Tower flange: Expertly engineered for the robust connection of various sections within the wind turbine tower, this flange boasts a considerable diameter and substantial weight. It is meticulously designed to endure the impressive load of the wind turbine tower while offering exceptional anti-fatigue performance, ensuring a steadfast and resilient structure.
Hub flange: Integral to the union of the hub and tower apex, this flange masterfully withstands the substantial thrust and bending moments exerted by the wind turbine rotor. Its construction demands unparalleled strength and rigidity, meeting the rigorous standards necessary for optimal performance and durability.
Blade flange: Crafted with precision, this flange secures the blade root to the hub, featuring compact dimensions yet demanding utmost accuracy. It ensures the proper installation angle of the blade, facilitating the wind turbine's efficient operation and peak performance.
Tower foundation flange: Serving as a vital link between the tower foundation and the tower barrel, this flange predominantly bears the wind turbine's weight and the forces of nature. With built-in seismic resistance and anti-corrosion properties, it stands resilient against environmental challenges, guaranteeing longevity and stability.
Classification by installation position: This versatile flange system is categorized into internal and external flanges. Internal flanges are positioned on both sides of the fan's main shaft, adjacent to the generator set, while external flanges are strategically placed at the extremities of the main shaft, further from the generator, enhancing the overall structural integrity of the system.
Features
High strength: Specifically engineered to confront the forces of wind and rotational torque, these flanges exhibit superior strength and rigidity, ensuring the seamless, safe, and reliable operation of your wind power systems.
Strong corrosion resistance: Tailored for installation in marine and storm-prone regions, these flanges exhibit remarkable resilience against environmental elements such as seawater and harsh climates, maintaining their integrity and functionality over time.
Tight connection: Employing secure bolt fastenings, these flanges guarantee a robust connection between the fan impeller and main shaft, effectively withstanding substantial torque and vibration for reliable long-term performance.
Good lubricity: Designed for minimal friction and wear, these flanges require regular lubrication and maintenance, ensuring they remain in optimal working condition under high-speed rotation and challenging environmental conditions.
Detachability: Thoughtfully designed with a detachable structure, these flanges allow for swift disassembly and installation, facilitating easy maintenance and component replacement when necessary.
Good anti-fatigue performance: Built to endure continuous and long-term operational demands, these wind power flanges exhibit exceptional anti-fatigue properties, adeptly handling frequently fluctuating loads, thereby ensuring consistent and reliable performance.

Pressure Rating |
| Light-duty Flange |
Corresponding to Code 61 in ISO 6162-1 and SAE J518 standards, also known as the 3000psi flange. It is suitable for hydraulic systems with relatively low pressure and can generally withstand a pressure range from 3.5MPa (35bar) to 21MPa (210bar). |
| Heavy-duty Flange |
: Corresponding to Code 62 in ISO 6162-2 and SAE J518 standards, also known as the 6000psi flange. It is used in occasions with high pressure and can withstand a pressure range from 21MPa (210bar) to 42MPa (420bar) or even higher. |

Dimension Specification |
| Outer Diameter of the Flange |
It increases with the increase of the nominal diameter. For example, the outer diameter of a light-duty flange with a nominal diameter of DN10 may be 50mm, and the outer diameter of a light-duty flange with a nominal diameter of DN200 may be 340mm. |
| Bolt Hole Pitch |
The bolt hole pitch varies for flanges with different nominal diameters and pressure ratings. For instance, the bolt hole pitch of a DN10 flange may be 60mm, and that of a DN100 flange may be 180mm. |
| Bolt Diameter and Quantity |
The bolt diameters generally include M14, M18, M22, etc., and the number of bolts ranges from 4 to 20. For example, a DN25 flange may use M14 bolts, with a quantity of 4; a DN500 flange may use M26 bolts, with a quantity of 20. |
| Flange Thickness |
The thickness of a DN10 flange may be 14mm, and the thickness of a DN300 flange may reach 28mm or 32mm.
