Ngā Whakatakotoranga:Paninga 3LPP o waho (3.5mm) mō te pāmahana teitei (95°C), pito piko 30°/1.6mm, whakamātautau wai i te 18.0 MPa (pēhanga hoahoa 12.5 MPa). Pānga Charpy whakahau i te -20°C (iti rawa 50J, tutuki 100-160J). CTOD i te -20°C: whakarewa whakarewa ≥ 0.25mm, HAZ ≥ 0.30mm (tutuki 0.35-0.55mm). HIC mō ia NACE TM0284 Otinga A, 96h-whakaae: CLR = 0%, CTR = 0%, CSR = 0%. SSC mō ia NACE TM0177 Tikanga A, 720h i te 90% SMYS-Kāore he pakaru. Te pakeke mōrahi 85 HRB. Ka whakamahia te PWHT ki ngā paipa katoa (rumia ki te 590°C ± 10°C, 1.5 hāora). 100% UT me te TOFD me te 20% RT. Tirotiro a te hunga tuatoru e DNV Ahitereiria.

Taupānga:He paipa hau kawa e kawe ana i te hau māori mai i ngā mara o tai (me te ihirangi H₂S o te 15-25 ppm) ki tētahi tipu LNG o uta. Kei roto i te paipa 65 km te roa he wāhanga wai hohonu o raro moana (te hohonu o te wai 200-300m) me tētahi wāhanga o uta i roto i te oneone waikura. Ka mahi te paipa i te 95°C me te 12.5 MPa.

Ngā Wero Hangarau me ngā Otinga:

● Te pāmahana teitei (95°C) me te ratonga kawa -Ko te nuinga o ngā paipa ratonga kawa e mahi ana i raro i te 80°C. I te 95°C, ka whakatakotohia e te NACE MR0175 he herenga pakari ake mō te pakeke me te kōwhiringa rauemi. I whiriwhiria e Womic ngā pereti Mo-alloyed (Mo 0.20-0.25%) me te whakamahi i te paninga 3LPP (polypropylene, kua whakatauria ki te 120°C) hei utu mō te 3LPE (kua herea ki te 80°C). I whakaitihia te pāmahana PWHT ki te 580°C hei karo i te wera nui rawa. Te pakeke i muri i te PWHT: konganuku turanga 78-82 HRB, whakarewa 80-84 HRB-kei roto tonu i te rohe.

● Te whakaritenga HIC kore-pakaru -I hiahiatia e te kiritaki te CLR = 0% (kāore he pakaru HIC). I whakamahia e Womic ngā pereti whanariki tino iti (S ≤ 0.0008%) me te ōwehenga Ca/S 2.2. I muri i te PWHT, i whakaatuhia e te whakamātautau HIC i runga i te 20 tauira (4 mō ia wera) te CLR 0%, CTR 0%, CSR 0%. I whakaatuhia e te whakamātautau hanganga moroiti he sulfides porowhita anake (kāore he MnS roa).

● Te pakari o te pakaru CTOD mō te riser tai moana -I hiahiatia he whakamātautau CTOD mō te wāhanga whakaara (12 km) i te -20°C. I whakahaerehia e Womic te CTOD ki runga i te konganuku whakarewa me te HAZ. Ngā hua: konganuku whakarewa 0.40-0.55mm, HAZ 0.45-0.70mm (neke atu i te 0.25mm/0.30mm). I whakaratohia hoki e mātou ngā taunakitanga mō te tohu tikanga whakarewa katoa (WPQ) mō te whakarewa porowhita mara.

● Te piri o te paninga pāmahana teitei (3LPP) -Me whakamahi te paninga 3LPP i te paninga FBE (epoxy) me te paparanga o runga polypropylene. Ka pania te paninga Womic i roto i te awheawhe e whakahaeretia ana te āhuarangi. Ka inehia te kaha o te kiri i te 95°C i te 75 N/cm (iti rawa 50 N/cm). Ka wetewetehia te hononga katote i te 95°C i muri i ngā rā 28: ≤ 6mm te radius.

● Ngā ratonga kawe waka ki te taha tawhiti o Te Tai Hauāuru o Ahitereiria -I tukuna ngā paipa mai i Shanghai ki te tauranga o Dampier (Te Tai Hauāuru o Ahitereiria) mā te kaipuke pakaru-rahi (haerenga 28-rā). Nā te wā o te awhiowhio, e rua ngā uta i whakaroahia. I whakarerekētia e Womic te kaupapa whakaputa hei whakakotahi i ngā uta me te karo i te hekenga o te kaipuke. I tukuna katoatia ngā 15,100 tana i roto i te matapihi kaupapa.

● Hua:I tīmata te mahi o te paipa hau kawa i te hauwhā tuatahi o te tau 2025. Whai muri i te 18 marama o te whakahaere, kāore i kitea he hapa e pā ana ki te HIC, ki te SSC rānei i roto i te tirotiro ā-roto (ILI). Kua whakaaetia e te kaiwhakahaere a Womic Steel hei kaiwhakarato whai mana mō ngā kaupapa whakawhānui hau kawa a meake nei i te Raki-uru o te Wāhi.
