18、N 14870-2:2004 (E) 3 Explanatory Note ISO 15590-2:2003, developed within ISO/TC 67 SC 2, has been taken over as a European Standard EN 14870-2 (ISO 15590-2:2003 modified). The scope of ISO/TC 67/SC 2 is pipeline transportation systems for the petroleum and natural gas industries without exclusions.
19、However in CEN, the scopes of CEN/TC 12 and CEN/TC 234 overlapped until 1995.This scope overlap caused problems for the parallel procedure for the above-mentioned items. The conflict in scope was resolved when both the CEN/Technical Committees and the CEN/BT took the following resolution: Resolution
20、 BT 38/1995: Subject: Revised scope of CEN/TC 12 “BT endorses the conclusions of the coordination meeting between CEN/TC 12 “Materials, equipment and offshore structures for petroleum and natural gas industries” and CEN/TC 234 “Gas supply” and modifies the CEN/TC 12 scope, to read: “Standardization
21、of the materials, equipment and offshore structures used in drilling, production, refining and the transport by pipelines of petroleum and natural gas, excluding on-land supply systems used by the gas supply industry and those aspects of offshore structures covered by IMO requirement (ISO/TC 8). The
22、 standardization is to be achieved wherever possible by the adoption of ISO Standards.” Resulting from Resolution BT 38/1995, “gas supply on land“ has been excluded from the scope of ISO 15590-2:2003 for the European adoption by CEN/TC 12. Equivalence with European Standards is provided in Annex ZA.

30、cations. This document is not intended to inhibit a manufacturer from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This can be particularly applicable where there is innovative or developing technology. Where an alternative
31、 is offered, the manufacturer should identify any variations from this document and provide details. Licensed Copy: Wang Bin, na, Thu Apr 07 08:07:20 BST 2005, Uncontrolled Copy, (c) BSIEN 14870-2:2004 (E) 6 1 Scope This document specifies the technical delivery conditions for unalloyed or low-alloy
32、 steel seamless and welded pipeline fittings for use in pipeline transportation systems for the petroleum and natural gas industries as defined in EN 14161. This document is applicable to welding-end fittings such as elbows, caps, tees, single or multiple extruded headers, reducers, and transition s
33、ections made from seamless and welded pipe of unalloyed or low-alloy steels. This document specifies three classes of fitting corresponding to increasing quality requirements in accordance with the technical delivery conditions of ISO 3183 for pipe as indicated in Table 1. Table 1 Fitting class and
34、corresponding pipe standard Fitting class Corresponding pipe standard Class A ISO 3183-1 Class B ISO 3183-2 Class C ISO 3183-3 This document is not applicable to the selection of the fitting class. This document is not applicable to the materials for, or the attachment of, factory-welded extensions.
