Isishwankathelo seeMbhobho zeNsimbi zeDuctile
Sele kudlule iminyaka engaphezu kwama-70 ukususela oko kwaveliswa umbhobho wesinyithi othambileyo ngeminyaka yoo-1940. Ngenxa yamandla awo aphezulu, ubude bawo obuphezulu, ukumelana nokugqwala, ukumelana noxinzelelo, ukwakhiwa okulula kunye nezinye iimpawu ezininzi ezintle, umbhobho wesinyithi othambileyo lolona khetho lubalaseleyo kwihlabathi lanamhlanje lokuhambisa amanzi kunye negesi ngokukhuselekileyo. Isinyithi esithambileyo, esikwabizwa ngokuba yi-nodular iron okanye i-spheroidal graphite iron, sibonakala ngokubakho kwe-spheroidal graphite kwi-castings eziphumayo.

Iimpawu zeeDuctile Iron Pipes
Iipayipi zentsimbi ezixutyiweyo ziyafumaneka kububanzi obuphakathi kwe-80 mm ukuya kwi-2000 mm kwaye zifanelekile zombini ukuhanjiswa kwamanzi okusela kunye nokusasazwa kwawo (ngokuvumelana ne-BS EN 545) kunye nogutyulo lwamanzi amdaka (ngokuvumelana ne-BS EN 598). Iipayipi zentsimbi ezixutyiweyo kulula ukuzidibanisa, zinokubekwa kuzo zonke iimeko zemozulu kwaye zihlala zingenasidingo sokuzalisa kwakhona. Ukhuseleko lwayo oluphezulu kunye nokukwazi kwayo ukwamkela ukuhamba komhlaba kwenza ukuba ibe yeyona nto ifanelekileyo kwiindlela ezahlukeneyo zokusetyenziswa.
Amanqanaba eDuctile Iron Pipe esinokuyibonelela
Le theyibhile ilandelayo ibonisa zonke iintlobo zezinto zesinyithi ezithambileyo kwilizwe ngalinye.IUkuba ungumMelika, ungakhetha u-60-40-18, 65-45-12, 70-50-05 njl., ukuba uvela e-Australia, ungakhetha u-400-12, 500-7, 600-3 njl.

Izicelo ze-Ductile Iron
Intsimbi ethambileyo inamandla kwaye ithambile kunentsimbi engwevu. Ezo mpawu zivumela ukuba isetyenziswe ngokufanelekileyo kwiintlobo ngeentlobo zezicelo zoshishino, kubandakanya imibhobho, izinto zeemoto, amavili, iibhokisi zegiya, izindlu zepompo, iifreyimu zoomatshini kushishino lwamandla omoya, kunye nezinye ezininzi. Ngenxa yokuba ayiqhekeki njengentsimbi engwevu, intsimbi ethambileyo ikwakhuselekile ukuyisebenzisa kwiizicelo zokukhusela impembelelo, ezifana neebholadi.
