P&ID(Piping & Instrumentation Diagram)

Introduction

Bambang HNTripatra, 1 Sept 2014

ObjectiveUnderstand how to read P&ID properly, so every discipline can do self-check data given by process and do self-check conformity of P&ID with their works.

P&ID Content

P & I should be included not limited to :

• All process equipment identified by equipment number

• All pipes identified by a line number. Pipe size and material of construction should be shown

(material may include as a part of the identification number)

• All valves with an identification no. along with their type & size should be shown

• Ancillary fittings that are part of piping system such as inline sight glasses, strainers and stream

traps with an identification no.

• Pumps identified by a suitable code no.

• All control loops and instruments with identification

P&ID ContentP&ID do not show:• Scale to equipment dimension (NTS)

• Nozzle elevation and orientation
