MS Threaded Flanges
MS Threaded Flanges are mild steel pipe flanges designed to create a detachable connection between threaded pipes, valves, equipment and other compatible piping components. They are useful in applications where welding is not preferred or where a threaded connection is required.
MS threaded flanges are commonly considered for industrial piping, water supply, plumbing, utility systems, engineering and fabrication applications. The correct flange should be selected according to pipe size, thread specification, pressure requirements, material compatibility and the intended application.

Applications of MS Threaded Flanges
Industrial Piping
MS threaded flanges can be used for connecting compatible threaded pipes with valves, equipment and other piping components.
Water Supply Systems
Suitable threaded flanges can be used in compatible water piping systems where a bolted and detachable connection is required.
Plumbing Applications
They can be considered for plumbing and utility installations where threaded pipe connections are used.
Engineering & Fabrication
MS threaded flanges are useful in fabricated piping assemblies and equipment connection applications.
Utility Systems
They may be used in suitable air, water and other utility piping systems, subject to the flange's specifications and media compatibility.
How Does an MS Threaded Flange Work?
An MS threaded flange has an internally threaded bore designed to engage with a compatible externally threaded pipe. The flange can then be bolted to another flange or compatible equipment connection using the appropriate gasket and fasteners.
This creates a detachable connection that can be useful for installation, inspection and maintenance.
MS Threaded Flanges vs Weld Neck Flanges
The main difference is the method of connecting the flange to the pipe.
MS Threaded Flange:
Uses an internal thread to connect with a compatible threaded pipe.
Weld Neck Flange:
Is designed to be welded to the pipe and is commonly selected for applications where a welded flange connection is required.
The appropriate flange depends on the piping design, pressure, temperature, installation method and project specifications.
How to Choose the Right MS Threaded Flange?
Before purchasing, check:
1. Pipe Size
Confirm the nominal pipe size and required flange dimensions.
2. Thread Specification
The flange thread must match the pipe thread specification.
3. Pressure Rating
Select a flange suitable for the system's pressure requirements.
4. Material Compatibility
Ensure mild steel is appropriate for the operating environment and service conditions.
5. Bolt Pattern
Check the bolt-hole arrangement and dimensions against the mating flange.
6. Gasket Requirements
Select a compatible gasket according to the piping system and operating conditions.
7. Application
Consider whether the flange is intended for water, air, industrial utility or another compatible service.

Frequently Asked Questions
What are MS threaded flanges?
MS threaded flanges are mild steel flanges with an internal threaded connection designed to connect compatible threaded pipes to flanged piping systems, valves or equipment.
What are MS threaded flanges used for?
They are used in suitable industrial piping, plumbing, water supply, engineering, fabrication and utility applications where a threaded pipe connection is required.
Do MS threaded flanges require welding?
A threaded flange is designed to connect to a compatible externally threaded pipe without welding the flange directly to the pipe. However, the complete piping installation must follow the applicable design and safety requirements.
What is the difference between a threaded flange and a slip-on flange?
A threaded flange connects to a threaded pipe, while a slip-on flange is designed to fit over the pipe and is normally welded into the piping assembly.
How do I select an MS threaded flange?
Check the pipe size, thread specification, pressure rating, flange dimensions, bolt pattern, material and application requirements.
Can MS threaded flanges be used for water pipelines?
Suitable MS threaded flanges can be used in compatible water piping systems. The exact flange specifications and operating conditions should be verified before installation.
What thread should an MS threaded flange have?
The thread should match the thread standard and specification of the pipe being connected. Always verify the required thread type before ordering.
Where can I buy MS threaded flanges?
MS threaded flanges can be purchased from industrial flange and pipe-fitting suppliers. When enquiring, provide the required size, thread specification, pressure rating and quantity.
