Letšoao la CE ka Phatlalatso ea Ts'ebetso. Tlhahlobo ea motho oa boraro ke TÜV Rheinland. Liphaephe tsohle li hloka ho otloloha ≤ 0.15% (e thata ho feta 0.2%).
Kopo:Lebala la Lipapali la Al Wakrah (le tsejoang hape e le Lebala la Lipapali la Al Janoub), e 'ngoe ea libaka tsa Mohope oa Lefatše oa FIFA oa 2022. Sebopeho sa marulelo se entsoe ka letlooa la thapo le hatelletsoeng le nang le lesale la khatello ea tšepe le li-trusses tsa radial. Liphaephe tsa LSAW li sebelisitsoe bakeng sa lesale le ka sehloohong la khatello (1,016mm OD) le li-chord tsa radial truss (813mm, 610mm, 508mm). Marulelo a bophara ba hoo e ka bang 200m 'me a koahela litulo tse 42,000.
Liphephetso tsa Tekheniki le Litharollo:
● Tšepe e pepesitsoeng ea meralo - tlhoko ea ho sila ka weld– Sebopeho sa marulelo a lebala la lipapali se bonahala kahare le kantle. Moreki o ne a hloka hore dikoahelo tsa weld di bewe fatshe mmeleng wa phaephe bakeng sa ponahalo e boreledi. Womic o ne a sila weld a sebedisa mechini e iketsang ya ho sila ya orbital e latelwang ke ho qeta ka letsoho. Weld ka nngwe e ile ya hlahlojwa bakeng sa boreledi (boreledi ba bokahodimo Ra ≤ 6.3μm). Sena se ekeditse dibeke tse 2 tlhahisong empa sa fihlella qetello e hlokahalang ya botle.
● Tlhokahalo e phahameng ea ho otloloha– Lesale la kgatello le ne le hloka diphaephe tse otlolohileng ≤ 0.15% (EN 10219 e tlwaelehileng e dumella 0.2%). Womic e sebedisitse mekgwa ya UOE le JCOE ka katoloso ya mechini ho fihlella ho otloloha ha 0.08-0.12%. Phaephe ka nngwe e ne e lekantswe tafoleng ya ho otloloha (ho otloloha ha laser). Diphaephe tse sa mamelleng di ne di otloloha ho sebediswa mochine wa hydraulic.
● Sekoahelo sa pele bakeng sa tikoloho ea lehoatata– Qatar e na le mocheso o phahameng (ho fihlela ho 50°C), mongobo o phahameng (ho fihlela ho 85% nakong ea mariha), le lehlabathe le moeeng. Ho ile ha sebelisoa primer ea epoxy e nang le zinc e ngata (60 microns) liphaepheng tsohle. Ho koahela ho fetile teko ea spray ea letsoai (lihora tse 1,000, ASTM B117) ka ho kheloha ho ka tlase ho 2mm. Ho lemoha matsatsi a phomolo ho 2kV. Ho khomarela ho lekantsoe ho 8 MPa (bonyane 5 MPa).
● Tsamaiso e rarahaneng ea thepa nakong ea fensetere ea kaho ea FIFA– Kaho ea lebala la lipapali e ne e e-na le kemiso e thata (2020-2021). Womic e ile ea tlisa liphaephe ka thepa e 4 (e 'ngoe le e 'ngoe e ne e le lithane tse 800-1,000) ka likhoeli tse 8. Liphaephe li ile tsa romeloa ho tloha Shanghai ho ea Hamad Port (Doha), eaba li tsamauoa ka literaka tse 45km ho ea sebakeng sa lebala la lipapali. Ka lebaka la lithibelo tsa COVID-19, bahlahlobi ba Womic ba ne ba sa khone ho tsamaea. Re ile ra hlophisa tlhahlobo ea lipaki tse hole ka video e phelang (TÜV inthaneteng). Lithane tsohle tse 3,480 li ile tsa amoheloa hole.
● Matla a ho ba le tšusumetso bakeng sa mocheso o ka tlase o ka bang teng– Leha Qatar e chesa, bosiu nakong ea mariha bo ka theohela ho 10°C, 'me sebopeho sa marulelo se pepesitsoe. EN 10219 S355JRH e hloka hore mocheso oa Charpy o be ho 0°C (27J min). Womic e fihletse 80-120J, e leng se fetang tlhoko. Litlaleho tsa liteko li kenyelelitsoe sephutheloana sa CE DoP.
●Sephetho:Lebala la Lipapali la Al Wakrah le butsoe ka 2022 mme la tšoara lipapali tse tšeletseng tsa Mohope oa Lefatše. Sebopeho sa marulelo a tšepe se rorisitsoe haholo ka moralo oa sona o motle. Rakonteraka (moetsi ea ka sehloohong oa tšepe oa Europe) o tlalehile hore ha ho na liphoso tsa ho tjheseletsa nakong ea ho emisoa. Liphaephe tsohle tsa LSAW li ile tsa lekana hantle sebakeng seo ntle le ho lokisoa bocha. Womic Steel e fumane lengolo la teboho ho tsoa ho rakonteraka ea ka sehloohong bakeng sa "ho nepahala ho hoholo ha litekanyo le qetello ea ho tjheseletsa." Lebala la lipapali le ntse le tsoela pele ho sebetsa e le sebaka sa lipapali le liketsahalo tse sebelisoang ka bongata.
