Rakesh,
You must be going by your memory........I suggest you don't. This newbie is banking on your words.
:PIPE : Designated by Nominal Pipe Size, Schedule No, etc.
1.) up to 12" - Nominal size is neither OD nor ID.
2.) 14" and larger- Nominal pipe size is equal to pipe OD. All that's changing is the
wall thickness and correspondingly changing
the ID.
:TUBE : Designated by OD and wall thickness
1.) OD is constant. All that's changing is the wall thickness and correspondingly changing the ID.
This is a very generalized subject, I suggest to "darushman47" to get
to the internet and search
for "tube" & "pipe".

Hi,
In Pipes, OD of pipe remains same upto 14" and thickness of pipe varies which further results in change in ID. Pipes are represented by Nominal Bore. Schedule / Thickness and NB/NPS is required for ordering of pipes.
In Tubes, ID remains same and OD varies with change in Thickness. ID and
Thk requires for ordering of tubes. Tubes are generally available upto
8"
size. These are mainly used for Instrumentation purpose.
I hope this will be useful to you.
regards,
