ASC Engineered Solutions 310501200 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions 310501200 black malleable iron 90 elbow take?
It's a 1-1/4 inch elbow, same size on both ends, with female pipe thread (FPT) at each opening. Threads are cut to ASME B1.20.1, so it makes up with standard NPT male pipe thread or nipples in 1-1/4 inch.
2) What does XH mean on a malleable iron 90 elbow, and how is it different from standard?
XH is extra heavy (Class 300) malleable iron, a thicker wall and higher pressure rating than the common Class 150 standard fitting. Both are dimensioned to ASME B16.3, and the pressure rating for this elbow is per ASME B16.3 as well. If a drawing calls out Class 300 or extra heavy on a threaded iron line, this is the fitting to pull; a standard 150 elbow is not a substitute.
3) Is this 1-1/4 inch black elbow UL listed and FM approved for a fire sprinkler line?
Yes, the 310501200 elbow carries UL/FM approval, so it can be used on fire protection piping where the AHJ requires listed fittings. It's black malleable iron in extra heavy class, threaded both ends.
4) What material spec does this ASC 90 degree elbow meet?
The casting is malleable iron to ASTM A-197, with dimensions and pressure rating to ASME B16.3 and threads to ASME B1.20.1. That's the combination a mechanical spec normally calls out for threaded black iron fittings, so it drops straight into a submittal.
5) Will an extra heavy elbow line up the same as a standard 150 elbow when I lay out my piping?
Center-to-end dimensions for XH threaded malleable iron elbows follow ASME B16.3, which lists extra heavy separately from standard. They are not the same take-out, so if you are swapping a Class 150 elbow for this Class 300 one in an existing run, expect to re-cut the nipple rather than reuse it.
6) How much does the 1-1/4 inch XH black malleable iron 90 elbow weigh?
1.89 lbs each. Worth knowing when you're pricing freight on a bulk pull or figuring hanger loads on an overhead 1-1/4 inch run with several fittings in it.
