ASC Engineered Solutions 310505003 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions 310505003 black malleable iron 90 degree elbow connect?
It is a reducing elbow: 1-1/4 inch on one end, 1 inch on the other. Both ends are female pipe thread (FPT), so it threads onto male-threaded pipe nipples or cut-and-threaded pipe. Use it where a 1-1/4 inch run has to turn and step down to 1 inch in a single fitting instead of an elbow plus a separate bushing.
2) Is the 1-1/4 x 1 inch XH black malleable elbow approved for fire sprinkler piping?
It carries UL/FM approval, which is what an AHJ looks for on fire protection piping. It is an extra heavy (XH) Class 300 style malleable fitting to ASME B16.3, black finish, so it suits fire sprinkler mains and branch lines where black steel pipe is used. Confirm the approval covers your specific system pressure with the engineer of record.
3) Can I use a black malleable iron elbow on a potable water line?
No. Black malleable iron is for gas, steam, compressed air, fire protection, and other non-potable service. It has no corrosion-resistant coating and will rust in water service. For potable water on threaded pipe, use galvanized malleable or a brass or stainless fitting instead.
4) What is the difference between a standard and an XH (extra heavy) malleable iron 90 elbow?
XH means extra heavy: thicker walls and a higher pressure class than the standard weight version of the same size. Pick XH when the spec calls for Class 300 malleable, on higher pressure steam, compressed air, or fire protection work. If the drawing only calls for Class 150 standard weight, the lighter fitting is the cheaper and correct choice. This one is XH and rated per ASME B16.3.
5) What material spec does this ASC malleable iron fitting meet?
The casting is made to ASTM A-197, the standard for cupola malleable iron fittings, with dimensions to ASME B16.3. Those two together are what most mechanical specs cite for threaded malleable iron elbows, so it drops straight into a job specified that way.
6) How much does the 1-1/4 x 1 inch extra heavy black malleable 90 elbow weigh?
About 1.6 lbs each. Worth knowing if you are estimating hanger spacing and total load on a threaded run, or pricing freight on a full pallet of fittings for a rough-in.
7) Do I order the ASC reducing elbow by orientation, or is 1-1/4 x 1 the same either way?
There is no handing on a reducing elbow. One socket is 1-1/4 inch FPT and the other is 1 inch FPT, and you simply orient it in the run as needed. Order by model 310505003 for this size combination.
