Ngokutsho kwetafile yesinyithi, ipropathi esebenzayo yobhedu yensimbi iphantsi, ngoko ke ukuxhatshazwa kwe-corrosion kungcono kunezinye isinyithi.Ipropathi yeekhemikhali zobhedu obomvu izinzile, idibanisa ukumelana nokubanda, ukumelana nobushushu, ukunyanzeliswa koxinzelelo, ukunyanzeliswa kwe-corrosion kunye nokumelana nomlilo (indawo yokuncibilika kobhedu iphezulu njenge-1083 degrees Celsius).Ngoko ke, iplagi ephezulu ebomvu yobhedu ihlala ihlala kwaye ingasetyenziselwa kwiindawo ezahlukeneyo ixesha elide.
