Q: He aha ka uhi i ʻōlelo ʻia no ke kila kūkulu waho?
A: No ka hoʻolaha ʻana i waho, ʻo ka uhi primer (epoxy waiwai i ka zinc, 60-80 microns) ka mea maʻamau no ka pale manawa pōkole i ka wā o ke kūkulu ʻana. No ka pale mau loa me ka ʻole o ka pena ʻana, ʻoi aku ka maikaʻi o ka galvanizing hot-dip (85-100 microns) no nā wahi hoʻopilikia. No nā noi o loko, ua lawa ka ʻili i ʻaila ʻia a i ʻole ka primer liʻiliʻi.
Q: He aha ka manawa alakaʻi maʻamau no ka paipu kūkulu S355JRH LSAW?
A: Ka manawa alakaʻi maʻamau: 30-45 mau lā no nā nui JCOE/UOE. No ka pā kaumaha i ʻōwili ʻia (> 50mm): 45-60 mau lā. No ka hoʻopau ʻana i hoʻopaʻa ʻia a me ka lepo: e hoʻohui i 2 mau pule. No ka galvanizing wela-dip: e hoʻohui i 1-2 mau pule ma muli o ka papa hana ʻauʻau.

Nānā ʻaoʻao ʻekolu e TÜV Rheinland. Pono nā paipu āpau i ka pololei ≤ 0.15% (ʻoi aku ka paʻakikī ma mua o ka maʻamau 0.2%).
Noi:ʻO ke kahua pāʻani ʻo Al Wakrah (i ʻike ʻia hoʻi ʻo Al Janoub Stadium), kekahi o nā wahi no ka FIFA World Cup 2022. ʻO ke kūkulu ʻana o ka hale he ʻupena kaula i hoʻopaʻa ʻia me ke apo hoʻopaʻa kila a me nā trusses radial. Ua hoʻohana ʻia nā paipu LSAW no ke apo hoʻopaʻa nui (1,016mm OD) a me nā radial truss chords (813mm, 610mm, 508mm). ʻO ke anawaena o ka hale ma kahi o 200m a uhi i 42,000 mau noho.
Nā Pilikia ʻenehana a me nā Hoʻonā:
● Ke koi wili kila i hōʻike ʻia ma ke ʻano he hale– ʻIke ʻia ke ʻano o ka hale o ke kahua pāʻani mai loko a i waho. Ua koi ka mea kūʻai aku i nā pāpale weld e wili ʻia i ke kino paipu no ka helehelena maʻalahi. Ua hana ʻo Womic i ka wili weld me ka hoʻohana ʻana i nā mīkini wili orbital automated a ukali ʻia e ka hoʻopau lima. Ua nānā ʻia kēlā me kēia weld no ka maʻalahi (ʻoʻoleʻa o ka ʻili Ra ≤ 6.3μm). Ua hoʻohui kēia i 2 mau pule i ka hana ʻana akā ua loaʻa ka hoʻopau aesthetic i makemake ʻia.
● Koi pololei kiʻekiʻe– Pono ke apo hoʻopaʻa i nā paipu me ke kū pololei ≤ 0.15% (ʻae ʻia ka 0.2%) e ke ʻano maʻamau EN 10219. Ua hoʻohana ʻo Womic i nā kaʻina hana UOE a me JCOE me ka hoʻonui mechanical e hoʻokō i ke kū pololei o 0.08-0.12%. Ua ana ʻia kēlā me kēia paipu ma kahi papa kū pololei (hoʻonohonoho laser). Ua hoʻopololei ʻia nā paipu ma waho o ka hoʻomanawanui me ka hoʻohana ʻana i kahi mīkini paʻi hydraulic.
● Uhi mua no ke kaiapuni wao nahele– He kiʻekiʻe ka mahana ma Qatar (a hiki i ka 50°C), kiʻekiʻe ka makū (a hiki i ka 85% i ka hoʻoilo), a me ke one ea. Ua hoʻopili ʻia ka primer epoxy waiwai zinc (60 microns) i nā paipu āpau. Ua hala ka uhi ʻana i ka hoʻāʻo pīpī paʻakai (1,000 hola, ASTM B117) me ka emi ma mua o 2mm creep. ʻIke ʻia ka Holiday ma 2kV. Ana ʻia ka hoʻopili ʻana ma 8 MPa (min 5 MPa).
● Nā lokika paʻakikī i ka wā o ke kūkulu ʻana o FIFA– He papa hana paʻa ko ke kūkulu ʻana i ke kahua pāʻani (2020-2021). Ua hāʻawi ʻo Womic i nā paipu i 4 mau ukana (ʻo kēlā me kēia 800-1,000 tons) ma luna o 8 mau mahina. Ua hoʻouna ʻia nā paipu mai Shanghai a i Hamad Port (Doha), a laila ua lawe ʻia i 45km i ke kahua pāʻani. Ma muli o nā kapu COVID-19, ʻaʻole hiki i nā mea nānā ponoʻī o Womic ke hele. Ua hoʻonohonoho mākou i ka nānā ʻana mamao ma o ka hānai wikiō ola (TÜV pūnaewele). Ua ʻae ʻia nā 3,480 tons āpau ma kahi mamao.
● Paʻakikī o ka hopena no ka hiki ke haʻahaʻa ka mahana o ka ambient– ʻOiai ua wela ʻo Qatar, hiki i nā pō i ka hoʻoilo ke hāʻule i ka 10°C, a ua hōʻike ʻia ke ʻano o ka hale. Pono ʻo EN 10219 S355JRH i ka hopena Charpy ma 0°C (27J min). Ua hoʻokō ʻo Womic i 80-120J, ʻoi aku ma mua o ke koi. Ua hoʻokomo ʻia nā hōʻike hoʻāʻo i loko o ka pūʻolo CE DoP.
●Hopena:Ua wehe ʻia ke kahua pāʻani ʻo Al Wakrah i ka makahiki 2022 a ua mālama i ʻeono mau pāʻani World Cup. Ua mahalo nui ʻia ke kūkulu ʻana o ka hale kila no kona hoʻolālā nani. Ua hōʻike ka mea hana (kahi mea hana kila ʻEulopa alakaʻi) ʻaʻohe hemahema weld i ka wā o ke kūkulu ʻana. Kūpono loa nā paipu LSAW āpau ma kahi me ka hana hou ʻole. Ua loaʻa iā Womic Steel kahi leka mahalo mai ka mea hana nui no ka "pololei maikaʻi loa o ka dimensional a me ka hoʻopau weld." Ke hoʻomau nei ke kahua pāʻani i ka hana ma ke ʻano he wahi haʻuki a me nā hanana he nui.
