Mapaipi esimbi akagadzirwa nesimbi dzakapfava akaonekwa sesarudzo inofarirwa mukushandiswa kwakasiyana-siyana, kunyanya mumichina yemvura uye yekudhonza mvura. Mapaipi aya akagadzirwa neJindalai Steel Group, anozivikanwa nekusimba kwawo kwakanyanya uye kuchinjika kwawo zvichienzaniswa nemapaipi esimbi akaumbwa nesimbi. Hunhu hwakasiyana hwesimbi dzakapfava, kusanganisira kugona kwayo kutsungirira kumanikidzwa kwakanyanya uye kuramba ngura, zvinoita kuti ive chinhu chakanakira mapurojekiti ezvivakwa. Sezvo kukura kwemaguta kuri kuramba kuchikwira, kudiwa kwemhinduro dzemapaipi akavimbika uye anogara kwenguva refu hakuna kumbobvira kwanyanya kukosha, uye mapaipi esimbi akagadzirwa nesimbi akapfava ndiwo ari pamberi pekushanduka uku.
Chimwe chezvinhu zvakakosha zvemapaipi esimbi akagadzirwa nesimbi isystem yavo yekuyera, iyo inoaisa mumapoka zvichienderana nehunyanzvi hwavo hwemakanika. Magiredhi akajairika anosanganisira Kirasi 50, Kirasi 60, neKirasi 70, uye giredhi rega rega richiratidza simba rekudhonza rechinhu chacho. Magiredhi aya anovimbisa kuti mainjiniya vanogona kusarudza pombi yakakodzera yekushandisa zvakananga, kungave kuri kwemapaipi esimbi akagadzirwa nesimbi akagadzirwa nesimbi kana mapaipi esimbi akagadzirwa nesimbi akagadzirwa nesimbi akagadzirwa nesimbi. Kuchinja-chinja kwemapaipi aya kunoita kuti ashandiswe mumamiriro akasiyana-siyana, kusanganisira masisitimu emvura emakanzuru, masisitimu etsvina, uye mashandisirwo emaindasitiri, zvichiratidza kugona kwawo kusangana nezvinodiwa zvakasiyana-siyana zveinjiniya.
Kuwedzera kune hunhu hwavo hwemakanika, mapaipi esimbi ane ductile anoshandiswawo nehunyanzvi hwepamusoro hwekurapa ngura. Kurapa uku kwakakosha pakuwedzera hupenyu hwemapaipi, kunyanya munzvimbo dzaanogona kusangana nemamiriro evhu ane hukasha kana zvinhu zvinoparadza. Matekiniki akadai se epoxy coating uye polyethylene encasement anowanzo shandiswa kuwedzera kugara kwenguva refu kwemapaipi esimbi ane ductile. Jindalai Steel Group yakazvipira kushandisa matekinoroji aya, ichiva nechokwadi chekuti zvigadzirwa zvavo hazvingosviki chete asi zvinopfuura mwero weindasitiri wekudzivirira ngura.
Hunhu hwemapaipi esimbi ane ductile hunopfuura simba rawo uye kuramba ngura. Anozivikanwawo nekushanda kwawo kwakanaka kwe hydraulic, izvo zvakakosha pakufamba kwemvura zvakanaka mumasisitimu ekupa. Kureba kwemukati kwemapaipi esimbi ane ductile kunoderedza kurasikirwa nekukweshana, zvichibvumira kutakurwa kwemvura kwakanaka. Uyezve, kuchinjika kwawo kunobvumira kuiswa nyore uye kuchinjika kunzvimbo dzakasiyana-siyana, zvichiita kuti ave sarudzo inoshanda kune mainjiniya nevanoita mabasa akafanana. Kusanganiswa kwezvivakwa izvi kunoita kuti mapaipi esimbi ane ductile ave mhinduro yakavimbika yezvinetso zvemazuva ano zvezvivakwa.
Pamwero wepasi rose, mapaipi esimbi ane ductile awana kuzivikanwa nekushanda kwawo mumabasa akasiyana-siyana. Nyika pasi rose dziri kuramba dzichishandisa tekinoroji yesimbi ine ductile mukupa mvura uye masisitimu emvura, dzichiziva mabhenefiti enguva refu ekudyara mari mumhinduro dzemapaipi dzinogara kwenguva refu uye dzinoshanda. Jindalai Steel Group yakaita basa guru mukuita uku kwepasi rose, ichipa mapaipi esimbi ane ductile emhando yepamusoro anosangana nezvinodiwa zvepasi rose. Sezvo nyika ichiramba ichiisa pamberi zvivakwa zvinogara kwenguva refu uye zvinogara kwenguva refu, basa remapaipi esimbi ane ductile pasina mubvunzo richawedzera, richisimbisa nzvimbo yaro sedombo guru remabasa emazuva ano einjiniya.
Mukupedzisa, mapaipi esimbi ane ductile anomiririra kufambira mberi kukuru muhunyanzvi hwemapaipi, zvichipa musanganiswa wesimba, kuchinjika, uye kuramba ngura. Nemhando dzakasiyana-siyana uye nzira dzepamusoro dzekudzivirira ngura, mapaipi aya akakodzera kushandiswa kwakasiyana-siyana, kubva pakupa mvura yemumaguta kusvika kumasisitimu emvura yemumaindasitiri. Sezvo kudiwa kwezvivakwa zvinovimbika kuri kuwedzera, Jindalai Steel Group inoramba yakazvipira kupa mapaipi esimbi ane ductile emhando yepamusoro anosangana nezvinodiwa zviri kuchinja mumusika wepasi rose.
