1. Womic Steel: Ngā Pūkenga Hanga me te Kaha o te Kamupene
He maha ngā raina whakaputa LSAW a Womic Steel Group e āhei ana ki te whakaputa i ngā paipa hanganga ASTM A500 Grade C. Ko te A500 Grade C he ngongo hanganga maitai waro whakarewa matao (ko te "whakaahua matao" e pā ana ki te pāmahana hanga, ehara i te maimoatanga wera i muri i te whakarewa). He pai te tukanga LSAW mō ngā wāhanga hanganga porowhita nui te diameter i tua atu i te kaha o ngā mira ERW, o ngā mira tuimotu rānei.
●Raina JCOE:Mō ngā diameter 406mm – 1,422mm (16″–56″), ko te matotoru o te pakitara tae atu ki te 50.8mm. He pai mō ngā pou hanga me ngā mema o te piriti.
● Raina UOE:Mō ngā diameter 508mm – 1,220mm (20″–48″), ko te matotoru o te pakitara tae atu ki te 40mm. Ka puta he porowhita teitei mō te maitai hoahoanga e kitea ana.
● Pereti Hurihuri (Tuinga Kotahi):Mō ngā diameter 600mm – 2,500mm (24″–98″), ko te matotoru o te pakitara mai i te 25mm ki te 80mm. He pai mō ngā pou pakitara taumaha me ngā waewae o te pourewa tuku.
● Pereti Hurihuri (Tuitui Takirua):Mō ngā diameter 1,200mm – 2,500mm (48″–98″), ko te matotoru o te pakitara tae atu ki te 80mm.
Neke atu i te 300,000 tāne te kaha katoa o te LSAW i ia tau, ā, neke atu i te 80,000 tāne te hanga A500 Grade C i ia tau. Kei a Womic Steel te ISO 9001, ā, ka taea e ia te tuku tirotiro tuatoru mā SGS, BV, TÜV. E mano tāne o te A500 Grade C e tukuna ana mō ngā kaupapa hanganga o Amerika (ngā piriti, ngā papa tākaro, ngā whare ahumahi).

Whenua:Te Hononga o Amerika (Inglewood, California – rohe o te Papa Tākaro SoFi)
Paerewa me te Taumata:ASTM A500 Tau C (me te pānga Charpy tāpiri i te 0°C)
Ngā Ahu me te Rahinga:
OD 610mm (24″) × WT 16.0mm – 2,400 mita (tata ki te 560 tāne) i hangaia mā te tukanga UOE
OD 813mm (32″) × WT 20.0mm – 1,800 mita (tata ki te 700 tāne) i hangaia mā te tukanga JCOE
OD 1,016mm (40″) × WT 25.0mm – 900 mita (tata ki te 550 tāne) i hangaia mā te pereti hurihuri hononga kotahi
OD 1,220mm (48″) × T 30.0mm – 600 mita (tata ki te 530 tāne) i hangaia mā te pereti hurihuri, he hononga kotahi
Tapeke:5,700 mita (5.7 kiromita), tata ki te 2,340 tāne
Ngā Whakatakotoranga:Ngā pito papatahi me te chamfer (mō te whakarewanga o te papa), te taupoki whakarewa kua hurihia ki te whenua (kua kitea te hanganga), te paninga tuatahi epoxy whai konutea (60 microns). Whakamātautau whakatārewatanga me whakahau (kāore he pakaru i te 1/3 diameter o te whakatārewatanga). Whakamātautau piko ārahi mō te ngāwari o te whakarewa. 100% UT o te hononga whakarewa. Pānga charpy i te 0°C (iti rawa 27J, kua tutuki 60-90J). Te tika ≤ 0.15% (he kaha ake i te paerewa A500). Tirotiro tuatoru e SGS USA.
Taupānga:Ngā hanganga pourewa tuku whakapaipai me te mahi e karapoti ana i te papa tākaro SoFi me te whanaketanga o Hollywood Park i Los Angeles. Ko ngā paipa LSAW hei pou poutū matua me te tautoko whakarara mō ngā pourewa tuku "tino" hoahoanga nui (tata ki te 60m te teitei) e tautoko ana i ngā tohu, ngā rama, me te mahi hoki hei tohu whenua hoahoanga. I hiahiatia e te kaupapa he rino kua kitea me te mutunga whakarewa maeneene me te āhua ōrite.
