UPDM Squeeze Off-functies

EdwardBlair

Hallo -

Het UPDM-model lijkt squeeze-off gebeurtenissen weer te geven als functies in een niet-netwerkklasse (buiten het utility network). Onze huidige gegevens hebben squeeze-offs als eenvoudige knooppuntfuncties -- zodat deze locaties kunnen worden geïdentificeerd door een trace.

Zullen we functionaliteit verliezen als we onze huidige squeeze-offs migreren naar de UPDM, niet-genetwerkte, P_SqueezeOff klasse?

Bedankt,

Ed

Hi Ed,

In addition to Robert and Ayan's great comments, I do have one more for you. A P_SqueezeOff feature's purpose is to denote where the pipe has previously been subjected to the material stress of a clamp to "squeeze off" the flow of gas. The importance of this is to insure that a pipe is not squeezed more than once at a single location. If you are interested here is a document from Performance Pipe on best practice for polyethylene pipe squeeze-off.  The document specifies multiple constraints on where a squeeze can be applied. One of which is the location of a previous squeeze off. As such, it should never be used as a barrier feature in an isolation trace, as that would likely lead to field techs applying a 2nd squeeze off at a location where one should not occur. Managing the P_SqueezeOff data as a simple point feature outside of the Utility Network, accomplishes its purpose which is to convey the location where a field technician should not apply a squeeze off.
