Nitrogen Pressure Test and Purge Practicals
Trainees braze a copper joint while a slow flow of nitrogen passes through the pipe, set on the Nitrogen Flow Regulator Meter For Brazing. They use copper-phosphorus Brazing Rod for the copper-to-copper joint. Cutting the joint open afterwards shows a clean bore, while a joint brazed without purge is black with oxide scale inside.
For a pressure test, the cylinder feeds the Nitrogen Pressure Test Kit, whose regulator brings the pressure down to the test level. Students pressurise a finished line set, note the gauge reading, and check it again later to see if it holds.
Frequently Asked Questions
Why use nitrogen and not oxygen or air?
Nitrogen is inert and dry. It will not burn, it does not react with oil, and it adds no moisture to the system. Oxygen can ignite violently with oil under pressure, and compressed air brings water vapour in.
Can the cylinder be connected straight to a system?
No. Cylinder pressure is far higher than any refrigeration system is built for. Always fit a nitrogen regulator, set the outlet pressure, and only then open the valve to the pipework.
What does water capacity mean?
It is the internal volume of the cylinder, measured as the water it would hold, here 8 litre. The amount of nitrogen inside depends on the fill pressure marked on the cylinder.
How does this differ from the 50 litre cylinder?
Both supply nitrogen for testing and purging. This 8 litre aluminium cylinder is the compact choice for a service kit or a lab bench. The 50 litre one holds far more gas for a busy workshop.
How should it be stored and moved?
Keep the safety cap on whenever no regulator is fitted. Move the cylinder on its trolley and store it upright and secured in a cool, ventilated place.
