Su'aalaha Badiya La Weydiiyo:

S: Maxaad X70 uga doorataa X65 dhuumaha gaaska ee masaafada dheer?
A: X70 waxay bixisaa xoog wax soo saar oo 8% sare ah (485 vs 450 MPa), taasoo u oggolaanaysa in dhumucda derbiga la dhimo qiyaastii 10-12% cadaadis isku mid ah. Dhuumaha 1,000 km ah, tani waxay badbaadin kartaa 50,000-80,000 oo tan oo bir ah, taasoo si weyn u yareynaysa kharashka agabka iyo raadadka kaarboonka. Si kastaba ha ahaatee, X70 waxay u baahan tahay taarikada TMCP oo qaali ah, xakamaynta alxanka oo adag, iyo kharashyada kormeerka oo sarreeya. Barta jebinta badanaa waa qiyaastii 500-800 km. Dhuumaha gaagaaban, X65 waa mid dhaqaale ahaan ka dhaqaale badan.

S: X70 ma ka adag tahay in lagu alxamo goobta marka loo eego X65?
J: Haa. X70 wuxuu leeyahay u dhigma kaarboon oo sarreeya (CEV 0.38-0.43% vs X65 0.35-0.40%) wuxuuna aad ugu nugul yahay dildilaaca haydarojiin. Alxanka goobta wuxuu u baahan yahay kuleylin hore (caadiyan 100-150°C X70 vs 75-100°C X65) iyo xakameyn adag oo ku saabsan gelinta kulaylka iyo heerkulka dhex-dhexaadka. Si kastaba ha ahaatee, iyadoo la adeegsanayo hababka alxanka ee aqoonta leh (WPS) iyo alxanleyaal xirfad leh, X70 si kalsooni leh ayaa loo alxan karaa. Womic waxay bixisaa talooyin la isticmaali karo oo alxanka ah waxayna bixin kartaa kuubanno shahaado haysta.

S: Ma loo isticmaali karaa X70 adeeg dhanaan (H₂S)?
J: Haa, laakiin waxay u baahan tahay tallaabooyin dheeraad ah: CEV ≤ 0.38% (la doorbidayo ≤ 0.36%), PWHT dhammaan dhumucda derbiga, adkaanta ≤ 85 HRB, HIC iyo baaritaanka SSC. Womic waxay bixisay adeeg dhanaan X70 mashruucyada leh ilaa 50 ppm H₂S. Ogow in X70 uu aad ugu nugul yahay H₂S marka loo eego X65 ama X60, sidaas darteed hawl-wadeenno badan ayaa weli doorbida X65 jawiyada H₂S ee sare.

S: Waa maxay dhumucda derbiga ugu badan ee tuubada X70 LSAW?
J: JCOE/UOE ugu badnaan 50.8mm, saxanka la duubay hal tolmo ilaa 70mm. Dhumucda derbiga oo ka badan 40mm, qalabka UOE wuu xaddidan yahay, saxanka la duubayna waa la doorbidaa. Dhawaan waxaan bixinnay X70 914mm OD × 60mm WT oo loogu talagalay dhuumaha CO₂ ee cadaadiska sare leh (mashruuca CCS).

S: Waa maxay tijaabada adkaanta jabka ee looga baahan yahay X70?
A: API 5L waxay u baahan tahay baaritaanka Charpy V-Notch (27J daqiiqo) laakiin mashaariicda badankood waxay qeexaan qiimayaal sare (tusaale ahaan, 100J at -20°C). DWTT waxaa looga baahan yahay xakamaynta faafinta jabka (aagga gooynta ≥ 85% heerkulka tijaabada). Tuubooyinka badda ama arctic, baaritaanka CTOD (≥ 0.25mm at -20°C ama -46°C) ayaa badanaa lagu daraa. Womic waxay dhammaan tijaabooyinkan ku fulisaa gudaha ama iyada oo loo marayo shaybaarro dhinac saddexaad ah oo la aqoonsan yahay.

S: Waa maxay waqtiga caadiga ah ee hogaanka ee biibiilaha X70 LSAW?
J: X70 waxay u baahan tahay taarikada TMCP kuwaas oo leh waqtiyo rasaas oo dheer (8-12 toddobaad laga bilaabo warshadda). Wadarta wakhtiga rasaasta: 70-100 maalmood laga bilaabo dalabka ilaa rarista FOB. Dalabyada degdegga ah (45-60 maalmood) waa suurtogal haddii taarikada la keydiyo.

