Pipe ordered under this specification is ashm for use in fire protection systems. The pipe may be bent, but it is not intended for bending made at ambient temperature wherein the inside diameter of the bend is less than twelve times the outside diameter of the pipe being bent Note 2. Note 2 — Successful bending of pipe is a function of equipment and technique as well as pipe properties.


This abstract is a brief summary of the referenced standard. Pipe having other wall thicknesses may be furnished provided such pipe complies with all other requirements of this specification and the outside diameter is as given in Table 2.

Combining values from the two systems may result in non-conformance with the standard. Within the text, the SI units are shown in brackets.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This specification covers black and hot-dipped zinc-coated galvanized welded and seamless steel pipe for fire protection use.
