scope:

This standard provides the field installation guidelines for buried steel water pipe, 4 in. (100 mm)* and larger.

The information contained in this standard is intended to be used as a guide to assist in the installation of steel water pipe.

Conditions that may require additional considerations. Installations that require special attention, techniques, and materials are not covered by this standard. Some of these installations are

1. Piping through rigid walls or structures.

2. Connections to appurtenances.

3. Piping on supports or on piles aboveground or belowground.

4. Piping subject to significant thermal stresses.

5. Treatment plant or pump-station piping.

6. Industrial piping.

7. Piping in seismic areas.

8. Piping in high-density, stray-current environments.

9. Piping through unstable soils or soils subject to sliding or soil drag.

10. Piping subject to excessive live loads.

11. Piping with cover less than 3 ft (900 mm).

12. Piping installed by horizontal directional drilling (HDD).

Purpose

The purpose of this standard is to provide the minimum requirements for the installation of buried steel water pipelines, including inspection, unloading, handling, storage, and testing.
