Wind Power Hydraulic Pipe Flange for Foundation Ring

Product Description

Product Description

Tower flange: It is used to connect the various sections of the wind turbine tower. It has a relatively large diameter and heavy weight, and it is necessary to consider its ability to withstand the load of the wind turbine tower and its anti-fatigue performanceHub flange: It connects the hub and the top of the tower. It has to bear the thrust and bending moment from the wind turbine rotor, so it has high requirements for strength and stiffness.Blade flange: It is used to connect the root of the blade to the hub. It has relatively small dimensions but requires a high degree of precision to ensure the correct installation angle of the blade and the efficient operation of the wind turbine
Tower foundation flange: It connects the tower foundation and the tower barrel, mainly bearing the weight of the wind turbine itself and the force exerted by the wind. It has seismic resistance and anti-corrosion capabilities.Classification by installation position: It can be divided into internal flanges and external flanges. The internal flange refers to the flange set on both sides of the main shaft of the fan, close to the generator set. The external flange is installed at both ends of the main shaft of the fan, at a position far from the generator set.
Features
High strength: It needs to withstand wind force and rotational torque, and has high strength and stiffness to ensure safe and reliable operation.
Strong corrosion resistance: Usually installed in marine or storm-prone areas, it should be able to resist the erosion of environmental factors such as seawater and climate.
Tight connection: Generally, bolts are used for fastening connection to ensure a firm connection between the fan impeller and the main shaft, and at the same time, it can withstand large torque and vibration.
Good lubricity: Regular lubrication and maintenance are required to reduce friction and wear, and maintain a good working state under high-speed rotation and harsh environments.
Detachability: For the convenience of maintenance and replacement of components, it is usually designed as a detachable structure, which can be quickly disassembled and installed.
Good anti-fatigue performance: Since the wind turbine generator set operates continuously for a long time, the wind power flange needs to have good anti-fatigue performance to withstand frequently fluctuating loads.
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.
