Hydraulic presses hydraulic piping has a high working pressure,sensitive to fluid cleanliness,piping specifications,complex systems and other characteristics.Traditional hydraulic pipeline connection using welding,welding pipeline need X-ray flaw inspection,pickling,phosphating,and finally using hydraulic oil flushing to ensure the quality of the welded pipeline and internal cleanliness.The construction process is more complicated.In this paper,through the analysis of the principle and structure of non-welded piping system,the application of non-welded piping system of hydraulic machine is discussed.Practice has proved:non-welded piping system technology process is simple,pollution and leakage is easy to control,the application of the promotion in the hydraulic machine has obvious advantages,has a wide range of application prospects.
