1. what is P and I D drawing?
- A piping and instrumentation diagram is a visual representation of a process system that includes the piping, vessels, control valves, instrumentation, and other process components and equipment in the system.
- In other words, It is a diagram which shows the interconnection of process equipment, and the instrumentation used to control process.
- The symbols contained in P and ID represent equipment such as actuators, sensors and controllers. Process tools such as valves, instruments, and pipelines are identified by code.
The codes are based on the size, type of fluid being drained, type of pipe connection such as using Bolt or Flange, and the status of the Valve such as Normally Close or Normally Open.

2. How to read P & ID?
- There are the few common piping or connection lines, which is used in P and ID drawing.
- For example, any electrical signal is represented by dotted line.
- And solid line represents straight line pipe.

P & ID Codes Or Symbols:
-In P & ID Codes(symbol), First letter represents parameters that are being controlled or monitored. For Example, it may be Flow, Level, Temperature ,or Pressure.
- Next Letter indicates types of control device being used for measurement. For example, It may be Transmitter, Valve, or Controller.
- Bottom Number is logical numerator. And It is used for identification of equipment.
- Circle with no line indicates that, Level Transmitter number zero zero three is mounted in the field area.
-Logical numerator or Numbered is very useful to identify equipment, when diagram has same equipment more than one.
How to identify instrument location from symbol?
- Circle with no line indicates that, instrument is mounted in the field area.
- And circle with dotted line indicates that, instrument is mounted in control room.
- Lastly, circle with solid line indicates that, instrument is not directly accessible.
