Leak Testing Methods

There are many different methods for pressure and leak testing in the field. Seven of these are:...

X ray inspection---Film and intensifying screen

The film system is divided into four categories according to GB/T19384.1, namely T1, T2, T3, T4. T1 is the highest category and T4 is the lowest category....

Pressure Testing

Pressure Testing is a non-destructive test performed to ensure the integrity of the pressure shell on new pressure equipment...

X-ray inspection process---boiler manufacturing(1)

When the thickness of the hood is different for steel pressure equipment, the maximum allowable pipe voltage should be controlled within the specified range....

History of Eddy Current Testing

The phenomenon of eddy currents was discovered by French physicist Léon Foucault in 1851, and for this reason eddy currents are sometimes called Foucault currents....

Eddy Current

Eddy current array (ECA) is a nondestructive testing technology that provides the ability to electronically drive multiple eddy current coils, which are placed side by side in the same probe assembly. ...

Eddy current testing - material inspection

Conductivity measurement uses eddy current conductivity meter to measure the conductivity value of non-ferromagnetic metal....

Non-destructive testing---Eddy current testing

The batch pipe generally adopts the eddy current automatic flaw detection device, which can automatically alarm, automatically record, automatically sort and automatically stop....

Positive Material Identification

Today, many major oil companies require that every pipe, flange, connector, valve and welding seam in critical parts of the plant be measured to verify that materials match engineering specifications....

Non-destructive testing---Signal detection circuit

Under normal circumstances, the balance of the bridge circuit can be achieved by adjusting the variable resistor in the balanced bridge, as shown in the following figure:...
