Abstract

Apparatus for hydraulic volumetric expansion testing of a gas cylinder 1 by the water jacket or non-water jacket techniques comprises two constant cross-section upright tubes 20, 21, the cross-sectional area of tube 20 being a predetermined fraction of that of the tube 21. The tubes are interconnected by a duct 22 with a shut-off valve 23 and an adjustable overflow device 27,28 is connected to the bottoms of the tubes through a duct 24 having a second shut-off valve 25. A sensor 29 indicates whether water in the larger tube 21 is at or above, or below a predetermined level. For the water jacket technique the larger tube 21 is connected to the water jacket 2 by a duct 30, the apparatus is filled with water to the predetermined level set by the overflow device 27; the shut-off valve 25 is closed and the hydraulic test pressure is applied by a pump 3 to the inside of the cylinder 1, expansion of which expels water from the jacket and raises the water level in both the tubes 20 and 21; the valve 23 is then closed and the test pressure is released from the cylinder which contracts and draws water back into the jacket 2 from the larger tube 21 only, thus lowering the water level in this tube; finally the indication of the sensing device 29 is noted to check whether the water level in the tube 21 is above, or at or below the predetermined level. Since the water volume trapped in the narrow tube 20 represents the permitted permanent volumetric expansion of the cylinder 1, should the water in tube 21 fall to or below the sensor a pass indication will be given for cylinder 1 whereas if the water level fails to fall to the sensor a reject indication is given. <IMAGE>
