● OD 1,219mm (48″) × Ubwinshi 22.2mm – metero 15.000 (hafi toni 9.500) yakozwe na UOE process (urukuta runini rwo kwambuka imisozi n'uturere tw'ibiza)

● OD 1,016mm (40″) × Uburemere 17.5mm – 40.000 metero (hafi toni 17.800) yakozwe na JCOE process (umurongo w'ishami)
Igiteranyo:Metero 140.000 (140 km), hafi toni 75.800

Ibisobanuro:Irangi ryo hanze rya 3LPE (3.0mm yose hamwe), impera zikozweho 30°/1.6mm, ikizamini cya hydrotest kuri 19.5 MPa (igipimo cy'umuvuduko wa 15.0 MPa). Ingufu za Charpy zisabwa kuri -20°C (ubugari bwa 80J, zageze kuri 150-220J) no kuri -46°C (ubugari bwa 50J, zageze kuri 100-160J). DWTT kuri -20°C: ubuso bwo gukata ≥ 85% ku mubiri w'umuyoboro, ≥ 70% ku gusudira. UT yuzuye (100% by'ingano y'umuyoboro, ntabwo ari umushongi gusa). Igenzura ryakozwe n'umuntu wa gatatu na TÜV Rheinland mu gihe cyose cyo gukora. DNV yabonye isuzuma rya hydrostatic kuri 10% by'umusaruro.

Porogaramu:Kwagura umuyoboro wa gaze uhuza Aziya yo Hagati n'Ubushinwa (Umurongo wa D), utwara gaze karemano iva mu bibanza bya gaze muri Uzbekistan inyuze muri Tajikistan ikagera ku mupaka w'Ubushinwa. Uburebure bw'umuyoboro wose: kilometero 140. Umuyoboro unyura mu misozi miremire ya Pamir, harimo uduce tune tw'ubutaka bw'imitingito, inzira eshatu nini zo kwambuka imigezi, n'impinduka z'ubutumburuke kuva kuri metero 400 kugeza kuri metero 2,800.

Ibibazo bya tekiniki n'ibisubizo:

● Ihindagurika ry'ubutumburuke n'ubushyuhe bukabije– Ubutumburuke bw'imiyoboro buri hagati ya metero 400 na metero 2.800, ubushyuhe buri hagati ya -35°C mu gihe cy'itumba bukagera kuri +45°C mu mpeshyi. Imiyoboro ya santimetero 48 X70 yakeneraga gukomera ku bushyuhe buke kugeza kuri -46°C (Charpy min 50J). Womic yatoranyije plaque za TMCP zongewemo nikeli (Ni ≤ 0.50%) kugira ngo igere ku ngaruka za Charpy kuri -46°C impuzandengo ya 120J. DWTT kuri -20°C scatter area: 92-96% ku mubiri w'umuyoboro, 82-88% ku gusudira. Ibizamini byose byatsinzwe.

● Uburyo bwo kwambukiranya ikosa rya seismic - bushingiye ku gukurura– Ibice bine by'imiyoboro bihuza amakosa ashobora gukorwa hamwe n'aho ubutaka bushobora kwimura metero 1.5. Umuyoboro wakozwe hakoreshejwe igishushanyo mbonera gishingiye ku gukurura (atari ugushingiye ku guhangayika). Ibi bisaba imiyoboro ya X70 ifite igipimo cy'umusaruro cyagenwe ≤ 0.85 (API 5L PSL2 yemerera 0.93) n'uburebure bungana ≥ 15%. Womic yakoze X70 yihariye "ifite uburemere bwinshi" ifite igipimo cy'umusaruro 0.80-0.84 n'uburebure bungana 16-18%. Twanatanze isuzuma ry'uburyo bwo gukurura mu gice cyose (atari ugukurura gusa) kugira ngo tumenye neza ubushobozi bwo gukurura.

