● Raad-raac buuxa laga bilaabo lambarka kulaylka saxanka ilaa tuubada la dhammeeyey (lambarka kulaylka ayaa lagu shaabadeeyey tuubo kasta)
● In ka badan 3,000 km oo dhuumaha X52 ah oo la keenay adduunka oo dhan iyadoo aan wax cillad ah lagu samaynayn shaqada gudaheeda
Su'aalaha Badiya La Weydiiyo:
S: Waa maxay faraqa ugu weyn ee u dhexeeya X52 PSL1 iyo PSL2 ee tuubada LSAW?
A: PSL2 waxay leedahay xadad adag oo ka kooban kiimiko (C, P, S oo hooseeya), adkaanta saameynta Charpy ee qasabka ah (ugu yaraan 27J @ 0°C ama ka hooseeya), xadka ugu badan ee adkaanta (90 HRB), waxayna u baahan tahay NDT adag (100% UT marka loo eego booska UT ee PSL1). Tuubooyinka gaaska ee cadaadiska sare leh, adeegga badda, ama dhanaan, PSL2 waa qasab. Khadadka biyaha ama saliidda cadaadiska hooseeya, PSL1 waa la aqbali karaa oo dhaqaale ahaan ka wanaagsan.
S: Ma ku siin kartaa X52 tijaabo saameyn heerkul hoose leh oo loogu talagalay mashaariicda arctic?
J: Haa. Waxaan bixinaa X52 PSL2 oo leh tijaabada saameynta Charpy ee -46°C (ugu yaraan 27J) iyo DWTT oo ah -20°C (ugu yaraan 85% aagga jarista). Waxaan siinay heerka arctic X52 mashaariicda Kanada iyo Ruushka. Fadlan sheeg heerkulka tijaabada iyo tamarta loo baahan yahay markaad wax weydiineyso.
S: Waa maxay dhumucda derbiga ugu badan ee aad u soo saari karto X52 LSAW?
J: Habka JCOE ugu badnaan 50.8mm, habka UOE ugu badnaan 40mm, saxanka duuban tolmo hal mar ah ilaa 70mm, saxanka duuban tolmo labanlaab ah ilaa 80mm. Dhumucda derbiga ka baxsan 50.8mm, PWHT waa qasab. Dhawaan waxaan bixinnay X52 1,600mm OD × 70mm WT mashruuc biyo-ku-shubid cadaadis sare leh oo ka socda Cumaan.
S: Sidee baad u xakameysaa adkaanta adeegga dhanaan ee X52?
A: Waxaan xakameynaa isku-dhafka kiimikada (CEV ≤ 0.40% adeegga dhanaan, ka hooseeya heerka caadiga ah 0.43%), waxaan xakameynaa gelinta kulaylka inta lagu jiro alxanka SAW (≤ 3.0 kJ/mm), waxaanan isticmaalnaa PWHT dhumucda derbiga ≥ 20mm. Adkaanta ka dib PWHT badanaa waa 78-85 HRB biraha salka ah iyo 82-88 HRB alxanka. Waxaan bixinaa dukumeentiyo dhammaystiran oo ku saabsan marin-haweedka adag.
S: Ma bixisaa kormeer dhinac saddexaad ah oo loogu talagalay tuubooyinka X52 LSAW?
J: Haa. Waxaan la shaqeynaa SGS, BV, TÜV, DNV, ABS, iyo LR. Kormeerka waxaa lagu sameyn karaa warshadeenna inta lagu jiro wax soo saarka, iyadoo ay goobjoog ka yihiin wakiilka macmiilka ama hay'adda dhinac saddexaad. Waxaan soo saarnaa shahaadooyinka EN 10204 Nooca 3.2 marka la codsado.
S: Waa maxay waqtiga caadiga ah ee hogaanka ee biibiilaha X52 LSAW?
J: Waqtiga caadiga ah ee hogaaminta: 30-45 maalmood PSL1, 45-60 maalmood PSL2 oo leh tijaabinta adeegga dhanaan. Dalabyada degdega ah (20-30 maalmood) waxay suurtogal u yihiin tiro yar (<500 tan). Dalabyada aadka u waaweyn (>10,000 tan), waqtiga hogaaminta wuxuu socon karaa ilaa 75 maalmood iyadoo ku xiran helitaanka saxanka.
