17、tory note ISO 15590-3:2004, developed within ISO/TC 67 SC 2, has been taken over as a European Standard EN 14870-3 (ISO 15590-3:2004, modified). The scope of ISO/TC 67/SC 2 is pipeline transportation systems for the petroleum and natural gas industries without exclusions. However in CEN, the scopes

18、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 BT 38/1995: Subject: Revi

19、sed 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 of the materials, equipment and

20、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 standardization is to be achiev

21、ed 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 15590-3:2004 for the European adoption by CEN/TC 12. EN 14870-3:2006 (E) 4 Foreword This European Standard (EN 14870-3:2006) has been prepared by

22、Technical Committee CEN/TC 12 Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by end

23、orsement, at the latest by August 2006, and conflicting national standards shall be withdrawn at the latest by August 2006. The text of ISO 15590-3 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Sub

24、committee SC 2, Pipeline transportation systems. With respect to ISO 15590-3 the scope of this European Standard excludes on-land supply systems used by the gas supply industry. Attention is drawn to the possibility that some of the elements of this European Standard may be the subject of patent rig

25、hts. ISO and CEN shall not be held responsible for identifying any or all such patent rights.

EN 14870-3:2006 (E) 6 Introduction Users of this part of EN 14870 should be aware that further or differing requirements may be needed for individual

31、applications. This part of EN 14870 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 a

32、n alternative is offered, the manufacturer should identify any variations from this part of EN 14870 and provide details. EN 14870-3:2006 (E) 7 1 Scope This part of EN 14870 applies to weldneck and blind flanges (full face, raised face, and RTJ groove) as well as anchor, swivel-ring flanges and orif

33、ice flanges. This part of EN 14870 specifies the technical requirements for carbon steel and low-alloy steel forged flanges for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623. This part of EN 14870 designates those categories of flanges th

34、at meet the industrys need to match ISO 3183 pipe. These flanges are for normal and low-temperature service and include supplementary requirements where required for sour service. Materials for, or the attachment of, factory-welded extensions, bolting materials, gaskets, slip-on flanges or flanged f

35、ittings are not covered by this part of EN 14870. This part of EN 14870 is not applicable to integrally cast or forged flanges for valves, pumps or other equipment. This part of EN 14870 does not cover the selection of the flange category or pressure class. Sizes and pressure classes listed in ISO 7

36、005-1 and applicable to this part of EN 14870 are as follows: DN 10 (NPS 1/2) to DN 1500 (NPS 60); PN 20 (class 150), PN 50 (class 300), PN 100 (class 600), PN 150 (class 900), PN 250 (class 1500), PN 420 (class 2500). On-land supply systems used by the gas supply industry are excluded from the scop
