From the 2021 UPC Illustrated Training Manual, Chapter 12, FUEL GAS PIPING
1208.6.7.1 Factory-Assembled Anodeless Risers. Factory-assembled anodeless risers shall be recommended by the manufacturer for the gas used and shall be leak tested by the manufacturer in accordance with written procedures. [NFPA 54:5.6.4.3(1)]
Anodeless risers are used to make the transition between underground PE pipe or tubing and metal pipe aboveground. As PE pipe must be installed below ground, risers are commonly used to connect the underground PE to aboveground piping materials. Anodeless risers are available as factory-assembled units and field-assembled kits. Anodeless risers are made from PE pipe inside a protective metal sheath, usually Schedule 40 steel pipe. The metal is protected from corrosion by a factory-applied coating and a separate anode is not required; hence the name “anodeless” (see Figure 1208.6.7.1). Factory-assembled risers usually have a 90-degree bend at the PE connection end and come in several lengths depending on the burial depth of the PE pipe.
1208.6.7.2 Service Head Adapters and Field-Assembled Anodeless Risers. Service head adapters and field-assembled anodeless risers incorporating service head adapters shall be recommended by the manufacturer for the gas used and shall be design-certified to meet the requirements of Category I of ASTM D2513 and 49 CFR 192.281(e). The manufacturer shall provide the user qualified installation instructions as prescribed by 49 CFR 192.283(b). [NFPA 54:5.6.4.3(2)]
The service head adapter is a transition riser, normally flexible, that will allow easy connection of the service meter or other transition needs. They will come with UV protective sheathing and a swivel head for connection to the metal piping (see Figure 1208.6.7.2).
