A pipe joint is a connecting tool between pipelines, which is a detachable connection point between components and pipelines. It plays an indispensable role in fittings and is one of the two main components of hydraulic pipelines. Pipe joints are used for straight connections such as instruments, and the connection forms include socket welding or threaded connections. Mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or as the final adjustment for pipelines using threaded fittings. The structural form should adopt a metal surface contact sealing structure, and the gasket sealing structure is usually used for conveying general pipelines such as water, oil, and air, and is made of malleable cast iron material. In addition, usage requirements and price are also factors considered when selecting.
There are various types of pipe joints, and commonly used pipe joints can generally be divided into two types: hard pipe joints and flexible pipe joints. If classified according to the connection method of pipe joints and pipelines, there are three types of hard pipe joints: expansion type, sleeve type, and welding type, while hose joints are mainly compression type hose joints
