- ApplicationsUsageExampleDiagnosisDuctile iron pipe (DICL) pipe is used in water and waste water networks. Hydrostatic tests build up the pressure inside of pipes and check for leaks. The minimum pressure standards of DICL pipe depend upon the application.ASTM A795 / A795M - 21 Standard Specification for Black 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.
