ASTM A795 Pipe

ASTM A795 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 zinc-coated (galvanized) welded and seamless steel pipe for fire protection use. 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. The steel shall conform to the required chemical composition. Each length of pipe shall be subjected to a hydrostatic test without leakage through the pipe wall. As an alternative to the hydrostatic test, and when accepted by the purchaser, each pipe shall be tested with a non-destructive electrical method. Finally, flattening test shall be performed on the pipe in accordance with, electric-resistance-welded pipe, and furnace-welded pipe.

ASTM A795 pipe diameter is in NPS 1/2 to NPS 10.
