Description
150# Black Malleable Floor Flange
ASC Fig. 3190 Class 150 Floor Flange provides a threaded mounting flange for structural applications where pipe is secured to a floor, wall, platform, or other supporting surface.
Although commonly grouped with black malleable fittings, ASC specifies the Fig. 3190 Floor Flange as ductile iron manufactured to ASTM A536 Grade 65-45-12. The fitting features an NPT threaded center connection and a circular flange with mounting holes for securing the assembly to a compatible surface. ASC specifies this fitting for structural use only.

Construction Details
ASC identifies the Fig. 3190 Floor Flange as a ductile iron fitting manufactured from ASTM A536 Grade 65-45-12 material.
The floor flange combines a female threaded center connection with a broad circular mounting base. Bolt holes positioned around the flange allow the fitting to be mechanically secured to a compatible structural surface.
The manufacturer specifies NPT threads per ASME B1.20.1. This listing is for the black-finish configuration.
Important: ASC specifically identifies the Fig. 3190 fitting as being for structural use only.
Structural Mounting Design
Threaded Pipe Connection
The female NPT center connection accepts compatible male-threaded pipe, allowing the pipe to be mechanically attached to the floor flange.
Bolt-Hole Mounting
The circular flange includes mounting holes around the base so the fitting can be anchored to a compatible floor, wall, platform, framing member, or other structural surface.

Ductile Iron Construction
ASTM A536 Grade 65-45-12
ASC specifies ASTM A536 Grade 65-45-12 ductile iron for the Fig. 3190 Floor Flange. This is the manufacturer's specified material for the product even though floor flanges may be grouped commercially with malleable iron fittings.
Black Finish
This listing is for the black-finish floor flange. ASC's Fig. 3190 specification also recognizes a separate hot-dip galvanized finish configuration.
Threaded Center Connection
The center hub of the floor flange uses a female NPT connection for receiving compatible male-threaded pipe.
ASC specifies NPT threads conforming to ASME B1.20.1. Confirm the nominal pipe size and mating male thread before ordering.
Mounting Flange Geometry
Flange & Bolt Circle
ASC publishes both the overall flange diameter and bolt-circle diameter for each nominal size. These dimensions should be reviewed when matching the flange to an existing mounting pattern or planning a new installation.
Mounting Holes
The manufacturer also provides the mounting-hole diameter for each size, helping installers select compatible mounting hardware for the supporting surface and application.
Structural Applications
Pipe & Framework Support
- Pipe-based structural assemblies
- Rail and framework projects
- Equipment supports
- Display and fixture construction
- General structural mounting
Surface Mounting
- Floor mounting
- Wall mounting
- Platform mounting
- Structural attachment points
- Threaded pipe support assemblies
Installation & Selection Considerations
- Confirm the required nominal NPT pipe size before ordering.
- Review the published flange diameter, bolt circle, and bolt-hole diameter when planning the mounting pattern.
- Select mounting hardware appropriate for the supporting surface and structural load requirements.
- Ensure the mounting surface is suitable for the intended structural assembly and securely anchor the flange.
- Use the Fig. 3190 Floor Flange for structural applications only, as specified by ASC.
Use the ASC Fig. 3190 Floor Flange submittal to confirm ductile iron material, NPT thread requirements, nominal sizes, flange diameters, bolt-circle dimensions, mounting-hole diameters, and published weights before ordering.

Frequently Asked Questions
What is the ASC figure number for this floor flange?
ASC identifies this product as the Fig. 3190 Floor Flange.
Is the Fig. 3190 actually made from malleable iron?
ASC's product submittal specifically identifies the Fig. 3190 Floor Flange as ductile iron manufactured to ASTM A536 Grade 65-45-12.
What type of thread does the floor flange use?
The center connection uses NPT threads. ASC specifies NPT threads conforming to ASME B1.20.1.
What is this floor flange designed for?
ASC specifically identifies the Fig. 3190 fitting for structural use only.
What sizes are documented by ASC?
The supplied Fig. 3190 submittal documents nominal sizes of 1/2", 3/4", 1", 1-1/4", 1-1/2", and 2".
Does ASC provide mounting dimensions?
Yes. ASC provides the laying length, overall flange diameter, bolt-circle diameter, mounting-hole diameter, and approximate weight for each documented nominal size.
What finish is this listing for?
This listing is for the black-finish floor flange. ASC's Fig. 3190 specification recognizes black or hot-dip galvanized finishes.
Can I use this as a pressure-containing pipe flange?
