IRISH GOVERNMENT 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 throughout the entire length - do not
|
|
use holes of different length that 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 the
|
|
water, steam or other stuff can be put inside at another date.
|
|
|
|
5. All pipe should be supplied without rust - this can be more
|
|
readily applied at the job site.
|
|
|
|
N.B. Some vendor 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 153m (500 ft) in length should have the words
|
|
"long pipe" clearly painted on each end, so that the Contractor
|
|
will know it is a long pipe.
|
|
|
|
7. Pip over 3.2 km ( 2 miles ) in length must have the words "long
|
|
pipe" painted in the middle, so that the Contactor 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 152mm (6") in diameter must have the words "large
|
|
pipe" painted on it so that 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 separate from the big hole in the middle.
|
|
|
|
10. When ordering 90 degrees, 45 degrees or 30 degrees elbow, be
|
|
sure to specify right 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. I you use downhill pipe for going
|
|
uphill, the water will flow the wrong way.
|
|
|
|
12. All coupling should have either right hand or left hand thread,
|
|
but do not mix the threads - otherwise, as the couple is being
|
|
screwed on one pipe it is unscrewed from the other.
