[24: Table 10.1.1]
Steel piping shall not be used for general underground service unless specifically listed for such service. [24:10.1.2]
Where externally coated and wrapped and internally galvanized, steel pipe shall be permitted to be used between the check valve and the outside hose coupling for the fire department connection. [24:10.1.3]
The type and class of pipe for a particular underground installation shall be determined through consideration of the following factors:
- Fire resistance of the pipe
- Maximum system working pressure
- Depth at which the pipe is to be installed
- Soil conditions
- Corrosion
- Susceptibility of pipe to other external loads, including earth loads, installation beneath buildings, and traffic or vehicle loads
[24:10.1.4]
Piping, fittings, and other system components shall be rated for the maximum system working pressure to which they are exposed but shall not be rated at less than 150 psi (10 bar). [24:10.1.5]
[24:10.1.6]
Unless the requirements of 10.1.6.2 are met, all ferrous metal pipe shall be lined in accordance with the applicable standards in Table 10.1.1. [24:10.1.6.1]
Steel pipe utilized in fire department connections and protected in accordance with the requirements of 10.1.3 shall not be required to be internally lined. [24:10.1.6.2]
