31、017 All rights reserved vii ISO 13623:2017(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each mem
32、ber body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International El
33、ectrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different type
34、s of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be
35、held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is informa
36、tion given for the convenience of users and does not constitute an endorsement. For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade Organization (WT
37、O) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html. This document was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline
38、transportation systems. This third edition cancels and replaces the second edition (ISO 13623:2009), which has been technically revised.viii ISO 2017 All rights reserved ISO 13623:2017(E) Introduction Significant differences exist between member countries in the areas of public safety and protection
39、 of the environment, which cannot be reconciled into a single preferred approach to pipeline transportation systems for the petroleum and natural gas industries. Reconciliation was further complicated by the existence in some member countries of legislation that establishes requirements for public s
40、afety and protection of the environment. Recognizing these differences, ISO/TC 67/SC 2 concluded that this document should allow individual countries to apply their national requirements for public safety and the protection of the environment. This document is not a design manual; rather, it is inte
41、nded for use in conjunction with sound engineering practice and judgment. This document allows the use of innovative techniques and procedures, such as reliability-based limit state design methods, providing the minimum requirements of this document are satisfied.

42、roleum and natural gas industries Pipeline transportation systems 1 Scope This document specifies requirements and gives recommendations for the design, materials, construction, testing, operation, maintenance and abandonment of pipeline systems used for transportation in the petroleum and natural g
43、as industries. It applies to pipeline systems on-land and offshore, connecting wells, production plants, process plants, refineries and storage facilities, including any section of a pipeline constructed within the boundaries of such facilities for the purpose of its connection. The extent of pipeli
44、ne systems covered by this document is illustrated in Figure 1. This document applies to rigid, metallic pipelines. It is not applicable for flexible pipelines or those constructed from other materials, such as glass-reinforced plastics. This document is applicable to all new pipeline systems and ca
45、n be applied to modifications made to existing ones. It is not intended that it applies retroactively to existing pipeline systems. It describes the functional requirements of pipeline systems and provides a basis for their safe design, construction, testing, operation, maintenance and abandonment.
