CNC Pipe Joint Components, Types, Structure - CNC Machined Auto  Components Pipe Joint

Pipe joint, is a connecting tool between pipeline and pipeline, and it is a disassembly connection point between components and pipeline. It plays an indispensable and important role in pipe fittings. It is one of the two main components of hydraulic pipeline.

CNC automotive components pipe joints are used for straight-line connection of instruments, in the form of socket welding or threaded connection. Mainly used for small caliber low-pressure pipelines, for parts requiring frequent assembly and disassembly, or for final adjustment of pipelines using threaded fittings. The structure of gasket seal is usually used for conveying water, oil, air and other general pipelines. It is made of malleable cast iron.

There are many types of pipe joints. The commonly used CNC pipe joints automotive parts can be divided into hard pipe joints and hose joints. If according to the connection mode of pipe joints and pipes, there are three types of hard pipe joints: expansion type, welding type and clamp type. Hose joints are mainly buckled hose joints.

CNC Machined Pipe Joint Material Compatibility

The material used for Dajin Precision CNC pipe joint is mechanically and chemically compatible with the pipe transporting the fluid. If welding is required, then the two materials must also be chemically compatible to effect a correct weld.

Further, the material of construction of the joint must have very close corrosion-resistant characteristics to the parent pipe, for the fluid transported internally and the external environment. For use in food and drug industries, the jointing material must not contaminate the process fluid.

Materials of different chemical compositions can be welded together as long as there is no possibility of galvanic corrosion, the correct weld procedure is in place, and the weld is executed by a suitably qualified technician.