S: Ma ku siin kartaa X52 dahaadh 3LPE ah iyo dahaadh miisaan shub ah oo loogu talagalay dhuumaha badda?
J: Haa. Waxaan bixinaa dahaadh 3LPE ah sida ku cad ISO 21809 (dhumucda guud ee 2.5-3.5mm) waxaana isku dubaridi karnaa dahaadh miisaan shub ah (dhumucda 40-120mm, cufnaanta 2,400-3,050 kg/m³) barxadda dahaarka ee lammaanahayaga ee Tianjin. Waxaan siinay X52 dahaarka badda ah mashaariicda Vietnam, Indonesia, iyo Bariga Dhexe.
Tixraaca Mashruuca - Dhuumaha Dhoofinta Saliida Cayriin ee Bariga Afrika
Dalka:Uganda / Tanzania (Dhuunta Saliidda Ceyriin ee Bariga Afrika – EACOP)
Heerka & Darajada:API 5L X52 PSL2 (adeeg dhanaan, oo leh HIC iyo SSC test)
Cabbirka iyo Tirada:
● OD 610mm (24″) × Miisaan 12.7mm – 48,000 mitir (qiyaastii 7,200 tan) oo ay soo saartay habka UOE
● OD 610mm (24″) × Miisaan 15.9mm – 12,000 mitir (qiyaastii 2,400 tan) oo ay soo saartay habka UOE (derbi qaro weyn oo loogu talagalay isgoysyada webiyada)
● OD 914mm (36″) × WT 19.0mm – 8,500 mitir (qiyaastii 3,400 tan) oo ay soo saartay habka JCOE ee loogu talagalay khadadka bamka ee loo maro
Wadarta:68,500 mitir (68.5 km), qiyaastii 13,000 tan
Tilmaamaha:Dahaarka 3LPE ee dibadda (dhumucda guud ee 3.0mm) halkii ISO 21809, dhammaadka godan 30° / 1.6mm wejiga xididka, baaritaanka hydrotest 11.5 MPa (cadaadiska naqshadeynta 8.5 MPa). Saamaynta Charpy ee qasabka ah 0°C (ugu yaraan 27J, la gaaray 85-120J). HIC halkii NACE TM0284 Xalka A, 96h - aqbalaad: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. SSC halkii NACE TM0177 Habka A, 720h - lama oggola dildilaac. PWHT ayaa loo adeegsaday dhammaan tuubooyinka leh WT ≥ 15.9mm.
Codsiga:Dhuumaha dhoofinta saliidda cayriin ee laga soo dhoofiyo Uganda (gobolka Hoima) ilaa dekedda Tanga ee Tanzaniya ee Badweynta Hindiya. Dhererka guud ee dhuumaha ayaa ah 1,443 km. Womic Steel waxay bixisay 68.5 km wadarta guud, oo ay ku jiraan qaybo dhex mara meelaha duurjoogta xasaasiga ah iyo isgoysyada waaweyn ee wabiyada.
Caqabadaha Farsamada iyo Xalalka:
● U hoggaansanaanta adeegga dhanaan ee saliidda cayriin ee H₂S– Saliidda Uganda waxay ka kooban tahay H₂S milmay ilaa 15 ppm oo ay ku jirto biyo. Tijaabo adag oo HIC iyo SSC ah ayaa loo baahday. Womic waxay samaysay tijaabinta aqoonta 15 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 ah oo dusha sare ah. Waxaan tan ku gaarnay annagoo CEV ≤ 0.38% (oo aad uga hooseeya xadka PSL2 ee 0.43%) iyo adeegsiga PWHT dhammaan tuubooyinka ka sarreeya 12.7mm WT, inkastoo API 5L uusan ku qasbin PWHT inuu ka hooseeyo 25.4mm. Kormeeraha macmiilka (SGS) wuxuu goob joog ka ahaa dhammaan tijaabooyinka.
