3. Applications:This flange is widely used in marine & offshore engineering, seawater cooling systems, shipbuilding, oil & gas platforms, desalination plants, power generation, and petrochemical industries. Its excellent resistance to seawater corrosion and biofouling makes it the preferred choice for critical fluid handling systems.
4-5. Product Advantages & Functions:
Advantages: Superior seawater corrosion resistance, anti-biofouling, high strength-to-weight ratio, excellent weldability, and long service life with minimal maintenance. Forged construction ensures superior grain structure and mechanical properties.
Functions: Securely connects pipes, valves, pumps and equipment; provides pressure containment; enables easy system disassembly for inspection and maintenance.
6. Instructions & Precautions:
Installation: Clean socket and pipe end; insert pipe to socket shoulder; apply fillet welding using ERCuNi filler; use compatible gaskets; torque bolts evenly in cross-pattern sequence; conduct pressure test before service.
Precautions: Ensure material compatibility to avoid galvanic corrosion; control welding temperature; store in dry environment; handle carefully to protect sealing surfaces.
