Stainless Steel Flange Reliable Industrial Pipe Fitting Solution

A stainless steel flange is a critical component used for connecting piping systems. Made from high-quality stainless steel, it is designed for pipe joints that require frequent disassembly. Known for its excellent corrosion resistance, high strength, and long service life, stainless steel flange are widely used in industries such as oil & gas, food processing, pharmaceuticals, water treatment, and energy.

Main Types of Stainless Steel Flange

The most common types of stainless steel flange include:

1. Slip-On Flange: Simple structure, easy to install, suitable for low-pressure applications
2. Weld Neck Flange: High strength and superior sealing performance, ideal for high-pressure and high-temperature environments
3. Socket Weld Flange: Best for small-diameter piping systems
4. Lap Joint Flange: Allows easy alignment, often used in systems requiring frequent disassembly
5. Blind Flange: Used to seal the end of a pipeline

Material Selection for Stainless Steel Flange

Different grades of stainless steel determine the flange’s performance:

• 304 Stainless Steel Flange: General-purpose, good corrosion resistance and machinability
• 316 Stainless Steel Flange: Contains molybdenum, offering enhanced corrosion resistance, especially in marine environments
• 321 Stainless Steel Flange: Titanium-stabilized, excellent for resisting intergranular corrosion
• Duplex Steel Flange: Combines high strength and superior corrosion resistance for harsh conditions

Key Advantages of Stainless Steel Flange

1. Superior Corrosion Resistance: Resists chemical erosion, ensuring long-term durability
2. High Strength: Withstands high pressure and extreme temperatures for safe operation
3. Hygienic Properties: Smooth surface prevents contamination, meeting food and pharmaceutical industry standards
4. Aesthetic & Durable: Maintains a polished appearance, ideal for visible installations
5. Eco-Friendly & Recyclable: 100% recyclable, aligning with sustainable practices
