An MS Flange refers to a Mild Steel Flange, a critical component used in piping systems to connect pipes, valves, pumps, and other equipment. These flanges are made from mild steel, known for its strength, durability, and cost-effectiveness, making them widely used in industries such as oil & gas, water treatment, power plants, and construction.
What is an MS Flange?
An MS Flange is a flat, round, or square plate with holes for bolts. It is welded or screwed onto a pipe end to connect different pipeline sections or equipment. Unlike stainless steel or galvanized flanges, MS Flanges are preferred for their affordability and machinability.
Types of MS Flanges
MS Flanges come in different types depending on their applications and connection methods:
1. MS Blind Flange
Used to close the end of a pipe to stop flow.
Ideal for pipeline maintenance and pressure testing.
2. MS Slip-On Flange
Slides over the pipe and is then welded.
Cost-effective and easy to install.
3. MS Weld Neck Flange
Has a long neck for welding, providing strong and leak-proof connections.
Common in high-pressure and high-temperature applications.
4. MS Threaded Flange
Screwed onto pipes without welding.
Best suited for low-pressure applications.
5. MS Socket Weld Flange
A pipe is inserted into the socket and welded for increased strength.
Used in small-diameter, high-pressure pipelines.
6. MS Lap Joint Flange
Used with a stub end, allowing easy rotation and alignment.
Suitable for frequent dismantling applications.
Industrial Applications of MS Flanges
MS Flanges are used in various industrial sectors due to their cost-effectiveness and adaptability. Some key applications include:
1. Oil & Gas Industry
Used in pipelines, refineries, and drilling operations.
Handles high-pressure and high-temperature environments.
2. Water Treatment Plants
MS Flanges help in water distribution and sewage treatment systems.
Used in pumping stations, reservoirs, and filtration units.
3. Power Plants
Used in steam, cooling water, and gas transmission.
Provides secure and efficient connections in high-energy systems.
4. Construction and Infrastructure
Essential for HVAC systems, building pipelines, and structural supports.
Helps in drainage and gas distribution networks.
5. Chemical & Fertilizer Industry
Used in pipelines transporting corrosive fluids and gases.
Ensures safety and efficiency in chemical processing plants.
6. Shipbuilding & Marine Industry
MS Flanges are used in ship pipelines and offshore structures.
Resistant to moderate corrosion and mechanical stress.
Advantages of MS Flanges
MS Flanges offer several benefits, making them an excellent choice for industrial applications:
1. Cost-Effective
Mild steel is cheaper than stainless steel or alloy flanges.
Provides good strength and durability at an affordable cost.
2. Easy to Weld and Machine
MS Flanges can be easily cut, welded, and fabricated.
Ideal for custom piping solutions.
3. Good Strength and Durability
Capable of withstanding moderate pressure and temperature.
Reliable for long-term industrial use.
4. Versatility in Applications
Used in various industries, from construction to power plants.
Suitable for liquid, gas, and solid material transportation.
5. Corrosion Resistance with Coating
MS Flanges can be galvanized or coated to prevent rusting.
Extends the lifespan of flanges in harsh environments.
MS Flange Dimensions
MS Flanges come in various sizes, typically following ANSI, ASME, and IS standards. Below is a standard dimension chart:
| Nominal Pipe Size (NPS) | Flange Diameter (mm) | Bolt Hole Diameter (mm) | Number of Bolts |
|---|---|---|---|
| 1/2" | 90 | 15 | 4 |
| 1" | 125 | 19 | 4 |
| 2" | 150 | 19 | 4 |
| 4" | 230 | 19 | 8 |
| 6" | 280 | 22 | 8 |
| 8" | 345 | 22 | 8 |
| 10" | 405 | 25 | 12 |
