Ekwakhiweni kwamaphrojekthi engqalasizinda, ukukhethwa kwezinto zokwakha kuthinta ngqo ukuphepha kwesikhathi eside kanye nokusebenza kwephrojekthi. Ikakhulukazi ezinhlelweni zamapayipi, amapayipi ahlanganisiwe ajikelezayo, ngokusebenza kwawo okuhle kakhulu kwesakhiwo kanye nokusebenza kabanzi, abe yingxenye ebalulekile kumaphrojekthi obunjiniyela abalulekile njengokudluliselwa kwamanzi negesi. Ukuze kuthuthukiswe ukuqina kwawo kanye nokuzivumelanisa nezimo kwemvelo,Ipayipi elimboziwe elingu-3LPEubuchwepheshe buvele, buhlinzeka ngokuvikelwa kobunjiniyela okuqinile kohlelo lwamapayipi.
Ipayipi elihlanganisiwe elijikelezayo kanye nesembozo se-3LPE: Uhlelo lwesakhiwo oluvikela kabili
Amapayipi ahlanganisiwe ajikelezayo asetshenziswa kabanzi kumaphrojekthi ahlukahlukene epayipi lokucindezela ngenxa yezakhiwo zawo ezinhle kakhulu zemishini kanye nokuzivumelanisa nosayizi okuguquguqukayo. Kodwa-ke, ezimweni eziyinkimbinkimbi zejoloji kanye nezindawo zamakhemikhali, ukulwa nokugqwala kwangaphandle kwamapayipi kuba yisihluthulelo sokwandisa impilo yawo yesevisi. Ubuchwepheshe be-3LPE coating (i-polyethylene anti-corrosion coating enezingqimba ezintathu) buvele njengesixazululo esisebenzayo sokulwa nokugqwala ngaphansi kwalesi simo. Lobu buchwepheshe, ngesakhiwo esihlanganisiwe sesendlalelo sesisekelo se-epoxy powder, isendlalelo esiphakathi se-glue, kanye nesendlalelo sangaphandle se-polyethylene, buhlinzeka ngokulwa nokugqwala okuhle kakhulu, ukumelana nokushayisana, kanye nokumelana nokuguga kwe-amapayipi ahlanganisiwe ajikelezayo, futhi ifaneleka kakhulu kumapayipi okuthuthwa amabanga amade ezindaweni ezingaphansi komhlaba, ezingaphansi kwamanzi, kanye nezindawo ezigqwala kakhulu.
Kusukela ekukhiqizeni kuya ekuvikelweni: Izinzuzo zokukhiqiza okuhlanganisiwe
Njengebhizinisi elihamba phambili emkhakheni wokukhiqiza amapayipi ahlanganisiwe e-spiral eShayina, i-Cangzhou Spiral Steel Pipe Group Co., Ltd. izinikele ocwaningweni nasekukhiqizweni kwamapayipi ensimbi ahlanganisiwe kanye nemikhiqizo yawo yokumboza kusukela yasungulwa ngo-1993. Le nkampani itholakala eDolobheni laseCangzhou, eSifundazweni saseHebei, ihlanganisa indawo engamamitha-skwele angu-350,000, enomthamo wokukhiqiza waminyaka yonke wamathani angu-400,000 kanye nenani lomkhiqizo waminyaka yonke elingama-yuan ayizigidi eziyizinkulungwane ezingu-1.8. Ngokusekelwe ekukhiqizweni kwamapayipi ahlanganisiwe ahlanganisiwe ahlanganisiwe e-spiral, siphinde senze ngcono inqubo ngesikhathi esisodwa futhi silawule ikhwalithi yamapayipi ahlanganisiwe angu-3LPE (Amapayipi Ahlanganisiwe angu-3LPE), sifinyelele ekukhiqizweni okuhlanganisiwe kusukela ekwakhekeni komzimba wamapayipi kuya ekwelashweni kwangaphandle kokulwa nokugqwala, siqinisekise ukuthi imikhiqizo isebenza kahle kuyo yonke impilo yayo.
Ukuvikelwa kobunjiniyela akugcini nje ngamapayipi kuphela.
Kumaphrojekthi ahlukahlukene okwakha ingqalasizinda, ukuthembeka kwamapayipi kuthinta ngqo izindleko zokuphepha nokusebenza kanye nokugcinwa kwamaphrojekthi. Ipayipi elimbozwe nge-3LPE aligcini nje ngokwandisa impilo yesevisi yepayipi kodwa futhi linciphisa ingozi yokuvuza kanye nezingozi zemvelo ezibangelwa ukugqwala. Sizibophezele ekuhlinzekeni amakhasimende ngemikhiqizo yamapayipi ambozwe nge-coated ehlangabezana nezindinganiso zomhlaba wonke futhi efanelekile ezindaweni ezahlukene zobunjiniyela ngokuthuthukiswa okuqhubekayo kobuchwepheshe kanye nezinhlelo zokulawula ikhwalithi eziqinile.
Esikhathini esizayo, i-Cangzhou Spiral Steel Pipe Group izoqhubeka nokugxila kubuchwepheshe bezinto ezibonakalayo kanye nezinqubo zokukhiqiza, ikhuthaze ukusetshenziswa kobuchwepheshe bepayipi lokumboza le-3LPE emikhakheni eminingi, futhi inikeze izixazululo zepayipi eziqinile nezithembekile zentuthuko esimeme yengqalasizinda yomhlaba wonke.
