ASC Engineered Solutions 311001606 – Frequently Asked Questions
1) Is this 1-1/2 inch malleable iron elbow approved for fire sprinkler piping?
It carries UL/FM approval, which is the listing sprinkler contractors and AHJs look for on threaded fire protection fittings. It is standard weight (STD) malleable iron to ASTM A-197 with pressure ratings per ASME B16.3.
2) Can a galvanized malleable iron 90 elbow be used on an outdoor or wet system line?
The galvanized coating is applied to ASTM A-153, the hot-dip spec for hardware, which is what you want for corrosion protection on exterior runs, dry and pre-action sprinkler piping, and damp mechanical rooms. Pair it with galvanized pipe and nipples so you are not mixing black and galvanized in the same run.
3) Will this elbow match the dimensions of the galvanized fittings already on my job?
Center-to-end dimensions follow ASME B16.3, the same standard other malleable iron threaded fittings are built to, so it drops into an existing galvanized run without changing your takeouts. Fitting weight is 1.34 lbs.
4) Is standard weight malleable iron enough, or do I need an extra heavy 150 fitting?
This one is standard weight (STD) malleable iron, the class used for most threaded water, air, gas and sprinkler branch work at ASME B16.3 pressure ratings. If your spec or engineer calls out extra heavy for higher working pressure, standard weight will not satisfy it and you need the heavier class instead.
5) What is the ASC Engineered Solutions part number for the 1-1/2 inch galvanized 90 degree elbow?
Order it as part number 311001606. It is a 1-1/2 x 1-1/2 inch straight 90 degree elbow, galvanized malleable iron, not a reducing elbow.
6) Do I need pipe dope or tape with this threaded elbow, or does it come sealed?
It ships as a bare fitting. NPT taper threads per ASME B1.20.1 seal on the thread engagement, so you still apply thread sealant or PTFE tape appropriate to the service before making it up. No gaskets or sealing rings are supplied.
