Su'aalaha Badiya La Weydiiyo:
S: Waa maxay faraqa u dhexeeya X65 iyo X60 ee dhuumaha badda?
A: X65 waxay bixisaa xoog wax soo saar oo 8% ka sarreeya (450 vs 415 MPa), taasoo u oggolaanaysa derbiyo khafiif ah. Biyaha qotoda dheer (≥ 1,000m), X65 waxaa badanaa la door bidaa iska caabbinta burburka iyo waxqabadka daalka. Si kastaba ha ahaatee, X65 waxay u baahan tahay habab alxan oo adag waxayna aad ugu nugul tahay dildilaaca haydarojiin. Qoto dheer ee biyaha < 500m, X60 waxay noqon kartaa mid dhaqaale ahaan ka dhaqaale badan.
S: Ma ku siin kartaa X65 baaritaanka CTOD ee loogu talagalay dadka ka soo baxa xeebaha?
J: Haa. Waxaan sameynaa tijaabada CTOD sida ku cad BS 7448 ama ASTM E1820 heerkul cayiman (badanaa -20°C ama -46°C). Qiimaha ugu yar ee CTOD: 0.25mm birta alxanka, 0.30mm HAZ. Waxaan siinay X65-ka la tijaabiyay CTOD北海iyo mashaariicda xeebaha Koonfur-bari Aasiya.
S: Waa maxay dhumucda derbiga ugu badan ee tuubada X65 LSAW?
J: JCOE/UOE ugu badnaan 50.8mm, saxanka la duubay hal tolmo ilaa 70mm, saxanka la duubay laba tolmo ilaa 80mm. Dhumucda derbiga oo ka badan 50.8mm, PWHT waa qasab. Dhawaan waxaan bixinnay X65 1,016mm OD × 60mm WT si loogu isticmaalo dhuumaha CO₂ ee cadaadiska sare leh.
S: Sidee baad u hubin kartaa adkeysiga HAZ ee alxanka goobta X65?
A: Waxaan xakameynaa kiimikada saxanka (CEV hooseeya, ≤ 0.40%), kulaylka la geliyo inta lagu jiro SAW (≤ 2.5 kJ/mm), iyo heerkulka dhex-dhexaadka ah (≤ 200°C). Waxaan macaamiisha siinaa talooyin ku saabsan shuruudaha habka alxanka (WPQ) waxaana bixin karnaa muunado la isticmaali karo oo alxanka ah. Saamaynta caadiga ah ee HAZ Charpy ee -20°C: 120-200J.
S: X65 ma ku habboon yahay adeeg dhanaan (H₂S)?
J: Haa, laakiin waxay u baahan tahay PSL2 oo leh CEV hooseeya (≤ 0.40%), PWHT dhammaan dhumucda derbiga ≥ 20mm, adkaanta ≤ 85 HRB, iyo tijaabada HIC/SSC. Womic waxay adeeg dhanaan X65 siisay Bariga Dhexe (30 ppm H₂S) iyo Kanada (gaas dhanaan).
S: Waa maxay waqtiga caadiga ah ee hogaanka ee biibiilaha X65 LSAW?
A: Heerka X65 PSL1: 40-55 maalmood. X65 PSL2 oo leh adeeg dhanaan iyo PWHT: 60-80 maalmood. Dalab degdeg ah (30-45 maalmood) tiro ka yar 2,000 tan oo suurtagal ah haddii saxannada kaydka ku jiraan.

Codsiga:Dhuumaha dhoofinta gaaska biyaha qotoda dheer laga bilaabo goobta Balder (qoto dheer oo biyaha ah 800-1,200m) ilaa terminaal ku yaal xeebta Norway. Dhuumaha 38 km waxaa ku jira qayb kor u kac ah oo firfircoon (2 km, 25.4mm WT) iyo marin xeebeed oo dhex mara dhul dhagax ah (4 km, 30mm WT saxan la duubay).
Caqabadaha Farsamada iyo Xalalka:
● Iska caabbinta burburka biyaha qotoda dheer– Qoto dheer oo biyaha ah ilaa 1,200m waxay keentaa cadaadis dibadeed oo ah 12.5 MPa. Tuubada UOE ee 24″ × 22.2mm ayaa loo baahan yahay si ay u buuxiso cadaadiska burburka ≥ 25 MPa (qodobka badbaadada 2). Tuubooyinka UOE ee ay soo saartay hooyada oo leh qaab wareegsan ≤ 0.2% (lagu cabbiray 0.15-0.18%) iyo cadaadiska harsan ≤ 35% SMYS. Waxaan sameynay falanqayn curiyeyaal xaddidan (FEA) oo ku saabsan xuduudaha wax soo saarka waxaana xaqiijinay tijaabinta cadaadiska burburka laba muunad oo buuxa (lagu gaaray 28.5 MPa iyo 29.2 MPa).
