Su'aalaha Badiya La Weydiiyo:
S: Waa maxay faraqa u dhexeeya EN 10219 S355JRH iyo EN 10210 S355JRH?
A: EN 10219 waa qaybaha godadka qabow ee la alxamay (alxanka iyo sameynta waxaa lagu sameeyaa heerkulka qolka). EN 10210 waa qaybaha godadka kulul ee la dhammeeyay (aan tolnayn ama la alxamayn ka dibna lagu daweeyay kulayl). Tuubooyinka LSAW, EN 10219 waa heerka khuseeya. Qaybaha kulul ee EN 10210 badanaa waa kuwo aan tolnayn ama ERW. Labaduba waxay leeyihiin sifooyin farsamo oo isku mid ah.
S: Ma ku siin kartaa S355J2H (saameyn -20°C) halkii aad ka bixin lahayd S355JRH?
J: Haa. S355J2H waxaa la heli karaa marka la codsado codsiyada heerkulka hooseeya sida dhismayaasha badda ama arctic. Halabuurka kiimikada waa isku mid laakiin leh xadad adag iyo saameynta Charpy ee la hubo -20°C (ugu yaraan 27J). Kharash dheeraad ah ayaa khuseeya.
S: Ma bixisaa calaamadda CE ee tuubooyinka EN 10219?
J: Haa. Womic Steel waxay leedahay shahaadada Xakamaynta Waxsoosaarka Warshadda (FPC) sida waafaqsan EN 10219. Waxaan bixinaa calaamadda CE oo leh Bayaanka Waxqabadka (DoP) ee tuubooyinka lagu iibiyo Aagga Dhaqaalaha Yurub (EEA). Tani waxay hubinaysaa in si habsami leh loo nadiifiyo kastamka iyo aqbalaadda mashruuca.
S: Waa maxay dhererka ugu badan ee galvanizing-ka kulul?
J: Lamaanahayaga galvanizing-ka wuxuu leeyahay dherer qubeys ah oo ah 13.5m. Sidaa darteed, tuubooyinka ilaa 12.5m waa la gelin karaa oo la galvanized karaa si buuxda. Tuubooyinka dhaadheer, waxaan diyaarin karnaa galvanizing qayb ahaan ama waxaan mari karnaa dahaar kale (epoxy-ka zinc-ka hodanka ku ah). Fadlan nala soo xiriir si aad u hesho shuruudaha dhererka gaarka ah.
S: Ma shiidi kartaa qalabka lagu nadiifiyo biraha dhismaha ee la soo bandhigay?
J: Haa. Tuubooyinka qaab-dhismeedka muuqda (tusaale ahaan, tiirarka ku yaal terminaalka garoonka diyaaradaha, qaansooyinka buundooyinka), waxaan ku shiidi karnaa daboolka alxanka SAW si uu ugu habboonaado jirka tuubada. Tani waa hawlgal dheeraad ah waxayna ku daraysaa kharashka iyo waqtiga rasaasta (qiyaastii +15%). Waxaan kugula talineynaa inaad qeexdo shuruudahan wakhtiga dalabka.
S: Dahaarka noocee ah ayaa lagu talinayaa birta qaab-dhismeedka dibadda?
J: Marka la eego bannaanka, dahaarka rinjiga (epoxy-ka zinc-ka hodanka ku ah, 60-80 microns) waa heer loogu talagalay ilaalinta ku meel gaarka ah inta lagu jiro dhismaha. Ilaalinta joogtada ah iyada oo aan rinjiyeyn, galvanizing-ka kulul (85-100 microns) ayaa ugu fiican deegaannada gardarrada leh. Codsiyada gudaha, dusha sare ee saliidda leh ama rinjiga ugu yar ayaa ku filan.
S: Waa maxay waqtiga caadiga ah ee hogaanka ee tuubada qaab-dhismeedka S355JRH LSAW?
J: Waqtiga caadiga ah ee rasaasta: 30-45 maalmood cabbirrada JCOE/UOE. Saxanka la duubay ee derbiga culus (> 50mm): 45-60 maalmood. Dhammaystirka laalaada iyo dhulka: ku dar 2 toddobaad. Galvanization-ka kulul: ku dar 1-2 toddobaad iyadoo ku xiran jadwalka qubeyska.

Qaab-dhismeedka saqafka wuxuu ka kooban yahay shabaq fiilo leh oo leh giraan bir ah oo cadaadis ah iyo trusses radial ah. Tuubooyinka LSAW waxaa loo isticmaalay giraanta cadaadiska ugu weyn (1,016mm OD) iyo chords-ka radial truss (813mm, 610mm, 508mm). Saqafku wuxuu dhererkiisu yahay qiyaastii 200m dhexroor wuxuuna daboolayaa 42,000 oo kursi.
