ASC Engineered Solutions 310002803 – Frequently Asked Questions
1) What size and thread type are the openings on this 5 inch black malleable iron 90 degree elbow?
Both ends are 5 inch FPT, female pipe thread, so it threads onto male-threaded 5 inch pipe on each side. Threads are cut to ASME B1.20.1 (NPT), which is what standard black steel pipe nipples and field-cut pipe are threaded to.
2) Is this 5 inch malleable iron elbow approved for a fire sprinkler system?
It carries UL/FM approval, so it can be used in fire protection piping where UL Listed or FM Approved fittings are specified. The fitting is standard (STD) class malleable iron to ASME B16.3, with pressure ratings per that same standard.
3) Can I use a black malleable iron elbow on a potable water line?
No. Black malleable iron fittings are for gas, fire protection, compressed air, and low pressure steam or process piping, not potable water, because the black finish has no corrosion protection and will rust in wet service. For water you want galvanized malleable iron, copper, or CPVC. The black finish here is what makes it a gas and dry-system fitting.
4) Is a threaded 5 inch elbow the right choice, or should I be using grooved or welded fittings at that size?
At 5 inch, threaded malleable iron is at the large end of practical. It works, and it is the right call when you are tying into existing threaded pipe or cannot weld or roll grooves on site. But 5 inch threaded joints are heavy to handle (the fitting alone is 13.9 lbs before pipe), take a large power threader, and need real torque to make up. If you are running new 5 inch line in a mechanical room, grooved couplings or welded fittings are faster and easier to support. Use this where the existing system is already FPT.
5) Will this elbow meet a spec calling for ASTM A197 malleable iron fittings?
Yes, the material is furnished to ASTM A-197, which is the cupola malleable iron specification normally cited for threaded malleable fittings. Dimensions and pressure class follow ASME B16.3 and threads follow ASME B1.20.1, so it answers the three lines a mechanical spec usually lists for a black malleable elbow.
6) Is this elbow a straight 5 inch by 5 inch, or a reducing elbow?
Straight. Both ends are 5 inch, so it turns 90 degrees without changing pipe size. If you need to drop to a smaller line through the turn, you want a reducing elbow or this elbow plus a bushing or reducer.
7) Do I need to worry about supporting the weight of a 5 inch black iron elbow overhead?
Yes. The fitting by itself is 13.9 lbs, and once you add 5 inch pipe on both legs the load at a change of direction gets significant fast. Plan hangers close to the elbow on both sides rather than letting the pipe carry the fitting between distant supports.
