Amapayipi we-seker angabizi futhi amade ahlala afakiwe

Incazelo emfushane:

Njengomgogodla wokukhucululwa kwendle okusebenzayo kanye nengqalasizinda yezokuthutha kwamanzi angcolile, amapayipi ethu akhiwe ngokucophelela ukuze aqinisekise ukufakwa okungenamthungo kanye nokusebenza kahle. Ukuthi ufuna ukuthuthukisa uhlelo olukhona noma wakhe entsha, amapayipi ethu angabizi futhi ahlala isikhathi eside alungele noma yiliphi iphrojekthi.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Kwethulwa amapayipi ethu ashintshiwe, ahlala isikhathi eside Ifektri yethu yombuso eCangegzhou, esifundazweni saseHebei ibilokhu ikhiqiza ipayipi lensimbi eliphakeme kakhulu le-welded kusukela ngo-1993. Isikhungo sethu semitha yesikwele esingu-350,000 sihlome ngobuchwepheshe obuthuthukisiwe kanye nabasebenzi abanamakhono angama-680 ukuqinisekisa ukuthi imikhiqizo esiyinikezayo ihlangana ne amazinga aphezulu embonini.

Amapayipi ethu ensimbi eluhlaza anikela ngokuqina anikezela amandla ahlukile nokuqina, okwenza ukuba kube yingxenye ebalulekile ekwakhiweni nasekugcinweni kwezinhlelo zendle. Idizayinelwe ukumelana nezimo ezinzima, la mapayipi athembekile futhi abiza kakhulu, ahlinzeka ngesixazululo esingabizi komasipala kanye nosonkontileka. Ngenani lempahla eliphelele le-RMB 680 million, ukuzibophezela kwethu ekususweni kanye nokwenza kahle kuqinisekisa ukuthi imikhiqizo yethu zombili zihlala zihlala isikhathi eside futhi zisebenza kahle.

Njengomgogodla wokukhucululwa kwendle okusebenzayo kanye nengqalasizinda yezokuthutha kwamanzi angcolile, amapayipi ethu akhiwe ngokucophelela ukuze aqinisekise ukufakwa okungenamthungo kanye nokusebenza kahle. Ukuthi ufuna ukuthuthukisa uhlelo olukhona noma wakhe okusha, kwethu okungabizi futhi okuhlala isikhathi esideAmapayipi wendlezilungele noma yimuphi umsebenzi.

Inzuzo yomkhiqizo

1. Enye yezinzuzo eziphambili zepayipi lensimbi eluhlaza okotshani ukufinyeleleka kwalo. Hhayi kuphela la mapayipi kwezomnotho, kepha futhi anikela ngokuqina okuhlukile, abenze ikhambi lesikhathi eside sokukhucululwa kwendle kanye nokuthuthwa kwamanzi angcolile.

3. Lokhu kuqina kusho izindleko zokulungiswa okuphansi ngokuhamba kwesikhathi, kubenza babe ukukhetha okuthandwayo komasipala kanye nezinkampani zokwakha ngokufanayo.

Ukushiyeka komkhiqizo

1. Inqubo yokuqala yokufaka ingaba nzima futhi ingadinga imishini ekhethekile, engaphumela ezindlekweni eziphakeme kakhulu.

2.Kwathi lapho amapayipi angamelana nokukhulisa, asengathintwa izici ezithile zezemvelo, ezingathinta impilo yazo inkonzo ngaphansi kwezimo ezithile.

Isicelo

Ukukhetha okubonakalayo kubalulekile lapho kwakhiwa futhi kugcinwa izinhlelo zokuhambisa indle. Uma kukhulunywa ngamapayipi angabizi futhi ahlala isikhathi eside wokuhambisa indle, ipayipi le-Weld Welded lingukukhetha okuphezulu. Akugcini nje kuphela ukuthi la mapayipi ngokomnotho kepha futhi anikela ngokuqina okuhlukile, abenze ingxenye ebalulekile yokuthuthwa kwendle kanye nengqalasizinda yezokuthutha kwamanzi.

Kuvunguza insimbi ye-welded yensimbiziye zakwazi ukumelana nobunzima bezindawo ezinokhahlo, baqinisekise ukuthi bangahlangabezana nezidingo zezinhlelo zokuthuthwa kwendle esikhathini eside. Ukwakhiwa kwabo okugogekile kuhlinzeka ngesixazululo esithembekile somasipala kanye nezinkampani zokwakha abafuna ukutshala imali kwingqalasizinda ehlala isikhathi eside. Njengoba isidingo sezinhlelo zokulawula imfucuza ezisebenza kahle ziqhubeka zikhuphuka, ngakho-ke futhi isidingo samapayipi asezingeni eliphakeme sendle, futhi amapayipi ensimbi anezinwele ezinama-welded aphambili kule makethe.

Umthandi

Q1: Yini ipayipi le-welded lelded?

Amapayipi e-weldicro e-welded enziwe nge-welding imichilo enomoya yensimbi ndawonye, okuholela ekwakhekeni okuqinile futhi okuhlala isikhathi eside. Le ndlela yokwakha iqinisekisa amapayipi angamelana nezingcindezi eziphakeme nezimo zezemvelo ezinokhahlo, ezenze zilungele izinhlelo zokusebenza zendle. Impilo yabo ende ende isho ukushintshwa kanye nokulungiswa okumbalwa, okugcina kukusindisa imali ngokuhamba kwesikhathi.

Q2: Kungani ukhethe amapayipi angabizi futhi ahlala isikhathi eside wendle?

Ukutshala imali ngepayipi elishibhile futhi elihlala isikhathi eside kubalulekile kunoma yimuphi umsebenzi wokwakha. Ukuqina kwamapayipi ensimbi anezinwele ezinama-welded kusho ukuthi angamelana nobunzima bokuhambisa indle ngaphandle kokuhlupheka ekugqokeni nasekugqokeni. Lokhu kuthembeka kusho ukuphazamiseka okumbalwa nezindleko zokugcina, okuholela ohlelweni olusebenza kahle lwendle.
