SECTION 23.03 PART H. HIGH-DENSITY POLYETHYLENE (HDPE) PIPE, FITTINGS, SERVICES AND CONNECTORS High Density Polyethylene Water Main. All Polyethylene (PE) (HDPE High Density Polyethylene Pipe) water mains shall have a Ductile Iron pipe size (DIPS). Unless otherwise stated in the specifications or plans the HDPE water main shall have a pressure class rating of 200 psi for DR-11 PE4710 HDPE pipe as per ANSI/AWWA C906. DR9 shall be used for horizontal directional drilling. The construction and fabrication of the HDPE water main shall comply with the appropriate standards as set forth in the latest edition of ANSI/AWWA C906. 1) Provide Affidavit of Compliance of all HDPE as per ANSI/AWWA C906. 2) All HDPE pipe shall be color coded with a blue strip to indicate it is used for potable water. 3) Provide FM Fitting MJ adapter kit with stiffener for all connections to Cast Iron, PVC or Ductile Fittings and valves. 4) All fusion welds shall be in accordance with manufacturerÂ’s recommendations. All fusion welds shall be completed by properly trained personnel approved by the manufacturer. 5) Flanged and Mechanical Joint adapters to confirm to ASTM D3261. Markings for molded or machined flanged adapters of MJ adapters shall be per ASTM D3261. Fabricated (including machined) flange adapters shall be per ASTM F2206. 6) When new HDPE pipe is to be fused with existing HDPE piping, the purchaser of the new HDPE pipe shall inform the manufacturer of the cell classification of the existing HDPE pipe as per ASTM D3350, and obtain from the manufacturer a list of the validated fusion parameters that may be used to join the purchased piping to the existing piping. The manufacturers shall be consulted to determine the appropriate fusion procedures. 7) Polyethylene fusion fittings may be molded, thermoformed from pipe sections, or fabricated by heat fusion joining polyethylene components prepared from pipe, molded fittings, thermoformed pipe, or polyethylene sheet or block. 8) Butt Fusion Fittings shall be made of HDPE material with a minimum material designation code of PE4710 and with minimum cell classification of PE345464C. Butt Fusion Fittings shall meet the requirements of ASTM D3261. Molded and fabricated fittings shall have a pressure rating equal to the pipe unless otherwise specified on the plans. All fittings shall meet the requirements of ANSI/AWWA C906. Marking for molded fittings shall comply with the requirements of ASTM D3261. Fabricated fittings shall be marked in accordance with ASTM F2206. 9) Electrofusion Fittings shall be made of HDPE material with a minimum material designation code of PE4710. Electrofusion Fittings shall have a manufacturing standard of ASTM F1055. Markings shall be according to ASTM F1055. 3) All HDPE water main taps require an Electrofusion fitting, Transition Saddle (Corp Saddle). The Contractor shall provide the transition saddle and shall properly fasten the saddle to the main. Lincoln will provide the corporation stop as noted above. Electrofusion Transition Saddle shall have a manufacturing standard of ASTM F1055. The Contractor shall provide Electrofusion Transition Saddle equal to Georg Fischer Central Plastics Company with brass 360 alloy outlet materials, and stainless 304 compression ring, and CC Threads or approved equal.
