Hydrostatic Pressure Test and Spark Test


A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing and gas cylinder tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. All the accessories required for test will be provided by us including valves, blind flanges, gaskets and pressure gauge.

The spark testing of a conductive geomembrane typically utilizes a high voltage spark tester – typically those over 5KV – These operate by generating a narrow pulse of high voltage. These pulses occur between 30 and 150 times per second and any holes in the material being tested will allow this high voltage to arc across to the ground side of the circuit. This current flow is detected and indicated (by visual and audible signals typically).
