Ibice bibiri byumupirani amahitamo azwi mubikorwa byinshi byinganda nubucuruzi, cyane cyane mugucunga amazi. Iyi mibande ni aUbwoko bwa kimwe cya kaneikoresha umupira wuzuye, usobekeranye, kandi uzunguruka kugirango ugenzure amazi, umwuka, amavuta, nandi mazi atandukanye. Kubice bibiri byumupira wumupira, PVC nibikoresho bisanzwe kubera kuramba kwayo no kurwanya ruswa.

Imikorere yibice bibiri byumupira byoroshye biroroshye ariko bifite akamaro. Iyo ikiganza cya valve gihinduwe, umupira uri muri valve urazunguruka kugirango wemere cyangwa wirinde gutemba. Ibi bituma biba byiza mubisabwa bisaba kugenzura neza imigendekere. Ibice bibiri byumupira wumupira nabyo byateguwe kugirango byoroshye kubungabunga no gusana, bituma biba igisubizo cyigiciro cyinganda nyinshi.

Kuri PVC ibice bibiri byumupira wumupira, ibi bikoresho bifite ibyiza byinshi. PVC (cyangwa polyvinyl chloride) ni ibikoresho bya termoplastique bizwiho kurwanya imiti myiza cyane, bigatuma biba byiza mubisabwa aho valve ihura namazi atandukanye. Byongeye kandi,PVC yoroshye kandi yoroshye kuyishyiraho no kuyikora. Irashobora kandi kuramba cyane, bigatuma ihitamo igihe kirekire kandi cyizewe kubice bibiri byumupira.

Imwe mumikorere yingenzi yibice bibiri byumupira wumupira ni ugutanga gufunga. Igishushanyo cya valve ikora kashe itekanye iyo ifunze, ikarinda gutemba kwamazi yagenzuwe. Ibi nibyingenzi mubisabwa aho kumeneka bihenze cyangwa biteje akaga. Ibikoresho bya PVC bikoreshwa mubice bibiri byumupira byerekana neza ko valve ikomeza gufungwa igihe kirekire, kabone niyo yaba ihuye n’imiti ikaze cyangwa ubushyuhe bukabije.

Ikindi kintu cyingenzi kiranga umupira wibice bibiri nubushobozi bwo kugenga amazi. Muguhindura gusa ikiganza, umuvuduko wikigereranyo urashobora guhinduka kugirango wuzuze ibisabwa byihariye bya porogaramu. Uru rwego rwo kugenzura ni ngombwa mu nganda nyinshi, kuva ku ruganda rutunganya amazi kugeza aho rutunganya imiti. Ibikoresho bya PVC bikoreshwa mubice bibiri byumupira wumupira byemeza ko bishobora kuzuza ibyifuzo byogukenera ibintu bitandukanye.

Ibice bibiri byumupira wamaguru nabyo bifite inyungu zo kuba byoroshye gusenya no kubungabunga. Ibi ni ukuri cyane cyane kuri PVC ibice bibiri byumupira wumupira, aho ibikoresho byoroheje kandi biramba bituma imirimo yo kubungabunga no gusana imirimo yoroshye kandi ihendutse. Ibi, bifatanije nubushobozi bwayo bwo gufunga no kugenzura ibintu, bituma PVC ibice bibiri byumupira wumupira wizewe kandi ufatika kubikorwa bitandukanye.

Muncamake, imikorere yumupira wibice bibiri (cyane cyane ikozwe muri PVC) nugutanga gufunga cyane, kugenzura imigendekere yamazi, kandi byoroshye kubungabunga. Iyo ugenzura imigendekere yamazi, umwuka cyangwa imiti, ibice bibiri byumupira wumupira ni amahitamo menshi kandi yizewe mubikorwa byinshi. Igishushanyo cyacyo cyoroshye ariko cyiza gifatanije nibyiza byibikoresho bya PVC bituma biba igisubizo cyiza kubikorwa bitandukanye.
