A device for fatigue testing of Teflon hoses comprising a test sample (16) of Teflon hose, first open end of which is clamped to an outlet line of water pump and the 2nd end of which is clamped with a discharge water line (12), forms an interconnecting close loop of water circulation from a tank through a pump via a pressure transmitter and one control valve, tightly coupled to an electromagnetic exciter(6) and one electromagnetic exciter subjects Teflon hose to a predetermined level of vibration for a fixed duration of time and one 50 litre-water tank provided with a water heater, a temperature sensor, a temperature indicator and one inlet and one outlet high pressure and temperature hose pipe are also connected with water tank to circulate high temperature and pressure water into the test loop and one pump (2) along with an attached electrical motor (17) to create high pressure in the testing loop and a pressure gauge and a control valve are also provided in the water flow line and one computer (4) and Industrial Software for data acquisition and the interface communication link between PID Controllers in the control panel; characterized in that the test sample of Teflon hose in the close loop is subjected to circulate hot and pressurized saline water and a predetermined level of vibration from the electromagnetic exciter coupled with said hose for a fixed duration of time extending to tens of hours to check and detection of any leakage of the Teflon hose wherein pressure and temperature information/data are continuously acquired electronically, stored and displayed in the form of graphical plots on CRT screen of the device.
