Ductile iron pombi dzave musimboti muzvivakwa zvemazuva ano, kunyanya mukugovera mvura uye masisitimu ekutonga kwemvura. Anozivikanwa nokuda kwesimba rawo uye kugara kwenguva refu, mapombi aya anogadzirwa kuti asangane nemiyero yakasiyana-siyana, kusanganisira iyo ASTM A536 tsanangudzo, iyo inotsanangura zvinodiwa zve ductile iron pipe zvinhu. Pakati pemagiredhi akasiyana anowanikwa, K9 giredhi ductile iron mapaipi anonyanya kucherechedzwa kune yavo yakagadziridzwa michina zvivakwa, zvichiita kuti ive yakakodzera kune yakakwirira-kudzvanywa kunyorera. Iyo DN800 ductile iron pombi, ine dhayamita yezita re800 millimeters, isarudzo yakakurumbira yemapurojekiti makuru, inopa mhinduro yakavimbika yekutakura mvura nezvimwe zvinwiwa.
Kushandiswa kwepombi dzesimbi dzakakura, kubva kumasisita ekupa mvura kumasisitimu kusvika kumaindasitiri ekushandisa. Kupokana kwavo necorrosion uye kugona kumirisana nehigh pressure inoita kuti ive yakanaka kune zvese zviri pamusoro-pasi uye pasi pevhu. Mukuwedzera, ductile iron pipes inowanzoshandiswa mumagetsi ekudzivirira moto, uko kuvimbika kunokosha. Kuchinja-chinja kwepombi idzi kunobvumira kuti ishandiswe munzvimbo dzakasiyana-siyana, kusanganisira nzvimbo dzemumaguta, nzvimbo dzekumaruwa, uye kunyange nzvimbo dzakaoma. Sezvo maguta ari kuramba achikura uye kudiwa kwezvivakwa kunowedzera, kudiwa kwekugara uye kunoshanda kwepombi mhinduro senge ductile iron pombi inotonyanya kukosha.
Paunenge uchikurukura nezve giredhi kupatsanurwa kwe ductile iron mapaipi, zvakakosha kuti unzwisise kukosha kwemagiredhi akasiyana. Iyo K9 giredhi, semuenzaniso, yakagadzirirwa kubata yakakwira kudzvanywa ratings kana ichienzaniswa neakaderera mamakisi, ichiita kuti ive yakakodzera kune maapplication uko njodzi yekumanikidza kusimuka kwakawanda. Izvo zvinotsanangurwa zve ductile iron mapaipi, kusanganisira kukora kwemadziro uye dhayamita, zvakakosha pakuona kushanda kwavo pasi pemamiriro akasiyana. Ukama huri pakati pezita rekuti dhayamita uye kumanikidzwa zvakare chinhu chakakosha kufunga; sezvo dhayamita ichiwedzera, chiyero chekumanikidza chinofanira kunyatsoongororwa kuti ive nechokwadi chekutendeseka kwehurongwa. Ukama uhwu hunonyanya kukosha kune mapombi akakura, akadai seDN800 ductile iron pombi, iyo inofanirwa kugadzirwa kuti ibate yakakosha hydraulic mitoro.
Sezvo kudiwa kwepasi rose kwepombi dzesimbi kunoramba kuchikwira, makambani akaita seJindalai Steel Company ari pamberi pekugadzira nekugadzira. Nekuzvipira kumhando uye kuenderera mberi, Jindalai Steel Company yakazvimisikidza semutungamiri mukugadzira mapaipi e ductile iron, achiomerera kune dzimwe nyika uye maitiro akanaka. Iyo kambani yakatarisana nekutsvagisa nekusimudzira inovimbisa kuti zvigadzirwa zvavo zvinosangana nezvinoda kuitika zvemusika, ukuwo vachigadzirisa zvinonetsa kwezvakatipoteredza. Sezvo mapurojekiti ezvivakwa pasi rese achiwedzera kukoshesa kusimba uye kushanda zvakanaka, basa remapombi esimbi, kunyanya ayo anosangana neA536 yakajairwa uye K9 giredhi yakatarwa, pasina mubvunzo acharamba akakosha mukuumba ramangwana rekutonga kwemvura nekugovera masisitimu.
Mukupedzisa, ductile iron mapaipi, kunyanya ayo akaiswa pasi peASTM A536 uye K9 giredhi, akakosha zvikamu muzvivakwa zvemazuva ano. Zvishandiso zvavo zvinotora maindasitiri akasiyana siyana, uye kunzwisisa kwavo maratidziro uye maitiro ekuita kwakakosha kune mainjiniya uye mamaneja emapurojekiti zvakafanana. Sezvo makambani akaita seJindalai Steel Kambani achiramba achigadzira uye kugadzira emhando yepamusoro ductile iron mapaipi, indasitiri inogona kutarisira kuona kufambira mberi kunowedzera kuvimbika uye kushanda zvakanaka kwezvinhu izvi zvakakosha zvezvivakwa.
