DIYbanter - Government Pipe Spec's (OT)

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.

N.B. 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 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 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 thread, but do not
mix the threads - otherwise,
as the coupling is being
screwed on one pipe, it is
unscrewed from the other.
