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
