ID controlled pipe is where the inside diameter remains constant and OD controlled pipe is where the ouside diameter remains constant. Please see : http://en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

http://en.wikipedia.org/wiki/Nominal_Pipe_Size

Pipe:

1. All pipe is to be made of a long hole, surrounded by metal or plastic centered around the hole.

2. All pipe is to be hollow throughout the entire length.

3. All pipe is to be of the very best quality, preferably tubular or pipular.

4. All acid-proof pipe is to made of acid-proof metal.

5. The O.D. (outside diameter) of the pipe MUST EXCEED the I.D. (inside diameter) otherwise the hole will be on the outside of the pipe.

6. All pipe is to be supplied with nothing inside the hole so water, steam, or other stuff can be put inside the pipe at a later date.

7. All pipe is to be supplied without rust, as this can be more readily put on at the job site.

8. All pipe is to be free of any covering such as mud, tar, barnacles or any form of manure before putting up, otherwise it will make lumps under the paint.

9. All pipe over 500 feet in length must have the words "Long Pipe" clearly painted on each end so the fitter will know it is a long pipe.

10. Pipe over two miles long must also have "Long Pipe" painted in the middle so the fitter will not have to walk the entire length of the pipe to determine if it is a long pipe or not.

11. All pipes over six inches in diameter is to have the words "Large Pipe" painted on so the fitter will not use it for a small pipe.

12. All pipe closures are to be open on one end.

13. All pipe fittings are to be made of the same stuff as the pipe.

On a serious note pipe schedule affects the OD of pipe also. OP can Google it if they're curious.

Thanks anyway. I've used that before so maybe the OT'r didn't want me to get credit twice.

Pipes are normally specified By diameter (outer or internal Depending on buyers choice) and wall thickness,If Internal diameter is critical for your applications You will specify ID +/- xx *thickness +/-xx and if your require controlled OD you will specify it OD+/-XX*thickness+/-xx.

There may be different manufacturing process and tools those can produce pipes with better control on ID or OD.

Wouldn't it be funny if the OP meant electrical conduit all this time.

ID vs OD Pipe-Power. I mean to say that, Normally the pipes used in Power Industries are based on ID.

Is there any specific reason other than this. Power Industry uses High Temp. and Pressure and in more critical applications.

By Pipe-Power I means that ID controlled pipes are normally used in Power sector. You are very right that it depends on Application whether it is critical or not. Could you elaborate this with some examples?

"pme",

I have been in the "Piping" world for more than 50 years and I have never heard the term "ID controlled pipe and OD controlled pipe".

Where did you see or hear this?

And what was the context at the time when this term was being used?

Also are you a trained and experienced Piping Professional?

or ---

are you a novice, or Student who has heard something but you have not read the text book or done any real research?
