Pipeline siam chhuah hi professional zawka siam theih nan test thenkhat kan nei tlangpui a, chuti a nih chuan Eddy current flaw detection test hi eng nge ni?
Eddy-current testing (Eddy current testing leh ECT anga ngaih tlangpui) hi nondestructive testing (NDT)-a hman thin electromagnetic testing method tam tak zinga pakhat a ni a, conductive material-a surface leh sub-surface flaws te hriat leh characterize nan electromagnetic induction hman a ni.
Eddy current detection hman dan tlangpui chu heat exchanger leh condenser-a pipeline check te a ni.
ECT hian electromagnetic induction hmangin pipeline-a chhiatna awmte chu a hriat theih a ni. Probe chu tube chhungah dah la, tube chhungah chuan kal rawh. Eddy currents te hi probe chhunga electromagnetic coil atanga siam a ni a, a rualin probe electrical impedance tehin a enkawl a ni ..
Eddy current tube detection hi pipe defect hmuhna atana hman tlak loh, pipe material hrang hrang tam tak tan a tangkai a, heat exchanger leh condenser-te tana harsatna lian zawk thlen thei defect a hmuchhuak thei a ni.
Eddy current detection method hmangin pipe chhunga defect chi hrang hrang hmuhchhuah theih a ni:
1.Internal diameter (ID) leh pawn lam diameter (OD) pitting .
2.Cracking .
3.Wear (supporting structures, pipe dang leh loose parts atanga lo chhuak)
4. Pawn lam diameter leh a chhung lam diameter erosion .
