Incamake y'umuyoboro w'icyuma
Umuyoboro w'icyuma Umuyoboro ni imiyoboro ikozwe mucyuma. Icyuma cyitwa Ductile nicyuma cyitwa spheroidized grafite. Urwego rwo hejuru rwo kwizerwa rwicyuma ruva cyane cyane bitewe nimbaraga nyinshi, kuramba, hamwe ningaruka no kurwanya ruswa. Imiyoboro yicyuma isanzwe ikoreshwa mugukwirakwiza amazi meza no kuvoma ibishishwa, imyanda no gutunganya imiti. Iyi miyoboro yicyuma niterambere ritaziguye ryimiyoboro yicyuma yahindutse ubu hafi gusimburwa. Urwego rwo hejuru rwo kwizerwa rwimiyoboro yicyuma ihindagurika ni ukubera ibintu bitandukanye biruta byose. Iyi miyoboro niyo ishakishwa cyane nyuma yimiyoboro ya progaramu nyinshi.

| Gusaba | Umuyoboro wibyuma Umuyoboro ukoreshwa cyane cyane mu kwimura amazi y’imyanda, amazi yo kunywa no kuhira. |
Ibyiciro bitatu byingenzi byumuyoboro wicyuma
V-2 (icyiciro cya 40) Icyuma cyijimye, V-3 (65-45-12) Icyuma cyangiza, na V-4 (80-55-06) Icyuma cyangiza. Zitanga imbaraga nziza zo guhunika hamwe nubushobozi bwo guhindagurika cyane.
V-2 (icyiciro cya 40) Icyuma cyijimye, ASTM B48:
Iki cyiciro gifite imbaraga zingana zingana na 40.000 PSI nimbaraga zo kwikuramo 150.000 PSI. Gukomera kwayo kuva kuri 187 - 269 BHN. V-2 ikwiranye nuburyo bwo kwambara igororotse kandi ifite imbaraga zisumba izindi, ubukana, kwihanganira kwambara hamwe nubushyuhe bwo kuvura ubushyuhe bwicyuma kitemewe. Ikoreshwa cyane mugutwara no gushing porogaramu munganda za hydraulics.
V-3 (65-45-12) Icyuma cyangiza, ASTM A536:
Iki cyiciro gifite imbaraga zingana na 65.000 PSI, umusaruro wa 45,000 PSI, hamwe na 12%. Ubukomezi buri hagati ya 131-220 BHN. Imiterere yacyo nziza ya ferritic ituma V-3 itunganywa byoroshye mubyiciro bitatu byicyuma bigatuma iba imwe murwego rwo hejuru rwimashini zipimishije mubindi bikoresho bya ferrous; byahujwe cyane ningaruka nziza, umunaniro, amashanyarazi hamwe nubushobozi bwa magnetique. Ibyuma byangiza, cyane cyane imiyoboro, bikoreshwa cyane cyane kumirongo y'amazi n'imyanda. Iki cyuma nacyo gikunze kuboneka mubice byimodoka no mubikorwa byinganda.
V-4 (80-55-06) Icyuma cyangiza, ASTM A536:
Iki cyiciro gifite imbaraga zingana na 80.000 PSI, umusaruro utanga 55.000 PSI no kurambura 6%. Nimbaraga zisumba izindi zose uko ari eshatu, nkabakinnyi. Uru rwego rushobora kuvurwa ubushyuhe 100.000 PSI imbaraga zingana. Ifite igipimo cyo hasi ya 10-15% ugereranije na V-3 kubera imiterere ya pearlitike. Ihitamo cyane mugihe ibyuma byumubiri bikenewe.
Imiyoboro ya DI iruta ibyuma / PVC / HDPE
• Imiyoboro ya DI kandi izigama amafaranga yo gukora muburyo butandukanye harimo amafaranga yo kuvoma, amafaranga yo gukanda, hamwe n’ibyangiritse bishobora guturuka ku yandi mazu, bigatera kunanirwa nigiciro cyo gusana muri rusange.
• Ibiciro byubuzima bwa DI Pipes nimwe mubyiza byayo. Kubera ko bimara ibisekuruza, ni ubukungu gukora, kandi byoroshye kandi neza byashizweho kandi bigakorwa, igiciro cyigihe kirekire cyangwa ubuzima cyacyo kiri munsi byoroshye kuruta ibindi bikoresho.
• Umuyoboro wicyuma ubwacyo ni ibikoresho 100% byongera gukoreshwa.
• Irakomeye bihagije kugirango ihangane n’ibihe bikomeye cyane, uhereye ku muvuduko ukabije w’umuvuduko ukabije, kugeza ku isi iremereye n’imitwaro y’imodoka, kugeza ku butaka butajegajega.
• Kwiyubaka biroroshye kandi bifite umutekano kubakozi bashobora guca no gukanda Umuyoboro w'icyuma wa Ductile.
• Imiterere ya metero ya Ductile Iron Pipe bivuze ko umuyoboro ushobora kuba uri munsi yubutaka hamwe na moteri isanzwe.
•Imiyoboro ya DI itanga imbaraga zingana kurenza ibyuma byoroheje kandi ikagumana kwihanganira kwangirika kwicyuma.