● Ubuso bw'imisozi bufite ibisabwa cyane byo kugorora– Umuyoboro urimo imiyoboro ya santimetero 22 ya 48 yashyizwe ku misozi ya dogere 20-30. Gupfunyika mu buryo bukonje bw'imiyoboro ya X70 ni bike (API 5L yemerera 1.5° kuri metero 12). Imiyoboro ya Womic ifite imiyoboro miremire ya metero 18 ku bice bigororotse n'imiyoboro ya metero 12 ku bice bicuramye. Twanakoze isuzuma ry'imiyoboro ku bipimo byuzuye: imiyoboro ya santimetero 48 × 19.0mm yapfunyitse mu buryo bukonje kugeza kuri 2.0° kuri metero 12 nta gucikagurika (byemejwe na UT na MT nyuma yo gupfunyika).

● Kwambuka imigezi bisaba ubugari bw'inkuta zikomeye– Imigezi itatu yambukiranywagamo (imigezi ya Oxus) yasabaga 22.2mm WT aho kuba 19.0mm kugira ngo yongere ipfunduke kandi ikomeze kunama mu gihe cyo gushyiraho imiyoboro yo gukurura. Womic yakoresheje uburyo bwa UOE kuri iyi miyoboro kugira ngo igere ku rugero rwa ≤ 0.2% (ukuri ni 0.12-0.18%), bigatuma inzira inyura mu mwobo woroshye. Imiyoboro miremire yo ku rukuta yasabaga kandi ko ubushyuhe buke bugabanuka mu gihe cyo gusudira (≤ 2.0 kJ/mm) kugira ngo ikomeze gukomera kwa HAZ.

● Ibikoresho byo mu ntera ndende mu bihugu bitatu– Imiyoboro yakozwe mu ruganda rwa Womic rwa Tianjin, yoherezwa muri Almaty (Kazakisitani) hakoreshejwe gari ya moshi, hanyuma ijyanwa mu makamyo kugira ngo ishyirwe mu bwubatsi muri Uzbekistan na Tajikistan. Intera yose yo gutwara: irenga kilometero 5.000. Womic yakoresheje imodoka za gari ya moshi zihariye zifite ibikoresho bifatanye n'ibyuma. Buri muyoboro wasuzumwe hakoreshejwe RFID ahantu hose ho kwimurirwa. Nta miyoboro yangiritse mu gihe cyo kuyimurira nubwo habayeho kwambuka imipaka itatu n'ibindi 6 byoherejwe.

● Ibisabwa cyane kugira ngo umuntu agaragare ku mirasire y'izuba iri ahantu hanini cyane– Ku butumburuke bwa metero 2,800, imirasire ya UV iri hejuru ya 40% ugereranyije n'iyo ku nyanja. 3LPE isanzwe ishobora kwangirika iyo UV iri hejuru cyane. Womic yashyizeho 3LPE hamwe n'urwego rwo hejuru rwa UV-stabilized (umukara wa karuboni 2.5% ugereranije n'urugero rwa 2.0%). Irangi ryatsinze ikizamini cyihuse cyo kuvura UV (1,000 hours QUV, gloss retention ≥ 80%). Ingufu zo gusiga zagumyeho > 200 N/cm nyuma yo guhura na UV.

● Ibisubizo:Kwagura umuyoboro wa kilometero 140 byararangiye kandi byatangiye gukoreshwa mu gihembwe cya kabiri cya 2025. Toni 75.800 zose z'imiyoboro ya X70 PSL2 zanyuze mu igenzura rya TÜV nta na kimwe zanze. Ibice by'igishushanyo mbonera byarokotse ingaruka ebyiri z'imitingito (ingano ya 4.2 na 5.1) mu mezi 18 ya mbere y'akazi nta kimenyetso cyo gucika cyangwa gusohoka kw'amazi. Umukiriya (ikigo cy'igihugu gishinzwe lisansi muri Uzbekistan) yashimiye ku mugaragaro Womic Steel ku "kugenzura ubuziranenge budasanzwe no gushyigikira tekiniki." Womic ubu ni yo ihabwa amahirwe menshi yo gutanga ibice bya Line D mu gihe kizaza.
