It plays an indispensable and important role in pipe fittings, and it is one of the two main components of hydraulic pipelines. Pipe joints are used for straight-line connections such as instruments, and the connection forms include socket welding or threaded connections. It is mainly used for small-diameter low-pressure pipelines, used for parts that need to be assembled and disassembled frequently, or used for final adjustment of pipelines using threaded pipe fittings. The structural form should adopt the metal surface contact sealing structure, and the structural form of the gasket seal is usually used in general pipelines such as water, oil, and air. There are many types of pipe joints. Commonly used pipe joints can generally be divided into two types: hard pipe joints and hose joints. According to the connection method of pipe joints and pipes, there are three types of hard pipe joints: flare type, ferrule type and welding type. Applicable media for flared pipe joints: oil, water, gas and other non-corrosive or corrosive medium pipe joints. The specification requirements for matching steel pipes are relatively flexible. After welding with pipes, they have the characteristics of firm connection and good sealing performance. Therefore, in It is widely used in oil refining, chemical industry, light industry, textile, national defense, metallurgy, aviation, shipbuilding and other systems; it is also suitable for hydraulic transmission lines such as various mechanical engineering and machine tool equipment.
