NgoSepthemba, iChina neRussia basayina isivumelwano sepayipi legesi yemvelo laseSiberia-2. Ipayipi, elizokwakhiwa eMongolia, lihlose ukuhlinzeka ngegesi yemvelo evela ezindaweni zasentshonalanga yeRussia ukuya e-China. Ngomthamo oklanyelwe wonyaka wokudlulisa wama-cubic metres ayizigidi eziyizinkulungwane ezingama-50, kulindeleke ukuthi isebenze cishe ngo-2030.
Amandla aseSiberia-2 angaphezulu nje kwepayipi lamandla; iyinsika yamasu yokulungisa kabusha ukuhleleka komhlaba. Kubukela phansi i-Western energy hegemony, kujulisa ukubambisana kwamasu phakathi kweChina neRussia, futhi kuqinise ubungqabavu bomnotho besifunda. Iphinde inikeze isibonelo esisebenzayo sokubambisana ngokuwina-win emhlabeni jikelele. Naphezu kokubhekana nezinselele eziningi zobuchwepheshe, i-geopolitical, kanye nemvelo, inani lesu lephrojekthi leqa imingcele yezohwebo, libe iphrojekthi eyingqophamlando ekuthuthukiseni ukwakhiwa komphakathi onekusasa elabiwe lesintu. Njengoba uPutin esho emcimbini wokusayina, "Lelipayipi lizohlanganisa ikusasa lethu."
Njengenkampani yohwebo lwangaphandle esebenza ngamapayipi kawoyela nensimbi ekhethekile, iRoyal Steel Group ibambe iqhaza ngokujulile kuphrojekthi yepayipi legesi yemvelo "Amandla eSiberia 2", kuyilapho futhi isekela ukubambisana kwamandla nezinqubomgomo zokuthuthukiswa kwesifunda phakathi kweChina, iRussia, neMongolia.
Insimbi ye-X80 iwuphawu lokuma kwensimbi yepayipi lamandla aphezulu, ethobelana nezinga le-API 5L 47th edition. Inikeza amandla amancane okukhiqiza angu-552 MPa, amandla aqinile angu-621-827 MPa, kanye nesilinganiso sokuvunwa kuya kumandla esingu-0.85 noma ngaphansi. Izinzuzo zayo eziyinhloko ilele ekwakhiweni okungasindi, ukuqina okuhle kakhulu, kanye nokushisela okulungiselelwe.
Izinhlelo zokusebenza ezijwayelekile zifaka:
Ipayipi Legesi Yemvelo Yase-China-Russia East Line: Isebenzisa i-X80 steel kuyo yonke indawo, ihambisa i-cubic metres yegesi engu-38 billion njalo ngonyaka futhi inqamula i-permafrost nezindawo ezinyakazayo, ibeka uphawu lomhlaba wonke lobuchwepheshe bokwakha amapayipi ogwini.
I-West-East Gas Pipeline III Project: Amapayipi ensimbi angu-X80 ahlanganisa ngaphezu kuka-80% wengqikithi yokusetshenziswa, esekela ukuthuthwa kwegesi yemvelo ngendlela efanele isuka entshonalanga yeChina iye esifundeni saseYangtze River Delta.
Ukuthuthukiswa kwamafutha kanye negesi ajulile: Kuphrojekthi yensimu yegesi ye-Liwan 3-1 eSouth China Sea, amapayipi ensimbi angenamthungo angu-X80 asetshenziselwa amapayipi angaphansi kolwandle ekujuleni kwamanzi angaphezu kwamamitha angu-1,500, anamandla okucindezela angaphandle angama-35 MPa.
Insimbi ye-X90 imele isizukulwane sesithathu sezinsimbi zamapayipi anamandla aphezulu, ezithobelana nezinga le-API 5L 47th edition. Inamandla amancane okukhiqiza angu-621 MPa, amandla e-tensile angu-758-931 MPa, kanye ne-carbon equivalent (Ceq) engu-0.47% noma ngaphansi. Izinzuzo zayo eziyinhloko zifaka ukugcinwa kwamandla aphezulu, i-breakthrough weldability, kanye nokuguquguquka kwezinga lokushisa eliphansi.
Izimo ezijwayelekile zohlelo lokusebenza zihlanganisa:
Amandla aseSiberia 2 Pipeline: Njengento ewumgogodla wephrojekthi, ipayipi lensimbi le-X90 lizothutha igesi ibanga elide lisuka ezizindeni zegesi zaseRussia eziseNtshonalanga yeSiberia liya eNyakatho neChina. Lapho iqala ukusebenza ngo-2030, umthamo wonyaka wokudluliswa kwegesi kulindeleke ukuthi uhlanganise ngaphezu kuka-20% wesamba sesamba segesi yamapayipi ephuma eChina.
I-Central Asia Natural Gas Pipeline Line D: Ezindaweni zenhlabathi enosawoti omningi yesigaba se-Uzbek, ipayipi lensimbi le-X90, elihlanganiswe nesistimu yokuvikela i-cathodic ye-3PE +, inesikhathi sokusebenza kwayo esinwetshwe iminyaka engu-50.
I-3PE coating iqukethe i-epoxy powder coating (FBE) primer, ungqimba olumaphakathi olunamathelayo, kanye ne-polyethylene (PE) topcoat, enogqinsi oluphelele ≥2.8mm, okwenza uhlelo lokuvikela oluyinhlanganisela "oluqinile + oluguquguqukayo":
Isendlalelo sesisekelo se-FBE, esinogqinsi luka-60-100μm, amabhondi ngamakhemikhali endaweni yepayipi lensimbi, enikeza ukunamathela okuhle kakhulu (≥5MPa) nokumelana nokunqanyulwa kwe-cathodic (irediyasi yepeel ≤8mm ku-65°C/48h).
I-Adhesive emaphakathi: 200-400μm obukhulu, eyenziwe nge-resin ye-EVA eguquliwe, ibambene ngokomzimba ne-FBE ne-PE, ngamandla ekhasi angu-≥50N/cm ukuvimbela ukuhlukaniswa kwe-interlayer.
I-PE yangaphandle: ≥2.5mm ugqinsi, eyenziwe nge-polyethylene ephezulu-density (HDPE), enephuzu lokuthambisa le-Vicat ≥110°C kanye nokumelana nokuguga kwe-UV okufakazelwe ukuhlolwa kwesibani se-xenon arc samahora angu-336 (ukugcinwa kwamandla aqinile ≥80%). Ifanele ukusetshenziswa ezindaweni ezinotshani zaseMongolia nasezindaweni ezineqhwa.
I-Royal Steel Group, nomsebenzi wayo "we-Material Innovation Driving the Energy Revolution," iyaqhubeka nokuhlinzeka ngemikhiqizo yamapayipi ensimbi esebenza kahle kakhulu, ethembeke kakhulu kanye nezinsizakalo zobuchwepheshe zokwakhiwa kwengqalasizinda yamandla emhlabeni jikelele.
