S: Maxaad X60 uga doorataa X52 dhuumaha gaaska?
A: X60 waxay bixisaa xoog wax soo saar oo 15% ka sarreeya (415 MPa iyo 360 MPa), taasoo u oggolaanaysa derbiyada khafiifka ah (badanaa 10-15% dhimis) si loogu sameeyo isla heerka cadaadiska. Tani waxay yareysaa miisaanka iyo kharashka walxaha, gaar ahaan dhuumaha masaafada dheer. Si kastaba ha ahaatee, X60 waxay u baahan tahay habab alxan oo adag waxayna aad ugu nugul tahay dildilaaca haydarojiin. Cadaadiska ka hooseeya 10 MPa, X52 badanaa waa mid dhaqaale badan. Cadaadiska ka sarreeya 12 MPa, X60 ama X65 ayaa lagu talinayaa.
S: Waa maxay faraqa u dhexeeya X60 PSL1 iyo PSL2?
A: PSL2 waxay leedahay xadad kiimiko oo adag (gaar ahaan C, P, S oo hooseeya), tijaabinta saameynta Charpy ee qasabka ah (27J @ 0°C ama ka hooseeya), adkaanta ugu badan 90 HRB, waxayna u baahan tahay 100% UT oo ah tolmada alxanka (PSL1 waxay u baahan tahay oo keliya UT dhibic). Khadadka gaaska ee ka shaqeeya meelaha dadku ku badan yihiin ama heerkulka hooseeya, PSL2 badanaa waa la cayimaa.
S: Ma ku siin kartaa X60 shahaado adeeg dhanaan ah?
J: Haa. Waxaan bixinaa X60 PSL2 oo leh baaritaanka HIC (NACE TM0284) iyo baaritaanka SSC (NACE TM0177). Aqbalaadda caadiga ah: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5% HIC. PWHT waxaa loo adeegsadaa dhammaan adeegyada dhanaan X60 iyadoon loo eegin dhumucda derbiga si loo hubiyo adkaanta ≤ 85 HRB. Waxaan bixinay adeeg dhanaan X60 mashaariicda Bariga Dhexe iyo Koonfur-bari Aasiya.
S: Tijaabinta saameynta heerkulka hooseeya ee noocee ah ayaad u samayn kartaa dhuumaha arctic ee X60?
A: Waxaan tijaabin karnaa ilaa -60°C. Dhuumaha gaaska ee caadiga ah ee arctic waxay u baahan yihiin saameynta Charpy ee ugu yaraan 27J marka ay tahay -46°C. Womic badanaa waxay gaartaa 80-120J marka ay tahay -46°C. Xakamaynta faafinta jabka, waxaan sidoo kale ku sameynaa DWTT -20°C iyadoo leh ugu yaraan 85% aagga jarista. Fadlan sheeg heerkulka baaritaankaaga iyo tamarta loo baahan yahay.
S: Hawshadee ayaa ugu fiican dhuumaha X60 ee badda - JCOE ama UOE?
A: UOE waxaa loo doorbidaa badda sababtoo ah waxay soo saartaa wareegsanaan wanaagsan (±0.2% vs ±0.5% JCOE) iyo cadaadis hoose oo haraadi ah. Tani waxay muhiim u tahay u adkeysiga cadaadiska hydrostatic-ka dibadda (burburka) iyo alxanka lagu kalsoonaan karo ee ku yaal weelasha la dhigo. UOE waxay sidoo kale bixisaa waxqabad daal oo wanaagsan oo loogu talagalay kor u kaca firfircoon. Biyaha gacmeed (<100m) ee xeebta u dhow, JCOE waa la aqbali karaa.
S: Waa maxay waqtiga caadiga ah ee hogaanka ee biibiilaha X60 LSAW?
A: Waqtiga caadiga ah ee hogaanka X60 PSL1: 35-50 maalmood. X60 PSL2 oo leh tijaabinta adeegga dhanaan iyo PWHT: 50-70 maalmood. Dalabyada degdega ah (25-35 maalmood) waxay suurtogal u yihiin tiro yar (<1,000 tan) haddii saxanku kayd ku jiro. Dalabyada aadka u waaweyn (> 20,000 tan), waqtiga hogaanka wuxuu socon karaa ilaa 90 maalmood.
