AUSTRALIAN GOVERNMENT PIPE SPECIFICATIONS
1. All pipe is to be made of a long hole, surrounded by metal or plastic centred 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: Some vendors are now able to supply
pre-rusted pipe. If available in your area, this product is recommended
as it will save a great deal of time on the job.
6. All pipe
over 500ft (153metres) in length whould 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 also 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 or a short pipe.
8. All pipe over 6 inches (125mm)
diameter must have the words LARGE PIPE painted on it so the contractor
will not mistake it for a small pipe.
9. Flanges must be used on all pipe. Flanges must have holes for bolts quite seperate 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 right hand or left hand threads, but do not mix the
threads otherwise as the coupling is being screwed on one pipe, it is
unscrewing from the other.
Kind Regards....
