Gas infrastructure. Pipelines for maximum operating pressure up to and including 16 bar. Part 5: Service lines. Specific functional requirements

Alkalmazási terület

This European Standard describes the specific functional requirements for service lines in addition to the general functional requirements of EN 12007-1 for: a) a maximum operating pressure (MOP) up to and including 16 bar; b) an operating temperature between -20 °C and +40 °C. It applies to their design, construction, commissioning, decommissioning, operation, maintenance, extension and other associated works. The service line is the physical asset comprising of pipework from the gas main branch saddle or top tee to the outlet of the distribution system operator’s nominated point(s) of delivery (for example: isolation valve, regulator, meter connection or combination of regulator and isolation valve). The ownership and operation responsibility can vary between member states. The extent of the service line can differ in each member state. To illustrate this, the various points of deliveries are indicated in Figure 1. Consult Figure 1 (A/B/C/D/E) and member state regulations and standards. NOTE The valve at point A is not necessarily utilised by each member state. National preference for points of deliveries should be stated in the national foreword. Ábra Specific functional requirements for: — polyethylene pipelines are given in EN 12007-2. — steel pipelines are given in EN 12007-3. — pipework for buildings are given in EN 1775. — pressure regulating installations are given in EN 12279 or EN 12186. — pressure testing, commissioning and decommissioning are given in EN 12327. This European Standard represents the recommendations at the time of its preparation. It does not apply retrospectively to installations before the publication date unless specifically stated. This European Standard specifies common basic principles for gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or code of practice may exist in the CEN member countries. This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this European Standard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts). CEN/TR 13737 (all parts) gives: — clarification of all legislations/regulations applicable in a member state; — if appropriate, more restrictive national requirements; — a national contact point for the latest information.
