Product Description

The reducing flange,

The reducing flange, also known as the eccentric reducer flange, is a type of flange pipe fitting used to connect pipes with different diameters. The following is a detailed introduction to the reducing flange: ### Structural Features - The structure of the reducing flange is similar to that of a common flange, which includes connection surfaces, bolt holes and other parts. However, its main feature lies in the fact that the pipe diameters at both ends are different, and the connection between pipes with different diameters is achieved through a gradual transition structure. The length and taper of the transition part vary according to different usage requirements and the range of pipe diameter changes. Generally speaking, the taper is designed to be relatively gentle to ensure the smooth flow of the fluid inside the pipe and reduce resistance and turbulence. ### Functions - **Connecting pipes with different diameters**: In the wind power generation system, due to the different design requirements for the pipe diameters of different parts, such as the ventilation pipes at different heights inside the tower cylinder and the pipes of different branches in the cooling system, the reducing flange can connect these pipes with different diameters to form a complete pipeline system. - **Adjusting the flow rate and pressure of the pipeline system**: By changing the diameter of the pipe, the flow rate and pressure of the fluid inside the pipe can be adjusted. In the cooling system of wind power equipment, the reducing flange can be used to adjust the flow rate of the pipes in different parts to ensure that each component receives an appropriate cooling effect. ### Material Selection - Similar to the materials of wind power flanges, reducing flanges usually also use steel materials such as carbon steel, alloy steel, and stainless steel. For some occasions with special requirements, such as in offshore wind power, in order to improve corrosion resistance, special materials such as nickel-based alloys with better seawater corrosion resistance may be selected. In some parts where there are requirements for weight, lightweight materials such as aluminum alloys will also be considered. ### Production Processes - **Forging**: For some reducing flanges with small diameters and high pressure resistance, the forging process is often used. Through forging, the internal structure of the material can be made denser, and the strength and toughness of the flange can be improved, ensuring its reliability in high-pressure and high-stress environments. - **Casting**: For reducing flanges with large diameters and complex shapes, the casting process is more commonly used. Reducing flanges of various shapes and sizes can be manufactured according to design requirements, which can meet the special needs of different projects. However, attention should be paid to controlling casting defects to ensure product quality. - **Welding**: First, the flange parts with different pipe diameters and the transition sections are manufactured separately, and then they are connected together through the welding process. This method can flexibly combine flanges of different specifications and is suitable for some non-standard specifications or small-batch production of reducing flanges. However, the welding quality has an important impact on the performance of the flange, and the welding process and quality need to be strictly controlled to ensure the strength and sealing performance of the welded joint. ### Applications in the Wind Power Field - Reducing flanges are widely used in the wind power field, mainly for connecting pipeline systems with different pipe diameters inside the tower cylinder, such as cable protection pipes, hydraulic oil pipes, and compressed air pipes. They can also be used for the pipeline connection of the cooling system, lubrication system, and pitch system of the wind turbine to achieve the fluid transportation and pressure transfer between different components. During the installation and maintenance of wind power equipment, the detachable structure of the reducing flange facilitates the assembly and maintenance of the pipeline system, improving work efficiency.
