ASTM A182 Weld Neck Flange | Stainless Steel Pipe Flange Price List | Ferritic Stainless Steel Flanges Manufacturers in India
Amardeep Steel is a leading Stainless Steel Flanges Manufacturer in India. Stainless steel flanges are vital components in various industrial processes, serving as connectors or joint pieces between pipes, valves, and other equipment. Made from a blend of iron, chromium, and nickel, stainless steel flanges boast exceptional strength and resistance to corrosion, making them suitable for use in harsh environments. Stainless steel flanges come in different shapes and sizes to suit the diverse needs of industries such as oil and gas, chemical processing, pharmaceuticals, water treatment, etc. Stainless steel flanges also offer excellent sealing capabilities to prevent leakages and ensure a safe working environment.
Stainless steel flanges are made from stainless steel, a steel alloy containing chromium and other metals that give it superior corrosion resistance. The Stainless Steel Pipe Flange is used to close a pipeline in these industries. The blind flange can be permanently fixed with welding or temporarily fixed by bolting for easy maintenance and removal. SS Flanges come in different sizes ranging from ½ inches to 48 inches in nominal bore size. There are also different types such as the SS Blind Flange Dimension belonging to different pressure classes. The pressure classes vary from 150 to 2500 and PN6 to PN64.
These indicate the maximum pressure each flange can withstand while in operation. We manufacture duplex flanges in a variety of diameters, ranging from 1/2 NPS to 40 NPS (15 NB to 1000 NB) as requested by the client.
The high-temperature resistance of the Stainless Steel Exhaust Flanges makes them applicable to high-temperature applications. There are different types of flanges in different grades such as Stainless Steel Header Flanges and other types. The flanges could be welded, bolted, or screwed as a means of connection. The screwed Stainless Steel Screwed Flanges are used where bolting with nuts or welding is not applicable or not preferred.
Stainless Steel Flanges Price
The stainless steel flange price varies based on factors such as material grade, size, and type of flange required for specific applications. High-quality stainless steel flanges are preferred for their durability, corrosion resistance, and suitability for a range of industries, including oil and gas, construction, and chemical processing. When considering the stainless steel flanges price, it is essential to choose reliable manufacturers offering certified products that meet industry standards.
Types of Stainless Steel Flanges by Amardeep Steel
Amardeep Steel is a leading supplier of precision-engineered stainless steel flanges, catering to industries where reliable, high-performance connections are essential. We manufacture a comprehensive range of flanges in various designs, materials, and pressure classes to meet specific engineering requirements. Here’s an overview of the key types of flanges we offer:
Blind Flange
The Blind Flange is a solid disk without a central hole, designed to close off piping systems or vessels. Commonly used for inspection ports, this flange provides a secure barrier to prevent flow while allowing access for maintenance. Our stainless steel blind flanges are available in pressure ratings from Class 150 to 2500 and are compatible with various pipe sizes, making them ideal for systems requiring periodic closure or testing.
Weld Neck Flange
The Weld Neck Flange from Amardeep Steel features a long, tapered hub that provides reinforcement and reduces stress concentration, making it suitable for high-pressure and high-temperature applications. This flange has a matching bore to the pipe, which ensures smooth, uninterrupted flow and reduces turbulence in critical applications such as oil and gas pipelines, refineries, and petrochemical plants. It’s available in pressure classes up to Class 2500 and meets ASTM A182 standards for strength and durability.
Slip-On Flange
Designed for ease of installation, the Slip-On Flange slips directly over the pipe and is welded on both the inner and outer surfaces, creating a secure seal. This cost-effective flange is ideal for low-pressure applications in systems where durability is needed without the need for extensive welding. It’s available in a range of nominal sizes and pressure classes and offers compatibility with a variety of pipe schedules.
Socket Weld Flange
The Socket Weld Flange is engineered for smaller, high-pressure pipes, making it an optimal choice for precision systems. The pipe fits into a recessed area or socket in the flange, allowing for a smooth bore and reducing flow restrictions. This design is widely used in applications requiring a leak-proof connection in high-pressure environments, including chemical processing and instrumentation lines.
Threaded Flange
With internal tapered threads, the Threaded Flange allows easy attachment to pipes without the need for welding. This flange type is best suited for low-pressure applications where welding may be impractical, such as in explosive environments. Amardeep’s threaded flanges are manufactured to precise specifications, ensuring a secure fit and easy installation in configurations that may require periodic disassembly.
Lap Joint Flange
The Lap Joint Flange is used with a stub-end fitting, allowing it to rotate freely for easy alignment and frequent dismantling. It is ideal for low-pressure, non-critical applications where regular maintenance is required, such as in food processing and water treatment facilities. This flange type provides flexibility and easy installation, helping to reduce alignment and maintenance time.
Amardeep Steel’s flanges are made from premium stainless steel grades (ferritic, austenitic, duplex, and alloy steels) to meet stringent quality and performance standards, ensuring longevity even in the most demanding environments. Contact us for technical specifications, pricing, and detailed consultation on choosing the right flange for your project’s needs.

Top Industries for Stainless Steel Flange Applications
Oil & Gas Industry
Stainless steel flanges are essential in the oil and gas sector due to their exceptional strength and corrosion resistance. In this industry, flanges are required to withstand extreme pressures and temperatures in pipelines and drilling rigs. The material’s resistance to harsh chemicals and high-stress environments ensures reliability and safety in transporting oil, gas, and other petroleum products.
Chemical Processing
In chemical processing plants, stainless steel flanges connect pipes and vessels handling hazardous and corrosive substances. Their chemical stability prevents reactions that could compromise equipment integrity. Flanges made of grades like 316 stainless steel, containing molybdenum, provide enhanced corrosion resistance, which is crucial for the longevity and safety of chemical processing equipment.
Food & Beverage Industry
Stainless steel flanges are ideal for the food and beverage industry, where hygiene and purity are paramount. The smooth, non-porous surface of stainless steel prevents bacterial growth and contamination, ensuring compliance with health and safety standards. These flanges are commonly used in sanitary piping and processing equipment, providing a reliable, corrosion-resistant solution for food-grade applications.
Power Generation
In power plants, stainless steel flanges connect critical components in high-temperature environments, such as boilers, turbines, and heat exchangers. The mechanical properties of stainless steel, including high tensile strength and heat resistance, make it suitable for applications that involve extreme stress and thermal variations. This durability ensures continuous, safe operations in power generation facilities
