ASC Engineered Solutions 310009808 – Frequently Asked Questions
1) Is the ASC 1-1/2 x 1 inch black malleable iron 90 elbow a reducing elbow, and which end is which size?
It's a reducing 90 degree elbow: one end takes 1-1/2 inch pipe, the other takes 1 inch. Both ends are female pipe thread (FPT), so it threads onto male-threaded pipe ends on both sides. Use it where a 1-1/2 inch run turns and steps down to 1 inch in the same fitting, instead of running an elbow plus a separate bushing.
2) Will this black iron elbow thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, which is the standard American pipe thread spec (NPT), so it makes up with ordinary threaded black steel pipe and nipples using pipe dope or PTFE tape. Fitting dimensions follow ASME B16.3, the standard for malleable iron threaded fittings, so laying length and thread engagement match other B16.3 fittings on the run.
3) Can I use this malleable iron elbow on a fire sprinkler line?
It carries a UL/FM listing, so it's acceptable for fire protection piping where the authority having jurisdiction requires listed fittings. It's standard weight (STD) malleable iron with pressure ratings per ASME B16.3. For sprinkler work confirm the system pressure against the B16.3 rating for the class and size you're installing.
4) Does STD strength mean this is a Class 150 fitting?
The fitting is designated standard weight (STD) rather than extra heavy, and its pressure rating follows ASME B16.3. Standard weight is the common choice for general black iron gas, air, and sprinkler work; if your spec calls for extra heavy on a higher pressure system, a STD fitting is not a substitute.
5) What grade of malleable iron is this elbow made from?
The casting is made to ASTM A-197, the specification for cupola malleable iron used in threaded pipe fittings. That's the material grade behind the ASME B16.3 pressure ratings, and it's what lets the fitting take thread engagement and wrench torque without cracking the way a cast gray iron fitting can.
6) What is the ASC part number for this 1-1/2 x 1 reducing black iron elbow?
ASC Engineered Solutions part number 310009808. Order by that MPN if you're matching fittings already on the job or setting up a standing MRO order for black iron reducing ells.
