ASC Engineered Solutions 310521406 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions 1 x 1 x 1/2 black malleable iron tee accept on each opening?
Two runs at 1 inch and a reducing branch at 1/2 inch. All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe nipples or male adapters. Threads are cut to ASME B1.20.1, the standard NPT taper thread spec, so it mates with any standard NPT male pipe end of the matching size.
2) Is this malleable iron tee rated for a fire sprinkler line?
It carries a UL/FM rating, which is what an AHJ looks for on fire protection piping. It is an extra heavy (XH) black malleable iron fitting built to ASME B16.3 for both dimensions and pressure rating.
3) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron is for gas, fire protection, steam, and compressed air service, not potable water, because the uncoated black finish corrodes in wet potable service. For water you want galvanized malleable iron, copper, or CPVC instead. This fitting is supplied in the black finish.
4) What is the difference between an XH (extra heavy) malleable tee and a standard class 150 one?
XH is the heavier wall, higher pressure class of malleable iron fitting; standard weight is the lighter class 150. Both are dimensioned under ASME B16.3, but the extra heavy body is what you order when the system pressure or the mechanical loading on the branch is higher than a standard fitting is rated for. If your drawing calls out class 300 or extra heavy black malleable, this 1 x 1 x 1/2 tee is the right class.
5) What material spec does this ASC tee meet, and does it matter for a submittal?
The casting is malleable iron to ASTM A-197, with dimensions and pressure rating to ASME B16.3 and threads to ASME B1.20.1. Those three callouts are what most mechanical specs and submittal packages ask for on threaded black iron fittings, so you can list them directly.
