Ngā Pātai Auau:
P: He aha te rerekētanga i waenga i te ASTM A252 Grade 3 me te API 5L X52 mō te whakapūranga pou?
A: He iti ake te kaha o te Wāhanga 3 (345 MPa, whakaritea ki te 360 MPa o X52) engari he mea hanga motuhake mō te whakatō poupou. He nui ake te ngāwari me te roa o te mahi (20% min) ā, he manawanui ake ki te taumaha pānga i te wā e pēhia ana te hama. Ka taea hoki te whakamahi i te API 5L X52 mō te whakatō poupou, engari ko te Wāhanga 3 te paerewa ahumahi mō ngā poupou turanga i Amerika Te Raki me te maha o ngā kaupapa o te ao.
Q: Ka taea e koe te whakarato i ngā pou roa ake i te 18m?
Āe. Ka taea e mātou te whakarewa i ngā wāhanga maha, 12m, 18m rānei, kia puta ai he roa tae atu ki te 60m. Ka tirotirohia UT 100% ia whakarewa porowhita, ā, ka taea te tirotiro RT mēnā ka tonoa. He mea noa te whakamahi i ēnei pou roa mō ngā pou hau tai (30-50m te roa).
Q: He aha te matotoru mōrahi o te pakitara mō te paipa LSAW Tau 3?
A: He pereti hurihuri he hononga kotahi tae atu ki te 100mm, he hononga takirua tae atu ki te 100mm. Mō te matotoru o te pakitara neke atu i te 100mm (hei tauira, 120mm), tēnā whakapā mai ki a mātou mō te aromatawai kaupapa motuhake. Kua tukuna e mātou he pou 120mm WT mō ngā turanga wai hohonu motuhake.
Q: Me whakamātautau wai ā-pūmau ēnei paipa?
A: Kāore e hiahiatia he whakamātautau wai-pūmau mō te ASTM A252 nā te mea kāore ngā paipa poupou e ārai i te pēhanga. Heoi, ki te hiahia tō kaupapa ki te whakamātautau wai (hei tauira, mō te poupou me te kawe wai), ka taea e mātou te mahi i tēnei me te utu tāpiri.
Q: He aha te paninga e taunakitia ana mō te whakairi pou i te moana?
A: Mō ngā taiao wai moana, he mea noa te whakamahi i te epoxy tāra waro (te matotoru 600-800 microns) me te epoxy maramara karāhe. Mō ngā wāhi tauhiuhi, ka tūtohu mātou i te FBE, i te 3LPE rānei me te ātete ki te pakū. Mō te wai māori, te oneone rānei, he paipa pango noa, he mata hinu rānei te mea e ranea ana.
P: Me pēhea te whakarite kia ora tonu ngā whakarewa i te wā e whiua ana e te hama?
A: Ka whakahaerehia e mātou te 100% UT o te hononga whakarewa me te MPI (tirotiro matūriki aukume) o ngā matimati whakarewa hei kite i ngā kapiti o te mata. Ka whakahaerehia hoki e mātou ngā whakamātautau piko ārahi i runga i ngā tauira whakarewa hei manatoko i te ngāwari. Mō ngā pou taraiwa nui, ka taea hoki e mātou te whakarato whakamātautau pānga Charpy i te 0°C, iti iho rānei.
P: He aha te roanga o te wā arahi mō ngā paipa whakapuru o te taumata 3?
A: Te wā arataki paerewa: 30-45 ngā rā mō ngā diameter ≤ 1,422mm. Mō ngā paipa pereti hurihuri diameter nui (> 1,422mm): 45-60 ngā rā. Mō ngā pou roa kua whakarewaina (tae atu ki te 60m): tāpirihia kia 2-3 wiki mō te whakarewa porowhita me te tirotiro.

Tapeke:30,500 mita (30.5 km) o te pou, tata ki te 14,700 tāne
Ngā Whakatakotoranga:Ngā pito papatahi (tapahanga tapawhā) me te anga whakarara, te paninga epoxy (500 maikorona, momo epoxy tāra waro) hei tiaki i te waikura i roto i te wai parakore o te Hongere kaipuke o Houston. Whakamātautau whakaparaha me whakahau (kāore he pakaru i muri i te whakaparaha 1/3 diameter). Whakamātautau piko ārahi mō te ngāwari o te whakarewa. 100% UT o te hononga whakarewa me te 10% ira RT. MPI o ngā matimati whakarewa. Pānga Charpy i te 0°C (iti rawa 20J, 40-60J noa). Tirotiro tuatoru e SGS.
Taupānga:Te Whanuitanga o te Taunga Ipu o Bayport i te Tauranga o Houston. Ko te kaupapa i uru atu ki te hanga i ngā taunga hou e rua (1,200m te katoa o te pakitara tauranga) me te wāhi rokiroki ipu taha whenua. Ko ngā pou paipa rino hei turanga mō te hanganga papa raima (ngā pou amo kawenga poutū) me ngā pou tautoko parepare (te uta taha). Te hohonutanga o te wai i ngā taunga: 16m.
