Hydrostatic Pressure Testing Services

1. Hydrostatic Pressure Testing

The hydrostatic pressure testing rig is designed to hydrostatic test cylinders and other devices whilst also reading the volumetric expansion of the cylinder.

If Quality Assured certification is required we are able to data log the test and print out the hydrostatic test results. (view crystal digital test gauges below)

The rig is capable of testing up to 100,000kpa / 14,500psi / 1,000bar.

Crystal Digital Test Gauges

Do you require high accuracy with you’re testing requirements?
We have invested in Crystal Digital Test Gauges.
This allows us to work to extremely high accuracy in relation to achieving pressure test results.
In addition if you require proof of the test for Quality Assurance requirements,
The Crystal Digital Test Gauges allows us to Data Log into the gauge to print out test reports.

2. Air Testing Apparatus

The air testing rig has been designed to test with pure breathable air as the test medium. Occasionally we are asked to proof test or leak test devices with a medium that contains no fluids or moisture. This apparatus is capable of tests up to 4,000kpa / 580psi / 40bar.
If requested under strictly controlled conditions, at our discretion we may carry out tests up to
40,000kpa / 5,800psi / 400bar.

3. Low Pressure Testing Pumps

Fire System Services has several low-pressure test pumps. These low-pressure test pumps are fully portable and versatile, making them ideal for Hydrostatically testing cylinders both in the workshop and in the field. These pumps are capable of testing up to 3,000kpa / 430psi / 30bar.

4. Custom Testing Services

Apart from cylinders, the station is called upon to hydrostatically test & certify various items such as:

Hydraulic lines for the aviation industry ie Helicopter Hydraulic Lines
Prototype devices designed & manufactured by the DSTO (Weapons Research Division)
Devices in use by Department of Defence
Various high-pressure hoses for fire fighting applications
SCUBA & Hooker air lines
Scientific Pressure Vessels
