DIN EN ISO 16440:2017-07 EN ISO 16440:2016 (E)3 ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bod

26、ies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member 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

27、 non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are des

28、cribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

This document is not i

33、ntended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment, or engineering solutions for the individual application. This might be particularly applicable where there is innovative or developing technology. Where an alternative is offered, it is advisable that

34、the vendor identify any variations from this document and provide details.DIN EN ISO 16440:2017-07 EN ISO 16440:2016 (E)5 1 ScopeThis document specifies requirements, including corrosion protection, for the design, fabrication, installation and maintenance of steel-cased pipelines for pipeline trans

35、portation systems in the petroleum and natural gas industries in accordance with ISO 13623.NOTE 1 Steel casings can be used for mechanical protection of pipelines at crossings, such as at roads and railways and the installation of a casing at a highway, railway, or other crossing can be required by

36、the permitting agency or pipeline operator.NOTE 2 This document does not imply that utilization of casings is mandatory or necessary.NOTE 3 This document does not imply that cased crossings, whether electrically isolated or electrically shorted, contribute to corrosion of a carrier pipe within a cas

37、ed crossing. However, cased crossings can adversely affect the integrity of the carrier pipe by shielding cathodic protection (CP) current to the carrier pipe or reducing the CP effectiveness on the carrier pipe in the vicinity of the casing. Their use is not recommended unless required by load cons

38、iderations, unstable soil conditions, or when their use is dictated by sound engineering practices.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
