Amapayipi ensimbi asenziwe isisekelo sengqalasizinda yesimanje, ikakhulukazi ezinhlelweni zokusatshalaliswa kwamanzi kanye nokulawulwa kwamanzi angcolile. Ayaziwa ngamandla awo nokuqina kwawo, lawa mapayipi akhiqizwa ukuze ahlangabezane namazinga ahlukahlukene, okuhlanganisa nokucaciswa kwe-ASTM A536, okuchaza izidingo zezinto ezisetshenziswayo zamapayipi ensimbi. Phakathi kwamabanga ahlukene atholakalayo, amapayipi ensimbi e-K9 grade ductile aphawuleka ngokukhethekile ngezakhiwo zawo zemishini ezithuthukisiwe, eziwenza afanelekele izicelo zokucindezela okuphezulu. Ipayipi yensimbi ye-DN800 ductile iron, enobubanzi obungu-800 millimeters, iyisinqumo esithandwayo samaphrojekthi amakhulu, ahlinzeka ngesixazululo esithembekile sokuthutha amanzi nokunye okusamanzi.
Ukufakwa kwamapayipi ensimbi okudonsa amanzi kukhulu, kusukela ezinhlelweni zokuphakelwa kwamanzi zikamasipala kuya ezimbonini. Ukumelana kwazo nokugqwala kanye nekhono lokumelana nokucindezela okuphezulu kuzenza zilungele kokubili ukufakwa okungaphezulu komhlaba nangaphansi komhlaba. Ngaphezu kwalokho, amapayipi ensimbi e-ductile avame ukusetshenziswa ezinhlelweni zokuvikela umlilo, lapho ukwethembeka kubaluleke kakhulu. Ukuhlukahluka kwala mapayipi kukuvumela ukuthi asetshenziswe ezindaweni ezihlukahlukene, okuhlanganisa izindawo zasemadolobheni, izindawo zasemakhaya, ngisho nasezindaweni eziyinselele. Njengoba amadolobha eqhubeka nokukhula kanye nezimfuno zengqalasizinda ziyanda, isidingo sezixazululo zamapayipi ezihlala isikhathi eside nezisebenza kahle njengamapayipi ensimbi edonsa amanzi siba bucayi nakakhulu.
Lapho kuxoxwa ngezigaba zezigaba zamapayipi e-iron ductile, kubalulekile ukuqonda ukubaluleka kwamabanga ahlukene. Ibanga le-K9, isibonelo, lidizayinelwe ukuphatha izilinganiso zokucindezela okuphezulu uma kuqhathaniswa namabanga aphansi, okulenza lifanelekele izinhlelo zokusebenza lapho ubungozi bokwenyuka kwengcindezi budlangile. Ukucaciswa kwamapayipi e-iron ductile, okuhlanganisa ukushuba kodonga nobubanzi, kubalulekile ekunqumeni ukusebenza kwawo ngaphansi kwezimo ezihlukahlukene. Ubudlelwano phakathi kobubanzi obujwayelekile kanye nokucindezela nakho kuwukucatshangelwa okubalulekile; njengoba ububanzi bukhula, isilinganiso sokucindezela kufanele sihlolwe ngokucophelela ukuze kuqinisekiswe ubuqotho besistimu. Lobu budlelwano bubaluleke kakhulu kumapayipi amakhulu, njengepayipi lensimbi le-DN800 ductile iron, okumele lenziwe ngobunjiniyela ukuze libambe imithwalo ebalulekile ye-hydraulic.
Njengoba isidingo somhlaba wonke samapayipi e-iron ductile siqhubeka sikhuphuka, izinkampani ezifana neJindalai Steel Company zihamba phambili ekusunguleni nasekukhiqizeni. Ngokuzibophezela kwekhwalithi kanye nokusimama, i-Jindalai Steel Company izitholele yona njengomholi ekukhiqizeni amapayipi ensimbi adonsa amanzi, ibambelela ezindinganisweni zamazwe ngamazwe kanye nezindlela ezihamba phambili. Ukugxila kwenkampani ocwaningweni nasekuthuthukisweni kuqinisekisa ukuthi imikhiqizo yabo ihlangabezana nezidingo eziguqukayo zemakethe, kuyilapho ibhekana nokukhathazeka kwemvelo. Njengoba amaphrojekthi engqalasizinda emhlabeni wonke ebeka eqhulwini ukuqina nokusebenza kahle, indima yamapayipi ensimbi edonsa amanzi, ikakhulukazi lawo ahlangabezana nezinga le-A536 kanye nezicaciso zebanga le-K9, ngokungangabazeki azohlala ebalulekile ekulolongeni ikusasa lokuphathwa kwamanzi kanye nezinhlelo zokusabalalisa amanzi.
Sengiphetha, amapayipi e-iron ductile, ikakhulukazi lawo ahlukaniswe ngaphansi kwe-ASTM A536 ne-K9 grade, ayizingxenye ezibalulekile kungqalasizinda yesimanje. Izicelo zabo zithatha izinhlobonhlobo zezimboni, futhi ukuqonda imininingwane yazo kanye nezici zokusebenza kwazo kubalulekile konjiniyela nabaphathi bephrojekthi ngokufanayo. Njengoba izinkampani ezifana ne-Jindalai Steel Company ziqhubeka nokusungula futhi zikhiqize amapayipi ensimbi e-ductile esezingeni eliphezulu, imboni ingalindela ukubona intuthuko ethuthukisa ukwethembeka nokusebenza kahle kwalezi zici ezibalulekile zengqalasizinda.
