Amapayipi Ensimbi Ekhwalithi Ephezulu Athengiswayo

Incazelo emfushane:

Amapayipi ethu ensimbi yekhabhoni ahlanganisiwe nge-spiral aklanyelwe ukumelana nezimo ezinzima, ukuqinisekisa ukuthembeka nokuphila isikhathi eside. Kungakhathaliseki ukuthi udinga amapayipi kumaphrojekthi engqalasizinda, ukusetshenziswa kwamandla noma okunye ukusetshenziswa kwezimboni, imikhiqizo yethu yenzelwe ukuletha ukusebenza okuphezulu.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Amapayipi ethu enziwa ngokugoqa insimbi eyakhiwe ngekhabhoni ephansi ibe yizimbobo zamapayipi ngama-engeli aqondile ajikelezayo, kulandelwe inqubo eqinile yokushisela ukuqinisekisa ubuqotho nokuqina kwemithungo. Le ndlela yokukhiqiza entsha isivumela ukuthi sakhe amapayipi ensimbi anobubanzi obukhulu angagcini nje ngokuba aqinile kodwa futhi aguquguqukayo, okwenza afaneleke kakhulu ekusetshenzisweni okuhlukahlukene kusukela ekwakheni kuya ekuthuthweni kukawoyela negesi.

Ifektri yethu itholakala enkabeni yeDolobha laseCangzhou, eSifundazweni saseHebei futhi ibilokhu ihola embonini yamapayipi ensimbi selokhu yasungulwa ngo-1993. Ifektri ihlanganisa indawo engamamitha-skwele angu-350,000 futhi ifakwe ubuchwepheshe kanye nemishini yesimanje, okusenza sikwazi ukukhiqiza amapayipi ensimbi asezingeni eliphezulu ahlangabezana nezindinganiso zomhlaba wonke. Njengoba sinempahla ephelele engu-RMB 680 million kanye nabasebenzi abazinikele abangu-680, siyaziqhenya ngokuzibophezela kwethu ekwenzeni kahle kanye nokwaneliseka kwamakhasimende.

Ukuhlolwa Kwamanzi

incazelo yomkhiqizo1

Ipayipi kufanele imelane nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo wokushisela noma umzimba wepayipi.
Ama-jointer akudingeki ahlolwe ngamanzi, uma nje izingxenye zamapayipi asetshenziswe ekumaka ama-jointer zihlolwe ngempumelelo ngamanzi ngaphambi kokusebenza kokujoyina.

Inzuzo Yomkhiqizo

1. Enye yezinzuzo eziyinhloko zamapayipi ethu ensimbi yekhabhoni ahlanganisiwe nge-spiral yikhono lokukhiqiza amapayipi amakhulu ububanzi. Lokhu kufezwa ngenqubo yokukhiqiza eyingqayizivele ehilela ukugoqa insimbi ethambile yesakhiwo ibe yizimbobo zamapayipi nge-engeli ethile ye-helical bese kushiselwa imithungo.

2. Le ndlela ayigcini nje ngokwandisa amandla nokuqina kwepayipi, kodwa futhi ivumela ukuguquguquka ekuklanyweni nasekusetshenzisweni kwayo.

3. Amapayipi ethu amelana nokugqwala futhi angamelana nokucindezeleka okuphezulu, okwenza afaneleke kakhulu ezimbonini ezahlukahlukene okuhlanganisa uwoyela negesi, ukuhlinzekwa kwamanzi, kanye nokwakha.

Ukushoda komkhiqizo

1. Inqubo yokukhiqiza, nakuba isebenza kahle, ingaholela ekushintsheni kwekhwalithi uma ingaqashelwa eduze.

2. Izindleko zokuqala zekhwalithi ephezuluipayipi lensimbikungase kube phezulu kunezinye izindlela ezisezingeni eliphansi, okungaba yinto okufanele icatshangelwe kumaphrojekthi athinta isabelomali.

3. Nakuba amapayipi ethu eklanyelwe ukuqina, angadinga ukulungiswa njalo ukuqinisekisa ukuthi ahlala isikhathi eside, ikakhulukazi ezindaweni ezinzima.

Imakethe

Izimakethe zethu ezibalulekile zisakazeke kuzo zonke izifunda, okuqinisekisa ukuthi siyakwazi ukuhlangabezana nezidingo zamakhasimende ethu emhlabeni wonke. Siyaziqhenya ngokuhlinzeka ngamapayipi ensimbi asezingeni eliphezulu angagcini nje ngokuhlangabezana kodwa futhi adlula amazinga embonini. Ukuzinikela kwethu ekulawuleni ikhwalithi kanye nokwaneliseka kwamakhasimende kusitholele idumela lokuba ngumhlinzeki othembekile embonini yensimbi.
