This document is applicable for transporting gas via onshore high-pressure steel pipeline infrastructures, where the following applies:
-   onshore:
-   from the point where the pipeline first crosses what is normally accepted as battery limit between onshore and offshore, and that is not located within commercial or industrial premises as an integral part of the industrial process on these premises except for any pipelines and facilities supplying such premises;
-   pipeline system with a starting point onshore, also when parts of the pipeline system on the mainland subsequently cross fjords, lakes, etc.
-   high pressure: gas with a maximum operating pressure over 16 bar and a design temperature between −40 °C and 120 °C.
-   steel pipeline infrastructure: infrastructure consisting of pipeline components, such as pipes, valves, couplings and other equipment, restricted to components made of unalloyed or low alloyed carbon steel and joined by welds, flanges or mechanical couplings.
-   gas: non-corrosive natural gas, biomethane gas, hydrogen gas and mixtures of these gases where technical evaluation has ensured that operating conditions or constituents or properties of the gas do not affect the safe operation of the pipeline.
Gas infrastructures covered by this document begin after the gas producer's metering station.
NOTE 2   The functional demarcation of the pipeline system is usually directly after an isolating valve of the installation, but can differ in particular situations. The functional demarcation of the pipeline system is usually located on an isolating valve of the installation, but can differ in particular situations.

Gas Infrastructure - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial installations and greater than 5 bar for industrial and non-industrial installations - Part 1: Detailed functional requirements for design, materials, construction, inspection and testing
SIST EN 15001-1:2023

This European Standard specifies detailed functional requirements for the design, selection of materials, construction, inspection and testing of:
-   industrial gas installation pipework and assemblies with an operating pressure greater than 0,5 bar; and
-   non-industrial gas installation pipework (residential and commercial) with an operating pressure greater than 5 bar in buildings;
starting from the outlet of the network operator’s point of delivery up to the inlet connection to the gas appliance; normally the inlet isolation valve. This standard also covers the pipework to the inlet connection of a gas appliance that is not included within the scope of the appliance standard.
NOTE 1   The use of the term installation and pipework is interchangeable.
Apart from the exceptions stated below, this standard applies to gas installations operating at ambient temperatures between −20 °C and 40 °C and operating pressures up to and including 60 bar. For operating conditions outside these limitations, reference should additionally be made to EN 13480 (all parts) for metallic pipework.
For industrial gas installations up to and including 0,5 bar and for non-industrial (residential and commercial) gas installations up to and including 5 bar in buildings, EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this standard applies.
In this European Standard, the term “gas“ refers to combustible gases, which are gaseous at 15 °C and 1 013 mbar absolute atmospheric pressure (normal conditions). These gases are commonly referred to as manufactured gas, natural gas or Liquefied Petroleum Gas (LPG). They are also referred to as first, second or third family gases as classified in EN 437:2003+A1:2009, Table 1. The given values are considered as normal conditions for all volumes given in this standard.
This European Standard is applicable to installation pipework for the carriage of:
-   processed, non-toxic and non-corrosive natural gas according to EN 437:2003+A1:2009 and EN 16726 "Gas infrastructure - Quality of gas - Group H";
-   vaporized LPG;
-   biomethane, complying with EN 16723 1;
-   vaporized LNG.
NOTE 2   The specification of vaporized LNG is equal to that of natural gas as classified in EN 437:2003+A1:2009.
This European Standard does not cover pipework for hydrogen rich gases that fall outside the definitions within EN 437:2003+A1:2009.
LPG storage vessels (including all ancillaries fitted directly to storage vessels) are excluded. Also excluded are LPG installations and sections of LPG installations operating at vapour pressure in the liquid state (e.g. between the storage vessel and any pressure regulator).
In this standard, all pressures are gauge pressures unless otherwise stated.
This standard has been harmonized to address the essential safety requirements of the Pressure Equipment Directive (PED, 2014/68/EU [formerly 97/23/EC]) relevant for the joining of gas installation pipework (assemblies) falling within the scope of the PED. These are listed in Annex ZA. However, "this Directive does not cover the assembly of pressure equipment on the site and under the responsibility of the user, as in the case of industrial installations" (PED, Preamble, 7th recital, last paragraph).
Although in this respect, the standard takes into account the essential safety requirements of the PED, no inference can be drawn from this as to whether or not the installation or parts of the installation falls within the scope of the PED. Reference should therefore be made to the PED and relevant national legislation.
This European Standard specifies common basic principles for gas supply systems. Users of this European Standard should be aware (...)
