ASC Engineered Solutions 311090807 – Frequently Asked Questions
1) What size pipe does the ASC 3 x 2-1/2 galvanized malleable iron reducer connect?
It joins 3 inch pipe down to 2-1/2 inch pipe, with female pipe thread (FPT) on both ends. Both ends are tapped to ASME B1.20.1 NPT threads, so it mates with standard threaded steel or iron pipe of those two sizes. Part number 311090807.
2) Is this malleable iron reducer approved for fire sprinkler piping?
Yes, the 3 x 2-1/2 galvanized reducer is UL/FM rated, which is what a sprinkler contractor needs for wet and dry system piping. The galvanized coating is per ASTM A-153, the usual choice for dry systems where corrosion is a concern.
3) What pressure class is this 3 x 2-1/2 galvanized reducer, and can I use it on standard threaded pipe?
It is a standard (STD) class malleable iron fitting built to ASME B16.3, which is the dimensional and pressure-rating standard for threaded malleable iron fittings. Use it with standard weight threaded pipe on the same system.
4) Will a galvanized malleable iron reducer work on a steam or hot water line, or should I use something else?
The fitting is malleable iron to ASTM A-197 with NPT threads, made for threaded steel and iron piping systems. Galvanized coating is aimed at wet or corrosive service such as sprinkler and water lines. For steam, the zinc coating is generally avoided and black malleable iron in the same 3 x 2-1/2 size is the usual pick.
5) Do I need a bushing or a coupling instead of this reducer?
No, not for a 3 to 2-1/2 transition. This is a reducing coupling with female threads on both ends, so it takes male pipe thread on each side directly. A bushing would be male on the large end and thread into a fitting instead of onto pipe, and a straight coupling holds one size only.
6) How much does the 3 x 2-1/2 galvanized malleable iron reducer weigh?
3.4 lbs each. Worth knowing if you are hanging a run overhead and totaling fitting weight for support spacing, or estimating freight on a bulk order.
