T

18、he 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 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. Th

19、e conflict in scope was resolved when both the CEN/Technical Committees and the CEN/BT took the following resolution: Resolution 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 fo

20、r 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 offshore structures used in drilling, production, refining and the transport by pipelines of petroleum and natural gas, excluding on-land su

21、pply 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 achieved wherever possible by the adoption of ISO Standards.” Resulting from Resolution BT 38/1995, “gas supply on land“ has been excluded from th

22、e 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 Technical Committee CEN/TC 12 “Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries”, the s

23、ecretariat of which is held by AFNOR.

The text of I

24、SO 15590-3 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems. With respect to ISO 15590-3 the scope of this European Standard excludes on-land supply

25、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 rights.

This part of EN 14870 is not intended to inhibit a manufacturer from offering, or the purchaser from accepting, alternative

32、 equipment or engineering solutions for the individual application. This can be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the manufacturer should identify any variations from this part of EN 14870 and provide details. EN 14870-3:2006

33、 (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 orifice flanges. This part of EN 14870 specifies the technical requirements for carbon steel and low-alloy steel forged flanges for use in pi

34、peline transportation systems for the petroleum and natural gas industries as defined in ISO 13623. This part of EN 14870 designates those categories of flanges that meet the industrys need to match ISO 3183 pipe. These flanges are for normal and low-temperature service and include supplementary req

35、uirements where required for sour service. Materials for, or the attachment of, factory-welded extensions, bolting materials, gaskets, slip-on flanges or flanged fittings 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

36、, 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 7005-1 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),

37、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 scope of this document. 2 Normative references The following referenced documents are indispensable for the application of this document.
