Tower Flange: An essential component for wind turbine towers, this tower flange boasts a substantial diameter and weight, crafted to endure the immense loads and stress imposed by wind turbine towers. Its robust design emphasizes outstanding load-bearing capabilities and exceptional anti-fatigue performance, ensuring the turbine's stability and durability even under the harshest conditions.
Hub Flange: This crucial connector between the hub and the tower top is engineered to handle the impressive thrust and bending moments from the wind turbine rotor. Built with superior strength and stiffness, it meets the highest standards, providing the necessary resilience to withstand the dynamic forces of wind power generation.
Blade Flange: Precision-designed to join the blade root to the hub, this flange demands meticulous accuracy to secure the blade at the perfect angle, maximizing efficiency and optimizing turbine performance. Despite its compact size, it plays a pivotal role in ensuring seamless and effective wind turbine operation.
Tower Foundation Flange: Serving as the link between the tower foundation and the tower barrel, this flange is vital for supporting the weight of the entire wind turbine and counteracting wind forces. Not only is it equipped with seismic resistance, but it also features advanced anti-corrosion properties, guaranteeing long-lasting performance in challenging environments.
Classification by Installation Position: Wind power flanges are categorized into internal and external types. Internal flanges are strategically placed on both sides of the fan's main shaft, near the generator set, while external flanges are positioned at the far ends, away from the generator set, providing versatile and adaptable installation options.
Features
High Strength: Engineered to withstand formidable wind forces and rotational torque, these flanges exhibit exceptional strength and stiffness, ensuring the safe and reliable operation of wind turbines under any conditions.
Strong Corrosion Resistance: Designed for use in harsh environments such as marine or storm-prone regions, this flange is fortified against the corrosive effects of seawater and extreme climates, ensuring longevity and reliability.
Tight Connection: Utilizing robust bolt fastening, these flanges provide a secure and steadfast connection between the fan impeller and the main shaft, capable of handling significant torque and vibration with ease.
Good Lubricity: By facilitating regular lubrication and maintenance, these flanges effectively minimize friction and wear. They guarantee optimal operation under high-speed rotation and severe environmental conditions, preserving the turbine's performance.
Detachability: Engineered for ease of maintenance and component replacement, these flanges feature a detachable structure, allowing for straightforward and swift disassembly and installation.
Good Anti-Fatigue Performance: Designed to withstand the continuous, dynamic loads experienced during prolonged operation, these flanges showcase excellent anti-fatigue properties, ensuring consistent performance and durability.

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.