Ngā Wero Hangarau me ngā Otinga:
●Taiao wai parakaita waikura– He nui te ihirangi pūhaumāota o te Hongere Ship o Houston (10,000-18,000 ppm) me te pH iti (6.5-7.0) nā te rerenga mai o ngā ahumahi. I pania e Womic he paninga epoxy tāra waro (600 microns DFT) me ngā paparanga e rua: he paninga tuatahi (200 microns) + he paninga runga (400 microns). I paahitia e te paninga te whakamātautau rehu tote 3,000 hāora (ASTM B117) me te ngoki < 2mm. I mahia te kitenga hararei i te 3.5kV me te kore he hapa.
●Teitei o ngā ahotea taraiwa i roto i te onepu matotoru– Ko te āhua oneone i te taunga he onepū paru matotoru me ngā uara-N o te whakamātautau urunga paerewa (SPT) o te 30-50. Tata atu ngā taumahatanga o te akiaki puranga ki te 80% o te kaha hua. I whakahaerehia e Womic ngā whakamātautau piko ārahi i runga i ngā tīkitipati whakarewa (te whānui piko 4x te matotoru, 180°) me te kore he pakaru. I whakaratohia hoki e mātou he MPI whakarewa ki ia puranga 50 kia kore ai he pakaru o ngā matimati. I kōrero te kaiwhakatū taraiwa puranga a te kiritaki kāore he whakarewa pakaru i te wā i tāutahia ai ngā puranga 2,100.
●Ngā pou roa mō ngā moenga wai hohonu– Ko te moenga hohonu rawa i hiahiatia kia werohia ngā pou ki te hohonutanga 32m (20m ki roto i te papa moana + 12m ki runga ake i te paru). Ko ngā hononga paerewa 12m me hiahia kia 3 ngā hononga mara mō ia pou. I whakaratohia e Womic he hononga 18m te roa (he hononga kotahi te pereti hurihuri) mō ngā pou 1,067mm me 1,219mm, ka whakaitihia ngā hononga mara mai i te 3 ki te 2 mō ia pou (ka penapena i te 35% o te wā whakarewa). I whakaratohia hoki e mātou he pou 36m te roa mō te pūnaha ārai (kāore he hononga e hiahiatia) mā te whakarewa i ngā wāhanga e rua 18m te roa mai i te pito ki te pito me te SAW uru katoa me te 100% UT.
●Te pakari o te pānga mō te taraiwa hotoke– Ka heke pea te pāmahana hotoke o Houston ki te -5°C. Ka tūpono te pakaru o te papa rakau i te pāmahana iti. I tukuna e Womic te Wāhanga 3 me te pakari pāmahana iti kua whakarei ake: Te pānga o te Charpy i te 0°C min 20J (kāore e hiahiatia he whakamātautau pānga mō te paerewa A252). Ngā hua tuturu: 45-65J i te 0°C, 35-50J i te -10°C. I whakaurua tēnei e te kiritaki hei whakaritenga kāore i te whakahauhia engari he whakaritenga whai hua.
●Tukunga tika i te wā tika– He iti noa te wāhi whakatakoto o te papa hanga (8,000 mita pūrua anake). E whā ngā tukunga i whakaritea e Womic (tata ki te 3,700 tāne ia) mō ngā marama e 5. I tukuna ngā paipa mā te kaipuke pakaru-rahi mai i Shanghai ki Houston, kātahi ka haria ki ngā taraka i roto i ngā puranga o te 200 tāne i ia 2 wiki. I mahi tahi te tīma whakahaere waka a Womic me te mana whakahaere tauranga ki te whakarite i te tango me te whakahaere i te uta taraka, me te karo i te rokiroki ki te tauranga. I tae mai ngā tukunga katoa i roto i te ±3 rā mai i ngā rā kua whakaritea.
●Te whakatutukitanga i ngā whakaritenga whakakorenga mō Buy America– I hiahiatia he whakakorenga mō te maitai o tāwāhi i roto i te kaupapa Tauranga o Houston nā te mea kāore i taea e te hanga o roto o Amerika te whakatutuki i te wātaka. I whakaratohia e Womic ngā tuhinga taipitopito tae atu ki ngā tiwhikete mira, te whenua i ahu mai ai, me te whai i ngā rauemi. I whakaaetia te whakakorenga, ā, i tukuna katoatia ngā 14,700 tana o ngā maitai ki te Tari Tāke o Amerika me te kore he whakaroa.
● Hua:I oti te whakawhānui i te Tauranga Ipu o Bayport i te hauwhā tuatoru o te tau 2024, i mua i te wā i whakaritea. I paahitia e ngā pou paipa rino katoa e 2,100 te whakamātautau kawenga (whakamātautau kawenga tūmau i runga i te 5% o ngā pou: te taunga < 10mm i te 2x kawenga hoahoa). I kōrero te mana whakahaere tauranga kāore he pakaru o ngā pou, kāore hoki he take paninga. I whiwhi a Womic Steel i te tohu "Supplier Performance Excellence" mai i te kaiwhakatū whānui (he kamupene miihini ā-iwi nui o Amerika). Kei te whakahaerehia te taunga inaianei, e whakahaere ana i te 1.5 miriona TEU ia tau.
