Nkhani - China ndi Russia asayina mgwirizano wa payipi ya gasi lachilengedwe ya Power of Siberia-2. Royal Steel Group yawonetsa kufunitsitsa kwake kuthandizira chitukuko cha dzikolo.

Mu Seputembala, China ndi Russia adasaina pangano la payipi ya gasi lachilengedwe ya Power of Siberia-2. Paipiyi, yomwe imangidwa kudzera ku Mongolia, ikufuna kupereka gasi wachilengedwe kuchokera ku minda ya gasi yakumadzulo kwa Russia kupita ku China. Ndi mphamvu yotumizira gasi ya pachaka yokwana 50 biliyoni cubic metres, ikuyembekezeka kugwira ntchito pafupifupi chaka cha 2030.

Mphamvu ya Siberia-2 si njira yongogwiritsa ntchito mphamvu zokha; ndi njira yothandiza kwambiri yokonzanso dongosolo lapadziko lonse lapansi. Imafooketsa ulamuliro wa mphamvu za kumadzulo, imakulitsa mgwirizano pakati pa China ndi Russia, komanso imalimbitsa mphamvu zachuma za m'chigawo. Imaperekanso chitsanzo chothandiza cha mgwirizano wopindulitsa aliyense m'dziko lokhala ndi madera ambiri. Ngakhale kuti ikukumana ndi mavuto ambiri aukadaulo, ndale, komanso zachilengedwe, phindu la polojekitiyi limadutsa malire amalonda, kukhala pulojekiti yofunika kwambiri polimbikitsa kumanga gulu lomwe lili ndi tsogolo logawana la anthu. Monga momwe Putin adanenera pamwambo wosainira, "Njira iyi igwirizanitsa tsogolo lathu."

Monga kampani yogulitsa zinthu zakunja yomwe imagwira ntchito kwambiri pa mapaipi amafuta ndi zitsulo zapadera, Royal Steel Group ikugwira ntchito kwambiri mu pulojekiti ya mapaipi a gasi lachilengedwe ya "Power of Siberia 2", komanso kuthandizira mgwirizano wa mphamvu ndi mfundo zachitukuko pakati pa China, Russia, ndi Mongolia.

Mapaipi atatu akuda olumikizidwa ndi chitsulo chachikulu cha kaboni m'mimba mwake

Royal Steel Group ingapereke mapaipi achitsulo a API 5L X80, API 5L X90, ndi 3PE.

Chitsulo cha X80 ndi muyezo wa chitsulo cha mapaipi champhamvu kwambiri, mogwirizana ndi muyezo wa API 5L 47th edition. Chimapereka mphamvu yocheperako ya 552 MPa, mphamvu yokoka ya 621-827 MPa, ndi chiŵerengero cha mphamvu yogoletsa cha 0.85 kapena kuchepera. Ubwino wake waukulu uli mu kapangidwe kopepuka, kulimba kwabwino, komanso kusinthasintha bwino.

Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo:
Paipi ya Gasi Yachilengedwe ya China-Russia East LinePogwiritsa ntchito chitsulo cha X80, chimatumiza mpweya wokwana ma kiyubiki mita 38 biliyoni pachaka ndipo chimadutsa m'malo ozizira komanso omwe ali ndi mphamvu zowononga chilengedwe, ndikuyika chizindikiro chapadziko lonse cha ukadaulo womanga mapaipi a m'mphepete mwa nyanja.

Pulojekiti ya West-East Gas Pipeline IIIMapaipi achitsulo a X80 ndi omwe amagwiritsa ntchito zoposa 80% ya ntchito zonse, zomwe zimathandiza kuti mpweya wachilengedwe uyende bwino kuchokera kumadzulo kwa China kupita ku dera la Yangtze River Delta.
Kupangidwa kwa mafuta ndi gasi m'madzi akuyaMu pulojekiti ya Liwan 3-1 gas field ku South China Sea, mapaipi achitsulo osapindika a X80 amagwiritsidwa ntchito pa mapaipi a pansi pamadzi omwe ali pansi pa madzi opitilira mamita 1,500, ndi mphamvu yokakamiza yakunja ya 35 MPa.

Chitsulo cha X90 chikuyimira m'badwo wachitatu wa zitsulo zapaipi zolimba kwambiri, mogwirizana ndi muyezo wa API 5L 47th edition. Chili ndi mphamvu yotsika ya 621 MPa, mphamvu yokoka ya 758-931 MPa, ndi carbon equivalent (Ceq) ya 0.47% kapena kuchepera. Ubwino wake waukulu ndi monga mphamvu zambiri zosungira, kusinthasintha kwa throughput weld, komanso kusinthasintha kwa kutentha kochepa.

Milandu yodziwika bwino yogwiritsira ntchito ndi iyi:

Mphamvu ya Siberia 2 Pipeline: Monga chinthu chachikulu pa ntchitoyi, chitoliro chachitsulo cha X90 chidzanyamula gasi kuchokera ku minda ya gasi ya ku West Siberia ku Russia kupita ku North China. Chitolirochi chikayamba kugwira ntchito mu 2030, chikuyembekezeka kuti kuchuluka kwa gasi pachaka kudzapereka gasi woposa 20% wa mafuta onse ochokera ku China omwe amalowa m'mapaipi.

Mzere wa Paipi ya Gasi Wachilengedwe wa ku Central Asia D: M'madera okhala ndi dothi lamchere kwambiri m'chigawo cha Uzbek, chitoliro chachitsulo cha X90, chophatikizidwa ndi njira yotetezera ya 3PE + cathodic, chimakhala ndi nthawi yogwira ntchito mpaka zaka 50.

Chophimba cha 3PE chimakhala ndi chopangira utoto wa epoxy powder (FBE), chopangira cholumikizira chapakati, ndi chophimba cha polyethylene (PE), chokhala ndi makulidwe onse a ≥2.8mm, chomwe chimapanga njira yotetezera yophatikizana "yolimba + yosinthasintha":

Gawo la maziko a FBE, lokhala ndi makulidwe a 60-100μm, limalumikizana ndi chitoliro chachitsulo, zomwe zimapangitsa kuti pakhale kukana kwabwino kwambiri (≥5MPa) komanso kukana kwa cathodic disbondment (kutuluka kwa utali wa ≤8mm pa 65°C/48h).

Chomatira Chapakatikati: 200-400μm wandiweyani, chopangidwa ndi utomoni wa EVA wosinthidwa, chimalumikizana ndi FBE ndi PE, chokhala ndi mphamvu yokopa ya ≥50N/cm kuti chisapatule pakati pa zigawo.
PE Yakunja: ≥2.5mm wandiweyani, wopangidwa ndi polyethylene yolimba kwambiri (HDPE), yokhala ndi malo ofewetsa a Vicat ≥110°C komanso kukana kukalamba kwa UV komwe kwatsimikiziridwa ndi mayeso a nyali ya xenon arc ya maola 336 (kusunga mphamvu yolimba ≥80%). Yoyenera kugwiritsidwa ntchito m'malo obiriwira a ku Mongolia komanso m'malo ozizira kwambiri.

Royal Steel Group, yomwe cholinga chake ndi "Kupanga Zinthu Mwatsopano Kuyendetsa Mphamvu Yamphamvu," ikupitilizabe kupereka zinthu zodalirika komanso zogwira ntchito bwino kwambiri komanso ntchito zaukadaulo pomanga zomangamanga zamphamvu padziko lonse lapansi.