S: X70 ma u baahan yahay PWHT adeeg aan dhanaan lahayn?
A: API 5L kuma qasbayo PWHT X70 oo ka hooseeya 50.8mm WT. Si kastaba ha ahaatee, hawl-wadeenno badan ayaa PWHT u adeegsada dhuumaha X70 iyadoon loo eegin dhumucda derbiga si loo yareeyo cadaadiska harsan loona hubiyo adkaanta HAZ. Womic waxay bixin kartaa PWHT marka la codsado (kharash dheeraad ah iyo waqtiga hogaanka).

Wadarta:140,000 mitir (140 km), qiyaastii 75,800 tan

Tilmaamaha:Dahaarka 3LPE ee dibadda (wadarta 3.0mm), dhammaadka la jaray 30°/1.6mm, baaritaanka hydrotest 19.5 MPa (cadaadiska naqshadeynta 15.0 MPa). Saamaynta Charpy ee qasabka ah -20°C (ugu yaraan 80J, la gaaray 150-220J) iyo -46°C (ugu yaraan 50J, la gaaray 100-160J). DWTT at -20°C: aagga gooynta ≥ 85% jirka tuubada, ≥ 70% alxanka. UT-ga jirka oo dhan (100% mugga tuubada, ma aha oo kaliya tolmo). Kormeer dhinac saddexaad ah oo ay samaysay TÜV Rheinland inta lagu jiro wax soo saarka. DNV waxay aragtay tijaabinta hydrostatic ee 10% wax soo saarka.

Codsiga:Kordhinta Dhuumaha Gaaska ee Aasiyada Dhexe iyo Shiinaha (Line D), oo gaaska dabiiciga ah ka soo qaada beeraha gaaska ee Uzbekistan iyada oo loo marayo Tajikistan ilaa xadka Shiinaha. Wadarta dhererka xariiqda fidintan: 140 km. Dhuumaha ayaa dhex mara buuraha Pamir, oo ay ku jiraan afar aag oo dhulgariir firfircoon, saddex isgoys oo webi ah oo waaweyn, iyo isbeddel dherer ah oo ka yimid 400m ilaa 2,800m.

Caqabadaha Farsamada iyo Xalalka:

● Kala duwanaansho heer sare iyo heerkul oo aad u sarreeya– Kor u kaca dhuumaha wuxuu u dhexeeyaa 400m ilaa 2,800m, iyadoo heerkulka deegaanku uu ka bilaabmayo -35°C xilliga jiilaalka ilaa +45°C xagaaga. Tuubooyinka 48" X70 waxay u baahnaayeen adkeysi heerkul hooseeya ilaa -46°C (Charpy min 50J). Taarikada TMCP ee Womic waxay dooratay oo lagu daray nikkel (Ni ≤ 0.50%) si loo gaaro saameynta Charpy ee -46°C celcelis ahaan 120J. DWTT aagga jarista -20°C: 92-96% jirka tuubada, 82-88% alxanka. Dhammaan tijaabooyinka ayaa la maray.

● Isgoyska cilladaha dhulgariirka - naqshad ku salaysan cadaadis– Afar qaybood oo dhuumaha ah ayaa ka gudba cillado firfircoon oo leh barokac dhuleed oo suurtagal ah ilaa 1.5m. Dhuumaha waxaa loogu talagalay iyadoo la adeegsanayo naqshad ku salaysan cadaadis (aan ku salaysnayn cadaadiska). Tani waxay u baahan tahay tuubooyinka X70 oo leh saamiga wax soo saarka ee la cayimay ≤ 0.85 (API 5L PSL2 waxay u oggolaanaysaa 0.93) iyo fidin isku mid ah ≥ 15%. Womic waxay soo saartay X70 gaar ah oo "caadi sare leh" oo leh saamiga wax soo saarka 0.80-0.84 iyo fidin isku mid ah 16-18%. Waxaan sidoo kale bixinnay tijaabinta jiidista qaybta oo dhan (ma aha oo kaliya xariijin) si loo xaqiijiyo awoodda cadaadiska.

