This standard describes 3-in. through 64-in. (80-mm through 1,600-mm)
ductile-iron compact fittings to be used with ductile-iron pipe or pipe made of other
materials with similar outside diameters for conveying potable water, wastewater
and reclaimed water. Minimum working pressures by size range are as follows: 3 in.
through 24 in. (80 mm through 600 mm): 350 psi (2,413 kPa); 30 in. through
48 in. (750 mm through 1,200 mm): 250 psi (1,724 kPa); and 54 in. through 64 in.
(1,400 mm through 1,600 mm): 150 psi (1,034 kPa). Fittings are adequate for the
rated working pressure plus a surge allowance of 100 psi or a surge allowance of half
the rated working pressure, whichever is less.
Fittings with mechanical joints are listed in this standard for the 3-in. through
48-in. (80-mm through 1,200-mm) sizes. The standard also may be used for
fittings of these sizes with push-on joints or other joints as agreed on at the time
of purchase.
Fittings with push-on joints and flanged joints are listed in this standard for
the 54-in. through 64-in. (1,400-mm through 1,600-mm) sizes. Fittings with flange
joints are not discussed in this standard for sizes 3 in. through 48 in. (80 mm through 1,200 mm) because of the importance of standardized center-to-flange face dimensions
for these sizes already described in ANSI/AWWA C110/A21.10.
Fittings with plain ends are listed for bends and reducers of the 3-in. through
64-in. (80-mm through 1,600-mm) size range and for tees and crosses of the 54-in.
through 64-in. (1,400-mm through 1,600-mm) size range. Major revisions to this edition of the standard are quite extensive and can be found in the foreward section.
