tailieunhanh - Standard Specification for Black and Hot-Dipped Zinc-Coated (Galvanized) Welded and Seamless Steel Pipe for Fire Protection Use

This specification covers black and hot-dipped galvanized welded and seamless steel pipe in 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. | Designation A795 A795M 13 Standard Specification for Black and Hot-Dipped Zinc-Coated Galvanized Welded and Seamless Steel Pipe for Fire Protection Use1 This standard is issued under the fixed designation A795 A795M the number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision.
