Mafotokozedwe:Malekezero opanda kanthu okhala ndi chamfer (yolumikizira matako), zipewa zolumikizira pansi zothira pansi kupita ku thupi la chitoliro (zofunikira pa zomangamanga), chophimba choyambirira (epoxy wolemera mu zinc, ma microns 60). Mayeso okakamiza ophwanyika, mayeso owongolera, 100% UT ya msoko wolumikizira kuphatikiza 10% RT. Kugunda kwa Charpy pa 0°C (min 27J, kufika pa 80-120J). Chizindikiro cha CE ndi Chidziwitso cha Kuchita Bwino. Kuyang'aniridwa ndi chipani chachitatu ndi TÜV Rheinland. Mapaipi onse amafunikira kulunjika ≤ 0.15% (kokhwima kuposa muyezo 0.2%).

Ntchito:Bwalo la Al Wakrah (lomwe limadziwikanso kuti Al Janoub Stadium), limodzi mwa malo ochitira masewero a FIFA World Cup 2022. Denga lake lili ndi ukonde wolumikizidwa ndi chingwe wokhala ndi mphete yachitsulo yopondereza ndi ma radial trusses. Mapaipi a LSAW adagwiritsidwa ntchito pa mphete yayikulu yopondereza (1,016mm OD) ndi ma radial truss chords (813mm, 610mm, 508mm). Denga lake ndi lalikulu pafupifupi mamita 200 ndipo lili ndi mipando 42,000.

Mavuto ndi Mayankho a Ukadaulo:

● Chitsulo chowonekera pa zomangamanga - chofunikira chopukusira chopukusira– Denga la bwalo lamasewera limawoneka mkati ndi kunja. Kasitomala amafuna kuti zipewa zolumikizira zigwiritsidwe ntchito pansi pa chitoliro kuti ziwoneke bwino. Womic ankagwiritsa ntchito makina olumikizira okha ozungulira kenako n’kumaliza ndi manja. Cholumikizira chilichonse chinayang’aniridwa kuti chione ngati chili chosalala (kulimba kwa pamwamba pa Ra ≤ 6.3μm). Izi zinawonjezera milungu iwiri kuti chipangidwe chikhale chokongola koma chinakwaniritsa kukongola kofunikira.

● Kufunika kowongoka kwambiri– Mphete yokakamiza inkafuna mapaipi okhala ndi kulunjika ≤ 0.15% (standard EN 10219 imalola 0.2%). Womic idagwiritsa ntchito njira za UOE ndi JCOE zokhala ndi kukula kwa makina kuti zikwaniritse kulunjika kwa 0.08-0.12%. Chitoliro chilichonse chinayesedwa patebulo lolunjika (laser alignment). Mapaipi osalolera anawongoleredwa pogwiritsa ntchito makina osindikizira a hydraulic.

● Chophimba choyambirira cha malo achipululu– Qatar ili ndi kutentha kwambiri (mpaka 50°C), chinyezi chambiri (mpaka 85% nthawi yachisanu), ndi mchenga wouluka. Choyambira cha epoxy cholemera mu zinc (60 microns) chinagwiritsidwa ntchito pamapaipi onse. Chophimbacho chinapambana mayeso a mchere (maola 1,000, ASTM B117) ndi kukwera kosakwana 2mm. Kuzindikira kwa tchuthi pa 2kV. Kumatirira kumayesedwa pa 8 MPa (mphindi 5 MPa).

● Zinthu zovuta pa nthawi yomanga nyumba ya FIFA– Kumanga bwalo lamasewera kunali ndi nthawi yochepa (2020-2021). Womic inatumiza mapaipi m'magawo anayi (matani 800-1,000) kwa miyezi 8. Mapaipi anatumizidwa kuchokera ku Shanghai kupita ku Hamad Port (Doha), kenako ananyamula magalimoto 45km kupita kumalo a bwalo lamasewera. Chifukwa cha zoletsa za COVID-19, oyang'anira a Womic sanathe kuyenda. Tinakonza zoti anthu aziona patali kudzera pa kanema wamoyo (TÜV online). Matani onse 3,480 analandiridwa patali.

● Kulimba kwa mphamvu pa kutentha kochepa komwe kungatheke– Ngakhale kuti ku Qatar kumakhala kotentha, usiku nthawi yozizira kutentha kumatha kutsika kufika pa 10°C, ndipo denga limakhala lotseguka. EN 10219 S355JRH imafuna kuti kutentha kwa Charpy kugwere pa 0°C (27J min). Womic idakwanitsa 80-120J, kuposa momwe zimafunikira. Malipoti oyesera adaphatikizidwa mu phukusi la CE DoP.

●Zotsatira:Bwalo la Al Wakrah linatsegulidwa mu 2022 ndipo linachitikira masewera asanu ndi limodzi a World Cup. Denga lachitsulo layamikiridwa kwambiri chifukwa cha kapangidwe kake kokongola. Kontrakitala (katswiri wodziwika bwino wopanga zitsulo ku Europe) adanena kuti palibe vuto lililonse pakulumikiza zitsulo panthawi yomanga. Mapaipi onse a LSAW adagwira bwino ntchito popanda kusinthidwa. Womic Steel idalandira kalata yoyamikira kuchokera kwa kontrakitala wamkulu chifukwa cha "kulondola kwabwino kwambiri komanso kutsirizika kwa zitsulo." Bwaloli likupitilizabe kugwira ntchito ngati malo ochitira masewera ndi zochitika zosiyanasiyana.
