EN 12186:2014
(Main)Gas infrastructure - Gas pressure regulating stations for transmission and distribution - Functional requirements
General Information
- Abstract
This European Standard contains the relevant functional requirements for gas pressure regulating stations, which form part of gas transmission or distribution systems. It is applicable to the design, materials, construction, testing, operation and maintenance of gas pressure regulating stations.
This European Standard does not apply to gas pressure regulating stations commissioned prior to the publication of this standard.
The stations covered by this European Standard have a maximum upstream operating pressure which does not exceed 100 bar. For higher maximum upstream operating pressures this standard should be used as a guideline.
If the inlet pipework of the station is a service line and the maximum upstream operating pressure does not exceed 16 bar and the design flow rate is equal to or less than 200 m3/h under normal conditions, EN 12279 applies.
Basic system requirements for gas pressure regulating stations are contained in this European Standard. Requirements for individual components (valves, regulators, safety devices, pipes, etc.) or installation of the components are contained in the appropriate European Standards.
NOTE For combined regulating and measuring stations, the additional requirements of EN 1776 can apply.
The requirements in this European Standard do not apply to the design and construction of auxiliary facilities such as sampling, calorimetering, odorization systems and density measuring. These facilities are covered by the appropriate European Standards, where existing, or other relevant standards.
The requirements of this European Standard are based on good gas engineering practice under conditions normally encountered in the gas industry. Requirements for unusual conditions cannot be specifically provided for, nor are all engineering and construction details prescribed.
The requirements in this European Standard are based on the physical and chemical data of gaseous fuels – including non-conventional gases – in accordance with Table 1 of EN 437:2003+A1:2009 for first and second family gases. Additional requirements in the case of gaseous fuels heavier than air and/or sour gases are not covered by this European Standard.
The objective of this European Standard is to ensure the safe operation of such stations. This does not, however, relieve all concerned of the responsibility for taking the necessary care and applying effective quality management during the design, construction and operation.
