Australian Goverment Pipe Specifications
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 throught its entire length, do not use holes of different length than the pipe.
3. The I.D. (inside diameter)of all pipes shall 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 , fuel or other stuff can be put in it at a later date.
5. All pipes are to be supplied without rust, this can be more readily applied at the jobsite.
NOTE: Some vendors are now able to supply pre-rusted pipe, if available in your area this product is recommended as it wll save time on the jobsite.
6. All pipe over 500ft(153 meters) in length should have the words "long pipe" clearly painted on each end so that the contractor will know that it is a long pipe.
7. All pipe over 2 miles(3.2km) in length should have the words "long pipe" painted in the middle so that the contractor wll not have to walk the entire length of the pipe to determine if it is a long pipe or a short pipe.
8. All pipe over 6"(152mm) in diameter must have the words "large pipe" painted on it so the contracto will not mistake it for a small pipe.
9. Flanges must be used on all pipes. Flanges must have holes for bolts quite separate from the big hole in the middle.
10. When ordering 90 degree/45 degree or 30 degree elbows, be sure to specify right hand or left hand otherwise you will end up going the wrong way.
11. Be sure to specify to your vendor whether you want level, uphill or downhill pipe. If you use downhill pipe for going uphill the water will flow the wrong way.
12. All couplings should have either left hand or right hand threads, but do not mix the threads, otherwise as the coupling is being screwed on one pipe it is unscrewed from the other.