Caqabadaha Farsamada iyo Xalalka:
● Shuruudaha shiididda birta la soo bandhigay ee dhismaha - alxanka– Qaab-dhismeedka saqafka garoonka ayaa laga arki karaa gudaha iyo dibaddaba. Macmiilku wuxuu u baahday daboolo alxan si loogu shubo jirka tuubada si uu u muuqdo mid siman. Womic waxay samaysay alxanka shiididda iyadoo la adeegsanayo mashiinno shiidid wareeg ah oo otomaatig ah oo ay ku xigto dhammaystirka gacanta. Alxan kasta waxaa la baaray si siman (qafiifnimada dusha sare ee Ra ≤ 6.3μm). Tani waxay ku dartay 2 toddobaad wax soo saarka laakiin waxay gaartay dhammaystirka bilicda ee loo baahan yahay.
● Shuruudo toosan oo sare– Giraanta cadaadiska waxay u baahnayd tuubooyin toosan ≤ 0.15% (heerka EN 10219 wuxuu u oggolaanayaa 0.2%). Womic waxay isticmaashay hababka UOE iyo JCOE oo leh ballaarin farsamo si loo gaaro toosan 0.08-0.12%. Tuubo kasta waxaa lagu cabiray miiska toosan (isku-dubaridka laysarka). Tuubooyinka aan dulqaadka lahayn waxaa lagu toosiyay iyadoo la isticmaalayo makiinada cadaadiska biyaha.
● Dahaarka Primer ee deegaanka lamadegaanka– Qatar waxay leedahay heerkul sare (ilaa 50°C), qoyaan sare (ilaa 85% xilliga jiilaalka), iyo ciid hawada ku jirta. Qalabka epoxy-ga ee hodanka ku ah zinc (60 microns) ayaa lagu mariyey dhammaan tuubooyinka. Dahaarka ayaa ka gudbay tijaabada buufinta milixda (1,000 saacadood, ASTM B117) oo leh wax ka yar 2mm oo gurguur ah. Ogaanshaha fasaxa 2kV. Ku dhegganaanta waxaa lagu cabiray 8 MPa (ugu yaraan 5 MPa).
● Saadka adag inta lagu jiro daaqadda dhismaha FIFA– Dhismaha garoonka wuxuu lahaa jadwal adag (2020-2021). Womic waxay keentay tuubooyin 4 shixnadood ah (midkiiba 800-1,000 tan) muddo 8 bilood ah. Tuubooyinka waxaa laga soo raray Shanghai una qaaday Dekedda Hamad (Doha), ka dibna waxaa loo raray 45km goobta garoonka. Sababtoo ah xayiraadaha COVID-19, kormeerayaasha Womic ma aysan safri karin. Waxaan diyaarinay kormeer goob joog ah oo fog ah iyada oo loo marayo quudinta fiidiyowga tooska ah (TÜV online). Dhammaan 3,480 tan waxaa laga aqbalay meel fog.
● Saamaynta adkeysiga heerkulka deegaanka oo hooseeya ee suurtagalka ah– In kasta oo Qatar ay kulul tahay, haddana habeennada xilliga jiilaalka waxay hoos ugu dhici karaan 10°C, qaab-dhismeedka saqafkana waa la soo bandhigay. EN 10219 S355JRH waxay u baahan tahay saameyn Charpy ah 0°C (27J daqiiqo). Womic waxay gaartay 80-120J, taasoo ka sarreysa shuruudaha. Warbixinnada tijaabada waxaa lagu daray xirmada CE DoP.
●Natiijo:Garoonka Al Wakrah ayaa la furay sanadkii 2022 wuxuuna martigeliyay lix kulan oo Koobka Adduunka ah. Qaab-dhismeedka saqafka birta ah ayaa si weyn loogu amaanay naqshaddiisa quruxda badan. Qandaraaslaha (oo ah farsamayaqaan birta Yurub ah oo hormuud ka ah) ayaa sheegay inaysan jirin wax cillado ah oo alxanka ah inta lagu jiro kacsiga. Dhammaan tuubooyinka LSAW waxay si fiican ugu habboon yihiin goobta iyada oo aan wax dib-u-habayn ah la samayn. Womic Steel waxay heshay warqad mahadnaq ah oo ka timid qandaraaslaha ugu weyn "saxnaanta cabbirka iyo dhammaystirka alxanka." Garoonka ayaa sii wada inuu u shaqeeyo sidii goob isboorti iyo dhacdooyin oo badan oo la isticmaalo.
