 | All pipe is to be made of a long hole, surrounded by metal centered
around the hole. |
| All pipe is to be hollow throughout the entire length. |
| All pipe is to be the very best quality, preferably tubular or
pipular. |
| All acid-proof pipe is to be made of acid-proof metal. |
| The O.D. of all pipe must exceed the I.D., otherwise the hole will
be on the outside of the pipe. |
| 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. |
| All pipe is to be supplied without rust, as this can be more readily
put on at the jobsite. |
| All pipe is to be cleaned of coverings such as mud, tar, barnacles
or any form of manure before installation, otherwise it will make
lumps under the coating. |
| All pipe more than 500 feet in length must have the words "Long
Pipe" clearly painted on each end so that the fitter will know it
is long pipe. Pipe more than two miles in length must also have these
words painted on the middle of the length, so that the fitter will not
have to walk the full length of the pipe to determine if it is long
pipe or not. |
| All pipe more than 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. |
| All pipe closers are to be open at one end. |
| No fittings are to be put on the pipe unless specified. If you do,
straight pipe becomes crooked pipe. |
