Flange Configuration
Female NPT Connection
The center opening is internally threaded to accept compatible male NPT pipe without requiring a welded connection.
Raised Face
The raised sealing surface concentrates gasket compression around the pipe opening for dependable flange sealing.
Class 150 Bolt Pattern
Pre-drilled bolt holes provide compatibility with corresponding Class 150 mating flanges and bolting arrangements.
Construction Details
The flange is manufactured from durable ductile iron for dependable mechanical strength and long service life in compatible piping systems.
Precision-machined female NPT threads provide a secure threaded connection to pipe while eliminating the need for field welding.
The galvanized finish helps protect the ductile iron surface against rust and environmental corrosion during indoor or outdoor service.
Why Choose a Threaded Flange?
No Welding Required
- Connects directly to threaded pipe
- Useful where welding is impractical
- Simplifies field installation
- Allows easier replacement or modification
- Reduces hot-work requirements
Flanged System Compatibility
- Standard Class 150 bolt pattern
- Raised face sealing surface
- Compatible with suitable mating flanges
- Allows gasketed bolted assembly
- Useful for valves and equipment connections
Galvanized Finish
Corrosion Protection
The galvanized coating provides added protection against rust and environmental exposure in compatible applications.
Indoor & Outdoor Use
The protective finish makes the flange suitable for a wide range of mechanical, agricultural, commercial, and water service installations.
Raised Face Design
Focused Gasket Compression
The raised face concentrates gasket loading around the sealing area to help create a dependable flange joint.
Mating Flange Compatibility
Use with a compatible flange face and appropriately selected gasket to achieve proper sealing performance.
Typical Applications
Water & Agricultural Systems
- Water distribution piping
- Irrigation systems
- Agricultural piping
- Pump connections
- General utility water systems
Commercial & Industrial Systems
- Mechanical piping
- Industrial utility systems
- Equipment connections
- Flanged valve installations
- General service piping
Threaded Flange vs. Weld Flange
Threaded Flange
A threaded flange connects directly to male-threaded pipe and does not require welding during normal installation.
Weld Flange
A weld flange is permanently joined to pipe by welding and may be preferred where a welded connection is required by the piping specification.
Our valve, fitting, and industrial product specialists can help review your valve size, FIP connection requirements, pressure rating, handle configuration, media compatibility, and application before you order.

Important Ordering & Installation Notes
- This listing is for Midland Class 150 Galvanized Threaded Ductile Iron Flanges.
- Available sizes range from 2" through 8".
- Confirm the required nominal flange and pipe thread size before ordering.
- Verify ANSI/ASME B16.5 dimensional compatibility.
- Confirm standard Class 150 bolt-pattern compatibility with the mating flange.
- Verify raised face compatibility with the intended flange assembly.
- Use an appropriate NPT thread sealant or PTFE tape where permitted.
- Avoid excessive thread tightening that could damage the flange or connected pipe.
- Select a gasket suitable for the media, pressure, temperature, and flange faces.
- Ensure mating flange surfaces are clean and properly aligned before assembly.
- Tighten flange bolts using an appropriate cross-pattern sequence.
- Do not use flange hardware to pull severely misaligned piping into position.
- Verify system pressure and temperature requirements before placing the connection into service.
- Install according to applicable piping standards, project requirements, and manufacturer recommendations.