● Adeeg dhanaan leh oo leh H₂S sare– Gaasku wuxuu ka kooban yahay 50 ppm H₂S heerkulka hawlgalka 90°C. Taarikada la doortay ee kaarboon yar (C ≤ 0.07%), taarikada manganese yar (Mn ≤ 1.40%), taarikada sulfur yar (S ≤ 0.002%) oo leh daaweyn kaalshiyam ah. CEV waxaa lagu hayay 0.35-0.38%. PWHT waxaa loo adeegsaday dhammaan tuubooyinka (qoynaya 600°C ± 10°C, waxay hayaan 1.5 saacadood). Adkaanta ka dib PWHT: birta salka ah 78-84 HRB, alxanka 82-86 HRB, HAZ 80-84 HRB. Tijaabooyinka HIC iyo SSC waxay ku dhammaadeen eber dildilaac.
● Adkaanta jabka CTOD ee kor u kaca– Qaybta kor u kaca firfircoon waxay u baahan tahay adkeysi jabka oo sarreeya si ay u adkeysato rarista mowjadaha. Womic waxay samaysay tijaabada CTOD ee birta alxanka iyo HAZ -20°C. Natiijooyinka: birta alxanka 0.35-0.55mm (≥ 0.25mm ayaa loo baahan yahay), HAZ 0.40-0.70mm (≥ 0.30mm ayaa loo baahan yahay). Waxaan sidoo kale sameynay Charpy heerkul hoose -46°C (celcelis ahaan 110J). DNV waxay goob joog ka ahayd dhammaan tijaabooyinka CTOD.
● Dahaarka heerkulka sare (3LPP)– Heerkulka hawlgalka waa 90°C, iyadoo ugu sarreysa uu yahay 110°C inta lagu jiro xidhitaanka. Heerka 3LPE (polyethylene) wuxuu ku kooban yahay 80°C. Dahaarka 3LPP (polypropylene) ee lagu dahaadhay caloosha oo dhumucdiisu tahay 3.5mm (lakabka sare 2.5mm + dhejis 0.5mm + FBE 0.5mm). Dahaarka ayaa laga gudbay tijaabada kala-goynta cathodic ee 110°C (radius kala-goynta ≤ 8mm ka dib 28 maalmood). Xoogga diirka waa 110°C oo lagu cabiray 60 N/cm (ugu yaraan 50 N/cm).
● Dulqaad aad u sarreeya oo loogu talagalay rakibidda duubista– Dhuumaha waxaa lagu rakibay habka loo yaqaan "reelability" (tuubada lagu dul shubay weel giraangireed). Tani waxay u baahan tahay xakamaynta ovality aad u daran (≤ 0.2%) iyo dhererka xoojinta alxanka ≤ 0.5mm. Habka UOE ee Womic wuxuu gaaray ovality 0.15-0.18%. Waxaan dhulka ku ridnay daboolka alxanka ilaa ≤ 0.3mm dherer. Dhammaan tuubooyinka waxay ka gudbeen tijaabo gaar ah oo "reelability" ah: 10 wareeg oo is dulsaaran oo aan dildilaac lahayn.
● Saadka loo aado Norway– Tuubooyinka waxaa laga soo raray Shanghai ilaa Stavanger, Norway iyada oo loo marayo weel jabaya (sida tuubooyinka gaarka ah). Isgoyska Badda Waqooyi ee Jiilaalka wuxuu u baahday baakad ka hortagta qoyaanka. Womic waxay isticmaashay bacaha VCI (uumiga daxalka joojiya) iyo qalajiyaha jelka silica ee gudaha daboolka. Dhammaan 14,000 oo tan ayaa yimid iyada oo aan lahayn daxal ama dhaawac dahaadh ah.
Natiijo:Dhuumaha dhoofinta gaaska ee Balder waxaa la rakibay Q3 2024. Rakibaadda wareejinta (oo ay sameeyeen qandaraasle hormuud ka ah dibadda) waxay soo sheegeen inaysan jirin cillado ku yimid tolmada tuubooyinka ama alxanka inta lagu jiro boolalaynta iyo dejinta. Dhammaan 38 km waxay dhaafeen tijaabada cadaadiska ee salka badda. Macmiilku (oo ah shirkad weyn oo reer Norway ah) wuxuu siiyay Womic Steel "Abaalmarinta Waxqabadka Alaab-qeybiyaha", isagoo xusay "isku dheelitirnaan cabbir oo heer sare ah iyo natiijooyin CTOD ah." Womic hadda waa alaab-qeybiye la ansixiyay oo loogu talagalay laba mashruuc oo dheeraad ah oo isku xidha Badda Waqooyi.
