Indicateur de Limite du Système de Pression de Gaz

Question

Dans ArcFM classic, il existe un champ qui peut être présent sur plusieurs classes d'appareils, et toujours sur les classes qui contiennent des régulateurs et des vannes, nommé GASPRESSURESYSTEMSTATUS, qui indique si l'appareil agit comme une limite du système de pression. Certaines entreprises peuvent avoir un champ avec un autre nom (comme PARTITION) auquel un nom de modèle est attribué pour indiquer qu'il sert à cet effet.<\/P> Je suppose qu'il existe un champ avec un but similaire dans UPDM, mais je n'arrive pas à le localiser. Toute orientation serait grandement appréciée.<\/P> Merci, Ed<\/P>

Hi Tom -

This is a really good point. I will need to check further into the legacy
data.

Thx,
Ed

Hi Ed,

Controllable valves rarely sit on the edge between two pressure zones of different pressures.  To allow a technician to open a controllable valve on the edge of two differing pressure zones, puts the equipment and customers within the lower pressure zone at risk of over-pressurization and system failure.

Within the natural gas industry there are some who refer to Regulators as Pressure Reducing Valves.  Since these are two terms referring to the same type of device, within UPDM we refer to these devices only as Regulators.

Is it possible your legacy dataset, has generically classified a regulator as a valve?

Hi Tom -

Thanks for the detailed response.   With this the path for regulator configuration is clear.

However, what of valves that sit between two pressure systems?  Are there expectations about asset group/asset type assignments for such valves?

Thanks again,

Ed