S: Ma bixisaa kormeer dhinac saddexaad ah oo loogu talagalay tuubooyinka X60 LSAW?
J: Haa. Waxaan la shaqeynaa SGS, BV, TÜV, DNV, ABS, iyo LR. Baaritaanka waxaa lagu sameyn karaa warshadeenna inta lagu jiro wax soo saarka, iyadoo uu goobjoog ka yahay wakiilka macmiilka. Waxaan soo saarnaa shahaadooyinka EN 10204 Nooca 3.2 marka la codsado.
Tixraaca Mashruuca - Khadka Gaaska Dabiiciga ah ee Koonfur-bari Aasiya
Dalka:Gobolka xadka Myanmar iyo Thailand (dhuumaha gaaska ee ka yimaada Gacanka Martaban ilaa Thailand)
Heerka & Darajada:API 5L X60 PSL2 (adeeg dhanaan, oo leh HIC iyo SSC test)
Cabbirka iyo Tirada:
●OD 813mm (32″) × Miisaan 19.0mm – 36,000 mitir (qiyaastii 12,600 tan) oo ay soo saartay habka UOE
●OD 813mm (32″) × Miisaan 22.0mm – 8,000 mitir (qiyaastii 3,200 tan) oo ay soo saartay habka UOE (derbi qaro weyn oo loogu talagalay isgoysyada waddooyinka/tareenka)

Wadarta:56,000 mitir (56 km), qiyaastii 18,200 tan
Tilmaamaha:Dahaarka 3LPE ee dibadda (dhumucda guud ee 3.0mm) sida ISO 21809, dhammaadka godan 30° / 1.6mm wejiga xididka oo leh ilaaliyaha gudaha ee bevel, baaritaanka hydrotest at 15.0 MPa (cadaadiska naqshadeynta 11.5 MPa). Saamaynta Charpy ee qasabka ah ee 0°C iyo -20°C (ugu yaraan 27J, la gaaray 90-140J). HIC halkii NACE TM0284 Xalka A, 96h - aqbalaad: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. SSC halkii NACE TM0177 Habka A, 720h - looma oggola dildilaac. PWHT ayaa loo adeegsaday dhammaan tuubooyinka leh WT ≥ 19.0mm. 100% UT otomaatig ah oo leh TOFD si loogu tolo alxanka. Tijaabada shucaaca (RT) ee muunadaha u-qalmitaanka alxanka goobta.
Codsiga:Khadka gaaska dabiiciga ah ee xuduudaha ka gudba ayaa gaaska ka soo qaada beeraha badda ee Gacanka Martakan (Myanmar) una gudbiya terminaal ku yaal xeebta Thailand, ka dibna u sii gudbiya warshad koronto oo gaas ku shaqeysa. Qaybta xeebta ee 56 km ah waxay ka gudubtaa dhul buuraley ah oo leh isbeddello kor u kac ah oo muhiim ah (ilaa 400m), oo lagu daray lix isgoys oo waaweyn oo waddooyin ah iyo saddex isgoys oo tareen ah.
Caqabadaha Farsamada iyo Xalalka:
●U hoggaansanaanta adeegga dhanaan ee gaaska oo leh raad H₂S– Gaaska dabiiciga ah wuxuu ka kooban yahay 5-10 ppm H₂S heerkulka hawlgalka 55°C. Womic waxay samaysay tijaabinta HIC iyo SSC 12 goobood oo wax soo saar ah. Dhammaantood waxay ku gudbeen CLR 0%, CTR 0%, CSR 0% HIC. Tijaabada SSC (NACE TM0177, 720h) ma muujin wax dildilaac dusha sare ah. Waxaan tan ku gaarnay annagoo ilaalinayna CEV ≤ 0.38%, annagoo PWHT ku marinayna dhammaan tuubooyinka 19.0mm iyo 22.0mm WT (inkastoo API 5L aysan u baahnayn PWHT ka hooseeya 25.4mm), iyo xakamaynta gelinta kulaylka alxanka ilaa ≤ 2.8 kJ/mm. Kormeeraha macmiilka (BV) wuxuu markhaati ka ahaa dhammaan tijaabooyinka wuxuuna xaqiijiyay natiijooyinka.
