Ikhoyili yentsimbi yesinyithi:umtshintshi wobushushu, ibhoyila, i-petroleum, ikhemikhali, isichumisi sekhemikhali, ifayibha yemichiza, amayeza, amandla enyukliya, njl.
Ikhoyili yentsimbi engatyiwayo yolwelo:isiselo, ibhiya, ubisi, inkqubo yokubonelela ngamanzi, izixhobo zonyango, njl.
Ikhoyili yensimbi engenasici kwisakhiwo soomatshini:ukuprinta kunye nokudaya, ukuprinta, oomatshini belaphu, izixhobo zonyango, izixhobo zasekhitshini, iimoto kunye neenxalenye zeenqanawa, ukwakhiwa kunye nokuhombisa, njl.
Ikhoyili yentsimbi eqaqambileyo:ibhanti yensimbi engenasici idityanisiwe kwaye emva koko udonga luyancipha. Udonga luyancitshiswa ukusuka kwingqimba ukuya kwincinci. Le nkqubo inokwenza ubuninzi bodonga bufanane kwaye bugudiswe, kwaye udonga luyancitshiswa kwaye lunwenwe ukwenza umphumo wokungabikho kwe-weld. Ngokutsho iliso umbhobho ingenamthungo, kodwa inkqubo yayo isigqibo umbhobho welded. INKQUBO yokunciphisa udonga ihamba kunye ne-annealing eqaqambileyo, ukwenzela ukuba udonga lwangaphakathi nangaphandle aluyi kwenza i-oxide layer, kwaye ingaphakathi nangaphandle elikhanyayo kunye nenhle, efunekayo ngokwenene kwiimveliso zonyango. Inkqubo elandelayo idinga ubungakanani, oko kukuthi, inkqubo encinci yokutsalwa, ukumisela i-diameter yangaphandle, unyamezelo lwedayamitha yangaphandle inokufikelela ngokubanzi okanye thabatha i-0.01mm.
