Nyob rau hauv ib qho qhib dej system a corrosion tus nqi ntawm ib ncig ntawm 1 MPY yog qhov qub. Muaj corrosion tus nqi ntawm ib ncig ntawm 10, koj yuav tsum tau nqis tes ua. Corrosion tus nqi ntawm 20 MPY thiab siab dua, koj yuav tsum txhawj xeeb, raws li qhov corrosion yog "noj" hlau ceev ceev.

Ib yam li ntawd, koj tuaj yeem nug, tus nqi corrosion yog dab tsi?

Corrosion tus nqi yog qhov ceev ntawm cov hlau hauv ib puag ncig tshwj xeeb deteriorates. Nws kuj tuaj yeem txhais tau tias yog tus nqi ntawm corrosion poob ib xyoo nyob rau hauv thickness. Qhov ceev los yog tus nqi ntawm deterioration nyob ntawm ib puag ncig tej yam kev mob thiab hom thiab mob ntawm cov hlau raws li siv.

Ib tug kuj yuav nug, dab tsi yog qhov corrosion ntawm steel? Cov corrosion tus nqi ntawm steel nyob rau hauv cov av muaj peev xwm nyob ntawm tsawg tshaj li 0.2 microns ib xyoo nyob rau hauv tej yam kev mob rau 20 microns ib xyoo los yog ntau tshaj nyob rau hauv heev txhoj puab heev av.

Ib yam li ntawd, tib neeg nug, ua li cas koj suav tus nqi corrosion?

Txhawm rau xam tus nqi ntawm corrosion, cov ntaub ntawv hauv qab no yuav tsum tau sau:

  1. Poob qhov hnyav (qhov txo qis hauv qhov hnyav hlau thaum lub sijhawm siv sijhawm)
  2. Density (qhov ntom ntawm cov hlau)
  3. Cheeb Tsam (tag nrho thawj qhov chaw ntawm daim hlau)
  4. Sijhawm (qhov ntev ntawm lub sijhawm siv sijhawm)

MPY sawv rau dab tsi hauv corrosion?
