ASC Engineered Solutions 310081401 – Frequently Asked Questions
1) Will a 2-1/2 inch black malleable iron coupling thread onto standard black steel pipe?
Yes. The ASC Engineered Solutions 2-1/2 inch black malleable iron coupling has FPT (female pipe thread) on both ends, cut to ASME B1.20.1, which is the standard NPT thread used on black steel and galvanized steel pipe. Both ends are the same size, 2-1/2 inch, so it joins two male-threaded pipe ends of the same nominal size.
2) Is this 2-1/2 inch malleable iron coupling acceptable for a fire sprinkler line?
It carries a UL/FM listing, which is the approval fire protection inspectors look for on threaded fittings in sprinkler piping. It is a standard (STD) class black malleable iron fitting with pressure rating per ASME B16.3. Confirm the working pressure your sprinkler drawing calls for matches the STD class rating before you commit it to the job.
3) Does this ASC coupling meet a submittal calling out ASTM A197 malleable iron fittings?
Yes. The material is manufactured to ASTM A-197, with dimensions and pressure rating to ASME B16.3 and threads to ASME B1.20.1. Those are the three callouts that usually appear together on a mechanical submittal for threaded malleable iron, and it is UL/FM listed as well. Order it by ASC part number 310081401.
