Tswv yim rau Corrosion Detection ntawm Shipbuilding Steel Phaj ASTM A131 Marine Steel rau Nkoj

Nyob rau hauv kev lag luam marine, kev txhim khu kev qha ntawm corrosion nyob rau hauv ASTM A131 Shipbuilding Steel Phaj Marine Steel yog qhov tseem ceeb tshaj plaws los xyuas kom meej tias muaj kev nyab xeeb thiab ntev ntawm cov hlab ntsha. Cia peb tshawb nrhiav ntau qhov xwm txheej uas qhia txog cov kev ua tau zoo thiab cov txiaj ntsig hauv qhov tseem ceeb no.

Ib qho xwm txheej tseem ceeb cuam tshuam nrog lub nkoj thauj khoom loj uas tau ua haujlwm tau ntau xyoo. Txhawm rau ntsuas qhov corrosion ntawm nws lub nkoj, kev tshuaj xyuas zoo tau ua tiav. Kev kuaj pom pom tau pib ua, nthuav tawm thaj chaw ntawm xeb thiab tawg. Txawm li cas los xij, kom tau txais kev nkag siab tob txog qhov kev txhim kho corrosion, electrochemical impedance spectroscopy (EIS) tau ua haujlwm. Cov txheej txheem no tau muab kev nkag siab zoo rau kev tiv thaiv cov khoom ntawm cov txheej txheem thiab cov hauv qab steel qhov kev tiv thaiv corrosion. Cov txiaj ntsig tau qhia cov cheeb tsam hauv cheeb tsam ntawm kev cuam tshuam cov txheej txheem thiab cov cim ntxov ntawm corrosion hauv qab. Raws li cov kev tshawb pom no, lub hom phiaj kev saib xyuas thiab kho cov txheej txheem tau ua tiav, tiv thaiv kev puas tsuaj ntxiv thiab txuas ntxiv lub nkoj ua haujlwm.

Hauv lwm qhov piv txwv, lub nkoj ntawm cov roj tankers tau raug soj ntsuam xyuas corrosion tsis tu ncua. Ultrasonic kuaj tau siv los kuaj xyuas sab hauv corrosion thiab thinning ntawm cov hlau phaj hauv cov khoom thauj. Los ntawm kev xa cov ultrasonic nthwv dej los ntawm cov hlau thiab tshuaj xyuas cov echoes, cov kev ntsuas meej ntawm cov hlau poob tau txais. Qhov no tau tso cai rau kev teem sijhawm ua haujlwm ntawm kev saib xyuas thiab hloov cov phiaj xwm hnyav, txo qhov kev pheej hmoo ntawm kev xau thiab ua kom muaj kev nyab xeeb ntawm kev thauj khoom txaus ntshai.

Lub nkoj caij nkoj tau dhau los ua qhov tseem ceeb, thiab thaum lub sijhawm ua haujlwm no, kev ntsuas corrosion ntawm lub lawj thiab superstructure yog qhov tseem ceeb. Kev sib xyaw ua ke ntawm kev kuaj hluav taws xob thiab tshuaj ntsuam xyuas cov khoom siv corrosion tau ua haujlwm. Cov duab hluav taws xob tau nthuav tawm zais cov kab nrib pleb thiab cov voids uas tshwm sim hauv cov tswv cuab ntawm cov qauv, thaum tshuaj ntsuam xyuas tau pab txheeb xyuas cov kab mob corrosive thiab lawv qhov chaw. Qhov kev qhia dav dav no tau ua rau kev siv cov tswv yim tiv thaiv kev tiv thaiv zoo thaum lub sij hawm refit, txhim kho lub nkoj kev zoo nkauj thiab kev ncaj ncees ntawm cov qauv.
