Dab tsi yog qhov tsis xws luag hauv cov hlab ntsha siab?

1. Corrosion
Cov tsos mob: thinning, los yog sib xyaw ua xeb ntawm sab hauv lossis sab nraud vim yog xov xwm (xws li cov kua qaub, alkali, noo noo) lossis ib puag ncig cov teebmeem.
Cov phom sij: Cov Phab Ntsa Cov Hluav Taws Xob tsis txaus ntseeg yuav ua rau txo qis zog lossis txawm tias tawg.
Kev Kawm Txog Kev Kawm: Ua tsis tiav sai sai sab hauv phab ntsa corrosion hauv ib lub taub ntim cia ua rau muaj kev kub ntxhov.
2. Cov kab nrib pleb
Hom: Kev ntxhov siab corrosion cracking, qaug zog tawg, weld cracking, thiab lwm yam.
Cov phom sij: cov lus tshaj tawm tsis tuaj yeem ua rau tawg, tawg, lossis xau dej.
Kev Kawm Kev Kawm: Cov kab nrib pleb hauv P91 / P92 Hlau Weld vim kev ua haujlwm tsis xws luag hais tias thaum lub sijhawm ua haujlwm, ua rau lub cev tsis ua hauj lwm.
3. Deformation thiab bulging
Cov tsos mob: dentsized dents, kev thab plaub, lossis tag nrho kev deformation.
Cov ua rau: kev nyuaj siab, thermal kev ntxhov siab, lossis kev puas tshuab kev puas tsuaj.
Qhov phom sij: Cov txheej txheem ruaj khov, muaj peev xwm ua rau cas ua cascading ua tsis tiav . 4. vuam tsis xws luag
Cov teeb meem tshwm sim: Tsis muaj Fusion, Porosity, Sluag suav, misalignment, thiab lwm yam.
Kev pheej hmoo: Tsis muaj weld muaj zog, ib qho chaw ntawm cov kab nrib pleb.
5. Tsis ua haujlwm ntawm kev nyab xeeb cheeb tsam
Xws li: uncalibrated lossis ploj lawm kev nyab xeeb li qub, tawg discs, lossis siab gauges.
Tej yam yuav tshwm sim: Tsis muaj peev xwm tso kev tsis ncaj ncees, ua rau tawg.
6. Khoom siv tsis haum
Cov tsos mob: cov laus laus thiab hloov pauv hauv cov duab hlau (xws li graphitization).
Kev cuam tshuam: txo lub zog thiab tawv tawv, nquag mus rau brittle backstre.
