I picked the following up on Russ Keplers engineering list. Jan-Eric is a well reconized writter on steam engines in Finland and has had several engine building articles published in Live Steam & Out Door Railroading.
I thought this very humorus and thought I pass it on.

Friends,
In these techological days, we must all remember always to use the proper materials.
Here are the very important specifications for Live Steam pipes:
Piping Specification 200.90.40.1 :
1. All pipe is to be made of a long hole, surrounded by metal 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 be made of acid-proof material.
5. O.D. of all pipe must exceed the I.D. Otherwise the hole will be on the
outside of the pipe. (However, if the outside diameter is smaller than the
inside diameter, this will make the hole easier to clean and polish.)
6. All pipe is to be supplied with nothing in the hole so that water, steam or
other stuff can be put inside at a later date.
7. All pipe is to be supplied free of rust, as this can be more readily put on at the jobsite.
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 cause lumps under the paint.
9. All pipe over 100 feet in length must have the words ?Long Pipe? clearly
painted on each end so that the fitter will know that it is long pipe.
10. Pipe over 200 feet in length must also have these words painted in the
middle so that the fitter will not have to walk the full length of pipe to
determine if it is long pipe or not.
11. All pipe over six inches in diameter is to have the words ?Large Pipe?
painted on it so that the fitter will not use it for small pipe.
12. All pipe fittings are to be made of the same size of hole as the pipe.
13. All pipe caps are to have the hole in the end facing the pipe,
but must be closed on the other end. Beware of caps that are the made the wrong way around! (About half of them are.)
