Cabbirka iyo Tirada:
OD 610mm (24″) × Miisaan 16.0mm – 2,400 mitir (qiyaastii 560 tan) oo ay soo saartay habka UOE
OD 813mm (32″) × Miisaan 20.0mm – 1,800 mitir (qiyaastii 700 tan) oo ay soo saartay habka JCOE
OD 1,016mm (40″) × Miisaan 25.0mm – 900 mitir (qiyaastii 550 tan) oo lagu sameeyay tolmo hal saxan ah oo la duubay
OD 1,220mm (48″) × Miisaan 30.0mm – 600 mitir (qiyaastii 530 tan) oo lagu sameeyay tolmo hal saxan ah oo la duubay
Wadarta:5,700 mitir (5.7 km), qiyaastii 2,340 tan
Tilmaamaha:Dhammaadyo siman oo leh chamfer (alxanka dabada), daboolka alxanka dhulka lagu shubo (shuruudaha qaab-dhismeedka ee la soo bandhigay), dahaarka epoxy-ga hodanka ku ah zinc (60 microns).

Codsiga:Qaab-dhismeedka munaaradaha gudbinta ee qurxinta iyo kuwa shaqeynaya ee ku hareeraysan Garoonka SoFi iyo dhismaha Hollywood Park ee Los Angeles. Tuubooyinka LSAW waxay u adeegaan sidii tiirar toosan oo ugu muhiimsan iyo taageero dhinac ah oo loogu talagalay munaaradaha gudbinta ee dhismaha ee "super" (qiyaastii 60m dherer) kuwaas oo taageera calaamadaha, nalalka, iyo sidoo kale inay u adeegaan calaamado dhisme. Mashruucu wuxuu u baahnaa bir la soo bandhigay oo leh dhammaystir siman oo alxan ah iyo muuqaal isku mid ah.
Caqabadaha Farsamada iyo Xalalka:
● Birta la soo bandhigay ee dhismaha - shiididda iyo dhammaystirka alxanka– Munaaradaha waxaa laga arki karaa garoonka iyo agagaarkiisa. Womic waxay samaysay shiidid alxan oo otomaatig ah ka dibna waxaa gacanta lagu dhammeeyay si loo gaaro dusha siman (Ra ≤ 6.3μm). Waxaan sidoo kale marinay dahaar isku mid ah oo loogu talagalay rinjiyeynta (epoxy-ka hodanka ku ah zinc, midab cawlan oo khafiif ah oo uu qeexay naqshadeeyaha). Tuubo kasta waxaa baaray kooxda QA ee macmiilka si loo ogaado simanaanta alxanka.
● Shuruudaha aagga dhulgariirka - dabacsanaanta iyo adkaanta– Los Angeles waxay ku jirtaa Nooca Naqshadeynta Dhulgariirka ee D (khatarta dhulgariirka sare). Heerka ASTM A500 ee C caadi ahaan uma baahna tijaabinta saameynta. Injineerka qaab-dhismeedka ayaa ku daray shuruudaha saameynta Charpy ee 27J heerkul ah 0°C. Taarikada la xushay ee Womic oo leh kaarboon la xakameeyey (0.20-0.22%) iyo manganese (1.15-1.25%) waxayna gaareen 60-90J heerkul ah 0°C, taasoo ka sarreysa shuruudaha.
●Qaybo ballaaran oo wareegsan– Lugaha munaaradaha qaarkood ayaa la jarjaray (qaab koone ah). Womic waxay bixisay tuubooyin toosan oo uu qandaraasluhu sameeyay qaybo godan. Waxaan bixinay xakameyn wareegsan oo adag (≤ 0.5%) si loo fududeeyo habka godan. Tuubooyinka waxaa lagu calaamadeeyay xariiqyo jihooyin si loo hubiyo alxan joogto ah.
●Dahaarka Primer ee deegaanka xeebta– Garoonka SoFi wuxuu ku yaal 5 km u jira Badweynta Baasifigga, iyadoo la soo bandhigay buufin milix leh. 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 ka soo baxay scribe. Ogaanshaha fasaxa 2kV oo aan lahayn wax cillado ah.
●Saadka goobta dhismaha ee firfircoon– Horumarinta Beerta Hollywood waa mid ka mid ah mashaariicda dhismaha magaalooyinka ugu waaweyn ee Mareykanka. Bixinta 2,340 tan oo tuubooyin dhexroor weyn ah ayaa loo baahday in la isku xigxigo. Womic waxay keentay tuubooyin 6 shixnadood ah muddo 8 bilood ah, mid walbana waa la qorsheeyay inuu yimaado wax yar ka hor inta aan la rakibin. Tuubooyinka waxaa laga soo raray Shanghai ilaa Dekedda Los Angeles, ka dibna waxaa loo raray 8 km goobta. Waxaan isticmaalnay weelal fidsan oo loogu talagalay tuubooyinka 1,016mm iyo 1,220mm si looga fogaado waxyeelada.
●Shuruudaha Iibsashada Mareykanka ee Mareykanka– Mashruucu wuxuu u baahday ka dhaafitaan birta qalaad sababtoo ah warshadaha gudaha ee Mareykanka ma soo saari karaan dhexroorka weyn (1,220mm) ee dhumucda derbiga loo baahan yahay jadwalka dhexdiisa. Womic waxay bixisay dukumeentiyo buuxa oo ay ku jiraan shahaadooyinka warshadaha, waddanka ay ka soo jeedaan, iyo raad-raaca agabka. Ka dhaafitaanka waxaa ansixiyay milkiilaha.
●Natiijo:Qaab-dhismeedka munaaradaha gudbinta ayaa la dhammeeyay 2022. Waxay noqdeen astaamo la aqoonsan karo oo ka mid ah dhismaha SoFi Stadium. Qandaraaslaha ayaa sheegay in dhammaan tuubooyinka LSAW ay si fiican ugu habboon yihiin iyada oo aan wax dib-u-habayn ah la samayn. Dhammaystirka birta la soo bandhigay wuxuu ka helay ammaan naqshadeeyaha. Womic Steel tan iyo markaas waxaa lagu martiqaaday inay dalbato mashaariic dheeraad ah oo bir ah oo dhisme ah oo ka dhaca Mareykanka.
