Izindaba - IShayina neRussia basayine isivumelwano sombhobho wegesi yemvelo iPower of Siberia-2. IRoyal Steel Group iveze ukuzimisela kwayo ukusekela ngokugcwele intuthuko yezwe.

NgoSepthemba, iShayina neRussia basayina isivumelwano sepayipi legesi yemvelo iPower of Siberia-2. Leli payipi, elizokwakhiwa ngeMongolia, lihlose ukuhlinzeka ngegesi yemvelo evela emasimini egesi asentshonalanga yeRussia iye eShayina. Njengoba linomthamo wokudlulisa waminyaka yonke oklanyelwe ama-cubic metres ayizigidigidi ezingama-50, kulindeleke ukuthi lisebenze cishe ngo-2030.

Amandla eSiberia-2 angaphezulu nje komzila wamandla; ayisivikelo samasu sokwakha kabusha uhlelo lomhlaba wonke. Acekela phansi ubukhosi bamandla baseNtshonalanga, ajulisa ukubambisana kwamasu phakathi kweShayina neRussia, futhi aqinise amandla omnotho wesifunda. Aphinde anikeze isibonelo esisebenzayo sokubambisana okuzuzayo kuwo wonke umuntu ezweni elinabantu abaningi. Naphezu kokubhekana nezinselele eziningi zobuchwepheshe, zezwe, kanye nezemvelo, inani lamasu lephrojekthi lidlula imingcele yezentengiselwano, libe yiphrojekthi ebalulekile ekukhuthazeni ukwakhiwa komphakathi onekusasa elihlanganyelwe lesintu. Njengoba uPutin eshilo emcimbini wokusayina, "Lo mzila uzohlanganisa ikusasa lethu ndawonye."

Njengenkampani yezohwebo lwangaphandle egxile kumapayipi kawoyela kanye nensimbi ekhethekile, iRoyal Steel Group ihileleke kakhulu kuphrojekthi yepayipi legesi yemvelo ethi "Power of Siberia 2", kuyilapho futhi isekela ukubambisana kwamandla kanye nezinqubomgomo zokuthuthukiswa kwesifunda phakathi kweShayina, iRussia, neMongolia.

Amapayipi amathathu ensimbi yekhabhoni enobubanzi obukhulu ahlanganisiwe amnyama ahlanganisiwe

I-Royal Steel Group ingahlinzeka ngamapayipi ensimbi e-API 5L X80, API 5L X90, kanye ne-3PE.

Insimbi ye-X80 iyisilinganiso sensimbi yamapayipi enamandla aphezulu, ihambisana nezinga le-API 5L 47th edition. Inikeza amandla okukhiqiza okungenani angu-552 MPa, amandla okudonsa angu-621-827 MPa, kanye nesilinganiso sokukhiqiza amandla esingu-0.85 noma ngaphansi. Izinzuzo zayo eziyinhloko zisekuklanyweni okulula, ukuqina okuhle kakhulu, kanye nokushibilika okulungiselelwe.

Izinhlelo zokusebenza ezijwayelekile zifaka:
Ipayipi Legesi Yemvelo Eliphakathi Kwe-China ne-Russia East Line: Isebenzisa insimbi ye-X80 kuyo yonke indawo, idlulisa igesi engama-cubic metres ayizigidigidi ezingu-38 minyaka yonke futhi idlula ezindaweni ezihlala iqhwa kanye nezindawo ezisebenza ngokuzamazama komhlaba, ibeka uphawu lomhlaba wonke lobuchwepheshe bokwakhiwa kwamapayipi ogwini.