Ngā Wero Hangarau me ngā Otinga:
● Te maitai whakairo whare – te huri me te whakaoti i te whakarewa– E kitea ana ngā pourewa mai i te papa tākaro me ngā rohe e karapoti ana. I mahi a Womic i te huri whakarewa aunoa, ā, i muri mai ka oti ā-ringa kia maeneene te mata (Ra ≤ 6.3μm). I pania anō hoki e mātou he paninga tuatahi ōrite (epoxy whai konutea, he tae hina mārama i tohua e te kaihoahoa). I tirotirohia ia paipa mō te maeneene o te whakarewa e te tīma QA a te kiritaki.
● Ngā whakaritenga mō te rohe rū – te ngāwari me te pakari– Kei roto a Los Angeles i te Kāwai Hoahoa Rū whenua D (he nui te mōrearea rū whenua). Kāore e hiahiatia he whakamātautau pānga mō te ASTM A500 Grade C. I tāpirihia e te miihini hanganga te whakaritenga pānga Charpy o te 27J i te 0°C. I whiriwhiria e Womic ngā pereti me te waro whakahaere (0.20-0.22%) me te manganese (1.15-1.25%), ā, i tutuki i a ia te 60-90J i te 0°C, he nui ake i te whakaritenga.
●Ngā wāhanga whakarara nui– Ko ētahi waewae o te pourewa he mea whakapiko (he āhua kōne). I tukuna mai e Womic ngā paipa tika, kātahi ka hangaia e te kaiwhakatū kia whakapikohia. I whakaratohia e mātou he mana whakahaere porowhita pakari (≤ 0.5%) hei whakahaere i te tukanga whakapiko. I tohua ngā paipa ki ngā rārangi whakatakotoranga hei whakarite kia ōrite te whakarewa.
●Paninga tuatahi mō te taiao takutai moana– Kei te 5 kiromita te tawhiti o te Papa Tākaro SoFi mai i te Moana-nui-a-Kiwa, ā, kei reira te rehu tote. I pania he paninga epoxy whai kiko konutea (60 maikorona) ki ngā paipa katoa. I paahitia e te paninga te whakamātautau rehu tote 1,000 hāora (ASTM B117) me te iti iho i te 2mm te ngoki mai i te kaituhituhi. Te kitenga hararei i te 2kV me te kore he rahunga.
●Ngā mahi kawe ki te papa hanga e mahi tonu ana– Ko te whanaketanga o Hollywood Park tētahi o ngā kaupapa hanga tāone nui rawa atu i te US. Me raupapa te tukunga o ngā paipa whānui nui e 2,340 tana te taumaha. I tukuna e Womic ngā paipa i roto i ngā tuku e 6 i roto i ngā marama e 8, ia tukunga i whakaritea kia tae mai i mua tata tonu o te tāutanga. I tukuna ngā paipa mai i Shanghai ki te Tauranga o Los Angeles, kātahi ka haria ki te taraka mō te 8 km ki te papaanga. I whakamahia e mātou ngā ipu whatanga papatahi mō ngā paipa 1,016mm me te 1,220mm hei karo i te pakaru.
●Ngā whakaritenga a te US Hokona Amerika– I hiahiatia he whakakorenga mō te maitai o tāwāhi i roto i te kaupapa nā te mea kāore i taea e ngā mira o te rohe o Amerika te whakaputa i ngā diameter nui (1,220mm) i roto i te matotoru pakitara e hiahiatia ana i roto i te wātaka. I whakaratohia e Womic ngā tuhinga katoa tae atu ki ngā tiwhikete mira, te whenua taketake, me te whai i ngā rauemi. I whakaaetia te whakakorenga e te rangatira.
●Hua:I oti te hanganga o ngā hanganga pourewa tuku hiko i te tau 2022. Kua noho hei āhuatanga rongonui o te whare takaro SoFi. I kōrero te kaiwhakatū he pai te uru o ngā paipa LSAW katoa, kāore he mahi anō. I whakanuia te whakaotinga maitai e kitea ana e te kaihoahoa. Mai i taua wā kua karangatia a Womic Steel ki te tuku tono mō ētahi atu kaupapa maitai hoahoanga i te US.
