NgoSeptemba, iChina kunye neRashiya basayine isivumelwano soMbhobho wegesi wendalo weSiberia-2. Lo mbhobho, oza kwakhiwa ngeMongolia, ujolise ekuboneleleni ngerhasi yendalo esuka kwimimandla yasentshona yaseRussia ukuya eTshayina. Ngomthamo oyilelweyo wonyaka wothumelo ozibhiliyoni ezingama-50 zetyhubhic metres, kulindeleke ukuba isebenze malunga nowama-2030.
Amandla aseSiberia-2 angaphezulu nje kombhobho wamandla; sisiphatho sobuchule sokwenza ngokutsha ulungelelwaniso lwehlabathi. Ijongela phantsi i-hegemony yamandla aseNtshona, yenza nzulu intsebenziswano phakathi kweTshayina neRussia, kwaye ivuselela amandla oqoqosho lwengingqi. Ikwabonelela ngomzekelo osebenzayo wokuphumelela-wokuphumelela intsebenziswano kwihlabathi lezizwe ngezizwe. Ngaphandle kokujongana nemiceli mngeni emininzi yobugcisa, i-geopolitical, kunye ne-ikholoji, ixabiso leqhinga leprojekthi lidlula imida yorhwebo, libe yiprojekthi ebalulekileyo ekukhuthazeni ukwakhiwa koluntu olunekamva ekwabelwana ngalo kuluntu. Njengoko uPutin watsho kumsitho wokutyikitya, "Lo mbhobho uya kuhlanganisa ikamva lethu kunye."
Njengenkampani yokurhweba kumazwe angaphandle egxile kwimibhobho yeoli kunye nentsimbi ekhethekileyo, iRoyal Steel Group ibandakanyeka ngokunzulu kwiprojekthi yombhobho wegesi yendalo "Amandla eSiberia 2", ngelixa ikwaxhasa intsebenziswano yamandla kunye nemigaqo-nkqubo yophuhliso lwengingqi phakathi kweTshayina, iRashiya neMongolia.
Insimbi ye-X80 yibhentshi yentsimbi yombhobho ophezulu, ehambelana ne-API 5L 47th edition standard. Inika ubuncinci amandla esivuno se-552 MPa, amandla okuqina angama-621-827 MPa, kunye nomlinganiselo wokuvunwa kwe-0.85 okanye ngaphantsi. Iingenelo zayo eziphambili zilele kuyilo olukhaphukhaphu, ukuqina okugqwesileyo, kunye ne-weldability ephuculweyo.
Usetyenziso oluqhelekileyo lubandakanya:
Umbhobho weGesi yeNdalo yaseTshayina-eRashiya: Isebenzisa i-X80 yentsimbi kuyo yonke indawo, ihambisa i-38 yebhiliyoni ye-cubic metres yerhasi ngonyaka kwaye inqumla kwi-permafrost kunye nemimandla esebenza ngokushukumayo, imisela umgangatho wehlabathi wokwakhiwa kwemibhobho elunxwemeni.
IProjekthi yoMbhobho weGesi weNtshona-Mpuma we-III: Imibhobho yentsimbi ye-X80 ithatha ngaphezulu kwe-80% yosetyenziso lulonke, ixhasa uthutho olusebenzayo lwerhasi yendalo ukusuka entshona China ukuya kwingingqi yeDelta yoMlambo iYangtze.
Uphuhliso lwamanzi anzulu kunye negesi: Kwiprojekthi yegesi ye-Liwan 3-1 kwi-South China Sea, i-X80 imibhobho yentsimbi engenamthungo isetyenziselwa imibhobho ye-submarine kubunzulu bamanzi obudlula i-1,500 yeemitha, kunye namandla angaphandle oxinzelelo lwe-35 MPa.
I-X90 yensimbi imele isizukulwana sesithathu semibhobho yentsimbi ephezulu, ehambelana ne-API 5L 47th edition standard. Inomlinganiselo omncinci wokuvelisa amandla we-621 MPa, i-tensile yamandla ye-758-931 MPa, kunye ne-carbon equivalent (Ceq) ye-0.47% okanye ngaphantsi. Iinzuzo zayo eziphambili zibandakanya amandla aphezulu okugcina amandla, i-weldability ye-weldability, kunye nokuguquguquka kobushushu obuphantsi.
Iimeko zesicelo eziqhelekileyo ziquka:
Amandla eSiberia 2 Pipeline: Njengeyona nto ingundoqo yeprojekthi, umbhobho we-X90 wensimbi uya kuqhuba ukuthuthwa kwegesi okude ukusuka kwiindawo zegesi eNtshona yeSiberia ukuya eMntla China. Ekuqaliseni ukusebenza ngo-2030, umthamo wonyaka wothunyelo lwerhasi kulindeleke ukuba uphendule ngaphezulu kwe-20% yegesi ephuma ngaphandle eTshayina.
UMbindi weAsia weGesi yeNdalo uMbhobho weMibhobho ye-D: Kwimimandla yomhlaba we-saline kakhulu yecandelo le-Uzbek, ipayipi yensimbi ye-X90, idibene ne-3PE + inkqubo yokukhusela i-cathodic, inobomi bayo benkonzo eyandiswe kwiminyaka eyi-50.
Ingubo ye-3PE iqukethe i-epoxy powder coating (FBE) primer, i-adhesive intermediate layer, kunye ne-polyethylene (PE) topcoat, kunye nobukhulu obupheleleyo ≥2.8mm, eyenza "i-rigid + flexible" inkqubo yokukhusela edibeneyo:
Uluhlu lwesiseko se-FBE, kunye nobukhulu be-60-100μm, iibhondi zekhemikhali kumbhobho wensimbi, ukubonelela ngokunamathela okugqwesileyo (≥5MPa) kunye nokuxhatshazwa kwe-cathodic disbondment (i-peel radius ≤8mm kwi-65 ° C / 48h).
I-Adhesive Intermediate: 200-400μm ubukhulu, eyenziwe nge-resin ye-EVA eguquliweyo, idibanisa ngokwasemzimbeni kunye ne-FBE kunye ne-PE, inamandla e-peel ≥50N / cm ukukhusela ukuhlukana kwe-interlayer.
I-PE yangaphandle: ≥2.5mm ubukhulu, eyenziwe nge-polyethylene ephezulu (i-HDPE), ene-Vicat softening point ≥110 ° C kunye nokumelana nokuguga kwe-UV kubonakaliswe yi-336-yure ye-xenon arc test yesibane (ukugcinwa kwamandla e-tensile ≥80%). Ilungele ukusetyenziswa kwiindawo ezinengca zaseMongolia kunye neendawo ezihlala i-permafrost.
Iqela leRoyal Steel, kunye nomsebenzi walo we "Material Innovation Driving the Energy Revolution," iyaqhubeka nokubonelela ngokusebenza okuphezulu, iimveliso zemibhobho yentsimbi ethembekileyo kakhulu kunye neenkonzo zobugcisa kulwakhiwo lweziseko zombane zehlabathi.
