ASC Engineered Solutions 310105606 – Frequently Asked Questions
1) What pipe size and thread does the ASC G1190 black floor flange take?
The G1190 floor flange is a 1-1/4 inch fitting with female pipe thread (FPT) on both ends, cut to ASME B1.20.1 NPT threads. So it threads straight onto standard 1-1/4 inch black iron or steel pipe with male NPT ends, no adapter needed.
2) Can I use a black iron floor flange like this one on a wet sprinkler line?
The G1190 is UL/FM listed, so it is acceptable where a listed fitting is required on fire protection piping. It is standard weight (STD) and rated per ASME B16.3. Black finish means no galvanizing, which is the normal choice for wet systems and closed-loop piping rather than exposed or corrosive service.
3) Is the ASC G1190 floor flange ductile iron or malleable iron?
It is ductile iron, made to ASTM A-197, with a black finish. That is a different material callout than a standard galvanized malleable fitting, so if a job spec calls out malleable iron specifically, check the submittal language before you order.
4) Will this floor flange match the dimensions on my piping drawing?
Dimensionally it is built to ASME B16.3, the standard for threaded iron fittings, so bolt circle, thickness and face-to-thread dimensions follow that standard rather than a proprietary pattern. Anything else on the run that is B16.3 class-150 threaded will line up the same way.
5) What is the part number for the 1-1/4 inch ASC G1190 floor flange?
Order it as ASC Engineered Solutions G1190, manufacturer part number 310105606, in the 1-1/4 inch black ductile iron configuration. That MPN is the full 1-1/4 inch item, not a size-independent series number.
6) How heavy is a 1-1/4 inch black floor flange, and can one person mount it overhead?
It weighs 0.9 lbs, so it is a one-hand piece on a ladder. The weight that matters on the install is the pipe it carries, not the flange, so size your anchors for the load and not the fitting.
