What is a Pneumatic Test? (with pictures)
What is a Pneumatic Test? (with pictures)

19/1/2021, · A tire pressure gauge is used to test the, pneumatic pressure, in a tire. A pressure, test, verifies the pressure capacity or tests the current pressure of a system. A, pneumatic test, is one type of pressure, test,. Common pneumatic measurement test equipment includes gauges that read pressure and a source of compressed gases.

Pneumatic testing is often used to test piping systems when the presence of moisture is undesirable or removal of residual water cannot be conveniently achieved. Due to incompressibe nature of hydrotest fluid, the energy stored in a piping system under hydrostatic pressure is far less in comparison to a piping system which is subjected to pneumatic pressure.
