Ziziphi iinkcukacha kunye neemodeli ze-rebar yebanga lesithathu?
Okwangoku, ulwahlulo lwentsimbi yesithathu lusekelwe ikakhulu kwi-diameter ye-nominal.Iimpawu eziphambili ziyi-8, 10, 12, 14, 16, 18, 20, 25, 30, 32, 40, 50, njl. Ukongeza, ukuba kukho ezinye iinkcukacha kwikhontrakthi, Ukuba kucacisiwe, imveliso inokuqhutywa kwakhona. ngaphandle ngokuhambelana namalungiselelo ekhontrakthi.Ubude bentsimbi ngokuqhelekileyo buza kwiinkcukacha ezimbini: iimitha ezili-9 kunye neemitha ezili-12.Amaxabiso eentsimbi ezinobubanzi obuhlukeneyo kunye nobude ahlukeneyo.Ixabiso lentsimbi yeemitha ezili-9 eziveliswa ngabanye abavelisi liphezulu kunelo lentsimbi yeemitha ezili-12.Ixabiso elithile linokumiselwa ngokweemfuno zakho.Thetha ngezidingo zokwenene.
Indlela yokukhetha i-rebar yebanga lesithathu?
Xa kuthengwa, kufuneka uqale ubeke ingqalelo kumgangatho wentsimbi.Ububanzi obuqhelekileyo kunye nobude bentsimbi kufuneka buhlangabezane nemigangatho yomgangatho wokuvelisa.Ukongeza, iimveliso ezinobukhulu obuncinci bobukhulu zidla ngokuba namandla okumelana noxinzelelo kwaye zifaneleke ngakumbi ukusetyenziswa ekwakhiweni kwezakhiwo ezineemfuno eziphezulu zomgangatho.Ukongeza, kusenokubakho iimveliso ezithile kwisitokhwe esinamaxabiso aphantsi ngokwentelekiso, kodwa ingqwalasela kufuneka ihlawulwe ekuxhathiseni ukudinwa.
