Piping Course

[amnoorulaman]

Dear Engineers,

I am Noorul Aman. I am a mechanical engineer in the field of PIPING AND CONST/ARCI.
Here I want to shear whatever I gather the information about engineering field with you.

Piping/Mechanical Design Drawings
GENERAL
The primary drawings that a Piping/Mechanical Field Engineer will use in the course of completing
a field assignment are:
· Piping and Instrument Diagram (P&ID)
· Piping Isometric
· Plot Plans
· Piping Class Sheets
· Piping Support Details and Hanger Drawings
· Vendor Drawings and Manuals
· Instrument and Tubing Drawings
· Standard Instrument Details
· Steam heat Tracing Drawings
These drawings along with project installation specifications provide quality guidelines for properly
completing the assigned system.

The single most important drawing for the installation of piping systems is the Piping and
Instrument Diagram (P&ID). It provides the base design description of the required pipe routing
and sizing, flow direction and slope, instrumentation and controls, insulation, heat tracing, and
equipment and/or instrument references. This provides a road map to finding other drawings,
vendor data, and piping information to properly complete the installation. The P&ID does not
however provide dimensional data or physical locations of any commodities.
The Piping Line List and the Instrument Index are issued documents which often provide this
information.

What is the difference between Pipe and Tube?
Ans: Pipe is identified by NB and thickness is defined by Schedule whereas Tube is
identified by OD.
