Product Advantage
1. High-Strength Material with Strong Reliability
The flange is made of high-quality forged materials, with heat treatment enhancing its strength and toughness to ensure long-term stable operation under high-pressure and high-impact loads.
2. Precision Machining Ensuring Excellent Sealing Performance
Key sealing and mating surfaces are machined with high-precision CNC equipment, with strict control of flatness and coaxiality to achieve zero-leak sealing.
3. Multi-Standard Compatibility for Strong System Integration
The product covers major domestic and international standards such as DIN, ISO, and GB, allowing flexible connection with various piping systems and convenient global application.
4. Corrosion-Resistant Treatment Extending Service Life
Surface treatments such as galvanizing, electrophoresis, powder coating, and phosphating are available upon request to improve oxidation and corrosion resistance, especially suitable for humid and harsh environments.
5. Diverse Structural Types Supporting Custom Non-Standard Orders
Various flange types are available, including welded flanges, threaded flanges, blind flanges, and split flanges. Non-standard customization (dimensions, bolt hole patterns, connection interfaces, etc.) is supported to meet diverse customer requirements across different equipment and installation scenarios.

Product Uses
1. Hydraulic Systems in Construction Machinery
Widely used in construction machinery such as excavators and loaders, these flanges connect high-pressure hydraulic hoses between hydraulic cylinders, pumps, and control valves, ensuring efficient and safe system operation.
2. Marine and Offshore Engineering Equipment
Applied in ship hydraulic systems including steering gear, lifting platforms, and cranes, these flanges meet stringent requirements for corrosion resistance and sealing performance to withstand high humidity and saline environments.
3. Metallurgical and Heavy Industry Equipment
Used in large metallurgical machinery such as continuous casting machines, rolling mills, and hydraulic presses, these flanges ensure stable operation under high temperature and heavy load conditions within high-pressure hydraulic circuits.
4. Wind Power and New Energy Equipment
Implemented in hydraulic regulation systems and tower lifting mechanisms of wind turbines, these flanges require excellent vibration resistance and sealing stability to maintain reliable performance.
Product Operate Guide
1. Before installation, confirm the flange model matches the system pipeline. Inspect and clean the flange surface to prevent foreign materials from affecting the seal.
2. Properly place the sealing ring into the flange groove. Align the connecting pipe with the flange mounting holes, ensuring it is perpendicular and without misalignment. Use a torque wrench to tighten bolts evenly according to the recommended torque values.
3. Before starting the hydraulic system, check for any obvious looseness at the flange connection. After pressurizing the system, observe for any oil seepage or leaks.
4. Regularly inspect the flange connection area. If rust is found on the surface, clean it promptly and apply anti-rust oil.
