Iityhubhu zentsimbi ezingenamthungoZininzi kakhulu.Iityhubhu zentsimbi ezingenamthungo zenjongo ngokubanzi ziqengqeleka ukusuka kwintsimbi yolwakhiwo lwekhabhoni eqhelekileyo, intsimbi yolwakhiwo lwealloyi ephantsi okanye ialloy structural steel, enemveliso enkulu, kwaye isetyenziswa ikakhulu njengemibhobho okanye iindawo zolwakhiwo zokuthutha ulwelo.

Ngokweendlela ezahlukeneyo zokusetyenziswa, zihlulwe zibe ngamacandelo amathathu:

a.Ukubonelela ngokubunjwa kweekhemikhali kunye neempawu zoomatshini;

b.Ubonelelo ngokweempawu zoomatshini;

c.Nikeza ngokovavanyo lwe-hydraulic.Kwimibhobho yentsimbi enikezelwe ngokutsho

kwiindidi u-a kunye no-b, ukuba zisetyenziselwa ukumelana noxinzelelo lwamanzi, iimvavanyo ze-hydraulic nazo ziyafuneka.

Imibhobho ekhethekileyo engenamthungo ibandakanya imibhobho yebhoyila engenamthungo, amandla ekhemikhali, imibhobho engenamthungo yejoloji kunye nemibhobho engenamthungo yepetroleum.

Imibhobho yentsimbi engenamthungo engenamthungo inecandelo elinqamlezileyo kwaye isetyenziswa ngokubanzi njengemibhobho yokuthutha ulwelo, njengemibhobho ethutha ioli, igesi yendalo, igesi, amanzi, kunye nezinto ezithile eziqinileyo.Xa kuthelekiswa nentsimbi eqinileyo efana nentsimbi engqukuva, umbhobho wentsimbi ukhaphukhaphu ngobunzima xa unamandla afanayo aguquguqukayo kunye ne-torsional.Yintsimbi enqamlezileyo eyoqoqosho kwaye isetyenziswa kakhulu ekwenzeni amacandelo ezakhiwo kunye namalungu oomatshini, afana neerodi zepetroleum, iishafti zokuhambisa iimoto, kunye neebhayisekile ukuphucula ukusetyenziswa kwezinto, ukwenza lula iinkqubo zokuvelisa, ukugcina izixhobo kunye neeyure zokucubungula, kwaye zisetyenziswe ngokubanzi kwimibhobho yentsimbi.
