Product Description

 SY-05 Hydrostatic Test Machine is used for water jacket method hydrostatic testing for the different kinds of gas cylinders that require volumetric expansion testing during their manufacturing, inspection and evaluation. The test machine is designed and manufactured according to GB/T9251-1997 Hydrostatic Testing Method for Gas Cylinderand American DOT standard.


The test machine is suitable for cylinders as below:


Capacity: From 57L to 130L; Length: from 90cm to 200cm


Diameter: from 110mm to 410mm


 Key features and advantages:

  1. Control mode: PC control
  2. Software specification and display ((include: pressure rate, pressure drop detection, test time, save data for each cylinder, P-T diagram for each cylinder from beginning to end of the test).
  3. Real-time monitoring as well as data recorded on high-speed sampling cards and also testing curves printing
  4. Alarming at due time bursting and due point recording

       5. Computer software on American LABVIEW

       6. Material of water jacket: common carbon steel


 The design pressure of the test machine is 50Mpa; the testing pressure   accuracy is no less than 10 Psi, and the water level measuring accuracy is no less than 0.1g. Time-pressure testing curve, time-water versus pressure-water testing curve can be displayed dynamically in graphics mode during testing.


All testing data will be saved in the computer, and the user can query all the testing data and testing curves for all the tested cylinders from the computer according to requirements.


        Main technical parameter:

  1. Pump model: GD100 pump

    Max. working pressure: 80Mpa

    Electronic balance: 0-1500g (accuracy 0.1g)

    Pressure sensor: 0-100Mpa (accuracy 0.1g)

    Test pressure: 50Mpa

    Work power:  AC220V/50HZ

    Control mode:  PC Control (automatic control)

    Applicable medium: Water

    Quantity of cylinders per shift for test:  40 per 8 hours


     Working principle:

    Water jacket method is applicable to all hydrostatic tests where determination of volumetric expansions is required. It consists of enclosing a cylinder filled with water inside a test jacket filled with water. Pressure is then applied internally to the cylinder, causing the cylinder to expand. The total and permanent volumetric expansions of the cylinder are determined by measuring the amount of water displaced by the expansion of the cylinder when under pressure and after the pressure has been released. This is the only testing method that will requalify a cylinder for charging to 10% in excess of the marked service pressure.


    Put the cylinder into a water jacket through hoist device and pressurize the cylinder by the hydrostatic test machine; it will automatically dwell at a set pressure and do pressure testing on the cylinder. At the same time, the cylinder volume expands under pressure and squeezes some water from water jacket into the measuring cup(burette), and then the water is transferred to PC by water collection system(water tank); the cylinder elastic deformation disappears after pressure releasing, then some water flows back from measuring cup to water jacket. However, the remaining water in the measuring cup is still more than that before pressurizing the cylinder. And extra amount of water (when pressure has been released) in the measuring cup is the permanent volumetric expansion of the cylinder; the extra amount of water (attaining test pressure) in the measuring cup is the total volumetric expansion of the cylinder. And the permanent volumetric expansion rate is the ratio of permanent volumetric expansion to total volumetric expansion.

    Permanent volumetric expansion, total volumetric expansion and permanent volumetric expansion rate etc will be displayed in the computer software.