Iphrojekthi Yepayipi Legesi LeNtshonalanga-Mpumalanga IIIAmapayipi ensimbi e-X80 aqukethe ngaphezu kuka-80% wokusetshenziswa okuphelele, okusekela ukuthuthwa kwegesi yemvelo okuphumelelayo kusuka entshonalanga yeShayina kuya esifundeni saseYangtze River Delta.
Ukuthuthukiswa kukawoyela negesi emanzini ajulile: Kuphrojekthi yensimu yegesi iLiwan 3-1 eSouth China Sea, amapayipi ensimbi angenamthungo e-X80 asetshenziselwa amapayipi angaphansi kwamanzi ekujuleni kwamanzi okungaphezu kwamamitha ayi-1,500, ngamandla angaphandle okucindezela angu-35 MPa.

Insimbi ye-X90 imele isizukulwane sesithathu sezinsimbi zamapayipi ezinamandla aphezulu, ezihambisana nezinga le-API 5L 47th edition. Inamandla okukhiqiza okungenani angu-621 MPa, amandla okuthamba angu-758-931 MPa, kanye ne-carbon equivalent (Ceq) engu-0.47% noma ngaphansi. Izinzuzo zayo eziyinhloko zifaka phakathi amandla okugcina aphezulu, ukushibilika okuphumelelayo, kanye nokuzivumelanisa nezimo eziphansi zokushisa.

Amacala ajwayelekile okusetshenziswa afaka:

Amandla eSiberia 2 Pipeline: Njengezinto eziyinhloko zalo msebenzi, ipayipi lensimbi le-X90 lizothutha igesi ibanga elide lisuka emasimini egesi aseNtshonalanga Siberia eRussia liye eNyakatho China. Lapho liqala ukusebenza ngo-2030, umthamo wonyaka wokudlulisa igesi kulindeleke ukuthi uhlanganise ngaphezu kwama-20% egesi ethunyelwa yiChina iyonke.

Umzila Wepayipi Legesi Yemvelo Ephakathi E-Asia D: Ezindaweni ezinenhlabathi enosawoti omningi engxenyeni yase-Uzbek, ipayipi lensimbi le-X90, elihlanganiswe nohlelo lokuvikela lwe-3PE + cathodic, linempilo yalo yokusebenza enwetshiwe ibe yiminyaka engama-50.

Isembozo se-3PE siqukethe i-primer ye-epoxy powder coating (FBE), ungqimba oluphakathi olunamathelayo, kanye ne-topcoat ye-polyethylene (PE), enobukhulu obuphelele obungu-≥2.8mm, okwakha uhlelo lokuvikela oluhlanganisiwe "oluqinile + oluguquguqukayo":

Isendlalelo sesisekelo se-FBE, esinobukhulu obungu-60-100μm, sibopha ngamakhemikhali ebusweni bepayipi lensimbi, sihlinzeka ngokunamathela okuhle kakhulu (≥5MPa) kanye nokumelana nokuqhekeka kwe-cathodic (i-reyidi ye-peel ≤8mm ku-65°C/48h).

I-Adhesive Ephakathi: Ubukhulu obungu-200-400μm, eyenziwe nge-resin ye-EVA eguquliwe, ihlangana ne-FBE kanye ne-PE, enamandla okuxebuka angu-≥50N/cm ukuvimbela ukuhlukaniswa kwezingqimba.
I-PE yangaphandle: ≥2.5mm ubukhulu, yenziwe nge-polyethylene enobukhulu obuphezulu (i-HDPE), enephuzu lokuthambisa le-Vicat ≥110°C kanye nokumelana nokuguga kwe-UV okuqinisekiswe ukuhlolwa kwesibani se-xenon arc samahora angu-336 (ukugcinwa kwamandla okudonsa ≥80%). Ifanele ukusetshenziswa ezindaweni ezinotshani zaseMongolia nasezindaweni ezihlala iqhwa.

I-Royal Steel Group, ngenhloso yayo ethi "Ukusungula Izinto Ezintsha Ukuqhuba Inguquko Yamandla," iyaqhubeka nokuhlinzeka ngemikhiqizo yamapayipi ensimbi esebenza kahle kakhulu, ethembeke kakhulu kanye nezinsizakalo zobuchwepheshe zokwakha ingqalasizinda yamandla emhlabeni jikelele.
