Emkhakheni wobunjiniyela bengqalasizinda ohlala ushintsha, ukuhlanganiswa kobuchwepheshe besimanje kuye kwaba yinto eshintsha umdlalo, ikakhulukazi emkhakheni wokufaka amapayipi. Njengoba amadolobha anda futhi isidingo sezakhiwo eziqinile sikhula, ukukhetha izinto ezifanele kubalulekile empumelelweni nasekuphileni isikhathi eside kwamaphrojekthi okwakha. Phakathi kwezinketho ezahlukene ezitholakalayo, ipayipi le-arc elingaphansi komhlaba eliyi-spiral (ipayipi le-SSAW) livele njengokukhetha okuthandwayo, ngezinzuzo zalo eziningi ezishintsha kabusha isimo sokuthuthukiswa kwengqalasizinda.
Ukubaluleka kweukunqwabelanisa amapayipiEkwakhiweni akunakweqiswa. Kungumgogodla wezakhiwo eziningi, okunikeza ukwesekwa okudingekayo ukuze kumelwane nokucindezeleka kwemvelo kanye nezidingo zokuthwala imithwalo. Eminyakeni yamuva nje, ukwethulwa kwamasu okukhiqiza athuthukile kuholele ekukhuleni kwepayipi le-SSAW, elikhiqizwa kusetshenziswa inqubo ehlukile yokushisela ejikelezayo. Le ndlela ayigcini nje ngokwandisa amandla nokuqina kwepayipi, kodwa futhi ivumela ukuguquguquka okukhulu ekuklanyweni nasekusetshenzisweni.
Enye yezinzuzo eziyinhloko zepayipi le-SSAW yikhono lalo lokubekezelela izimo zokucindezeleka okuphezulu, okwenza libe yindawo ekahle kakhulu yezinhlelo zokusebenza ezahlukahlukene zokufaka inqwaba. Ukwakheka kwalo okujikelezayo kunikeza ukushisela okuqhubekayo, kunciphisa kakhulu ingozi yokwehluleka ngaphansi kwemithwalo esindayo. Lokhu kubaluleke kakhulu kumaphrojekthi engqalasizinda lapho ukuphepha nokuthembeka kubalulekile khona. Ngaphezu kwalokho, ipayipi le-SSAW laziwa ngokumelana nokugqwala kwalo, okwandisa impilo yenkonzo yesakhiwo elisisekelayo, ekugcineni okuholela ekongeni izindleko zesikhathi eside.
Itholakala eCangzhou, eSifundazweni saseHebei, le fektri ibilokhu ihamba phambili ekukhiqizeni amapayipi ahlanganisiwe angaphansi kwe-spiral ac welded asezingeni eliphezulu selokhu yasungulwa ngo-1993. Le fektri ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla engu-RMB 680 million, futhi iqasha abasebenzi abanamakhono ababalelwa ku-680. Le ngqalasizinda eqinile yenza inkampani ikwazi ukuhlangabezana nezidingo ezikhulayo zemboni yokwakha ngenkathi igcina amazinga okulawula ikhwalithi aqinile.
Njengoba ubuchwepheshe besimanje buqhubeka nokuthuthuka, inqubo yokukhiqizaIpayipi le-SSAWsekuthuthuke kakhulu. Izinto ezintsha ezifana nokushisela okuzenzakalelayo kanye namasu okuhlola athuthukile aqinisekisa ukuthi ipayipi ngalinye lihlangabezana nezindinganiso eziphakeme kakhulu zekhwalithi kanye nokusebenza. Lokhu kuzibophezela ekwenzeni kahle akugcini nje ngokuthuthukisa idumela lenkampani, kodwa futhi kuletha ukuzethemba konjiniyela kanye nabakhi abathembele kulezi zinto zokwakha kumaphrojekthi abo.
Ngaphezu kwalokho, umthelela wezinto zokwakha emvelweni uyinkinga ekhulayo ezweni lanamuhla. Ipayipi le-SSAW likhiqizwa kucatshangelwa ukusimama, kusetshenziswa izinqubo ezisebenzisa amandla kahle kanye nezinto ezingasetshenziswa kabusha. Lokhu kuhambisana nokusunduza komhlaba wonke emikhubeni yokwakha eluhlaza, okwenza kube inketho ekhangayo yamaphrojekthi anobungani nemvelo.
Ekuphetheni, ukufaka ubuchwepheshe besimanje ezinqwabeni zamapayipi, ikakhulukazi ngokusebenzisa amapayipi e-SSAW, kuguqula ubunjiniyela bengqalasizinda. Lawa mapayipi anikeza izinzuzo ezifana namandla, ukuqina, kanye nokusimama, okwenza abe ukukhetha okuphezulu konjiniyela kanye nabakhi benkontileka. Njengoba imboni iqhubeka nokukhula, kusobala ukuthi ikusasa lokuthuthukiswa kwengqalasizinda lizothinteka kakhulu yizinto ezintsha kubuchwepheshe bezinqwabeni zamapayipi. Njengoba izinkampani ezifana neCangzhou zihola phambili, amathuba okudala izakhiwo eziqinile nezizinzile awapheli.
