Product Features: Welded pipe joints is a hydraulic fluid power and general use equipment piping systems essential parts. In a hydraulic system, energy from the hydraulic oil through the hydraulic connections and that the tube hose system for delivery. If you put a hydraulic pump compared to a person's heart , then hydraulic tubing is connected vessels ; modern industry requires increasingly higher hydraulic system operating pressure . High-speed operation of hydraulic equipment requirements of hydraulic systems can withstand high voltage pulse , requires Welded pipe joints in the system must withstand higher pressure peaks and vibration energy to guarantee the normal transport . Its failure will cause the pipeline leak ,hydraulic hose and fittings  a serious cause of pipeline rupture. The first oil pipeline environmental laws and regulations is not allowed. More importantly , the modern large-scale mechanized production equipment shall continue to operate in order to ensure production efficiency , basically does not allow non-normal downtime ; General hydraulic oil for Welded pipe joints is not corrosive , so the hydraulic system commonly used carbon steel welded pipe joints , drinking water or purified water should not be used to connect pipes carbon steel welded pipe joints .
        The traditional brass welded joints using compressed air series , because the compressed air carries moisture build-up inside the tube will corrode if welded joints . Chemical equipment, piping conveying a variety of corrosive fluids usually requires frequent washing with solvent or water , so the general chemical piping must be stainless steel . Welded joints in hydraulic systems have different functions : the high pressure , low pressure return line and suction line . Accompanied by high pressure pipeline strong impact and high turbulence , to ensure the seal in this condition . Suction line liquid flow rate is low , in order to ensure the pumps are not subject to cavitation damage , you must select the appropriate connector , hydraulic hose adapters ensure piping exposed to vacuum and to minimize pressure loss. Select welded joints should know nominal pressure hydraulic pipe fittings . PN is a standard parameter and the system is numerically equal to the maximum working pressure .
