📋P&ID (piping and instrumentation diagram) 🔸is a detailed diagram in the process industry that shows the piping and process equipment together with the instrumentation and control devices. 🔸P&IDs also play a significant role in the maintenance and modification of the process after the initial build. 🔸P&IDs are originally drawn up during the design stage.We make some deliverables at the FEED stage (front-end engineering design) but have all process deliverables detailed at the detail engineering development stage. 🔸The coordination of piping, instrumentation, electrical, and Process safety engineers is responsible for designing P&ID. ✏️Information we gain from P&ID: 🔹Line number, Line size, and Specification of the piping system. 🔹The flow direction of lines. 🔹All valves (Type of valve and identification of any special type of valve). 🔹Details about high-point vent (HPV), low-point drain (LPD), Special fittings, sampling points, reducers, spectacles, blinds, etc. 🔹permanent start-up and flush lines. 🔹Name and number of all equipment. 🔹Equipment-to-equipment connection details. 🔹Instrument name and number in a piping system. 🔹All control loops (Basic control loops and Advanced control loops). 🔹Insulation or Jacketing requirements. 🔹Vendor and contractor interfaces. 🗞️Limitations of P&ID: ▪️As P&ID is not drawn on a scale, it is unable to give you the exact dimensions of any piping system. ▪️Process conditions, Operation conditions, and Physical data can't be obtained from it. ▪️Equipment location can't be determined with the help of P&ID. ▪️The line route, length, fittings, supports, and structural details used for the piping network can't be determined. 💡We can get all this data from another drawing, like PFD, Isometric or 3D modelling.

Great share.
Helpful knowledge
Well said
the good ol' days! P&ID is one of my favorite things in the world
