ISO 15590-12001, developed within ISO/TC 67 SC 2, has been adopted as EN 14870-12004 ISO 15590-1 2001 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 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 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 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 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 15590-1 2001 for the European adoption by CEN/TC 12. EN 14870-12004 E 4 Foreword The text of ISO 15590-12001 has been prepared by Technical Committee ISO/TC 67 “Materials, equipment and offshore structures for petroleum and natural gas industries” of the International Organization for Standardization ISO and has been taken over as EN 14870-12004 by 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of an identical text or by endorsement, at the latest by April 2005, and conflicting national standards shall be withdrawn at the latest by April 2005. International Standard ISO 15590-1 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum and natural gas industries, Subcommittee SC 2, Pipeline transportation systems. EN 14870 consists of the following parts, under the general title Petroleum and natural gas industries Induction bends, fittings and flanges for pipeline transportation systems Part 1 Induction bends Part 2 Fittings Part 3 Flanges According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 14870-12004 E 5 Introduction Users of this part of EN 14870 should be aware that further or differing requirements may be needed for individual 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 an alternative is offered, the manufacturer should identify any variations from this part of EN 14870 and provide details. EN 14870-12004 E 6 1 Scope This part of EN 14870 specifies the technical delivery conditions for bends made by the induction bending process for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623. This part of EN 14870 is applicable to induction bends made from seamless and welded pipe of unalloyed or low-alloy steels. This part of EN 14870 specifies three classes of induction bend corresponding to increasing quality requirements in accordance with the technical delivery conditions of ISO 3183 for pipe as indicated in Table 1 see also ISO 3183-31999, Introduction. Table 1 Induction bend class and corresponding pipe standard Induction bend class Corresponding pipe standard Class A ISO 3183-1 Class B ISO 3183-2 Class C ISO 3183-3 This part of EN 14870 is not applicable to the selection of the induction bend class. This part of EN 14870 is not applicable to pipeline bends made by other manufacturing processes. On-land supply systems used by the gas supply industry are excluded from the scope of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
