NgoSeptemba, iTshayina neRashiya batyikitye isivumelwano sombhobho wegesi yendalo iPower of Siberia-2. Lo mbhobho, oza kwakhiwa ngeMongolia, ujolise ekunikezeleni igesi yendalo evela kumasimi egesi asentshona eRashiya ukuya eTshayina. Njengoko umbane wonyaka olungiselelweyo ufikelela kwiibhiliyoni ezingama-50 zeemitha zeekyubhiki, kulindeleke ukuba usebenze malunga nowama-2030.
Amandla eSiberia-2 angaphezulu nje kombhobho wamandla; sisixhobo esibalulekileyo sokwakha ngokutsha inkqubo yehlabathi. Atshabalalisa ulawulo lwamandla aseNtshona, aqinisa intsebenziswano enobuchule phakathi kweTshayina neRashiya, kwaye avuselela amandla oqoqosho lwengingqi. Ikwabonelela ngomzekelo osebenzayo wentsebenziswano ephumelelayo kwihlabathi elinamacala amaninzi. Nangona ijongene nemingeni emininzi yobuchwephesha, yezopolitiko, kunye neyendalo, ixabiso lesicwangciso leprojekthi lidlula imida yezorhwebo, libe yiprojekthi ebalulekileyo ekukhuthazeni ukwakhiwa koluntu olunekamva elilinganayo loluntu. Njengoko uPutin watshoyo kumsitho wokutyikitya, "Lo mbhobho uza kubopha ikamva lethu kunye."
Njengenkampani yorhwebo lwangaphandle egxile kwimibhobho yeoyile kunye nentsimbi ekhethekileyo, iRoyal Steel Group ibandakanyeka kakhulu kwiprojekthi yemibhobho yegesi yendalo ethi "Power of Siberia 2", ngelixa ikwaxhasa intsebenziswano yamandla kunye nemigaqo-nkqubo yophuhliso lwengingqi phakathi kweTshayina, iRashiya, neMongolia.
Intsimbi ye-X80 yindlela efanelekileyo yokulinganisa intsimbi yombhobho enamandla aphezulu, ihambelana nomgangatho we-API 5L 47th edition. Inika amandla okuvelisa ubuncinane be-552 MPa, amandla okutsalwa kwe-621-827 MPa, kunye nomlinganiselo wokuvelisa amandla we-0.85 okanye ngaphantsi. Iingenelo zayo eziphambili zikwindlela elula yoyilo, ukuqina okugqwesileyo, kunye nokudityaniswa kakuhle.
Izicelo eziqhelekileyo ziquka:
Umbhobho wegesi yendalo ophakathi kweTshayina neRashiya eMpuma: Isebenzisa intsimbi ye-X80 kuyo yonke indawo, ithumela igesi eyi-38 yeebhiliyoni zeemitha zeekyubhikhi ngonyaka kwaye idlula kwiindawo ezibandayo kunye neendawo ezisebenza ngokwenyikima, ibeka umlinganiselo wehlabathi jikelele wetekhnoloji yokwakha imibhobho engaselunxwemeni.
Iprojekthi yePipeline III yeGesi eNtshona-Mpuma: Imibhobho yentsimbi ye-X80 ithatha ngaphezulu kwe-80% yokusetyenziswa kwayo yonke, ixhasa ukuthuthwa kwegesi yendalo ngendlela efanelekileyo ukusuka entshona yeTshayina ukuya kummandla weYangtze River Delta.
Uphuhliso lweoyile kunye negesi emanzini anzulu: Kwiprojekthi yentsimi yegesi yeLiwan 3-1 kuLwandle lwaseSouth China, imibhobho yentsimbi engenamthungo ye-X80 isetyenziselwa imibhobho yamanzi angaphantsi komhlaba kubunzulu bamanzi obungaphezulu kweemitha ezili-1,500, kunye namandla angaphandle okucinezelwa angama-35 MPa.
Intsimbi ye-X90 imele isizukulwana sesithathu seentsimbi zepayipi ezinamandla aphezulu, ezihambelana nomgangatho we-API 5L 47th edition. Inamandla okuvelisa ubuncinci be-621 MPa, amandla okutsalwa angama-758-931 MPa, kunye ne-carbon equivalent (Ceq) engama-0.47% okanye ngaphantsi. Iingenelo zayo eziphambili ziquka amandla aphezulu okugcina, ukuwelda okuphuphumayo, kunye nokuzivumelanisa nobushushu obuphantsi.
Iimeko eziqhelekileyo zokusetyenziswa ziquka:
Amandla eSiberia 2 Pipeline: Njengezinto eziphambili zeprojekthi, umbhobho wentsimbi we-X90 uza kuthwala uthutho lwegesi oluhamba umgama omde ukusuka kumasimi egesi aseNtshona Siberia aseRashiya ukuya eMntla China. Xa uqaliswa ukusebenza ngo-2030, umthamo wonyaka wothutho lwegesi kulindeleke ukuba ube ngaphezulu kwe-20% yegesi iyonke engeniswa eTshayina.
Umbhobho weGesi yendalo eMbindi Asia D: Kwiindawo ezinomhlaba onetyuwa eninzi kwicandelo lase-Uzbek, umbhobho wentsimbi we-X90, odityaniswe nenkqubo yokukhusela i-3PE + cathodic, ubomi bawo benkonzo buya kwandiswa ukuya kwiminyaka engama-50.
Ingubo ye-3PE ine-primer ye-epoxy powder coating (FBE), umaleko ophakathi onamathelayo, kunye ne-topcoat ye-polyethylene (PE), enobukhulu obupheleleyo be-≥2.8mm, eyenza inkqubo yokukhusela edibeneyo "eqinileyo neguquguqukayo":
Umaleko wesiseko se-FBE, onobukhulu obuyi-60-100μm, ubopha ngokweekhemikhali kumphezulu wombhobho wentsimbi, ubonelela ngokunamathela okugqwesileyo (≥5MPa) kunye nokumelana nokuqhekeka kwe-cathodic (i-reyidiyasi ye-peel ≤8mm kwi-65°C/48h).
Isincamathelisi esiPhakathi: Ubukhulu obuyi-200-400μm, esenziwe nge-resin ye-EVA eguquliweyo, sibambene ngokwasemzimbeni ne-FBE kunye ne-PE, sinamandla okuxobuka angama-≥50N/cm ukuthintela ukwahlukana kweeleya eziphakathi.
I-PE yangaphandle: ≥2.5mm ubukhulu, yenziwe nge-polyethylene enoxinano oluphezulu (i-HDPE), kunye nendawo yokuthambisa yeVicat ≥110°C kunye nokumelana nokuguga kwe-UV okubonakaliswe luvavanyo lwesibane se-xenon arc esisebenza iiyure ezingama-336 (ukugcinwa kwamandla okutsalwa ≥80%). Ifanelekile ukusetyenziswa kwiindawo ezinengca zaseMongolia nakwiindawo ezihlala iqhwa.
I-Royal Steel Group, enomgomo wayo othi "Izinto Ezintsha Eziqhuba Uguquko Lwamandla," iyaqhubeka nokubonelela ngeemveliso zemibhobho yentsimbi esebenza kakuhle, ethembekileyo kakhulu kunye neenkonzo zobugcisa zokwakha iziseko zophuhliso zamandla kwihlabathi liphela.
