Indicador de Limite do Sistema de Pressão de Gás

Question

No ArcFM clássico, existe um campo que pode estar presente em várias classes de dispositivos, e sempre nas classes que possuem reguladores e válvulas, chamado GASPRESSURESYSTEMSTATUS, que indica se o dispositivo atua como um limite do sistema de pressão. Algumas empresas podem ter um campo com outro nome (como PARTITION) que recebe um nome de modelo para indicar que serve a esse propósito.<\/P> Presumo que exista um campo com propósito semelhante no UPDM, mas não consigo localizá-lo. Qualquer orientação seria muito apreciada.<\/P> Obrigado,<\/P> 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
