Installation of Ductile-Iron Mains and Their Appurtenances
|Publication Date:||14 January 2017|
This standard describes installation procedures for ductile-iron mains and their appurtenances for potable water, wastewater, reclaimed water, and raw water.
Conditions not discussed. Installations that require special attention, techniques, and materials are not discussed. Each of these installations requires special considerations based on many influencing factors that cannot be discussed adequately in a single standard. These installations may require design by a competent engineer and consultation with representatives of the material manufacturing industry. Some of these special installations include the following:
1. Piping through rigid walls.
2. Piping on supports aboveground or belowground.
3. Piping requiring insulation.
4. Treatment plant or pump-station piping.
5. Flanged-joint piping.
6. Ball and socket piping.
7. Grooved and shouldered piping.
8. Restrained joint piping.
9. Industrial piping.
10. Piping through geologically hazardous areas.
11. Piping in high-density, stray-current environments.
12. Piping through unstable soil.
The purpose of this standard is to provide the minimum requirements for the installation of ductile-iron potable water, wastewater, reclaimed water, and raw water mains and their appurtenances, including materials, dimensions, tolerances, and testing procedures.
This standard can be referenced in purchase documents for installing ductileiron mains and their appurtenances. The stipulations of this standard apply when this document has been referenced and then only to the installation of ductile-iron mains and their appurtenances.
