Eminyakeni eyikhulu edlule, onjiniyela baseMelika abazinikele bafaka ipayipi lensimbi ukuze bakhe izinhlelo zamanzi zezwe.Lo mkhiqizo oqinile, ophephile, futhi onokwethenjelwa uye wamelana novivinyo lwesikhathi.OkwesimanjeIpayipi lensimbi elinemboboyenziwa ukuthi ihlale ngaphezu kweminyaka eyi-100, futhi iwumkhiqizo okhetheka ngokwemvelo ngenxa yokuqukethwe kwawo okugaywe kabusha, ukonga amandla ngenkathi usebenza, ukuqina kwawo, ukugaywa kwawo kabusha kanye nangenxa yokuzibophezela kwemboni ye-Ductile Iron Pipe.
Izinzuzo zihlanganisa:
Idinga ukulungiswa okuncane kakhulu uma isifakiwe futhi yakhelwe ukuthi ihlale okungenani iminyaka eyi-100.
Ngokombiko wakamuva we-American Water Works Association, impilo yesevisi ehlongozwayo ye-Ductile Iron Pipe yesimanje okungenani iminyaka eyi-105.Kukhona ipayipi lensimbi eliningi elisebenzayo e-US kunanoma iyiphi enye impahla yamapayipi, futhi i-Ductile Iron Pipe inokuphila kwesevisi ende kunanoma iyiphi into emakethe namuhla.
Njengoba inokuqukethwe okungama-98% okugaywe kabusha, i-Ductile Iron Pipe yona ngokwayo iwu-100% wempahla egaywa kabusha.
2. Izindleko eziphansi ezivela ekukhuleni komthamo wokugeleza ziholela ekongeni ugesi okubalulekile phakathi nokuphila kwepayipi lisebenza.I-Ductile Iron yonga imali.
Inamandla ngokwanele ukumelana nezimo ezinzima kakhulu, kusukela ekufakweni kwengcindezi ephezulu, emhlabeni onzima kanye nemithwalo yethrafikhi, kuya ezimweni zenhlabathi ezingazinzile.
3. Ayizwani nokugqwala enhlabathini eminingi, futhi ngokuvamile idinga kuphela ukuvalelwa kwe-polyethylene okusebenzayo, ukongayo, i-sheathing exegayo efanekiselwa yi-American Water Works Association, ezindaweni ezinolaka.
Ngamandla ayo, ukuqina, kanye nesakhiwo esilondolozayo, i-Ductile Iron iyipayipi elikhethwayo lokuvikela ekukhuphukeni nasekukhuphukeni kwengcindezi phakathi neminyaka.
4. Ukufakwa kulula futhi kuphephile kubasebenzi abakwazi ukusika futhi bathinte Ipayipi Lensimbi Elihlanganisiwe esizeni.
5. I-Ductile Iron Pipe iqinile futhi imelana nokulimala ngesikhathi sokuphatha nokufakwa.
6. Ubume bensimbi be-Ductile Iron Pipe busho ukuthi ipayipi lingatholakala kalula ngaphansi komhlaba nezikhombi zamapayipi ezivamile.
Izingozi Zokusebenzisa i-PVC
Ukukhathazeka okujulile, okukhathaza kakhulu nokufakazelwe kwezempilo kuhlotshaniswa ne-polyvinyl chloride (PVC).Ukukhathazeka kukhulu kangangokuthi amadolobha, amadolobhakazi kanye nezinkampani emhlabeni wonke ziyakuvimbela noma zibekela imingcele ukusetshenziswa kwayo.
1. Ukukhiqizwa kwe-PVC kwakha amakhemikhali ayingozi njengama-dioxin nobunye ubuthi obuboniswe ukuthi bubangela umdlavuza kanye nokukhubazeka kokuzalwa.Eqinisweni, kuye kwatholakala “amaqoqo omdlavuza” eduze nezimboni ezikhiqiza i-PVC.
Ngenkathi imboni yamapayipi e-PVC iphakamisa umkhiqizo wayo njengenye indlela engcono kune-Ductile Iron Pipe, amaqiniso asikisela okuhlukile:
2. Ipayipi le-PVC libuthakathaka.Ayikwazi ukumelana nengcindezi, ikakhulukazi izingcindezi ezijwayelekile ezihlukanisayo eziholela ezindaweni ezibuthakathaka.
Ukuphila isikhathi eside kwepayipi le-PVC kuncike ekucindezelekeni nasesikhathini-ukucindezeleka okukhulu, ngokushesha kuzohluleka.
3. Ipayipi le-PVC liyazwela emazingeni okushisa azungezile (emazingeni okushisa aphansi, i-PVC iya ngokuya iba brittle futhi ingaphuka kalula, kuyilapho ezindaweni ezifudumele i-PVC iba buthakathaka).
4. Ipayipi le-PVC lilahlekelwa amandla okuthinta uma lichayeke emisebeni ye-ultraviolet - i-PVC ingalahlekelwa kufika ku-34% wamandla ayo omthelela ngemva cishe konyaka owodwa wokuchayeka emisebeni ye-UV.
5. I-PVC inezindleko eziphezulu zokupompa namandla.Kubiza kakhulu ukupompa ngepayipi le-PVC kune-Ductile Iron Pipe ngoba i-Ductile Iron Pipe inobubanzi obukhudlwana bangaphakathi.
6. Ipayipi le-PVC linzima kakhulu ukulifaka.Idinga ukugcwaliswa ngemuva okukhulu kakhulu, futhi kufanele ifakwe ngentambo yokulandelela ukuze kuqinisekiswe ukuthi ingatholakala ngokuzayo.
7. Ipayipi le-PVC lisengozini yokulimala kusuka ezimeni zangempela zokuthumela nokuphatha.Ukuklwebheka okujulile kunobukhulu be-dime kungalimaza bonke ubude bepayipi le-PVC.
8. Ukuthepha ipayipi le-PVC kunzima futhi kudla isikhathi futhi kungaba yingozi - okuholela ekuqhekekeni kwamapayipi, izisebenzi ezilimele, nokulahlekelwa amanzi kakhulu.
9. Ukuthola indawo evuzayo epayipini le-PVC kunzima kakhulu.Izindlela eziningi zokuthola indawo zihilela ukudlulisa amaza omsindo phansi epayipini, amaza omsindo angahambi kahle emapayipini epulasitiki.
10. Ipayipi le-PVC lingase libe nokuphazamiseka okuphindaphindiwe ku-chain chain yayo, okuye kwaholela ezazisweni eziningana "ze-force majeure" zokulahlekelwa umthamo wokukhiqiza kumakhasimende ayo.
