(Main)Industrial Gas Installation - Guideline
Industrial Gas Installation - Guideline
This Technical Report applies to safety and operational topics for equipment and pipework systems installed within industrial premises which may be used for process and non-process applications such as Heating, Power Generation, Incineration, etc.
It is applicable to a range of combustible gases used within an industrial environment. The gas plant may include normal combustion with air and/or oxygen, catalytic oxidation or cracking (e.g. as in a refinery).
The user of gas equipment and pipework systems has a responsibility to ensure the safety of the design, of plant operation and plant maintenance.
For piped supplies of gas to a site this Technical Report applies to the system downstream of the ‘point of delivery’. The term, ‘point of delivery’ refers to the isolation valve (or combination of regulator and isolation valve) located before or after the metering station, as will be defined by the particular EU member state national legislation.
The guidance in this Technical Report may also apply to gases generated for the sites own use, such as coke oven gas, site bio-gas plant, site LPG/air plant etc.

Installation gaz dans le domaine industriel - Lignes directrices
Le présent Rapport technique s’applique à la sécurité et aux aspects opérationnels des équipements et systèmes de tuyauterie installés sur des sites industriels et qui peuvent être employés pour des applications de procédés ou non, comme le chauffage, la production d’électricité, l’incinération, etc.
Il couvre une grande diversité de gaz combustibles utilisés en environnement industriel. L’usine à gaz peut employer des procédés de combustion normale à l’air et/ou à l’oxygène, d’oxydation catalytique ou de craquage (par exemple, dans le cas d’une raffinerie).
Il incombe à l’utilisateur d’équipements à gaz et de systèmes de tuyauterie de garantir la sécurité de la conception, de l’exploitation de l’usine et de l’entretien de l’usine.
Dans le cadre de l’approvisionnement en gaz d’un site par des canalisations, le présent Rapport technique s’applique au système en aval du « point de livraison ». Le terme « point de livraison » renvoie à la vanne de coupure (ou à l’ensemble régulateur et vanne de coupure) qui se trouve avant ou après la station de comptage, telle que définie par la législation nationale applicable à l’État-membre de l’UE concerné.
Les recommandations formulées dans le présent Rapport technique peuvent également s’appliquer aux gaz générés pour l’usage interne des sites, par exemple le gaz de cokerie, l’installation de biogaz du site, l’installation de mélange GPL/air du site, etc
Industrijska plinska napeljava - Smernica
To tehnično poročilo velja za varnostne vidike in vidike obratovanja za opremo in cevovodne sisteme, nameščene v industrijskih objektih, ki se lahko uporabljajo za namene procesov ali pa ne (kot so gretje, proizvajanje energije, sežiganje itd.).
Velja za vrsto vnetljivih plinov, ki se uporabljajo v industrijskem okolju. Naprava za uplinjanje lahko vključuje normalno zgorevanje z zrakom in/ali kisikom, katalitično oksidacijo ali razbijanje (npr. kot v rafinerijah).
Uporabnik opreme in cevovodnih sistemov za plin je odgovoren za zagotavljanje varnosti projektiranja, delovanja in vzdrževanja naprave.
Za dobavo plina po ceveh to tehnično poročilo velja za smer toka sistema do »točke dostave«. Izraz »točka dostave« se nanaša na ločilni ventil (ali kombinacijo regulatorja in ločilnega ventila) pred merilno postajo ali za njo, kot bo določeno v nacionalni zakonodaji posamezne države članice EU.
Navodila iz tega tehničnega poročila se lahko uporabljajo tudi za pline, proizvedene za lastno uporabo na lokacijah, kot so plin za koksarne, bioplinske naprave, obrat LPG/zrak.

Introduction
Gas industry leaders acknowledge the strategic role of European and National Standards in their efforts to
ensure the safety of gas installations in industrial premises. This Technical Report has been prepared to
explain to those involved with industrial premises some of the relevance of a range of Directives that affect
their operations. In addition guidance is given on the terms and definitions widely in use throughout the
European Union, together with some important information on how a consumer of gas can ensure safety in
operating their site. Minimizing the adverse effects on the environment is also an important consideration.
European and National legislation and the related framework of standards are complex and changing at an
ever increasing pace. For industrial plant engineers, finding the relevant standards can be a difficult task,
demands specific knowledge, and can consume a considerable amount of time. A number of the principal
standards are highlighted in this Technical Report, but EU Member States may have similar or equivalent
standards covering the application. Additionally, member states may have slightly different legal systems and
requirements that demand compliance.
Both designers and installers play an important role in applying the current standards for design, construction,
testing, commissioning and operation of all industrial gas installations. Safety is therefore improved and the
full energy efficiency potential of industrial thermal proce

European and National legislation and the related framework of standards are complex and changing at an

Both designers and installers play an important role in applying the current standards for design, construction,
testing, commissioning and operation of all industrial gas installations. Safety is therefore improved and the
full energy efficiency potential of industrial thermal processes can be utilized.
It is recognized that the main reference is this Technical Report is to Natural Gas but many standards equally
apply directly to LPG and LPG/Air mixtures. This Technical Report is also applicable to many bio-gases, and
other flammable gases, and the user will need to ensure they are aware of any different requirements needed
to ensure safety. For example some gases may be very hot or corrosive, some may be ‘wet’ and others may
