Umbhobho wentsimbi emnyama yenziwe ngentsimbi engazange ifakwe i-galvanized.Igama layo livela kwi-scaly, enemibala emnyama ye-iron oxide egqumayo kumphezulu wayo.Isetyenziswa kwizicelo ezingadingi ntsimbi.

Umbhobho wentsimbi emnyama (umbhobho wentsimbi engafakwanga) ubizwa ngokuba “mnyama” ngenxa yesikali esinombala omnyama wentsimbi eyenziwe kumphezulu wawo;idla ngokusetyenziselwa imibhobho yokufudumeza yoxinzelelo oluphantsi lwamanzi ashushu.Ifumaneka kwiishedyuli ezimbini (ishedyuli 40 kunye neshedyuli 80).Umahluko phakathi kweeshedyuli ezimbini ububanzi bodonga lombhobho.IShedyuli ye-80 ipayipi yensimbi emnyama inzima kuneshedyuli 40. Kwiindawo ezininzi ishedyuli ye-80 iyadingeka kumgca we-condensate ngenxa ye-asidi kunye nokungcola.Ndingayicebisa ngamandla kwishedyuli 40.

Xa umbhobho wensimbi wenziwa, i-black oxide scale ifom kumgangatho wayo ukuze inike ukugqitywa okubonakalayo kolu hlobo lombhobho.Ngenxa yokuba intsimbi iphantsi komhlwa kunye nomhlwa, umzi-mveliso ukwawugqume ngeoli yokukhusela.Ezo zinsimbi ezimnyama zisetyenziselwa ukuvelisa umbhobho kunye ityhubhu, engayi kugqwala ixesha elide kwaye idinga ukulungiswa okuncinci.Ithengiswa kwi-TBE eqhelekileyo ye-21-foot ubude.Isetyenziswa ngokubanzi kusetyenziso oluqhelekileyo kumanzi, igesi, umoya kunye nomphunga, imibhobho yentsimbi emnyama kunye netyhubhu isetyenziselwa ukuhanjiswa kwegesi ngaphakathi nangaphandle kwendlu kunye nokujikeleza kwamanzi ashushu kwiinkqubo zebhoyila.Ikwasetyenziselwa imibhobho yomgca kumashishini e-oyile nepetroleum, kwimithombo yamanzi kunye namanzi, igesi kunye neenjongo zogutyulo.
