Product Description

Product Description

Tower flange: Serving as the crucial connector between various segments of the wind turbine tower, the tower flange boasts a significantly large diameter and weight. It is meticulously engineered to endure immense loads imposed by the towering structure and exhibits exceptional anti-fatigue capabilities to ensure long-lasting performance under continuous operational stress.Hub flange: This critical component acts as the pivotal link between the hub and the tower's apex. Designed to withstand the substantial thrust and bending forces generated by the dynamic wind turbine rotor, the hub flange is crafted with stringent strength and stiffness requirements, ensuring unwavering stability and optimal energy capture efficiency.Blade flange: Specifically designed to affix the blade root securely to the hub, this flange may appear modest in size but demands a high degree of precision. This precision ensures accurate blade installation angles, facilitating the wind turbine's seamless operation and maximizing energy production efficiency.
Tower foundation flange: Acting as the steadfast connection between the tower foundation and the tower barrel, this flange bears the substantial weight of the entire wind turbine assembly. Engineered with seismic resistance and anti-corrosion attributes, it provides unwavering support against environmental forces, ensuring durability and stability.Classification by installation position: Flanges are categorized into internal and external types based on their installation position. Internal flanges are strategically placed near the generator set, flanking the fan's main shaft. Conversely, external flanges are positioned distally, anchoring the main shaft's ends far from the generator set, ensuring robust structural integrity.
Features

High strength: Engineered to withstand formidable wind forces and rotational torque, these flanges exhibit unparalleled strength and stiffness, guaranteeing safe, reliable operation amidst the harshest wind conditions.
Strong corrosion resistance: Installed in challenging marine or storm-prone locales, these flanges are fortified to resist environmental eroding agents such as seawater and harsh climatic elements, ensuring longevity and durability.
Tight connection: Employing robust bolt fastening methods, these flanges ensure a steadfast connection between the fan impeller and main shaft, adeptly withstanding high torque and intense vibration for secure and stable performance.
Good lubricity: Regular and meticulous lubrication and maintenance are essential to minimize friction and wear. This ensures sustained peak performance even under high-speed rotation and demanding environmental conditions.
Detachability: Designed with user-friendly detachability, these flanges allow for swift and effortless disassembly and installation, facilitating convenient maintenance and component replacement.
Good anti-fatigue performance: Withstanding continuously fluctuating loads inherent in long-term wind turbine operation, these flanges are engineered with excellent anti-fatigue properties, ensuring prolonged operational resilience and reliability.

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.
