Fittings are crucial detachable components in pipe systems, consisting of a pair of flanges, a sealing gasket, and bolts and nuts. Their core function is to facilitate the convenient connection between pipes and between pipes and equipment, while ensuring the sealing and pressure resistance of the interface. They can be categorized by their connection method, such as flat welding flanges and socket welding flanges, and by their sealing face form, such as flat and raised faces. Selection depends on the medium pressure and properties. In steel pipe connections, flanges are fixed to the steel pipe through welding or threaded connections, with the gasket sandwiched between the two flanges. Tightening the bolts forms a seal. They are widely used in the petrochemical, water supply and drainage, and power industries, particularly suitable for pipe joints that require frequent disassembly and maintenance. They are an indispensable basic component in pipeline engineering.

Flanges are commonly used detachable components in pipeline connections, consisting of a pair of flanges, gaskets, and bolts/nuts. They are used to connect pipes to pipes, and pipes to equipment. Their core function is to facilitate pipeline installation, disassembly, and maintenance while ensuring the sealing and pressure resistance of the connection points. Flanges can be classified by their connection methods, such as flat weld flanges, socket weld flanges, and slip-on flanges, and by their sealing face shapes, including flat, raised, and concave-convex surfaces. They need to be selected based on pipeline pressure, medium properties, and installation requirements. In steel pipe systems, flanges are connected to steel pipes through welding or threaded connections, with the gasket placed between the sealing faces of the two flanges. After tightening the bolts, a seal is formed. They are widely used in the petrochemical, water supply and drainage, power, metallurgy, and other fields, especially suitable for pipeline joints that require frequent disassembly or maintenance.
