Na Septemba, China na Russia bịanyere aka na nkwekọrịta maka ike nke Siberia-2 eke gas pipeline. Pipeline, nke a ga-arụ site na Mongolia, bu n'obi ibubata gas sitere na mpaghara gas dị n'ebe ọdịda anyanwụ Russia na China. Site n'ike nnyefe kwa afọ nke ijeri cubic 50, a na-atụ anya na ọ ga-arụ ọrụ na gburugburu 2030.
Ike nke Siberia-2 abụghị naanị ọkpọkọ ike; ọ bụ ihe nleba anya maka imegharị usoro zuru ụwa ọnụ. Ọ na-emebi ọchịchị ike Western, na-eme ka mmekọrịta dị n'etiti China na Russia dịkwuo mma, ma na-akpali ike akụ na ụba mpaghara. Ọ na-enyekwa ihe atụ bara uru nke imekọ ihe ọnụ na-emeri emeri n'ime ụwa multipolar. N'agbanyeghị ọtụtụ ihe ịma aka teknụzụ, geopolitical na gburugburu ebe obibi chere ihu, uru atụmatụ nke ọrụ a gafere oke azụmahịa, na-aghọ ọrụ ama ama n'ịkwalite iwulite obodo nwere ọdịnihu ga-ekerịta maka ihe a kpọrọ mmadụ. Dị ka Putin kwuru na emume mbinye aka, "Pipeline a ga-ejikọta ọdịnihu anyị ọnụ."
Dị ka ụlọ ọrụ azụmaahịa mba ofesi ọkachamara na pipeline mmanụ na nchara ọpụrụiche, Royal Steel Group na-etinye aka na "Power of Siberia 2" gas pipeline project, ebe ọ na-akwado nkwado ike na amụma mmepe mpaghara n'etiti China, Russia, na Mongolia.
X80 ígwè bụ ihe nrịbama maka nchara siri ike dị elu, na-agbaso ụkpụrụ mbipụta API 5L 47th. Ọ na-enye opekempe ike mkpụrụ nke 552 MPa, ike ntakiri nke 621-827 MPa, yana oke ike nke 0.85 ma ọ bụ obere. Uru ya bụ isi dabere na imewe dị fechaa, ịdị oke ike siri ike, yana weldability kachasị mma.
Ngwa a na-ahụkarị gụnyere:
China-Russia East Line Natural Gas Pipeline: N'iji X80 ígwè eme ihe n'oge nile, ọ na-ebufe gas 38 ijeri cubic mita kwa afọ ma na-agafe permafrost na mpaghara seismically, na-esetịpụ akara ngosi zuru ụwa ọnụ maka nkà na ụzụ na-ewu pipeline.
Ihe oru ngo nke West-East Gas Pipeline III: X80 ọkpọkọ ígwè na-akpata ihe karịrị 80% nke ngụkọta ojiji, na-akwado nke ọma njem nke eke gas si n'ebe ọdịda anyanwụ China na Yangtze River Delta mpaghara.
Mmiri miri emi mmanụ na gas mmepe: Na Liwan 3-1 gas ubi oru ngo na South China Sea, X80 enweghị nkebi ígwè ọkpọkọ na-eji maka submarine pipeline na mmiri omimi karịrị 1,500 mita, na mpụga compressive ike nke 35 MPa.
Nchara X90 na-anọchi anya ọgbọ nke atọ nke ọkpọkọ ọkpọkọ dị elu, na-agbaso ụkpụrụ mbipụta API 5L 47th. O nwere opekempe ike mkpụrụ nke 621 MPa, ike tensile nke 758-931 MPa, yana carbon dakọtara (Ceq) nke 0.47% ma ọ bụ obere. Uru ya ndị bụ isi gụnyere nchekwa nchekwa dị elu, nrụpụta weldability, na ngbanwe na ọ dị ala.
Okwu ngwa ngwa gụnyere:
Ike Siberia 2 Pipeline: Dị ka isi ihe nke oru ngo, X90 ígwè pipe ga-ebu ogologo gas ụgbọ njem si Russia West Siberian gas ubi na North China. Mgbe etinyere ya na 2030, a na-atụ anya na nnyefe gas kwa afọ ga-abụ ihe karịrị 20% nke mbubata gas pipeline nke China.
Central Asia Natural Gas Pipeline Line D: N'akụkụ ala saline nke ukwuu nke ngalaba Uzbek, X90 ígwè ọkpọkọ, jikọtara ya na usoro nchebe 3PE + cathodic, nwere ndụ ọrụ ya ruo afọ 50.
Ihe mkpuchi 3PE nwere ihe mkpuchi epoxy ntụ ntụ (FBE) primer, akwa mkpuchi etiti, yana polyethylene (PE) topcoat, nke nwere oke nha nke ≥2.8mm, na-eme usoro nchekwa ihe mejupụtara "isi ike + mgbanwe":
The FBE base oyi akwa, na a ọkpụrụkpụ nke 60-100μm, kemịkalụ agbụ na ígwè ọkpọkọ elu, na-enye magburu onwe adhesion (≥5MPa) na cathodic disbondment eguzogide (peel radius ≤8mm na 65 ° C / 48h).
Ngwakọta dị n'etiti: 200-400μm gbara ọkpụrụkpụ, nke emere site na resin EVA gbanwere, jikọtara ya na FBE na PE, yana ike bee nke ≥50N / cm iji gbochie nkewa interlayer.
PE dị n'èzí: ≥2.5mm gbara ọkpụrụkpụ, nke polyethylene dị elu (HDPE), nke nwere ebe dị nro nke Vicat ≥110 ° C na mgbochi ịka nká nke UV gosipụtara site na nnwale 336-hour xenon arc (njigide ike ≥80%). Kwesịrị ekwesị maka ojiji na ala ahịhịa Mongolian na gburugburu permafrost.
Royal Steel Group, ya na ebumnuche ya nke "Material Innovation Driving the Energy Revolution," na-aga n'ihu na-enye arụmọrụ dị elu, ngwaahịa ọkpọkọ ígwè a pụrụ ịdabere na ya nke ukwuu na ọrụ nka maka owuwu akụrụngwa ike zuru ụwa ọnụ.