●Dhul buuraley ah oo leh foorarsi dherer sare leh– Wadada dhuumaha waxaa ku jira jiirada ilaa 25 darajo. Laabista goobta ee tuubooyinka X60 way ka adag tahay heerarka hoose sababtoo ah xoog sare. Womic waxay bixisay tuubooyin leh isku-xidhyo hal-dheer ah oo dheer (18m halkii laga isticmaali lahaa 12m caadiga ah) si loo yareeyo tirada leexashada goobta 33%. Waxaan sidoo kale bixinnay qaab-dhismeed gaar ah oo bevel ah (bevel isku-dhafan) kaas oo u oggolaanaya ±3° khaladaad inta lagu jiro alxanka goobta iyada oo aan wax u dhimayn tayada alxanka. Uvality-ga waxaa lagu hayay ≤ 0.3% (habka UOE) si loo hubiyo isku-xidhka saxda ah ee jiirada.
●Daacadnimada dahaarka 3LPE ee deegaanka kaynta– Qoyaan badan (80-95% sanadka oo dhan) iyo carrada laterite ee xoqan ayaa khatar ku ah dahaarka. Dumarku waxay mareen dahaar 3LPE ah oo leh lakab kale oo 0.3mm ah. Waxaan sameynay 100% ogaanshaha fasaxa 7kV (heerka 5kV) waxaana cabirnay xoogga diirka 25°C iyo 70°C (230 N/cm heerkulka 25°C, 160 N/cm heerkulka 70°C). Dahaarka ayaa ka gudbay tijaabada kala-goynta cathodic (≤ 8mm radius heerkulka 65°C, 28 maalmood).
●Saadka xuduudaha ka gudba oo leh dhibka kastamka– Tuubooyinka waxaa laga soo raray Shanghai ilaa dekedda Yangon (Myanmar), ka dibna waxaa la geeyay 280 km si loo gaarsiiyo dhuumaha ku fidsan xuduudda Thailand. Wadadu waxay martaa laba kontarool oo kastam ah. Womic waxay diyaarisay dukumentiyo gaar ah oo dalka ah (Shahaadada Asalka ee foomka AK, ASEAN-wide). Waxaan sidoo kale diyaarinay curaar ku meel gaar ah oo soo dejinta ah si looga fogaado dib u dhaca bixinta canshuurta. Dhammaan 18,200 oo tan ayaa la fasaxay kastamka 5 maalmood gudahood.
●Xakamaynta kulaylka alxanka ee adag ee X60– X60's HAZ wuxuu u nugul yahay kulaylka xad-dhaafka ah, kaas oo sababi kara jilcin iyo yareynta adkaanta. Womic waxay isticmaashay nidaam SAW oo laba-xarig ah oo leh la socodka kulaylka marin kasta oo alxanka ah. Celceliska kulaylka gelinta alxanka gudaha: 2.2 kJ/mm, alxanka dibadda: 2.5 kJ/mm (ka hooseeya xadka 3.5 kJ/mm). Heerkulka interpass-ka waxaa lagu hayay ka hooseeya 200°C. Adkaynta alxanka isdhaafka ah ka dib PWHT: birta salka ah 78-82 HRB, alxanka 82-86 HRB, HAZ 80-84 HRB - dhammaantood waxay ku jiraan xadka 90 HRB.
● Natiijo:Dhuumaha gaaska waxaa la howlgeliyay Q3 2024. Dhammaan 56 km ee tuubooyinka X60 PSL2 waxay ka gudbeen kormeer dhinac saddexaad ah oo ay samaysay BV Myanmar. Macmiilku wuxuu soo sheegay inaysan jirin cillado alxan ah intii lagu jiray alxanka wareegga goobta (in ka badan 4,600 alxanka wareegga). Dhuumaha ayaa shaqeynayay 10.5-11.0 MPa muddo 12 bilood ah iyada oo aan wax daadasho ah ama cillado dahaadh ah lahayn. Womic Steel waxay heshay abaalmarinta "Alaab-qeybiyaha Sanadka" qandaraaslaha EPC ee Thailand si loogu keeno waqtigii loogu talagalay (dhammaan 18,200 oo tan oo la keenay 68 maalmood gudahood) iyo waxqabad tayo leh.
