ASC Engineered Solutions 311055602 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions 3 x 2-1/2 x 2-1/2 galvanized malleable iron tee take on each opening?
Two 3 inch run openings feed a 2-1/2 inch... not quite. Read it in order: the run is 3 inch, and the second and third openings are 2-1/2 inch. All three are female pipe thread (FPT), so it threads onto male-threaded pipe nipples at every port. Threads are cut to ASME B1.20.1 NPT.
2) Can I use this 3 x 2-1/2 x 2-1/2 galvanized tee on a fire sprinkler line?
Yes. The ASC Engineered Solutions 3 x 2-1/2 x 2-1/2 galvanized malleable iron tee is UL/FM recognized, which is what an AHJ looks for on a threaded sprinkler main or branch. It is standard (STD) strength malleable iron with NPT threads to ASME B1.20.1.
3) Do I need a reducing bushing to drop from 3 inch to 2-1/2 inch pipe with this tee?
No bushing needed. This is a reducing tee: the 3 inch port and the two 2-1/2 inch ports are cast into the one fitting, so you thread 3 inch pipe into one end and 2-1/2 inch into the others. Fewer joints than a straight tee plus bushings, and less pressure drop on the branch.
4) Will this tee meet a spec calling out ASME B16.3 fittings?
It will. The 3 x 2-1/2 x 2-1/2 galvanized malleable iron tee is built to ASME B16.3 for both dimensions and pressure rating, at standard (STD) class. Submittal-wise that pairs with ASTM A-197 malleable iron, ASTM A-153 hot dip galvanizing, and ASME B1.20.1 NPT threads.
5) Is a galvanized malleable iron tee the right choice for a wet system, or should I use black iron?
Galvanized is the call where the fitting sees water or damp conditions: the hot dip coating here meets ASTM A-153, which is what protects the threads and body from corrosion on wet sprinkler lines and outdoor or exposed runs. Black malleable iron is the usual pick on dry gas service and dry-pipe interiors where the zinc coating buys you nothing. The body castings are ASTM A-197 malleable iron either way.
6) Can I thread copper or PVC into this fitting?
Only through a transition. All three openings are female NPT (FPT) to ASME B1.20.1, so anything with matching male NPT threads will mate, including a male adapter off copper or a threaded PVC male adapter. Do not attempt to sweat or solvent weld to it, it is a threaded malleable iron fitting.
