Ipayipi lesikwele uhlobo lwegamaipayipi lesikwelefuthiipayipi elingunxande, okungukuthi, amapayipi ensimbi anobude obulinganayo futhi obungalingani. Igoqwa kusuka ku-strip steel ngemuva kokwelashwa kwenqubo. Ngokuvamile, insimbi ye-strip iyakhishwa, ilinganiswe, igoqwe, ishiselwe ukuze yakhe ipayipi eliyindilinga, igoqwe ibe ipayipi eliyisikwele, bese isikwa ubude obudingekayo.
Ngokukhuthazwa okuqhubekayo kwezinguquko zesakhiwo sohlangothi lokunikezela, imboni yeshubhu eyisikwele neyonxande ibonise ukuthambekela okuhle. Ngokusho kwedatha, ngemva kweminyaka ecishe ibe yishumi yentuthuko, imboni yeshubhu elingunxande laseShayina iye yathuthukiswa ngokuqhubekayo futhi yathuthukiswa esakhiweni somkhiqizo, izinga lekhwalithi, imishini yobuchwepheshe nezinye izici, futhi isibe izwe elingokoqobo elikhiqizayo emhlabeni wonke lamashubhu angunxande, futhi liyanyakaza. ngasembusweni womhlaba weithubhu elingunxandeimboni.
Abakhiqizi bensimbi eluhlaza embonini ekhuphuka nomfula yamapayipi ayisikwele nawonxande, futhi asetshenziswa kabanzi ekwenziweni kwemishini, ukwakhiwa, insimbi, izimoto zezolimo, izindawo zokugcina izithombo zezolimo, imboni yezimoto, ojantshi, onogada bomgwaqo onguthelawayeka, amafreyimu esitsha, ifenisha, umhlobiso nezakhiwo zensimbi imboni engezansi. Manje isetshenziswa kakhulu ekwakhiweni kwezindawo ezinkulu, njengezikhumulo zezindiza, izinkundla zemidlalo, iziteshi, njll., ezisetshenziswa njengezinhlaka zensimbi eziyinhloko, izindonga, njll., kanye nokwakhiwa kwezakhiwo zokuhlala zensimbi yensimbi; Ngaphezu kwalokho, isetshenziswa njengesisekelo nokusekelwa kwemishini embonini yemishini, imoto isetshenziswa njengokulungiswa kabusha kwamagida namaloli amakhulu, umzimba wamabhayisikili amathathu ezolimo, futhi isetshenziselwa ukushisela amafreyimu ahlukahlukene ngezinhloso zomphakathi. Imikhiqizo yamapayipi ashiselwe imvamisa ephezulu isetshenziswa kakhulu embonini yezokwakha kumapayipi ashiselwe ashiselwe imvamisa ephezulu kanye namapayipi angamanxande ezakhiwo kanye nensimbi yesakhiwo esakhiwe ngendlela ebandayo ezakhiweni, lapho amapayipi ayisikwele nawonxande enza ngaphezu kuka-50%. Ngokombono woomakhenikha besakhiwo nomnotho, inhlanganisela yamapayipi ayisikwele kanye nonxande iyinhlanganisela engcono kakhulu yemboni yezokwakha, engakwazi ukufeza ukuthuthukiswa kwezimboni zezitshalo zezimboni kanye nokwakhiwa kwezindawo zokuhlala.
Onyakeni omusha, ukuhlinzekwa kweshubhu elingunxande nesidingo saseChina kuzothambekela ekubeni ngcono kunokuba kubi. Lokhu kungenxa yokuthi, ngokombono wesidingo esikhulu, isimo sangaphandle somnotho waseChina sizoba sibi kakhulu ngo-2019, okuzokwandisa ingcindezi ephansi emnothweni waseChina. Ngenxa yalesi sizathu, umnyango othatha izinqumo kumele uqinise ukuguqulwa komjikelezo, okuhlanganisa inqubomgomo yezimali engathathi hlangothi futhi exegayo, inqubomgomo yezimali esebenzayo, ikakhulukazi ukusimamisa ukutshalwa kwezimali kwingqalasizinda, kanye nokugcina ukutshalwa kwezimali kwezakhiwo kusezingeni eliphezulu, ukuze kugcinwe ukukhula komnotho waseShayina. ebangeni elifanele, Ibophezelekile ukukhuthaza ukukhula okuqhubekayo kwesidingo esiphelele samashubhu angama-rectangular aseChina.
Kusukela ohlangothini lokuhlinzeka, ngemva kweminyaka eminingana yemizamo eqhubekayo, i-China yenze impumelelo enkulu ekunciphiseni amandla okukhiqiza insimbi nensimbi kanye nokuqedwa kwe "ground bar steel". Amandla okukhiqiza insimbi nensimbi ancishiswe ngamakhulu ezigidi zamathani. Ngakho-ke, ngokwengqondo, ngokuncipha kwesisekelo samandla okukhiqiza insimbi, ukukhula okuqhubekayo nokuqinile kokukhishwa kwensimbi kuyoba nzima ukusekela.
Akukhona lokho kuphela, ngemva kweminyaka emibili elandelanayo yokukhula okuqinile kwensimbi (insimbi engahluziwe nensimbi, okufanayo ngezansi) ukukhiqizwa ngo-2017 no-2018, futhi ngenxa yempumelelo enkulu yamakhulu ezigidi zamathani okunciphisa umthamo wensimbi, ukusetshenziswa kwamandla ensimbi yaseChina. izinga kufanele ngabe lithuthukisiwe kakhulu, futhi isikhala sokuthuthuka sincishiswa kakhulu.
Isigaba esingenalutho esingunxande we-Yuantaiinekhwalithi enhle, izindleko eziphansi, ukulethwa okusheshayo.Siyakwamukela wonke umuntu axhumane nathi futhi a-ode.Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltdinamalungelo obunikazi angama-80, Inemigqa yokukhiqiza engama-72 futhi inikeze ngemikhiqizo yamapayipi ensimbi kumaphrojekthi amakhulu angaphezu kuka-1400 ekhaya naphesheya. Isibonelo, i-Bird's Nest, i-National Grand Theatre, izindawo ze-Qatar World Cup, kanye ne-Egypt Million Feydan Land Improvement Project.
