Closed pressure vessels are used to determine the ballistic properties of explosive materials.
They are designed up to maximum working pressure of 500 MPa (5000 bar) and are available with a chamber volume of 25 to 700 ccm.
Each vessel is tested at a static pressure of 600 MPa. The L/D ratio of the combustion chamber is constant for all types of pressure vessel at 2:1.
The improved pressure vessels are designed to meet the needs of practicable work.
Components subject to wear and tear can be quickly and easily replaced and they are cheap
