ASC Engineered Solutions 310031208 – Frequently Asked Questions
1) Are all three openings on the ASC 3 inch black malleable iron tee the same size?
Yes, it's a straight 3 inch tee. All three outlets are 3 inch with female pipe thread (FPT) on every branch, so run and branch are equal. If you need to step the branch down, you'd want a reducing tee or a 3 inch bushing in the branch outlet.
2) Is this black iron tee acceptable for a fire sprinkler line?
It carries UL/FM approval, so it's suitable for use in listed fire protection piping. The black finish and malleable iron body are the usual combination for sprinkler mains and branch lines. Confirm the pressure class against your hydraulic calculation before you spec it into the system.
3) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron is uncoated and will rust in a wet potable system, and there's no lead-free potable certification on this fitting. Black iron is for gas, compressed air, fire sprinkler, and similar dry or closed-loop service. For potable water, use galvanized malleable iron, copper, or brass.
4) What is the difference between standard and extra heavy malleable iron fittings, and which is this one?
This is a STD (standard class) fitting. Extra heavy (XH, class 300) fittings have thicker walls and a higher pressure rating for the same nominal size. For ordinary black iron gas, air, or sprinkler work at standard working pressures, standard class is what gets specified; go to extra heavy only when the drawing calls for class 300.
5) What specs does this ASC 3 inch tee meet for a submittal?
Three things to put on the submittal: the body is malleable iron to ASTM A-197, dimensions and pressure rating follow ASME B16.3, and threads follow ASME B1.20.1 (NPT). It's also UL/FM approved. Manufacturer part number is 310031208.
6) Do I need pipe dope or tape on these NPT threads?
Yes. NPT is a tapered thread and seals on thread engagement, not a gasket, so a thread sealant is required on all three joints. Use a sealant rated for the service, gas-rated dope for fuel gas lines. The fitting ships bare iron with no sealant applied.
