Unokukhetha njani iibholithi ze-U

Xa ukhetha iibholithi ze-U, unokujonga oku kulandelayo:

1.Ubungakanani: Qinisekisa ububanzi kunye nobude beebholiti ezifunekayo.Oku kunokumiselwa ngokusekelwe kwizixhobo kunye nezicelo ozifunayo ukudibanisa.Qinisekisa ukuba ubungakanani bebholithi buhambelana nezinto eziza kudityaniswa ukuze kuqinisekiswe unxibelelwano olukhuselekileyo noluthembekileyo.

I-2.Izinto eziphathekayo: Khetha izinto ezifanelekileyo zebholithi ngokweemfuno zakho.Izinto eziqhelekileyo ezifumanekayo ziquka insimbi engenasici, i-carbon steel, njl. Izinto ezihlukeneyo zineendlela ezahlukeneyo zokuxhathisa i-corrosion, amandla, kunye neempawu zobunzima.

I-3.Imigangatho yomgangatho: Qinisekisa ukukhethwa kweebholiti ezihlangabezana nemigangatho efanelekileyo yomgangatho.Imigangatho eqhelekileyo ibandakanya i-ISO, i-DIN, i-ASTM, njl.

4.Imeko yesicelo: Qwalasela iimfuno ezikhethekileyo zendawo yesicelo, ezifana nokushisa okuphezulu, umswakama ophezulu, ukubola kweekhemikhali, njl. Ngokweemfuno zendalo, khetha iibholiti ezineengubo ezifanelekileyo okanye unyango lwezinto eziphathekayo ukuze kuphuculwe ukuqina kwazo kunye nokuxhathisa ukubola.

I-5.Iimfuno zomthwalo: Qonda iimfuno zomthwalo wokudibanisa okufunekayo kwaye ukhethe iibholiti ezinamandla okwaneleyo kunye nomthamo wokuthwala.Unokubhekisa kwimigangatho efanelekileyo okanye uqhagamshelane neengcali ukuze unqume ibakala elifanelekileyo le-bolt kunye nebakala lamandla.

Nceda uqaphele ukuba ezi zezinye zengqwalasela ezisisiseko zokukhetha iibholithi ze-U.Ngokusekwe kwiimfuno zakho ezithile zesicelo kunye nezinto ezinje ngemathiriyeli ekufuneka iqhagamshelwe, uthethwano olongezelelweyo neengcali kunokuba yimfuneko ukufumana iingcebiso ezichanekileyo kunye nesikhokelo.
