ASC Engineered Solutions 311008403 – Frequently Asked Questions
1) Can I use this galvanized reducing elbow on a wet fire sprinkler line?
It's UL/FM recognized, which is what an inspector looks for on sprinkler piping. It's standard weight (STD class) malleable iron built to ASME B16.3 for both dimensions and pressure rating, hot-dip galvanized per ASTM A-153, which is the finish typically specified for wet-pipe systems where internal corrosion is a concern.
2) Will this elbow thread onto Schedule 40 steel pipe I already have on the job?
Yes, if the pipe is cut with standard NPT threads. The fitting's threads follow ASME B1.20.1 and its body dimensions follow ASME B16.3, the standard malleable iron threaded fitting dimensions, so it lays in at the same take-out as any other Class 150 standard malleable 90 of the same sizes.
3) Which end of the 1 x 3/4 reducing elbow is the 1 inch side?
It's a reducing 90, with a 1 inch female thread on one leg and a 3/4 inch female thread on the other. Order it as 1 x 3/4 and plumb it either direction, since the fitting itself doesn't care which side is supply. MPN is 311008403.
4) Is galvanized malleable iron the right fitting for a compressed air or steam line, or should I use black iron?
Malleable iron to ASTM A-197 in standard weight handles threaded steel pipe service generally. The galvanized coating is what decides it: use galvanized where moisture or corrosion is in play (water service, wet sprinkler, exterior, damp mechanical rooms). For dry gas, natural gas, and most steam work the trade standard is the same fitting in black iron, since the zinc offers no benefit there and some codes restrict galvanized on gas.
5) How much does a 1 x 3/4 galvanized malleable 90 weigh for hanger and takeoff calculations?
0.57 lbs each. Useful when you're totalling fitting weight on a hung run or figuring shipping on a bulk fitting order.
