ASC Engineered Solutions 310051800 – Frequently Asked Questions
1) On the ASC 1-1/2 x 1-1/2 x 2 black malleable iron tee, which opening is the 2 inch one?
It's a reducing tee with two 1-1/2 inch run ends and a 2 inch branch. All three openings are female pipe thread (FPT), so the 1-1/2 inch pipe runs straight through and the 2 inch tap comes off the side. If you need the larger size on the run instead, you want a different reducing configuration.
2) Will this black malleable iron tee thread onto standard black steel pipe?
Yes. All three ends are female NPT cut to ASME B1.20.1, the standard US pipe thread spec, so it mates with any threaded steel or iron pipe and nipples of the matching size. Use pipe dope or PTFE tape on the male threads as usual.
3) Is this ASC malleable iron tee UL Listed and FM Approved for fire sprinkler work?
Yes, the fitting carries UL/FM recognition, which is what an inspector looks for on threaded fittings in a wet or dry sprinkler system. It's a standard (STD) class black malleable iron fitting rated to ASME B16.3.
4) Can I use a black malleable iron tee on a domestic water line?
No. Black malleable iron is for gas, fire protection, air, and non-potable service. The black finish has no corrosion protection against water, so for potable water you want a galvanized malleable fitting or copper/CPVC. Use black where the drawing calls for black iron.
5) What pressure class is this 1-1/2 x 1-1/2 x 2 malleable iron tee?
Standard class (Class 150) per ASME B16.3, which sets both the pressure rating and the fitting dimensions. Because it's dimensioned to B16.3, the center-to-end takeouts match any other B16.3 Class 150 malleable tee, so it drops into a run laid out from standard fitting allowances.
6) What grade of malleable iron is this ASC tee made from?
The casting meets ASTM A197, the spec for cupola malleable iron used in threaded pipe fittings. That's the material callout a submittal for a gas or sprinkler job will ask for. The fitting weighs 1.86 lbs.
7) Do I need a bushing to land 2 inch pipe on this tee?
No bushing needed on the branch. The 2 inch outlet is already tapped full size at 2 inch FPT, so 2 inch threaded pipe or a 2 inch nipple goes straight in. Using a reducing tee rather than a full-size tee with a bushing keeps the takeout shorter and is usually what a sprinkler or gas inspector prefers.
8) How do I order the right ASC reducing tee, and what's the part number for this one?
ASC lists reducing tees by run x run x branch, so this one reads 1-1/2 x 1-1/2 x 2. The manufacturer part number is 310051800. If your branch and run sizes are reversed on the drawing, order the matching reversed callout instead, since the sizes are not interchangeable end to end.
