Stainless Steel Flange & Fittings Manufacturers, Suppliers, And Stockist In India.
Nishit Overseas is one of the most leading Stainless Steel Flange & Fittings Manufacturers in India. For applications demanding high durability and corrosion resistance, stainless steel flanges and fittings are often ideal choices. Stainless steel provides enhanced longevity compared to hot-dip galvanized steel due to its superior strength and resistance to corrosion. When selecting the appropriate stainless steel flanges and fittings, consider the manufacturing technique—commonly forged, cast, or cut—and choose the grade that best suits your specific application.

About Stainless Steel Flanges
Stainless steel flanges are crucial components in piping systems used across various industries. They provide a secure and reliable connection between pipes, valves, pumps, and other equipment, ensuring the integrity and efficiency of fluid or gas transport.
Types of Flanges we stock and supply :
1. Weld Neck Flange:
• Designed for high-pressure systems, welded to the pipe.
• Offers high strength and durability.
2. Slip-On Flange:
• Slides over the pipe and is then welded.
• Easy to install and cost-effective for low-pressure applications.
3. Socket Weld Flange:
• Pipe is inserted into a socket in the flange and then welded.
• Provides a secure fit and is used for small-diameter pipes.
4. Blind Flange:
• Used to close the end of a pipe system.
• No opening in the center, used for pressure testing or sealing.
5. Threaded Flange:
• Screws onto the pipe without welding.
• Ideal for low-pressure and non-welding applications.
6. Lap Joint Flange:
• Works with a stub end, allowing for easy removal and replacement.
• Ideal for systems requiring frequent disassembly.
7. Orifice Flange:
• Incorporates an orifice plate for flow measurement.
• Used in systems where flow rate needs to be monitored.
Materials and Grades:
• Common grades include 304 and 316 stainless steel.
• 304 is general-purpose, while 316 offers superior corrosion resistance, particularly against chlorides and acids.
About Stainless Steel Fittings
Stainless steel fittings are essential components in various piping systems, ensuring secure, leak-proof connections between pipes, tubes, and other equipment. They are highly valued for their durability, resistance to corrosion, and ability to withstand high pressures and temperatures.
Types of Stainless Steel Fittings
1. Elbows:
• Function: Change the direction of flow within a piping system.
• Types: 45°, 90°, and 180° bends.
• Applications: Used in plumbing, chemical processing, and food industries.
2. Tees:
• Function: Connects three pipe sections, allowing fluid to flow in multiple directions.
• Types: Equal (straight) tees and reducing tees.
• Applications: Commonly used in branching pipeline systems.
3. Reducers:
• Function: Reduces the pipe size from a larger to a smaller bore.
• Types: Concentric (centered) and eccentric (offset).
• Applications: Used where pipe diameter changes are needed.
4. Couplings:
• Function: Connects two pipes or tubes together.
• Types: Full coupling, half coupling, and reducing coupling.
• Applications: Plumbing and industrial piping systems.
5. Adapters:
• Function: Connects pipes or tubes of different types or sizes.
• Types: Male and female adapters.
• Applications: Used to transition between different piping systems.
6. Caps:
• Function: Covers the end of a pipe, closing it off.
• Types: Threaded and socket-weld caps.
• Applications: Temporary or permanent pipe closure.
7. Bushings:
• Function: Reduces the size of a pipe fitting’s threaded opening.
• Types: Hex and flush bushings.
• Applications: Used in plumbing to adapt the size of a fitting.
8. Crosses:
• Function: Connects four pipe sections, forming a cross shape.
• Applications: Typically used in fire sprinkler systems.
9. Unions:
• Function: Allows quick disconnection of pipes for maintenance.
• Types: Threaded and socket-weld unions.
• Applications: Ideal for pipelines requiring frequent disassembly.
10. Nipples:
• Function: Short lengths of pipe with threads at both ends for connection.
• Types: Close, short, and long nipples.
• Applications: Used to connect fittings or extend pipe length.
Material Grades
• 304 Stainless Steel: Most common grade, offers good corrosion resistance and is suitable for most applications.
• 316 Stainless Steel: Provides superior resistance to chlorides and other corrosive substances, ideal for marine and chemical environments.
• Other Grades: 321, 347, and duplex stainless steels for specialized applications requiring higher temperature resistance or enhanced strength.
