1. Womic Steel: Nā Mana Hana a me ka Ikaika o ka ʻOihana
Hoʻokele ʻo Womic Steel Group i nā laina hana LSAW he nui i hiki ke hana i nā paipu kūkulu ASTM A500 Grade C. ʻO ka A500 Grade C kahi paipu kūkulu kila kalapona i hoʻopaʻa ʻia i ke anu (ʻo ka "anuanu i hoʻokumu ʻia" e pili ana i ka mahana hoʻokumu, ʻaʻole ka mālama wela ma hope o ka hoʻopaʻa ʻana). He kūpono ke kaʻina hana LSAW no nā ʻāpana kūkulu poepoe nui ma mua o ka hiki o ka ERW a i ʻole nā wili seamless.
●Laina JCOE:No nā anawaena 406mm - 1,422mm (16″–56″), ʻo ka mānoanoa o ka paia a hiki i 50.8mm. Kūpono no nā kolamu hale a me nā lālā truss alahaka.
● Laina UOE:No nā anawaena 508mm - 1,220mm (20″–48″), ʻo ka mānoanoa o ka paia a hiki i ka 40mm. Hoʻopuka i ka poepoe kiʻekiʻe no ke kila hoʻolālā i hōʻike ʻia.
● Pā ʻōwili (Hui Hoʻokahi):No nā anawaena 600mm - 2,500mm (24″–98″), ʻo ka mānoanoa o ka paia mai 25mm a hiki i 80mm. Kūpono no nā kolamu paia kaumaha a me nā wāwae o ka hale kiaʻi hoʻoili.

● Nā koi ʻāpana ōlaʻi - ductility a me ka paʻakikī– Aia ʻo Los Angeles ma ka Māhele Hoʻolālā Seismic D (kiʻekiʻe ka pilikia seismic). ʻAʻole koi pinepine ʻia ka hoʻāʻo hopena no ka ASTM A500 Grade C. Ua hoʻohui ka ʻenekinia kūkulu i ka koi hopena Charpy o 27J ma 0°C. Ua koho ʻo Womic i nā papa me ke kalapona i kāohi ʻia (0.20-0.22%) a me ka manganese (1.15-1.25%) a ua hoʻokō i ka 60-90J ma 0°C, ʻoi aku ma mua o ke koi.
●Nā ʻāpana tapered nui– Ua hoʻopololei ʻia kekahi mau wāwae hale kiaʻi (ʻano cone). Ua hāʻawi ʻo Womic i nā paipu pololei a laila hana ʻia e ka mea hana i nā ʻāpana hoʻopololei. Ua hāʻawi mākou i ka mana ovality paʻa (≤ 0.5%) e hoʻomaʻalahi i ke kaʻina hana hoʻopololei. Ua hōʻailona ʻia nā paipu me nā laina kuhikuhi e hōʻoia i ka hoʻopili like ʻana.
●Uhi mua no ke kaiapuni kahakai– Aia ke kahua pāʻani ʻo SoFi ma 5 km mai ka Moana Pākīpika mai, me ka paʻakai i pīpī ʻia. Ua hoʻopili ʻia ka primer epoxy waiwai i ka zinc (60 microns) i nā paipu āpau. Ua hala ka uhi ʻana i 1,000 hola o ka hoʻāʻo paʻakai pīpī (ASTM B117) me ka emi ma mua o 2mm ke kolo mai ka mea kākau. ʻIke ʻia ka lā hoʻomaha ma 2kV me ka ʻole o nā hemahema.
●Logistics i ke kahua kūkulu hana– ʻO ka hoʻomohala ʻana o Hollywood Park kekahi o nā papahana kūkulu kūlanakauhale nui loa ma ʻAmelika Hui Pū ʻIa. Pono e hoʻonohonoho ʻia ka lawe ʻana o 2,340 tone o nā paipu anawaena nui. Ua hāʻawi ʻo Womic i nā paipu i 6 mau ukana ma luna o 8 mau mahina, i hoʻonohonoho ʻia e hōʻea ma mua o ke kau ʻana. Ua hoʻouna ʻia nā paipu mai Shanghai a i ke awa o Los Angeles, a laila lawe ʻia i 8 km i ke kahua. Ua hoʻohana mākou i nā ipu pālahalaha no nā paipu 1,016mm a me 1,220mm e pale aku i ka hōʻino ʻia.
●Nā koi o US Buy America– Ua koi ka papahana i kahi hoʻokuʻu no ke kila haole no ka mea ʻaʻole hiki i nā hale wili kūloko o ʻAmelika Hui Pū ʻIa ke hana i nā anawaena nui (1,220mm) i ka mānoanoa o ka paia i koi ʻia i loko o ka papa kuhikuhi. Ua hāʻawi ʻo Womic i nā palapala piha e pili ana i nā palapala hōʻoia o ka hale wili, ka ʻāina kumu, a me ka hiki ke hahai ʻia nā mea. Ua ʻae ʻia ka hoʻokuʻu e ka mea nona.
●Hopena:Ua hoʻopau ʻia ke kūkulu ʻana o nā hale kiaʻi hoʻoili i ka makahiki 2022. Ua lilo lākou i mea i ʻike ʻia o ka paʻakikī o ke kahua pāʻani ʻo SoFi. Ua hōʻike ka mea hana hana ua kūpono nā paipu LSAW āpau me ka hana hou ʻole ʻia. Ua loaʻa i ka hoʻopau kila i hōʻike ʻia ka mahalo mai ka mea kākau hale. Mai ia manawa ua kono ʻia ʻo Womic Steel e kūʻai i nā papahana kila hoʻolālā hou ma ʻAmelika Hui Pū ʻIa.
