Incoloy 800 Slip-On Flange BS 4504 5”
📌 Product Name
Incoloy 800 Slip-On Flange, BS 4504, 5"
📄 Product Description
The Incoloy 800 Slip-On Flange is designed according to BS 4504 standards and is intended for 5-inch pipe sizes. Made from Incoloy 800, a high-performance nickel-iron-chromium alloy, this flange is designed for easy installation. The slip-on design allows the flange to be slid over the pipe and then welded in place. This design offers excellent strength and corrosion resistance, making it suitable for high-temperature and highly corrosive environments. It is commonly used in industries such as petrochemical, power generation, and chemical processing.
⭐ Material Characteristics (Incoloy 800)
Composition: Approximately 32% Nickel, 21% Chromium, Iron-based
Heat Resistance: Superior performance in the temperature range of 600°C to 1100°C
Oxidation Resistance: Excellent resistance to oxidation, carburization, and sulfidation
Corrosion Resistance: Resistant to corrosion in acidic, alkaline, and saltwater environments
Structural Stability: Maintains austenitic microstructure even at high temperatures
Weldability: Good weldability, easy to work with during installation
✅ Advantages
Ease of Installation: The slip-on design simplifies the installation process, allowing the flange to be fitted onto the pipe and welded securely in place
High-Temperature Performance: With its high-temperature resistance, it is ideal for use in power plants and heat exchangers
Corrosion Resistance: Excellent resistance to a wide range of aggressive environments such as acids, alkalis, and seawater
Cost-Effective: The slip-on design is generally more affordable than other flange types, such as weld neck flanges
Versatility: Can be used in a variety of industries, including chemical processing, petrochemical, and power generation
⚠️ Disadvantages
Pressure Limitations: While suitable for many applications, slip-on flanges are not ideal for extremely high-pressure systems
Leakage Potential: If not installed correctly or if welding is poor, slip-on flanges may have a higher potential for leakage compared to more robust designs like weld neck flanges
Alignment Sensitivity: Requires precise alignment during installation to avoid stress on the pipe and flange
🛠️ Applications
Chemical and petrochemical plants
Power generation systems
Heat exchangers and furnaces
Marine and offshore applications
Water treatment plants
Food processing equipment
