In order to better serve our customers please observe the following list of pipe
recommendations for waterlines and similar while on site.
The following list is only offered as a
general guide for pipe selection:
1. All pipe is to be made of a long hole and surrounded by metal or plastic centered around the hole.
2. All pipe is to be holed 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. Pipe is to be supplied with nothing in the hole so that water, steam, etc. can be put inside at a later date.
5. All pipe is supplied without rust as the required amount can be easily applied at the job site. (Note: Some vendors are now able to
supply pre-rusted pipe. If available in your area, this new product may save time at the job site.)
6. Long pipe, over 500ft (153m), in length should have the words
"LONG PIPE" clearly painted on each end so crew will know it is
a long pipe.
7. Pipe over two miles (3,2 km) in length must also have the words
"LONG PIPE" painted in the middle so the crew will not have to walk the
entire length of the pipe to determine whether it is a long pipe or
short pipe.
8. Pipe over 6in (152mm) in diameter must have the words LARGE
PIPE painted on it so the crew will not mistake it for a small
pipe.
9. Flanges should be used on all pipe. Flanges must have holes of equal diameter for bolts. Flange holes must remain separate from the big hole in the middle.
10. When ordering 90 deg., 45 deg., or 30 deg. elbows be sure to
specify right-hand or left-hand bends, otherwise you will end up going in the
wrong direction.
11. Specify to your vendor whether you want level,
up-hill, or down-hill pipe. If you use down-hill pipe for going up-hill
the water will flow the wrong way.
12. All couplings should have either right-hand or left-hand
threads. Do not mix the threads. Mixed threads will cause a problem where as one coupling is being
screwed on the pipe it will be unscrewed from the other.
