ANSI AWWA C110 pdf download.DLICTILE-IRON AND GRAY-IRON FITTINGS, 3 IN. THROUGH 48 IN.,FOR WATER AND OTHER LIQUIDS
ANSI AWWA C110 covers 3- 48 in. gray-iron and/or ductile-iron fittings to be used with ductile-iron pipe for water and other liquids. Specifications for fittings with mechanical joints and flanged joints are listed in the tables at the end of this standard. This standard may also be used for fittings with push-on joints or such. other joints as may be agreed on at the time of purchase. For the 3- 24 in. size range, ductile-iron mechanical-joint fittings and ductile- iron push-on joint fittings are rated for 350 psi (2.41 MPa) working pressure; ductile- iron flange-joint fittings are rated for 250 psi (1.72 MPa) working pressure; and gray- iron fittings having all types of joints covered by this standard are rated for 150 or 250 psi (1.03 or 1.72 MPa) working pressures. as shown in the tables. For the 30- 48 in. size range, fittings with all types of joints covered by this standard are shown in the tables as gray iron and/or ductile iron for rated working pressures of 150 or 250 psi (1.03 or 1.72 MPa), as shown in the tables.
10-9.1 Outside coating. The outside coating for general use under all normal conditions shall be a petroleum asphaltic coating approximately 1 mil (25 μm) thick. The coating shall be applied to the outside of all fittings, unless otherwise specified. The finished coating shall be continuous, smooth, neither brittle when cold nor sticky when exposed to the sun, and strongly adherent to the fitting. 10-9.2 Cement-mortar linings. Cement-mortar linings shall be in accordance with ANSIAWWA C1 04/A21.4. If cement-mortar linings are to be furnished, they shall be specified in the invitation for bids and on the purchase order.* Unless other- wise specified, moist cement-mortar linings are given a seal coat of asphaltic material for curing of the cement mortar. 10-9.3 Inside coating. Unless otherwise specified, the inside coating for fittings that are not cement lined shall be a petroleum asphaltic material as thick as prac- ticable (at least 1 mil [25 μm]) and conform to all appropriate requirements for seal coat in ANSI/AWWA C1 04/A21.4. 10-9.4 Special coatings and linings. For special conditions, other types of coat- ings and linings may be available. Such special coatings and linings shall be specified in the invitation for bids and on the purchase order.ANSI AWWA C110 pdf download.
