ASC Engineered Solutions 310081005 – Frequently Asked Questions
1) What thread does the 1-1/2 inch black malleable iron coupling take on each end?
Both ends are female pipe thread (FPT) in 1-1/2 inch, cut to ASME B1.20.1, which is standard NPT taper thread. So it joins two lengths of 1-1/2 inch threaded pipe straight through, same size on each side. Thread it with pipe dope or PTFE tape as you would any NPT joint.
2) Can this black malleable iron coupling be used on a fire sprinkler line?
It carries a UL/FM approval, which is what an AHJ looks for on fire protection piping. It is a standard weight (STD) malleable iron fitting to ASME B16.3, black finish. Confirm the pressure class on your drawing matches standard weight before you use it on a sprinkler main.
3) Is black malleable iron the right choice for a water line, or should I use galvanized?
Black malleable iron is the usual pick for gas, fire sprinkler, and closed-loop hydronic or steam service. It is not the choice for open potable water, where the bare iron will rust, galvanized or a copper/CPVC system is used there. This fitting is black, so spec it accordingly.
4) What standards does this ASC malleable iron coupling meet?
Three are on record: dimensions and pressure rating to ASME B16.3, material to ASTM A-197 (cupola malleable iron), and threads to ASME B1.20.1. That combination is what most mechanical specs call out for a Class 150 standard weight black fitting, so it should satisfy a submittal that names those documents.
5) Will this coupling thread onto pipe made by another manufacturer?
Yes. Because the threads are cut to ASME B1.20.1, it mates with any 1-1/2 inch NPT male pipe end regardless of who made the pipe or the nipple. Thread standard, not brand, governs the joint here.
