Emakethe yamanje yamapayipi ensimbi, kukholakala ukuthi ungakwazi njalo ukuthola imikhiqizo oyifunayo njengoba kunezinhlobo eziningi zamapayipi ensimbi atholakalayo ukuze asetshenziswe ezinhlelweni ezihlukahlukene. Ipayipi elishiselwe litholakala kabanzi futhi liyathengeka, ngakho liba yisinqumo esidumile kumaphrojekthi amakhulu kakhulu njengamapayipi. Ngokuphambene, ipayipi yensimbi engagqwali yenziwe nge-alloy yensimbi ne-chromium, futhi ingenye yezinhlobo zamapayipi ezibiza kakhulu emakethe. Ngokuvamile, ipayipi lensimbi elihlanganisiwe lingahlukaniswa ngezigaba ezihlukahlukene njengokucaciswa okuqondile kanye nezicelo ezahlukene. Ekukhiqizeni ipayipi langempela, abakhiqizi bepayipi lensimbi ngokuvamile bavame ukuqinisekisa ngokuphindaphindiwe izidingo ezithile zamapayipi kusengaphambili ngokusho kwe-oda, okubandakanya ukushuba kodonga, ubude, ububanzi nokunye. izidingo zezicelo zangempela.
Namuhla, amapayipi ashiselwe asetshenziswa kabanzi ekusetshenzisweni okuhlukahlukene. Okokuqala, esinye sezici eziyinhloko zensimbi ehlanganisiwe yizinqubo zayo zokukhiqiza ezingeyona inkimbinkimbi, enekhono elikhulu lokukhiqiza, ukuze kwandiswe izidingo emakethe yensimbi. Ngakolunye uhlangothi, ngenxa yezindleko eziphansi zokukhiqiza, intengo yepayipi yensimbi ayiphezulu kakhulu, okuyisizathu esisodwa esikhulu seningi lezinhloso zangempela. Ngenxa yobuchwepheshe obuhlukile bokucubungula, ipayipi elihlanganisiwe le-seam eliqondile ngokuvamile lihlukaniswe ngezigaba ezimbili ezinkulu: ipayipi le-ERW nepayipi le-LSAW. Kusukela ekubunjweni kwepayipi, kunezigaba ezimbili ezivamile: ipayipi yensimbi eyindilinga kanye nepayipi yensimbi yesikwele. Ekuthengeni kwangempela, amakhasimende angakhetha izinhlobo ezithile zamapayipi ngokwezidingo zawo zangempela. Ngenxa yentengo yayo yokuthengisa evumayo kanye nohlu olubanzi lwezinkambu zokufaka isicelo, ipayipi elishiselwe selidume kakhulu phakathi kwabantu ngezinjongo zangempela ezihlukahlukene.
Ngokuthuthuka kwesimanje kuzwelonke kanye nentuthuko eqhubekayo yomphakathi, imboni yezokwakha eChina ibilokhu idlondlobala eminyakeni yamuva. Ipayipi lensimbi elishiselwe, njengenye yezinto ezibalulekile zokwakha, seliyingxenye ebalulekile yokukhiqiza nokuphila. Ngomqondo othile, kulungele kakhulu ukuthengwa kwethu kwangempela kanye nomphumela wokufaka isicelo, uma sinolwazi oluthe xaxa lobuchwepheshe lwamapayipi ashiselwe. Njengoba isisho esihle sihamba, isayensi nobuchwepheshe kungamandla ayinhloko okukhiqiza. Ngeke kuphikwe ukuthi kuhlale kuyindlela ende kunoma iyiphi inkampani yamapayipi ukuzuza ukuphila isikhathi eside kanye nentuthuko eyengeziwe esikhathini esizayo.
Thumela umlayezo wakho kithi:
