Esikhathini samanje sentuthuko esheshayo embonini yokwakha nengqalasizinda, izixazululo zamapayipi ezinokwethenjelwa nezihlala isikhathi eside ziye zaba yisihluthulelo sempumelelo yephrojekthi. Njengomkhiqizi ohamba phambili wamapayipi ensimbi ajikelezayo kanye nemikhiqizo yokumboza amapayipi eShayina, iCangzhou Spiral Steel Pipes Group Co., Ltd. yethuleIpayipi Lomugqa we-X70 SSAW, okuchaza isizukulwane esisha sezindinganiso zeLine Pipe ngokusebenza kwayo okuvelele.
Ipayipi le-X70 liwumkhiqizo oyinhloko wensimbi yepayipi yezinga eliphezulu, enamandla okukhiqiza angaphezu kuka-485 MPa, enamathela ezindinganisweni eziqinile njenge-API 5L kanye ne-GB/T 9711. Lihlanganisa amandla aphezulu nokuqina okuhle kakhulu futhi lingabhekana kalula nezinselele eziningi ezifana nokucindezela okuphezulu kanye nokugqwala ekufakweni komhlaba. Lisebenzisa inqubo yokuwelda ye-arc engaphansi komhlaba ethuthukisiwe (SSAW), lapho umugqa wensimbi ugoqwa khona bese ushintshwa. Ukucindezeleka kokushintshwa kusatshalaliswa ngokulinganayo, okunikeza ipayipi amandla angavamile okucindezela kanye nokumelana nokugqwala, ikakhulukazi afanelekela amapayipi egesi angaphansi komhlaba, ubunjiniyela besisekelo, kanye nezinye izimo ezibalulekile. Imininingwane yomkhiqizo isukela ku-219mm kuya ku-3500mm, enobude obubodwa obufika kumamitha angu-35, ehlangabezana kahle nezidingo zengqalasizinda enkulu ehlukahlukene kanye nezicelo ezikhethekile.
Ngokusekelwe ekuqongeleleni kobuchwepheshe kusukela yasungulwa ngo-1993, i-Cangzhou Spiral Steel Pipes Group Co., Ltd. iyinkampani enamandla: ifektri yayo ihlanganisa indawo engamamitha-skwele angu-350,000, enempahla eyizigidi ezingu-680 zama-yuan, futhi inabasebenzi abangu-680. Amandla ayo okukhiqiza minyaka yonke amapayipi ensimbi ajikelezayo afinyelela amathani angu-400,000, ngenani lokukhiqiza lonyaka elingama-yuan ayizigidi eziyizinkulungwane ezingu-1.8. Le nkampani ilawula ngokuqinile yonke inqubo kusukela ekukhetheni izinto zokusetshenziswa kuya ekuhlolweni komkhiqizo, yenza izivivinyo eziningi ezifana nokuhlolwa kwe-radiographic kanye nokutholwa kwamaphutha e-ultrasonic ukuqinisekisa impilo yenkonzo ehlala isikhathi eside kanye nokusebenza okuzinzile. Njengesixazululo se-Line Pipe esihlanganisa ikhwalithi kanye nokuguquguquka, i-X70 SSAWIpayipi Lomugqaayifanele nje kuphela ukuthuthwa kwegesi namanzi ngaphansi komhlaba, kodwa futhi isebenza kahle ezimweni zokufakwa kwamapayipi amabanga amade kanye nokudluliselwa koketshezi lwezimboni, iba ukukhetha okuthembekile kwamaphrojekthi engqalasizinda yomhlaba wonke.
