Stainless Steel Flanges

Amardeep Steel is a leading Stainless Steel Flanges Manufacturer in India, specializing in high-quality stainless steel flanges for industries such as oil, gas, food, and chemicals. Our range includes SS Blind Flanges, which are designed to close off pipelines securely. These flanges can be either permanently welded or temporarily bolted, allowing for convenient maintenance. Available in sizes from ½ inch to 48 inches nominal bore size, our flanges also offer various pressure classes, ranging from 150 to 2500 and PN6 to PN64, ensuring they meet the demands of high-pressure systems.

We offer multiple stainless steel flange types, including Welded Neck-Raised Face Flanges and Threaded Pipe Flanges. Welded neck flanges provide robust support, holding pipes securely during welding, while their raised face design allows for reliable attachment using bolts or welding. The Threaded Pipe Flange, known for its strength and corrosion resistance, is easy to assemble and disassemble without welding, making it ideal for setups requiring regular maintenance. Additionally, SS Slip-On Flanges provide a cost-effective, low-pressure solution, sliding over pipes and welding from both the inside and outside for secure connections.

Our stainless steel flanges are made from diverse materials, including ferritic, austenitic, duplex, and alloy steels, each suited for specific environments. Ferritic stainless steel offers superior high-temperature resistance, perfect for demanding applications, while austenitic stainless steel provides excellent corrosion resistance in moisture-rich and chemical-prone conditions. As a trusted Stainless Steel Flange Manufacturer in India, we supply flanges in multiple standards, specifications, and dimensions to suit various industrial requirements.

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.

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
