Social Benefits: | The equipment comprises of nanostructured magnetostrictive sensing element, typically Fe-Si-B alloy in the form of ribbons which can be easily pasted on the pipe under inspection, An alternating current (50 -100 kHz) for excitation of magnetic field is supplied to the sensing coil in the presence of direct current bias magnetizing field, The element due to magnetostriction generates mechanical waves propagating through the test pipe. The backwall echoes are picked up by the same sensing element and the sensing coil systems, The additional reflected signals indicate the presence of defects in the pipes, Power requirement: 220V, 50Hz |