● Caqabadaha deegaanka ee aagga duurjoogta ah– Dhuunta ayaa dhex marta laba kayd oo qaran oo xayawaan ah. Dhaawaca dahaarka inta lagu jiro rakibidda way adkaan doontaa in la hagaajiyo sababtoo ah marin u helid xaddidan. Womic waxay marisay lakab allabari ah oo polyethylene ah (0.5mm dheeraad ah oo korkiisa ah 3LPE-ga caadiga ah) si ay u noqoto jaakad u adkaysata xoqidda. Waxaan sidoo kale sameynay 100% ogaanshaha fasaxa 7kV (heerka caadiga ah waa 5kV) si loo hubiyo fasaxyada dahaarka eber. Xoogga diirka ayaa lagu tijaabiyay 250 N/cm heerkul ah 25°C, 150 N/cm heerkul ah 70°C.
● Isgoysyada wabiga oo u baahan derbi qaro weyn– Shan meelood oo waaweyn oo laga gudbo wabiyada (qaybaha webiga ee Nile) waxay u baahnaayeen WT 15.9mm halkii ay ka ahaan lahaayeen 12.7mm si loo helo iska caabin dheeraad ah oo burbur iyo u-qallajin ah inta lagu jiro rakibidda sagbend. Tuubooyinkan derbiga ee qaro weyn, waxaan u isticmaalnay habka UOE si loo helo wareegsan wanaagsan (±0.2% OD) si loo hubiyo alxanka wareegga goobta ee lagu kalsoonaan karo ee qaybaha isgoyska. Uvality-ga waxaa lagu cabiray 0.15-0.18%, oo aad uga hooseeya xadka 0.5%.
● Saadaasha dhulka ee masaafada dheer– Tuubooyinka waxaa laga soo raray Shanghai ilaa dekedda Dar es Salaam (Tanzania), ka dibna waxaa la geeyay 1,200 km si loo gaarsiiyo dhuumaha Uganda. Xaaladaha waddooyinka ee galbeedka Tanzania waxaa ka mid ah qaybo aan laami lahayn. Womic waxay samaysay qorshe gaar ah oo shixnad ah: dherer ahaan 12m oo keliya (ma jiraan 18m oo isku-xidh ah qaybta Uganda) si loogu xiro gawaarida xamuulka qaada ee caadiga ah. Tuubo kasta waxaa si gaar ah loogu xiray wadhafyo la sudhay. Waxaan siinnay jaantusyada rarista iyo tababar shirkadda xamuulka qaada ee maxalliga ah. Tuubooyinka ma jiraan wax dhaawac ah intii lagu jiray gaadiidka dhulka ee 1,200 km.
● Dukumenti adag iyo raad-raac– Mashruucu wuxuu u baahnaa shahaadooyin EN 10204 Nooca 3.2 ah lambar kasta oo kuleyl ah, iyadoo si buuxda loo raadraaci karo laga bilaabo saxan ilaa tuubo dhammaystiran. Womic waxay u xilsaartay kontaroole dukumenti oo gaar ah oo la socda dhammaan 68.5 km ee tuubooyinka. Tuubo kasta waxaa lagu shaabadeeyay lambarka kulaylka, lambarka tuubooyinka, iyo isku-duwayaasha GPS-ka ee wax soo saarka. Kooxda QA ee macmiilka ayaa laba jeer hubiyay xaruntayada intii lagu jiray wax soo saarka; labada baaritaanba waxay ku dhammaadeen eber aan waafaqsanayn.
Natiijo:Dhuumaha Saliidda Ceyriin ee Bariga Afrika (EACOP) ayaa loo qorsheeyay in la dhammeeyo farsamada rubuca labaad ee 2025. 13,000 oo tan oo tuubooyinka X52 PSL2 ee Womic Steel ayaa la keenay muddo 8 bilood ah (soo-saarkii ugu horreeyay Oktoobar 2023, soo-saarkii ugu dambeeyay Maajo 2024). Dhammaan tuubooyinka ayaa maray kormeer dhinac saddexaad ah oo ay samaysay SGS Tanzania. Macmiilku (urur ka tirsan shirkadaha saliidda caalamiga ah) ayaa soo saaray warqad ammaan ah oo ku saabsan xakamaynta tayada Womic iyo keenista waqtigii loogu talagalay. Womic hadda waa alaab-qeybiye hore u qalma oo loogu talagalay ballaarinta dhuumaha mustaqbalka ee gobolka.
