Geomembrane Air Pressure Test Gauge plus Needle Air pressure Testing kit for testing HDPE (High Density Polyethylene) geomembrane liner materials, for use on landfill sites, lagoons etc...
The air pressure testing kit consists of:-
Needle – Air Hose – Valve – Manometer - Connector
A brief description of the reason for using this kit is described below:-
Non-Destructive Air Pressure Testing of the test channel on Wedge Welded Joints
The welds are tested for continuity by pressurisation of the central void in the weld. After the weld is completed, the channel is sealed at one end and the other end is attached to the test equipment. The air pressure is applied to the channel. The system is then allowed to stabilise and is isolated from the air pressure source. The air pressure in the channel is then monitored. To establish a satisfactory weld, the air pressure should not change by more than 10% of the initial stabilised value.
