When selecting the type of gas-liquid booster pump, the pressurization ratio should be calculated according to the target pressure divided by the lowest available gas source pressure, and a safety margin of 20%, 30% should be reserved. For example, for the target 200bar and the lowest 5bar of the gas source, the pressurization ratio should not be lower than 40:1, and the characteristic that the flow rate attenuates with the increase of outlet pressure should be taken into account.

The heat exchange expander can expand the thickness of the tubesheet to 20-120mm, supporting a full-thickness expansion joint and an intermediate tubesheet expansion joint. The working pressure of the equipment is 0-40MPa, the high-pressure machine can reach 100-350MPa, and the pressure control accuracy is ±2%-±3%FS. It is suitable for many kinds of pipes, such as carbon steel, stainless steel, dual-phase steel, titanium alloy, copper pipe and so on.

The pressure range of the pulse test-bed is 0-4.0MPa, 0-30MPa, 0-60MPa, 0-100MPa and other specifications. The equipment adopts pressure closed-loop control, which can accurately reproduce pulse waveforms such as sine, trapezoid and square wave. it is suitable for fatigue testing of pressure-bearing parts such as automobile brake pipe, hydraulic hose, new energy vehicle cooling pipeline and so on.