● Dhul buuraley ah oo leh shuruudo aad u qalloocan– Dhuumaha waxaa ku jira 22 km oo tuubo 48" ah oo lagu rakibay jiirada 20-30 digrii. Qaloocinta qabow ee tuubooyinka X70 waa xaddidan tahay (API 5L waxay u oggolaanaysaa 1.5° 12mkiiba). Tuubooyinka Womic waxay bixiyeen oo leh isku-xidhyo 18m oo dheer ah oo loogu talagalay qaybaha toosan iyo isku-xidhyo 12m ah oo loogu talagalay qaybaha qalloocan. Waxaan sidoo kale samaynay tijaabinta qalloocan ee muunado buuxa: tuubooyinka 48" × 19.0mm waxaa loo rogay qabow ilaa 2.0° 12mkiiba iyada oo aan la dillaacin (waxaa xaqiijiyay UT iyo MT ka dib markii la foorarsado).

● Isgoysyada wabiga oo u baahan dhumuc derbi oo culus– Saddex meelood oo wabiga laga gudbo (Oxus submarines) waxay u baahnaayeen 22.2mm WT halkii ay ka ahaan lahaayeen 19.0mm si loo helo iska caabin dheeraad ah oo burbur iyo foorarsi ah inta lagu jiro rakibidda dib-u-soo-celinta. Womic waxay isticmaashay habka UOE ee tuubooyinkan si ay u gaarto qaab-dhismeedka ≤ 0.2% (dhab ahaantii 0.12-0.18%), taasoo hubinaysa marin siman oo loo maro godka. Tuubooyinka derbiga ee qaro weyn ayaa sidoo kale u baahnaa in la geliyo kulayl yar inta lagu jiro alxanka (≤ 2.0 kJ/mm) si loo ilaaliyo adkaanta HAZ.

● Saadka masaafada dheer ee saddex waddan– Tuubooyinka waxaa lagu sameeyay warshadda Tianjin ee Womic, waxaana lagu raray tareen ilaa Almaty (Kazakhstan), ka dibna waxaa loo wareejiyay gawaarida xamuulka qaada si loogu geeyo meelaha dhismaha ee Uzbekistan iyo Tajikistan. Wadarta masaafada gaadiidka: in ka badan 5,000 km. Womic waxay isticmaashay baabuur tareen oo gaar ah oo leh taageerooyin iyo bir bir ah. Tuubo kasta waxaa lagu sawiray RFID meel kasta oo la wareejinayo. Ma jiraan tuubooyin waxyeello soo gaartay intii lagu jiray gaadiidka inkastoo 3 isgoys oo xuduud ah iyo 6 isgoys oo isgoys ah.

● Shuruudaha dahaarka xad-dhaafka ah ee soo-gaadhista UV-ga ee dhererka sare– Marka uu gaaro 2,800m, shucaaca UV wuxuu ka sarreeyaa 40% heerka badda. Heerka 3LPE ee caadiga ah wuu burburi karaa marka uu gaaro heerka UV sare. Dumarku waxay mareen 3LPE oo leh lakab sare oo UV-xasilloon (madow kaarboon ah 2.5% marka loo eego heerka 2.0%). Dahaarka ayaa ka gudbay tijaabada cimilada UV ee degdega ah (1,000 saacadood QUV, haynta dhalaalka ≥ 80%). Xoogga diirka ayaa ahaa > 200 N/cm ka dib soo-gaadhista UV.

● Natiijo:Kordhinta dhuumaha 140 km ayaa la dhammeeyay oo la howlgeliyay rubuci labaad ee 2025. Dhammaan 75,800 oo tan oo tuubooyinka X70 PSL2 ah ayaa maray kormeerka TÜV iyadoo aan wax diidmo ah la siin. Qaybaha naqshadeynta ee ku salaysan cadaadiska ayaa ka badbaaday laba dhacdo oo dhulgariir ah (magnitude 4.2 iyo 5.1) intii lagu jiray 18-kii bilood ee ugu horreeyay ee hawlgalka iyada oo aan wax calaamado ah oo gariir ama daadasho ah la arkin. Macmiilka (shirkad gaas oo qaran oo ka tirsan Uzbekistan) ayaa si rasmi ah u amaantay Womic Steel "xakamaynta tayada gaarka ah iyo taageerada farsamada." Womic hadda waa alaab-qeybiyaha la doorbidayo ee qaybaha mustaqbalka ee Line D.
