ASC Engineered Solutions 310042205 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 310042205 black malleable iron tee?
It's a reducing tee with two 1/2 inch ports and one 1 inch port. All three openings are female pipe thread (FPT), so it threads onto male pipe ends or nipples. The common use is branching a 1/2 inch run off a 1 inch line, or stepping a 1/2 inch run up to a 1 inch takeoff.
2) Is this black malleable iron tee approved for fire sprinkler piping?
The ASC Engineered Solutions 310042205 tee carries UL/FM approval, which is what a sprinkler contractor needs for fittings in a listed fire protection system. It's standard (STD) strength black malleable iron to ASTM A-197, with dimensions and pressure rating per ASME B16.3.
3) Will this tee thread onto standard NPT black pipe?
Yes. The threads are cut to ASME B1.20.1, which is the NPT standard, so it mates with any standard black steel pipe or nipple of the matching size. Use pipe dope or PTFE tape on the male threads; the seal is on the taper, not on a gasket.
4) Can I use a black malleable iron tee on a water line, or should it be galvanized?
Black malleable iron is the fitting used on gas, fire sprinkler, steam, and closed-loop hydronic systems. For potable or open water service where the pipe will see fresh oxygenated water, galvanized is the usual call, since black iron rusts in that duty. This fitting is black finish malleable iron.
5) What does STD strength mean on a malleable iron fitting, and is it strong enough for gas piping?
STD is the standard class rating (as opposed to extra heavy), pressure rated per ASME B16.3. That's the class normally specified for black iron gas distribution and sprinkler branch piping in commercial buildings. If your drawing calls for a 300 class or extra heavy fitting, this is not the one.
6) Which opening is the 1 inch one on a 1/2 x 1/2 x 1 tee?
On a reducing tee written 1/2 x 1/2 x 1, the first two figures are the run (both 1/2 inch) and the last is the branch, so the 1 inch port is the branch outlet coming off the side. The 1/2 inch openings are in line with each other.
7) How much does this 1/2 x 1/2 x 1 malleable iron tee weigh?
About 0.55 lbs each. Worth knowing if you're pricing freight on a bulk order or figuring hanger spacing on a run with a lot of fittings in it.
