Ukuguquguquka kwayo kwenza ukuba ibe lukhetho olusebenzayo kwiinkqubo ezininzi zemibhobho kunye neenkqubo zoncedo.
4. Amandla okusetyenziswa koxinzelelo oluphezulu kunye nobushushu obuphezulu
Iindidi zentsimbi yekhabhoni ezifana ne-ASTM A105 (eyenziwe ngomatshini) kunye ne-A216 WCB (eyenziwe ngomatshini) zisetyenziswa kakhulu kwi-uxinzelelo oluphezulukwayeubushushu obuphezuluinkonzo. Ezi zinto zixhasa iiklasi zoxinzelelo kuquka iKlasi ye-150, 300, 600, nangaphezulu, kuxhomekeke kuyilo.
5. Ubomi beNkonzo ende kwiMizi-mveliso
Amandla oomatshini entsimbi yekhabhoni anceda ekumelaneni nokudinwa, ukungcangcazela, kunye namandla ehammer yamanzi. Ngokugqunywa ngokufanelekileyo kunye nokugcinwa rhoqo, ezi valivu zinokubonelela ngobomi obude benkonzo nokuba zikwiindawo zoshishino ezifuna amandla amaninzi.
