ASC Engineered Solutions 311089007 – Frequently Asked Questions
1) Is the ASC Engineered Solutions 2 x 1-1/2 galvanized reducer threaded on both ends, and what thread standard does it use?
Both openings are female pipe thread (FPT), so it threads onto male-threaded pipe nipples or fitting ends on each side. Threads are cut to ASME B1.20.1, the standard NPT taper thread spec, so it mates with any standard NPT threaded steel or iron pipe. Use pipe dope or PTFE tape on the male threads as normal for a tapered thread joint.
2) What pipe sizes does this ASC malleable iron reducer connect, and which end is which?
It steps 2 inch down to 1-1/2 inch, both female threaded. Size 1 is the 2 inch end, Size 2 is the 1-1/2 inch end. It is a reducing coupling style fitting, so it joins a 2 inch threaded pipe end directly to a 1-1/2 inch threaded pipe end without a bushing.
3) Is this reducer UL listed and FM approved for fire sprinkler piping?
Yes. The 2 x 1-1/2 galvanized malleable iron reducer carries UL/FM recognition, which is what an inspector looks for on wet and dry sprinkler system piping. It is standard (STD) strength class, dimensioned and pressure rated to ASME B16.3.
4) Can I use a galvanized malleable iron reducer on a wet system or buried line where corrosion is a concern?
The galvanized finish is applied to ASTM A-153, the hot dip zinc coating spec for iron hardware, which is what gives it corrosion resistance in damp and wet service such as sprinkler mains and water lines. The body itself is malleable iron to ASTM A-197. For aggressive chemical service or where dissimilar metal corrosion is in play against copper or stainless, malleable iron is not the right choice.
5) Does this galvanized reducer meet spec for a mechanical drawing calling out ASME B16.3 Class 150 malleable iron fittings?
It is built to ASME B16.3 for both dimensions and pressure rating, in standard strength class, with ASME B1.20.1 threads and ASTM A-197 malleable iron. That is the combination normally called out on commercial plumbing and fire protection drawings for threaded malleable iron fittings. Submit the ASC part number 311089007 for the 2 x 1-1/2 galvanized reducer.
