Inzuzo yomkhiqizo

Enye yezinzuzo eziyinhloko zokusebenzisa amapayipi amakhulu okunqwabelanisa ububanzi yikhono lawo lokumelana nemithwalo esindayo. Lawa mapayipi enzelwe ukumelana nokucindezela okukhulu, okuwenza alungele ukusetshenziswa kwesisekelo esijulile kumaphrojekthi amakhulu wokwakha. Ububanzi bawo obukhulu buphinde bukhuphule ukugudluzwa kwenhlabathi, ngaleyo ndlela kuthuthukise ukuzinza nokunciphisa izinkinga zokuhlala. Ngaphezu kwalokho, inqubo yokushisela okuvunguzayo esetshenziswa ekwenziweni kwala mapayipi iqinisekisa isibopho esiqinile nesiqinile, sinciphisa ingozi yokuhluleka kwesakhiwo.

Ukushoda Komkhiqizo

Izindleko zokukhiqiza ipayipi yokunqwabelanisa yekhwalithi ephezulu yobubanzi obukhulu ingaba phezulu kunezinketho zendabuko, ezingathinta isabelomali sephrojekthi.

Ngaphezu kwalokho, inqubo yokufaka ingaba yinkimbinkimbi futhi idle isikhathi, idinga imishini ekhethekile kanye nabasebenzi abanamakhono. Uma kungaphathwa kahle, lokhu kungabangela ukubambezeleka kwezikhathi zephrojekthi.

Isicelo

Ezweni elikhula njalo lokwakhiwa nokuthuthukiswa kwengqalasizinda, isidingo sezinto eziqinile sibalulekile. Into eyodwa esithole ukunakwa okukhulu ipayipi lokunqwabelanisa lekhwalithi ephezulu, elinobubanzi obukhulu. Njengoba amaphrojekthi wokwakha akhula ngosayizi nokuba yinkimbinkimbi, isidingo sezixazululo zokunqwabelanisa ezinkudlwana, ezihlala isikhathi eside siba semqoka.

Ngokuthuthuka okusheshayo kwamaphrojekthi wokwakhiwa kwamadolobha kanye nengqalasizinda, ububanzi bamapayipi okunqwabelanisa buyaqhubeka nokwanda ukuze kuhlangatshezwane nezidingo zobunjiniyela besimanje. Ikhwalithi ephezulu eshiselwe i-spiralipayipi elikhulu lensimbi eliwububanziinqwaba ibalulekile ukuze kuhlinzekwe ukwesekwa okudingekayo nokuzinza kwezakhiwo ezihlukahlukene njengamabhuloho, izakhiwo kanye nezinsiza zasolwandle. Lawa mapayipi aklanyelwe ukumelana nemithwalo emikhulu kanye nezimo zemvelo ezinzima, ukuqinisekisa ukuphila isikhathi eside nokuphepha kwamaphrojekthi abawasekelayo.

Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukubaluleka kwepayipi lokunqwabelanisa ubukhulu bekhwalithi ephezulu akunakweqiwa. Ukuzibophezela kwethu kukhwalithi nokusungula izinto kuqinisekisa ukuthi sihlala singabalingani abathembekile embonini yezokwakha, sihlinzeka ngezinto ezibalulekile ezidingekayo kwingqalasizinda yesikhathi esizayo. Kungakhathaliseki ukuthi uhileleke kuphrojekthi enkulu noma iphrojekthi encane yokwakha, amapayipi ethu amakhulu okunqwabelanisa ububanzi akunikeza amandla nokwethembeka okudingayo.

FAQS

Q1: Liyini ipayipi elikhulu lokunqwabelanisa ububanzi?

Amapayipi okunqwabelanisa ububanzi obukhulu yizakhiwo eziyisilinda ezisetshenziselwa ukusekela imithwalo esindayo kumaphrojekthi wokwakha. Ububanzi bawo obukhulayo buhlinzeka ngomthamo omkhulu wokuthwala futhi kulungele izisekelo ezijulile ezimweni zenhlabathi eziyinselele.

Q2:Kungani ukhethe inqwaba yamapayipi ensimbi ashiselwe?

Izinqwaba zamapayipi ensimbi ashiselwe ku-Spiral zaziwa ngamandla azo aphakeme nokuqina. Inqubo ye-welding ye-spiral iqinisekisa i-seam eqhubekayo, ethuthukisa ubuqotho besakhiwo sepayipi. Le ndlela iphinde ivumele ukukhiqizwa kwamapayipi ensimbi amakhulu ububanzi ukuze kuhlangatshezwane nezidingo ezikhulayo zokwakha zanamuhla.

Q3: Enziwa kuphi la mapayipi?

Amapayipi ethu okunqwabelanisa amakhulu aphezulu aphezulu akhiqizwa eCangzhou, esifundazweni saseHebei. Ifektri yethu yasungulwa ngo-1993 futhi ihlanganisa indawo engamamitha-skwele angu-350,000 enempahla ephelele yezigidi ezingu-RMB 680. Sinabasebenzi abazinikele abangama-680 abazinikele ekukhiqizeni izixazululo zokunqwabelana ezisezingeni eliphezulu ezihlangabezana nezidingo eziqinile zomkhakha wezokwakha.
