Nkhani - China ndi Russia zinasaina mgwirizano wa Mphamvu ya Siberia-2 mapaipi a gasi. Gulu la Royal Steel Group lidawonetsa kufunitsitsa kwake kuthandizira chitukuko cha dziko. |

Mu Seputembala, China ndi Russia zidasaina mgwirizano wapaipi yamafuta achilengedwe ku Siberia-2. Paipiyi, yomwe idzamangidwe kudutsa ku Mongolia, ikufuna kupereka mpweya wachilengedwe kuchokera kumadera akumadzulo kwa Russia kupita ku China. Ndi mphamvu yotumiza pachaka ya ma cubic metres 50 biliyoni, ikuyembekezeka kugwira ntchito chakumapeto kwa 2030.

Mphamvu ya Siberia-2 ndi yoposa payipi yamagetsi; ndi njira yabwino yosinthira dongosolo ladziko lonse lapansi. Imalepheretsa mphamvu yaku Western mphamvu, imakulitsa mgwirizano pakati pa China ndi Russia, ndikulimbitsa mphamvu zachuma zachigawo. Zimaperekanso chitsanzo chothandiza cha mgwirizano wopambana-wopambana m'dziko lamitundu yambiri. Ngakhale akukumana ndi zovuta zambiri zaukadaulo, zandale, komanso zachilengedwe, luso la pulojekitiyi limadutsa malire amalonda, kukhala projekiti yofunikira polimbikitsa kumanga mudzi womwe uli ndi tsogolo logawana la anthu. Monga momwe Putin adanena pamwambo wosayina, "Njira iyi idzagwirizanitsa tsogolo lathu pamodzi."

Monga kampani yamalonda yakunja yomwe imagwira ntchito pa mapaipi amafuta ndi zitsulo zapadera, Gulu la Royal Steel likukhudzidwa kwambiri ndi ntchito yamapaipi amafuta achilengedwe a "Power of Siberia 2", komanso imathandizira mgwirizano wamagetsi ndi mfundo zachitukuko zachigawo pakati pa China, Russia, ndi Mongolia.

Mapaipi atatu akuda otsekeredwa akulu akulu akulu a kaboni

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

Chitsulo cha X80 ndi chizindikiro cha chitsulo chapaipi champhamvu kwambiri, chogwirizana ndi API 5L 47th edition standard. Amapereka mphamvu zochepa zokolola za 552 MPa, mphamvu yamphamvu ya 621-827 MPa, ndi chiwerengero cha zokolola za 0,85 kapena zochepa. Ubwino wake waukulu wagona pamapangidwe opepuka, kulimba mtima kwambiri, komanso kuwongolera bwino.

Zomwe zimagwiritsidwa ntchito ndizo:
China-Russia East Line Natural Gasi Pipeline: Pogwiritsa ntchito chitsulo cha X80 ponseponse, imatumiza gasi wokwana ma kiyubiki mita 38 biliyoni chaka chilichonse ndikudutsa madera omwe ali ndi chisanu komanso madera osasunthika, ndikuyika chizindikiro chapadziko lonse chaukadaulo womanga mapaipi am'mphepete mwa nyanja.

Ntchito ya West-East Gas Pipeline III: Mapaipi achitsulo a X80 amapitilira 80% ya ntchito yonse, kuthandizira kuyendetsa bwino kwa gasi wachilengedwe kuchokera kumadzulo kwa China kupita kudera la Yangtze River Delta.
Kukula kwamafuta ndi gasi m'madzi akuya: Mu ntchito ya gasi ya Liwan 3-1 ku South China Sea, mapaipi achitsulo opanda msoko a X80 amagwiritsidwa ntchito popanga mapaipi apansi pamadzi pamadzi akuya opitilira 1,500 metres, ndi mphamvu yakunja ya 35 MPa.

Chitsulo cha X90 chikuyimira m'badwo wachitatu wazitsulo zamapaipi amphamvu kwambiri, zomwe zimagwirizana ndi API 5L 47th edition standard. Lili ndi mphamvu zochepa zokolola za 621 MPa, mphamvu yamphamvu ya 758-931 MPa, ndi mpweya wofanana (Ceq) wa 0.47% kapena wocheperapo. Ubwino wake waukulu ndi kusungitsa mphamvu zambiri, kukhazikika kwamphamvu, komanso kusinthasintha kwa kutentha.

Milandu yodziwika bwino yogwiritsira ntchito ndi:

Mphamvu ya Siberia 2 Pipeline: Monga maziko a polojekitiyi, chitoliro chachitsulo cha X90 chidzayendetsa gasi mtunda wautali kuchokera ku minda ya gasi ku West Siberia kupita ku North China. Mukayamba kugwira ntchito mu 2030, kuchuluka kwa gasi pachaka kukuyembekezeka kupitilira 20% yazinthu zonse zaku China zomwe zimatumizidwa kunja.

Central Asia Natural Gas Pipeline Line D: M'madera amchere amchere kwambiri a gawo la Uzbek, chitoliro chachitsulo cha X90, chophatikizidwa ndi 3PE + cathodic chitetezo dongosolo, ali ndi moyo wautumiki mpaka zaka 50.

Chophimba cha 3PE chimakhala ndi choyambira cha epoxy powder (FBE), chomata chapakati, ndi polyethylene (PE) topcoat, yokhala ndi makulidwe a ≥2.8mm, kupanga "yolimba + yosinthika" yodzitetezera:

FBE m'munsi wosanjikiza, ndi makulidwe a 60-100μm, mankhwala zomangira zitsulo chitoliro pamwamba, kupereka adhesion kwambiri (≥5MPa) ndi cathodic disbondment kukana (peel utali ≤8mm pa 65 ° C/48h).

Zomatira Zapakatikati: 200-400μm wandiweyani, wopangidwa ndi utomoni wosinthidwa wa EVA, wolumikizana ndi FBE ndi PE, ndi mphamvu ya peel ya ≥50N/cm kuteteza kupatukana kwapakati.
PE yakunja: ≥2.5mm wandiweyani, wopangidwa ndi polyethylene yapamwamba kwambiri (HDPE), yokhala ndi Vicat softening point ≥110 ° C ndi UV kukana kukalamba kumatsimikiziridwa ndi 336-hour xenon arc test test (tensile mphamvu yosungira ≥80%). Zoyenera kugwiritsidwa ntchito m'malo a udzu waku Mongolia komanso malo okhala ndi permafrost.

Royal Steel Group, ndi ntchito yake ya "Material Innovation Driving the Energy Revolution," ikupitiliza kupereka zida zapamwamba, zodalirika zamapaipi achitsulo ndi ntchito zaukadaulo pomanga maziko amagetsi padziko lonse lapansi.
