Metal hose three roles

Metal hose three roles: to reduce piping installation stress, compensating pipe nominal position to absorb the vibration of piping system.1, size hose DN, the choice of the type of connector (mainly flanged, threaded connection, quick connector) and the size of the metal hose, hose lengths. 2, the pressure under actual working pressure hose, corrugated metal hose and then query the nominal diameter and pressure gauges, decide whether to use stainless steel mesh cover types of metal hose. 3, medium hose in the chemical properties of the transmission medium, according Hydraulic tube fittings corrosion resistance of the hose material parameter table, determines the hose material of the parts. 4, the temperature inside the hose and medium operating temperature range; hose when working ambient temperature. High temperatures, the metal hose shall work under high pressure and temperature correction coefficient to determine the temperature corrected pressure to determine the selection of the correct pressure rating. 5, the state is used by the state of the hose, metal hose with reference to the proper use and installation methods and hose compensation in settlement of optimum length. The length of the hose variety of sports state calculation and the minimum number of bends hose and minimum bend radius and other factors, parameters select the correct hose length, and correctly installed.
