Insimbi yokushisisa kagesi engagqwali (ithubhu yokushisisa kagesi) iyishubhu lensimbi njengegobolondo, kanye nezintambo zikagesi ezivunguzayo zengxubevange (nickel-chromium, iron-chromium alloy) zisatshalaliswa ngokufanayo ku-eksisi emaphakathi yeshubhu. Izikhala zigcwaliswa futhi zihlanganiswe ne-magnesium oxide powder ene-insulation enhle kanye ne-thermal conductivity. Zombili iziphetho zivaliwe ngejeli ye-silica noma i-ceramics. Lesi sici sokushisa sikagesi esine-armored singasetshenziswa kabanzi ukushisisa amanzi, uwoyela, umoya, isixazululo se-nitrate, isisombululo se-asidi, isixazululo se-alkali nezinsimbi ezincibilikayo eziphansi (i-aluminium, i-zinc, ithini, i-babbitt alloy) , Inezinzuzo zokusebenza kahle kokushisa. , izinga lokushisa elifanayo, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, nokusebenza kahle kokuphepha.
