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 - do not use holes of different length than the pipe.
3. The I.D. (inside diameter) of all pipe must not exceed the O.D. (outside diameter) - otherwise the hole will be on the outside.
4. 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.
5. All pipe should be supplied without rust - this can be more readily applied at the job site. Note to purchasing agents: Some Vendors are now able to supply pre-rusted pipe. If available in your area, this product is recommended as it will save a lot of time on the job site.
6. All pipe over 500ft (153m) in length should have the words "long pipe" clearly painted on each end, so the Contractor will know it is a long pipe.
7. Pipe over 2 miles (3.2km) in length must have the words "long pipe" painted in the middle, so the Contractor will not have to walk the entire length of the pipe to determine whether or not it is a long pipe.
8. All pipe over 6" (152mm) in diameter must have the words "large pipe" painted on it, so the Contractor will not mistake it for small pipe.
9. Flanges must be supplied on all pipe. Flanges must have holes for bolts quite separate from the big hole in the middle.
10. All elbows 90 degrees, 45 degrees or 30 degrees will be clearly marked right hand or left hand to insure installers will not end up going the wrong way.
11. All pipe will be supplied in three versions: level, uphill or downhill pipe . Note to purchasing agents. Take care to specify when ordering. If downhill pipe is use for going uphill or uphill pipe for going downhill, the water will flow the wrong way.
12. All couplings should have either right hand or left hand thread, but do not mix the threads - otherwise, as the coupling is being screwed on one pipe, it is unscrewed from the other.
13. All pipe has to have identifying labels stating the name of the manufacturer, type, model, dimension and regulatory approval seal painted or embossed on the outside in a size that is easily read without magnification or instrumentation, for the entire length of the pipe. No labels shall be applied to the inside (hole side) of the pipe.
