ASC Engineered Solutions 310002209 – Frequently Asked Questions
1) Does the ASC 3 inch black malleable iron 90 degree elbow have female threads on both ends?
Both ends are FPT, so it takes male pipe thread on each side. Threads are cut to ASME B1.20.1 (NPT), which means it mates with standard 3 inch threaded black steel pipe nipples and threaded ends without an adapter. Size is 3 inch on both ends, so it's a straight 90, not a reducing ell.
2) Is this 3 inch malleable iron elbow approved for fire sprinkler piping?
It carries UL/FM approval, which is the listing fire protection contractors and AHJs look for on threaded fittings in sprinkler mains and branch lines. It's a Class 150 standard pattern fitting per ASME B16.3, black finish, so it's for dry systems and standard wet sprinkler service rather than potable water.
3) What is the difference between a standard and an extra heavy 3 inch malleable iron 90?
This one is standard pattern, which is the Class 150 fitting per ASME B16.3 and the normal choice for threaded black pipe in sprinkler, gas, and air service. Extra heavy (Class 300) is a thicker casting for higher working pressure. If the spec on your drawing calls out 300 lb, this standard fitting is not the right substitute.
4) What grade of iron is this ASC 3 inch elbow cast from?
The casting is malleable iron to ASTM A-197, the standard grade for cupola malleable iron pipe fittings. That's what gives it the ductility to take thread engagement and vibration without cracking the way gray cast iron would.
