of this document will enhance the design and construction from an integrity perspective.
