Gas infrastructure - Gas pressure control installations on service lines - Functional requirements
Abstract
This document contains the relevant functional requirements for gas pressure control installations that • are installed in or behind service lines according to EN 12007-5 in the gas infrastructure, and • are designed for maximum upstream operating pressure equal to or less than 16 bar, and • have a design flow rate equal to 2000 kW based on the gross calorific value or less. For gas pressure control installations which do not meet all the three criteria above, EN 12186 applies. Basic system requirements for gas pressure control installations are contained in this document. 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 control and measuring installations, the additional requirements of EN 1776 can apply. This document is applicable for gas pressure control installations in service lines for hydrogen, and hydrogen rich, and methane rich gases which are part of gas transmission or distribution systems. For gaseous fuels heavier than air additional considerations can be necessary. This document does not apply to gas pressure control installations in service lines in operation prior to the publication of this document. However, Annex D of this document can be used as guidance for the evaluation of installations in operation prior to the publication of this document, regarding the change of the type of gas, e.g. repurposing for the use with hydrogen. The objective of this document is to ensure the safe operation of such systems. 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. This document specifies common basic principles for the gas infrastructure. Users of this document should be aware that more detailed national standards and/or codes of practice can exist in the CEN member countries. This document is intended to be applied in association with these national standards and/or codes of practice setting out the above mentioned principles.
