Product Description

Product Description

Tower Flange: This robust component is essential for connecting various sections of the wind turbine tower. With its substantial diameter and weight, it is engineered to withstand the immense load of the wind turbine tower, while boasting superior anti-fatigue characteristics.Hub Flange: The linchpin that connects the hub and the tower's pinnacle, this flange endures the thrust and bending moments exerted by the wind turbine rotor. Its impeccable strength and stiffness make it indispensable for optimal performance.Blade Flange: Designed to connect the blade root to the hub, this flange, with its compact dimensions, demands exceptional precision to guarantee the accurate installation angle of the blade, fostering efficient wind turbine operation.
Tower Foundation Flange: This critical flange connects the tower foundation to the tower barrel, primarily supporting the weight of the wind turbine and resisting forces from the wind. It is distinguished by its seismic resistance and anti-corrosion properties.Classification by Installation Position: Flanges are categorized into internal and external types. Internal flanges are mounted close to the generator set on both sides of the main shaft, while external flanges are positioned at both ends of the main shaft, further from the generator set.
Features

High Strength: Designed to endure formidable wind forces and rotational torque, these flanges possess superior strength and stiffness, ensuring the wind turbine's safe and reliable operation.
Strong Corrosion Resistance: Strategically crafted for installation in marine or storm-laden environments, they are fortified to resist the relentless erosion from seawater and climatic extremities.
Tight Connection: Utilizing bolts for secure fastening, these flanges guarantee a steadfast connection between the fan impeller and the main shaft, adeptly handling considerable torque and vibration.
Good Lubricity: Regular lubrication and meticulous maintenance are essential to minimize friction and wear, preserving an optimal operational state even under high-speed rotation and severe conditions.
Detachability: Engineered with a detachable design for straightforward maintenance and component replacement, these flanges allow for rapid disassembly and installation, enhancing operational efficiency.
Good Anti-Fatigue Performance: Built for the long-haul, these flanges exhibit outstanding anti-fatigue performance, crucial for enduring the constantly fluctuating loads of continuous wind turbine operations.

Product Parameters

	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.
	Nominal Diameter
DN13 to DN127	The nominal diameter range of hydraulic pipe flanges is usually between DN13 and DN127. For example, DN13 corresponds to 1/2 inch, DN25 corresponds to 1 inch, DN50 corresponds to 2 inches, and so on.
	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.
