Txias-tsim steel, vim nws muaj ntau hom ntoo khaub lig- ntu cov duab, lub teeb yuag, lub zog siab, thiab kev ua haujlwm yooj yim, yog siv dav hauv cov tsev steel qauv, cov chaw khaws khoom, cov khoom siv txuas ntxiv, thiab cov txheej txheem kev txhawb nqa ib ntus.Txawm li cas los xij, nws qhov chaw muaj kev cuam tshuam rau corrosion, deformation, los yog xoob ntawm kev sib txuas. Yog tias tsis muaj kev saib xyuas zoo, kev ua haujlwm ntawm cov txheej txheem yuav tsis muaj zog thiab kev pabcuam lub neej luv. Tsim kom muaj kev tswj xyuas kev tshawb fawb thiab tsim nyog yog ib qho tseem ceeb los xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm txias - ua hlau.
Kev tu yuav tsum pib nrog kev tshuaj xyuas txhua hnub. Cov tsos mob ntawm cov khaub thuas- tsim cov khoom siv hlau yuav tsum tau tshuaj xyuas tsis tu ncua, tsom rau kev ncaj ncees ntawm cov txheej txheej saum npoo av, xeb ntawm cov welds thiab txiav npoo, thiab seb cov kab txuas puas yog xoob lossis hloov chaw. In humid, salt spray, or chemically corrosive environments, the frequency of inspections should be appropriately increased to promptly detect localized rust spots, blistering, or coating peeling, and take measures to prevent corrosion spread. Cov ntaub ntawv tshuaj ntsuam xyuas yuav tsum tau nthuav dav, tsim cov ntaub ntawv traceable los muab lub hauv paus rau kev saib xyuas tom ntej.
Kev ntxuav yog lub hauv paus ntawm kev saib xyuas. Txoj kev ntxuav kom tsim nyog yuav tsum raug xaiv raws li hom kev sib kis. Cov plua plav zoo tib yam tuaj yeem raug tshem tawm los ntawm qhov qis - tso dej los yog txhuam muag muag. Roj stains los yog adhering tshuaj yuav tsum tau siv ib tug nruab nrab detergent ua ke nrog txhua yam wiping kom tsis txhob ua puas lub txheej tiv thaiv. Kev saib xyuas tshwj xeeb yuav tsum tau them rau tshem tawm cov seem weld slag thiab impurities los ntawm cov chaw welded thiab txiav, vim tias cov cheeb tsam no nquag ua cov ntsiab lus pib corrosion. Tom qab ntxuav, qhov saum npoo yuav tsum qhuav tag ua ntej siv kev tiv thaiv kev tiv thaiv kom tsis txhob ya raws los ntawm kev ua kom corrosion.
Kev tiv thaiv corrosion yog ib qho tseem ceeb ntawm kev txias txias -tsim steel txij nkawm. Rau kub-dip galvanized lossis lwm yam hlau-coated Cheebtsam, qhov txuas ntxiv ntawm txheej yuav tsum tau kuaj xyuas. Txhua qhov kev puas tsuaj yuav tsum tau kho tam sim ntawd nrog cov tshuaj tiv thaiv- xeb lossis cov khoom siv hauv zos. Rau ungalvanized liab qab steel nto, anti- xeb primer thiab topcoat yuav tsum tau siv tsis tu ncua, xyuas kom meej lub thickness thiab adhesion raws li specifications. Nyob rau hauv dej hiav txwv los yog siab -cov av noo ib puag ncig, kev tiv thaiv cathodic tuaj yeem sib xyaw ua ke, siv cov anodes txia lossis kev qhuas tam sim no kom qeeb cov txheej txheem electrochemical corrosion.
Kev saib xyuas cov qauv thiab cov khoom sib txuas yog qhov tseem ceeb sib npaug. Lub torque nruj ntawm bolted kev sib txuas yuav tsum tau xyuas tsis tu ncua. Loosening yuav tsum tau kho kom sai, thiab cov fasteners hnyav hnyav yuav tsum tau hloov yog tias tsim nyog. Welded pob qij txha yuav tsum tau soj ntsuam rau cov kab nrib pleb, tshwj xeeb tshaj yog cov khoom nyob rau hauv dynamic loads los yog nyob rau hauv ib puag ncig kev co, thiab cov zaus soj ntsuam yuav tsum tau nce. Hauv zos deformation tshwm sim los ntawm kev cuam tshuam sab nraud lossis kev hloov pauv yuav tsum raug kho lossis hloov cov khoom cuam tshuam los kho qhov qub kev ntxhov siab.
Txias- cov seem steel uas tsis ua haujlwm raws caij nyoog lossis tsis ua haujlwm rau lub sijhawm ntev yuav tsum tau tiv thaiv nrog kev ntsuas xws li cov dej ntws tawm, npog nrog cov dej noo- cov ntaub ntawv pov thawj, lossis nitrogen purging kom txo tau qhov kev pheej hmoo ntawm ib puag ncig corrosion. Ua ntej rov pib dua, yuav tsum muaj kev tshuaj xyuas dav dav thiab kev ntsuas kev ua haujlwm tsim nyog kom ntseeg tau tias tsis muaj teeb meem zais ua ntej muab tso rau hauv kev siv.
Feem ntau, kev saib xyuas ntawm qhov txias- cov seem steel yuav tsum ua raws li lub hauv paus ntsiab lus ntawm kev tiv thaiv ua ntej, ua ke nrog kev tswj xyuas. Lub kaw - lub voj kev tswj xyuas yuav tsum tau tsim los ntawm kev tshuaj xyuas txhua hnub, ntxuav thiab tshem tawm, tiv thaiv corrosion thiab kho, thiab kev sib txuas. Kev ua raws li kev tswj hwm nruj me ntsis tuaj yeem tsis tsuas yog tswj xyuas qhov zoo ntawm cov qauv thiab kev ua haujlwm zoo, tab sis kuj tseem txuas ntxiv nws lub neej kev pab cuam, txo cov nqi khiav lag luam, thiab muab kev lav zoo rau qhov project kev nyab xeeb thiab cov txiaj ntsig kev lag luam.
