ASC Engineered Solutions 310105804 – Frequently Asked Questions
1) What thread does the ASC G1190 1-1/2 inch floor flange take, and will it screw onto standard black pipe?
The G1190 floor flange has a 1-1/2 inch female pipe thread (FPT) hub cut to ASME B1.20.1, the standard NPT thread spec. So it threads directly onto any 1-1/2 inch male-threaded black steel or black iron pipe nipple without an adapter. Nothing on the flange is welded or slip-fit; it is a screwed connection.
2) Is the ASC G1190 floor flange UL listed and FM approved for a sprinkler or fire protection job?
Yes, the G1190 carries UL/FM recognition, so it can be specified on fire protection piping where the submittal calls for UL Listed and FM Approved fittings. It is rated as standard (STD) strength with pressure ratings per ASME B16.3.
3) Is this ASC floor flange ductile iron or malleable iron, and does that matter for a pipe railing or table base?
It is ductile iron, made to ASTM A-197, with a black finish. For a handrail post base, furniture leg, or pipe-frame table, that means a cast iron fitting with better impact and bending toughness than a plain gray iron casting, and the black finish is a mill coating rather than a decorative or corrosion-resistant plating. Outdoors or in a wet area it will want paint or clear coat.
4) What pressure class is this 1-1/2 inch black floor flange, and can I use it on a pressurized line?
The G1190 is a standard (STD) class fitting dimensioned and pressure rated to ASME B16.3, which is the threaded fittings standard used for Class 150 and Class 300 iron fittings. Use it where the drawing calls for a standard class threaded iron fitting; if the spec calls for extra heavy, this is not that fitting.
5) Do I get mounting screws with the ASC G1190 floor flange?
No fasteners come with it. The G1190 is the flange casting only, a 1.2 lb ductile iron part with bolt holes cast in; you supply the lag screws, machine screws, or anchors to suit whatever you are mounting to. Order those separately with the job.
6) Will the ASC G1190 flange match other threaded black iron fittings already on my run?
Yes, as long as the existing run is 1-1/2 inch threaded pipe. Both the threads (ASME B1.20.1) and the face-to-end dimensions (ASME B16.3) are made to the same standards the rest of the black threaded fitting line is built to, so it interchanges with other 1-1/2 inch standard class threaded iron fittings on the same pipe. Finish is black, so it visually matches black pipe and fittings.
7) Is a threaded floor flange like this the right choice, or do I need a bolted companion flange?
A floor flange like the G1190 is a threaded base plate: it screws onto the end of a pipe and bolts flat to a floor, wall, or ceiling to anchor the pipe. It is not a pipe-to-pipe joint. If you need to bolt two pipe ends together with a gasket between them, that is a companion or bolted flange pair, not this part. Use the G1190 when the pipe terminates and needs a mounting foot.
8) What part number do I order for the ASC 1-1/2 inch black ductile iron floor flange?
The manufacturer part number is 310105804, sold as the G1190 series 1-1/2 inch black ductile iron floor flange from ASC Engineered Solutions. There is one configuration, so size and finish are fixed at 1-1/2 inch and black.
