Another essential requirement of the operating license is ensuring economic costs of gas transportation and distribution. Consequently, UK gas infrastructu

28、the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). This European Standard is part of the series EN 12007 “Gas infrastructure Pipelines for maximum operating pressure up to and including 16 bar“ which comprises the following parts:
29、 Part 1 General functional requirements; Part 2 Specific functional requirements for polyethylene (MOP up to and including 10 bar); Part 3 Specific functional requirements for steel; Part 4 Specific functional requirements for renovation; Part 5 Specific functional recommendations of new service lin

32、es the general functional requirements for gas supply through service line pipe systems and covers the pressure range up to and including 16 bar maximum operating pressure (MOP). It gives normative and informative references for safe and secure gas infrastructures. It applies to their design, constr
33、uction, operation and the related aspects of safety, environment and public health, all in order to provide a safe and secure supply of gas. This European Standard is intended to be used in addition to the EN 12007 series of European Standards. The requirements of this European Standard are based on
34、 safe gas engineering practice under conditions normally encountered in the gas industry. Requirements for all unusual conditions cannot be specifically provided for, nor are all engineering and construction details prescribed. Existing industrial safety regulations applying to work areas, safety de
35、vices and safe work practices are not intended to be supplanted by this European Standard. Persons responsible for the design, construction and operation of gas infrastructures should have regard to the guidance given in this European Standard, the EN 12007 series of European Standards and to other
36、relevant standards. It is the responsibility of these persons to apply these functional requirements, supplemented with other proven good practice to the particular circumstances of each gas infrastructure. The recommendations in this European Standard are intended to be applied by competent persons
37、 who have suitable knowledge and experience. Notes in the text are informative. The designer, constructor or operator of service line and pipeline systems is cautioned that this European Standard is not a design handbook or code of practice. Additional national or company standards describing the de
38、tails are needed. These detailed standards should be in line with the basic principles of this European Standard. All pressures are gauge pressure unless stated otherwise. In preparing this European Standard it was recognised that the suite of relevant European Standards is incomplete. Reference may
39、 be made where appropriate to international, national or other standards until relevant European Standards are available.
