ASC Engineered Solutions 310105408 – Frequently Asked Questions
1) What thread does the ASC G1190 1 inch floor flange take, and will it screw onto standard black pipe?
The G1190 floor flange is a 1 inch FPT (female pipe thread) fitting cut to ASME B1.20.1, which is standard NPT. It threads onto any 1 inch black steel or black iron pipe nipple with matching NPT male ends. Use pipe dope or PTFE tape on the male threads to seal.
2) Can I use this 1 inch black floor flange on a fire sprinkler system?
Yes. The G1190 is UL/FM rated, which is the listing fire protection contractors and AHJs look for on threaded fittings in sprinkler piping. It is a standard weight (STD) fitting rated per ASME B16.3.
3) Does this ASC floor flange meet ASME B16.3 for a spec job?
Both the dimensions and the pressure rating are to ASME B16.3, and the threads are to ASME B1.20.1. If the drawing calls for a Class 150 threaded black iron fitting dimensioned to B16.3, this 1 inch flange answers that callout. Material is ASTM A-197.
4) Is the ASC G1190 floor flange ductile iron or malleable iron, and does that matter for a pipe handrail or furniture build?
It is ductile iron, made to ASTM A-197, in a black finish. For pipe railing, shelving brackets, or industrial pipe furniture, that means a flange that takes bending and impact load at the base rather than a cast fitting that can crack. The black finish is unplated, so for outdoor or damp locations you will want to prime and paint it.
5) Both ends of this flange are listed as 1 inch FPT. What does that mean on a floor flange?
A floor flange has one threaded hub, and the G1190 carries it as 1 inch FPT on the fitting spec with matching 1 inch sizing on both size callouts. In practice you get one 1 inch female NPT socket to receive your pipe, and a drilled base plate that bolts or lags to the floor, wall, or ceiling. The mounting fasteners are not part of the fitting, so order lags or anchors to suit the substrate.
6) What is the ASC part number for the 1 inch black ductile iron floor flange?
The manufacturer part number is 310105408, sold under the ASC Engineered Solutions G1190 series as the 1 inch black ductile iron floor flange.
