ASC Engineered Solutions 310046602 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions black malleable iron reducing tee take on each of its three openings?
It's a 1-1/2 x 1-1/4 x 1 inch reducing tee. The run takes 1-1/2 inch pipe on one end and 1-1/4 inch on the other, with a 1 inch branch outlet. All three openings are female pipe thread, so it threads directly onto male NPT pipe ends without any adapters.
2) Will this black malleable iron tee thread onto standard NPT pipe I already have on the job?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT pipe thread spec, so it mates with any standard threaded steel or iron pipe of the matching size. Use pipe dope or PTFE tape on the male ends as you would with any tapered thread joint.
3) Is this malleable iron tee UL Listed and FM Approved for fire sprinkler work?
It carries UL/FM recognition, so it can be used on fire protection piping where a listed and approved fitting is called for. It's a standard weight black malleable iron tee, which is the usual choice for wet sprinkler mains and branch lines. Always confirm the fitting matches what your approved sprinkler drawings specify.
4) Can I use a black malleable iron tee on a potable water line, or do I need galvanized?
Black malleable iron is for non-potable service. It's the standard fitting for black steel pipe on gas, fire sprinkler, and closed-loop hydronic heating systems. On potable water you want galvanized, brass, or copper instead, because black iron corrodes in open water service. Black also handles the compressed air and low pressure steam lines you find in mechanical rooms.
5) Will this reducing tee match the lay length of the fitting I'm pulling out?
It's built to ASME B16.3, the dimensional standard for threaded malleable iron fittings, so center-to-end dimensions are the same as any other B16.3 tee in the same 1-1/2 x 1-1/4 x 1 size combination regardless of who made it. A like-for-like swap won't change your pipe cut lengths.
6) What is the difference between a standard weight and an extra heavy malleable iron tee?
This one is standard weight (STD), which covers the large majority of threaded iron piping. Standard weight fittings are rated per ASME B16.3, the same standard that governs their dimensions, so a Class 150 standard fitting drops into any normal threaded run. Extra heavy (Class 300) fittings have thicker walls and a higher pressure rating, and you'd specify them only where the engineer calls for a 300 class system. If your drawing doesn't say Class 300, standard weight is what you want.
7) What grade of malleable iron is this tee made from?
The casting meets ASTM A197, the specification for cupola malleable iron used in threaded pipe fittings. That's the material grade behind the ductility malleable iron is bought for, it takes thread engagement and a wrench without the brittleness of gray cast iron.
8) How much does this 1-1/2 inch black iron tee weigh for a takeoff?
1.26 lbs each. Useful if you're figuring hanger spacing or freight on a large fitting count for a sprinkler or gas rough-in.
