ASC Engineered Solutions 311525604 – Frequently Asked Questions
1) What size pipe does the ASC 2 x 2 x 1 galvanized malleable iron tee take on each opening?
Run openings are both 2 inch and the branch is 1 inch, so it's a reducing tee. All three ends are female pipe thread (FPT), threaded to ASME B1.20.1 NPT, so it screws onto male-threaded 2 inch pipe on the run and 1 inch pipe on the branch.
2) Is this ASC malleable iron tee approved for fire sprinkler piping?
It carries UL/FM approval, which is what an inspector looks for on sprinkler and fire protection piping. It is also extra heavy (XH) class malleable iron, pressure rated to ASME B16.3, which is the class typically specified for fire protection service over standard 150 class fittings.
3) What is the difference between an XH (extra heavy) malleable iron tee and a standard 150 class one?
XH is the 300 class malleable iron fitting: thicker wall, heavier body, higher working pressure than the standard 150 class fitting of the same size. Same NPT threads to ASME B1.20.1 and the same ASME B16.3 dimensional standard, so it threads onto the same pipe, it just handles more pressure and is what gets specified on fire protection and higher pressure service. If your drawing only calls for 150 class, a standard galvanized tee will fit the same pipe.
4) Can I use a galvanized malleable iron tee on steel pipe carrying water, or does it need to be black iron?
The galvanized coating is a hot dip zinc finish to ASTM A-153, which is what's used for wet service and damp or exposed locations where a black fitting would rust. Pair it with galvanized pipe, not black pipe, so you're not mixing coatings in the same run. Black malleable fittings are the ones used on gas and on dry systems.
5) Do I need a bushing to drop from 2 inch to 1 inch, or does this tee do it?
No bushing needed. The reduction is built into the fitting: 2 inch female thread on both run ends and 1 inch female thread on the branch. Thread 1 inch pipe or a 1 inch nipple straight into the branch. A bushing in a full-size 2 x 2 x 2 tee would work too, but it adds a joint and reduces the branch flow area more than a cast reducing tee does.
6) What material spec is this ASC tee made to, and does it matter for a submittal?
The body is malleable iron to ASTM A-197, which is the material callout most mechanical specs and submittals want to see on a threaded malleable fitting. Along with it you can cite ASME B16.3 for dimensions and pressure class, ASME B1.20.1 for the NPT threads, and ASTM A-153 for the galvanized coating.
7) What is the ASC part number for the 2 x 2 x 1 XH galvanized malleable tee?
The manufacturer part number is 311525604, from ASC Engineered Solutions. Order by that number to get the extra heavy galvanized malleable iron reducing tee rather than the 150 class version.
