HT PIPE supply all different types and scales of flanges. Please feel free to contact us for further product information and pricing.
Core Characteristics of Ni200 Material
Corrosion Resistance: The annual corrosion rate is <0.01mm in strong alkaline solutions below 300℃, and it exhibits excellent resistance to corrosive media such as hydrofluoric acid and anhydrous hydrogen chloride. It can withstand neutral and reducing environments and seawater corrosion, far exceeding carbon steel and ordinary stainless steel materials.
Dense and Stable Structure: Manufactured using a forging process, it is free of pores and shrinkage defects, possesses excellent mechanical strength, and has good ductility and weldability, ensuring the long-term stable operation of the piping system.
Temperature Adaptation Range: Suitable for operating conditions ≤315℃, with stable mechanical properties at room temperature, avoiding material embrittlement problems in high-temperature environments. This creates a clear operating condition distinction with low-carbon Ni201 (Ni201 is suitable for scenarios >315℃).
Functional Advantages of ni200 Spectacle Blind Flange
Quick Switching Operation: No need to disassemble bolts. simply rotate 90° to switch between "flow" and "isolation" states, significantly improving pipe maintenance and process switching efficiency, and reducing labor and downtime costs.
Secure Isolation Guarantee: The blind plate end provides complete physical isolation with excellent sealing performance, effectively preventing leakage of toxic and corrosive media, especially suitable for flammable and toxic media piping systems.
Intuitive State Indication: The 8-shaped structure allows for direct visual identification of the current working state, avoiding the risk of misoperation and improving the safety of pipeline system operation and maintenance.
