scope:

This standard describes 3-in. through 64-in. flanged ductile-iron pipe with ductile-iron or gray-iron threaded flanges for water supply service. Flanged pipe and flanges are rated for a maximum working pressure of 250 psi (1,720 kPa). However, 12-in. and smaller flanged joints with ductile-iron flanges may be rated for a maximum working pressure of 350 psi (2,413 kPa) as noted in the footnote of Table 1.

Purpose

The purpose of this standard is to provide users of the standard with the minimum requirements for flanged ductile-iron pipe with ductile-iron or gray-iron threaded flanges.

Application

This standard or sections of this standard can be referenced in specifications for purchasing and receiving flanged ductile-iron pipe. This standard can be used as a guide for casting, fabricating, and inspecting flanged ductile-iron pipe. The stipulations of this standard apply when this document has been referenced and then only to flanged
