FAQ
The manufacturing process of flanges includes steps such as material selection, forging or casting, and heat treatment. Flanges are widely used in pipeline engineering for the connection of pipelines, especially for installing flanges on pipelines that need to be connected, and the connection is achieved by adding sealing points and tightening with bolts. Flanges of different pressures have different thicknesses and use different bolts. In addition, components such as water pumps and valves will also be connected using corresponding flange shapes.
● Flat flange: The sealing surface is a plane, with a simple structure and easy processing. It is suitable for occasions where the pressure is not high and the medium is non-toxic. The sealing is mainly achieved through the gasket between the flanges.
● Butt-welded flange: The neck height is high, which improves the rigidity and bearing capacity of the flange. It is suitable for high-temperature, high-pressure and low-temperature pipeline connections, and has good sealing performance and strong rigidity.
● Threaded flange: The connection is achieved through the cooperation of internal and external threads. It is easy to install and disassemble. It is suitable for low-pressure pipeline connections that often need to be disassembled, but is generally not used in high-pressure or high-temperature occasions.
● Loose flange: It consists of flange sleeves, flange glands, sealing gaskets and connecting bolts. It is suitable for occasions where the medium temperature or pressure changes greatly in the pipeline system. It can easily adjust the compression of the sealing gasket to ensure the sealing performance.
The design and use of flanges are directly related to the safety and stability of mechanical systems. It is an annular structure used to connect equipment, pipelines and other components. Fasteners such as bolts and nuts are used to achieve a tight connection between components, thereby ensuring the integrity and efficient operation of the mechanical system. There are many types of flanges. According to their uses, structures and connection methods, they can be divided into many types, such as flat flanges, butt-welded flanges, threaded flanges, loose flanges, etc. Each type has its specific application scenarios and functions.
Flange is an annular part used to connect equipment or components such as pipes, valves, pumps, etc. It is usually equipped with bolt holes, and fasteners such as bolts and nuts are used to achieve a tight connection between components. The existence of flanges plays an important role in ensuring the safety and stability of mechanical systems.
