02475.00 1104 Section 02475 - Potable Water Fitting Materials
Description
02475.00Scope - This Section includes the requirements for fittings, restrained joints, and couplings
for ductile iron pipe, high density polyethylene (HDPE) pipe , and polyvinyl chloride (PVC) pipe for potable water systems.
Materials
02475.10General - Bolts, nuts and washers used for securing fittings shall be of similar Materials
Steel bolts shall meet the requirements of ASTM A307 for carbon steel, or ASTM F593 for stainless steel. Nuts shall meet the requirements of ASTM A563 for carbon steel and ASTM F594 for stainless steel. Iron bolts and nuts shall meet the requirements of ASTM A536, grade 65- 45-12. Galvanize carbon steel bolts, nuts and washers according to 02560.40.
All Materials in contact with potable water shall con form to ANSI/NSF Standard 61, Drinking Water System Components - Health Effects or equivalent , and ANSI/NSF Standard 372, Drinking Water System Components - Lead Content .
02475.20Ductile Iron Pipe Fittings - Fittings for ductile iron pipe shall meet the requirements of
AWWA C110 or AWWA C153, and shall have a minimum working pressure rating of 250 psi. Joints shall meet the requirements of AWWA C111. Fittings shall be cement mortar lined and seal coated, meeting the requirements of AWWA C104. Provide gaskets for ductile iron flanged joints that are composed of synthetic rubber, full faced, 1/8-inch thick, and conform to ANSI/AWWA C111/A21.1. Ring gaskets will be permitted only where specified or shown. The type, material and identification mark for bolts and nuts shall be provided.
02475.31High Density Polyethylene (HDPE) Pipe Fittings - Use HDPE pipe fittings meeting the
requirements of ANSI/AWWA C906, Standard Code Designation of PE3408. Furnish all pipe fittings with a minimum dimension ratio (DR) of 17. Join pipe and fittings using a thermal butt fusion method that meets the requirements of ASTM D3261. Fittings shall be of the same class as the HDPE pipe.
02475.40Fittings for Polyvinyl Chloride Pipe 4 Inches and Larger - Fittings for PV C pipe 4 inches
in diameter and larger shall be the same as specified for ductile iron pipe.
02475.45Fittings for Polyvinyl Chloride Pipe Under 4 Inches - Fittings for PVC pipe under
4 inches in diameter shall meet the requirements of ASTM D2466.
02475.50Restrained Joints - Restrain pipe, fittings, and valves by using an approved bolted or
boltless system. Design the restraint system to operate at a working pressure that is greater than the hydrostatic test pressure identified in 01140.51(a) , unless otherwise shown. No device utilizing round point set screws will be allowed. Restraint systems provided for pipe bells shall be certified for use by the pipe manufacturer.
02475.60Bolted, Sleeve-Type Couplings for Plain -End Pipe - Bolted, sleeve ty pe couplings,
reducing or transition couplings, and flanged coupling adapters used to join plain end pipe shall meet the requirements of AWWA C219. Buried couplings used for connecting ductile iron, gray cast iron , or PVC pipe shall be ductile iron.
