METAL.
OUTSIDE DIAMETER (O.D.) OF ALL PIPE MUST EXCEED THE
INSIDE DIAMETER (I.D.) OTHERWISE, THE HOLE WILL BE ON THE
OUTSIDE.

3. 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.
• ALL PIPE IS TO BE SUPPLIED
WITHOUT RUST, AS THIS CAN
BE MORE READILY PUT ON AT
JOBSITE.
• ALL PIPE IS TO BE CLEANED

ANY FORM OF MANURE
BEFORE PUTTING UP.
OTHERWISE, IT WILL MAKE
LUMPS UNDER THE PAINT.

OPEN ON ONE END.

MUST GO SOMEWHERE AND
CONNECT TO SOMETHING. THE
FITTER IS REQUIRED TO VERIFY
THIS BEFORE TURNOVER.

4. ALL PIPE OVER 500 FOOT LONG MUST HAVE WORDS “LONG
PIPE” CLEARLY PAINTED ON EACH END SO THAT THE FITTER(S)
WILL KNOW THAT IT IS LONG PIPE.
• PIPE OVER TWO MILES

WORDS “LONG PIPE”
PAINTED IN THE MIDDLE
SO THAT THE FITTER(S)
WILL NOT HAVE TO WALK
THE FULL LENGTH OF PIPE
TO DETERMINE IF IT IS
LONG PIPE OR NOT.
• ALL PIPE OVER 12 INCHES
IN DIAMETER IS TO HAVE
THE WORDS “LARGE PIPE”
PAINTED ON IT, SO THAT
