PDS piping specialty equipment model
Thread Content
When creating equipment models for PDS piping systems, is it necessary to draw the instrument ports of the equipment?
Yes, materials are needed for those bolt washers as well
Yes, as mentioned above: 1. The pipe connections in the equipment modeling must match those listed in the engineering drawings; 2. There are valves and other components provided by the pipes on many instrument pipelines, and these need to be modeled as well
Reply to 2# tuliplt: Thank you. Regarding your answer, I have two more questions: 1. Shouldn’t the material for the instrument be provided separately by the instrument specialists? If the piping specialty is added, will there be duplication? 2. Is the main purpose of installing instrument ports in the piping discipline to check for collisions? Not for the instrumentation major, right? Because I’ve seen in many PDS models that the equipment itself doesn’t have any instruments; only the pipeline instruments are present.
Same question: if material is to be discharged from the gauge port on the equipment, does a pipe number also need to be assigned? If there is no tube number, then there will be no single-line diagram, and the materials will simply be included in the summary table ； The same problem can occur at interfaces such as sampling valves; how is it usually handled?
Reply to 5# luckyblue: There are regulations regarding specialized responsibilities to avoid duplicate counting. Under normal circumstances, the bolts and gaskets required for the instruments connected to the equipment outlets are provided and accounted for by the piping specialty; this can be indicated using a trim miscellaneous code, with the specific code being determined by the project
Draw a gauge component; assume it either already exists or there is no MTO, so that the bolt washers will be available and the gauge won’t come out
