ASC Engineered Solutions 310031802 – Frequently Asked Questions
1) Is the 5 inch black malleable iron tee threaded on all three openings?
All three outlets are FPT (female pipe thread), 5 inch on every branch, so it's a straight run-and-branch tee with no reducing. Threads follow ASME B1.20.1, the NPT standard, so it mates with any standard 5 inch NPT male pipe nipple or fitting.
2) Can I use this black malleable iron tee on a fire sprinkler system?
It's UL/FM rated, which is what an AHJ looks for on threaded fittings in a wet or dry sprinkler line. Black malleable iron with standard (STD) pressure class per ASME B16.3 is the usual choice for sprinkler and black steel pipe work. For potable water, use a different material.
3) Will this 5 inch tee match the laying length of the fitting I'm replacing?
Its dimensions are built to ASME B16.3, the standard for threaded malleable iron fittings. Any other 5 inch Class 150 standard-pattern malleable tee made to B16.3 has the same center-to-end dimensions, so it drops into the same spot on the line without re-cutting pipe.
4) What's the difference between a black and a galvanized malleable iron tee?
The finish. This one is black, meaning uncoated malleable iron, used on gas, sprinkler, steam, and other non-corrosive dry or closed-loop service. Galvanized is the zinc-coated version for wet or exposed lines where rust would be a problem. Dimensionally both follow ASME B16.3, so they interchange on the pipe.
5) How heavy is a 5 inch malleable iron tee, and do I need to support it?
It weighs 19.42 lbs bare, before pipe. At that weight a 5 inch tee is a two-hand lift on a ladder and it wants hangers close to the fitting rather than letting the branch cantilever off the run.
6) Does this tee need a gasket or sealant, or does it seal on the thread?
It seals on the taper. FPT ends to ASME B1.20.1 are tapered NPT, so the joint is made with pipe dope or PTFE tape on the male thread and wrenched up. No gasket, no O-ring, nothing else supplied with the fitting.
7) Is this tee strong enough for a high pressure line, or do I need extra heavy?
This is the standard (STD) pattern, rated per ASME B16.3, which is the Class 150 malleable fitting. If your drawing calls for Class 300 extra heavy, this is not the fitting; you need the extra heavy pattern instead.
8) What material spec is this malleable iron tee made to?
Castings are made to ASTM A-197, the spec for cupola malleable iron used in threaded pipe fittings. That's the material call-out most mechanical and fire protection submittals ask for on black malleable fittings.
9) What part number do I order for the ASC 5 inch black malleable tee?
ASC Engineered Solutions part number 310031802, a 5 x 5 x 5 black malleable iron tee, all female threaded.
