2 inch Black Iron Floor Flange

2" Black Malleable Iron Floor Flange – For Fixed Pipe Mounting and System Support

The 2" Black Malleable Iron Floor Flange is a threaded fitting used to anchor piping systems to structural surfaces such as floors, walls, or ceilings. Manufactured from cast malleable iron and finished with a black oxide coating, this flange is engineered to provide mechanical stability and alignment in both new installations and retrofit configurations.

Designed to accommodate standard National Pipe Thread (NPT) pipe connections, the flange offers consistent thread engagement and distributes mechanical loads across four or more mounting holes. It is suitable for non-pressurized gas, steam, or air systems, as well as select low-pressure water applications where black iron is permitted by code.

Performance Features

• ✅ NPT Compatibility – Precision-tapped threads support proper fitment with male-threaded steel pipe, aiding in leak prevention and axial stability.
• ✅ Malleable Iron Construction – Offers excellent tensile strength and fracture resistance, especially in installations subject to vibration or minor mechanical impact.
• ✅ Mounting Flexibility – Four-bolt configuration allows secure attachment to a variety of substrates, including wood, concrete, or steel framing.
• ✅ Corrosion Resistance – Black oxide finish provides moderate protection against rust in indoor dry environments.
• ✅ Dimensional Consistency – Manufactured to industry-standard tolerances for reliable repeatable fitment.

Technical Specifications

• Material: Black malleable iron (ASTM A197/A47)
• Nominal Size: 2-inch
• Connection: Female NPT
• Mounting: Four-hole flange face, countersunk
• Temperature Range: Suitable for ambient and elevated temperatures in accordance with system design

Common Applications

Utilized in mechanical systems to stabilize vertical or horizontal pipe runs, this floor flange is typical in heating loops, compressed air lines, exposed gas piping, and structural pipe assemblies. It is frequently used where piping must be anchored to reduce movement or isolate vibration.

Material Note

Malleable iron is favored in industrial and commercial piping systems for its machinability, mechanical strength, and resistance to deformation under load. Unlike ductile iron, it offers higher elasticity in light-duty structural applications.

The 2" Black Malleable Iron Floor Flange is a reliable hardware component for mechanical installations requiring fixed positioning and stable pipe termination. Always verify local code requirements for black iron usage in potable water or gas lines before installation.
