ASTM A795 Black and Hot-Dipped Zinc-Coated (Galvanized) Welded and Seamless Steel Pipe for Fire Protection Use

ASTM A795 covers black and hot-dipped galvanized welded and seamless steel pipe in sizes NPS 1/2 to NPS 10 inclusive, with wall thicknesses as given in Table 1 and Table 2. 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. Pipe ordered under this specification is intended 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.

This pipe is suitable for joining by the following methods:

1 Light-Weight Fire Protection Pipe— Rolled groove, welding, and fittings for plain end pipe. See Table 1 for dimensions.

2 Standard-Weight Fire Protection Pipe—Cut or rolled groove, threading, welding, and fittings for plain end pipe. See Table 2 for dimensions.

3 For pipe having dimensions other than those of Table 1 and Table 2, the joining method must be compatible with the pipe dimensions. A complete listing of standard light weight dimensions appears in ASME B36.10 and B36.19.
