Isingeniso Somkhiqizo

Sethula amashubhu ethu ensimbi aguquguqukayo okusetshenziswa ezimbonini, aklanyelwe ukuhlangabezana nezidingo ezidingakalayo zezimboni eziningi. Imikhiqizo yethu ikhiqizwa efektri yethu yesimanje eCangzhou, eSifundazweni saseHebei, ehamba phambili embonini yensimbi kusukela ngo-1993. Njengoba inendawo engamamitha-skwele angu-350,000 kanye nempahla iyonke engu-RMB 680 million, siyaziqhenya ngokuba nabasebenzi abazinikele nabanekhono abangu-680 abaqinisekisa ukuthi yonke imikhiqizo esiyilethayo ihlangabezana nezindinganiso zekhwalithi ephezulu.

Inqubo yethu yokukhiqiza eyingqayizivele ihlukanisa amapayipi ethu ensimbi nomncintiswano. Aklanyelwe ukuqina nokuqina, la mapayipi ayakwazi ukumelana nokucindezeleka okuphezulu kwangaphakathi nangaphandle, okwenza afaneleke kakhulu ezinhlotsheni eziningi zezicelo. Kungakhathaliseki ukuthi usebenza ekwakheni, ku-oyili nasegesi, noma kunoma yimuphi omunye umkhakha wezimboni, amapayipi ethu akhelwe ukusebenza ngaphansi kwezimo ezinzima kakhulu.

Esinye sezici ezivelele ze-eguquguqukayo yethuipayipi lensimbi yensimbiukumelana kwazo okuhle kakhulu nokugqwala kanye nokuguqulwa. Le khwalithi ayigcini nje ngokwandisa impilo yamapayipi, kodwa futhi inciphisa izindleko zokulungisa, inikeze ikhambi elithembekile lezidingo zakho zezimboni. Ngokuzibophezela kwethu emisha kanye nekhwalithi, ungaqiniseka ukuthi imikhiqizo yethu izohlinzeka ngokusebenza okuhle kakhulu kanye nokuthembeka.

Inzuzo Yomkhiqizo

1. Enye yezinzuzo eziyinhloko zamapayipi ethu ensimbi yikhono lawo lokubekezelela ukucindezeleka okuphezulu kwangaphakathi nangaphandle. Lokhu kuwenza afaneleke kakhulu ezimbonini ezifana nowoyela negesi, ezokwakha kanye nezokukhiqiza.

2. Lawa mapayipi aklanyelwe ukumelana nokugqwala nokuguqulwa, okuqinisekisa impilo yesevisi ende kanye nezindleko zokulungisa eziphansi.

3. Ukuguquguquka kwazo kuvumela ukuthi zisetshenziswe ezinhlobonhlobo zezicelo, kusukela ekudluliseni uketshezi kuya ekusekelweni kwesakhiwo.

Ukushoda komkhiqizo

1. Ipayipi lensimbikungaba nzima kunezinye izinto ezifana nepulasitiki noma izinto ezihlanganisiwe, okungadala izinselele ngesikhathi sokufakwa nokuthuthwa.

2. Nakuba zimelana nokugqwala, azivikelekile ngokuphelele ekugqwaleni, ikakhulukazi ezindaweni ezinzima. Ukunakekelwa njalo kanye nokuvikelwa kungadingeka ukuze kwandiswe isikhathi sazo sokusebenza.

Imibuzo Evame Ukubuzwa

Q1: Yini ehlukile ngalezi zipayipi zensimbi?

Inqubo yokukhiqiza eyingqayizivele esetshenziswa ukukhiqiza la mapayipi ensimbi ensimbi ikhulisa kakhulu amandla awo nokuqina kwawo. Ngokungafani namapayipi ajwayelekile, la mapayipi aklanywe ukuze amelane nokucindezeleka okuphezulu kwangaphakathi nangaphandle, okwenza afanelekele izindawo zezimboni ezidinga kakhulu. Ukwakhiwa kwawo okuqinile kuqinisekisa isikhathi eside futhi kunciphisa isidingo sokushintshwa njalo.

Umbuzo 2: Ingabe la mapayipi amelana nokugqwala?

ngokuqinisekile! Esinye sezici eziyinhloko zamapayipi ethu ensimbi ukumelana nokugqwala nokuguquka. Lesi sici sibalulekile ekusetshenzisweni kwezimboni ezifana nowoyela negesi, ukwakhiwa kanye nokucubungula amakhemikhali, okuvame ukuvezwa ezimweni ezinzima. Ukumelana nokugqwala kuqinisekisa ukuthi amapayipi agcina ubuqotho bawo isikhathi eside, enikeza ikhambi elithembekile lamaphrojekthi ahlukahlukene.

Q3: La mapayipi akhiqizwa kuphi?

Isizinda sethu sokukhiqiza amapayipi ensimbi ensimbi sitholakala eDolobheni laseCangzhou, eSifundazweni saseHebei, kanye nefektri ethuthukisiwe ehlanganisa indawo engamamitha-skwele angu-350,000. Le nkampani yasungulwa ngo-1993 futhi ikhule ngokushesha ngempahla iyonke engama-yuan ayizigidi ezingu-680 kanye nabasebenzi abangu-680. Ulwazi lwethu olucebile kanye nokutshalwa kwezimali kobuchwepheshe kusenza sikwazi ukukhiqiza amapayipi asezingeni eliphezulu ahlangabezana nezidingo ezahlukahlukene zamakhasimende ethu.
