Tohutoro Kaupapa – Whatunga Kohikohi Hauāuru o Āwherika ki te Hauāuru
Whenua:Ngāiria (rohe o te Niger Delta)
Paerewa me te Taumata:API 5L X42 PSL2 (ratonga kawa, kua whakamatautauria te HIC)
Ngā Ahu me te Rahinga:
OD 508mm (20″) × T 11.9mm – 12,000 mita (tata ki te 1,800 tāne) i hangaia mā te tukanga JCOE
OD 762mm (30″) × WT 19.0mm – 3,500 mita (tata ki te 1,550 tāne) i hangaia mā te pereti hurihuri kotahi te hononga me te PWHT
Ngā Whakatakotoranga:Paninga 3LPE o waho (matotoru katoa 2.8mm), pito piko 30° / 1.6mm te mata pakiaka, whakamātautau wai i te 8.5 MPa (pēhanga hoahoa 6.4 MPa). Pānga Charpy me whakahau i te 0°C (iti rawa 27J, tutuki 65–90J). HIC mō ia NACE TM0284 Otinga A, 96h – paearu whakaae: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%.
Taupānga:I kohia te hau māori mai i ngā puna e ono ki tētahi whare tukatuka matua i te whenua reporepo o te Niger Delta. I whakamahia te paipa pakitara taumaha 30 inihi mō te pane matua e whiti ana i tētahi wāhanga reporepo 1.2km te roa, ā, i whakamahia ngā paipa JCOE 20 inihi hei raina peka.
Ngā Wero Hangarau me ngā Otinga:
●Te whiti i te repo me te paipa pakitara taumaha– Me tāuta ngā paipa 30″ × 19.0mm (tata ki te 355 kg/m) ki runga i tētahi repo he uku ngohengohe rawa. Kāore i taea e ngā poti tuku iho te uru atu ki te papaanga. I whakaratohia e Womic Steel ngā paipa he hononga kotahi tino roa (18m hei utu mō te 12m paerewa) hei whakaiti i te maha o ngā whakapiringa porowhita mā te 33%, me te whakaiti i te whakapiringa i runga i te papaanga i ngā āhuatanga uaua. I whakaratohia hoki e mātou ngā taunakitanga taipitopito mō te hiki me te whakahaere tae atu ki te mokowā o ngā kurupae horapa.
●Te tutuki i ngā whakaritenga ratonga kino (kei te wātea te H₂S)– I roto i te hau e pā ana, tae atu ki te 30 ppm te H₂S. I whakahaerehia e Womic te whakamātautau HIC i runga i ngā paipa JCOE 20″ me ngā paipa pereti hurihuri 30″. I paahitia ngā tauira katoa me te CLR 0%, CTR 0%, CSR 0%. Mō te paipa 30″ (19mm WT), i hiahiatia e te kiritaki he pakeke i raro i te 85 HRB (he kaha ake i te 90 HRB a te API 5L). I whakamahia e Womic te whakamahana ā-rohe ki te hononga whakarewa hei whakarite i te pakeke ōrite. Ngā Hua: konganuku turanga 78–82 HRB, whakarewa 80–85 HRB.
● Te piri o te paninga 3LPE i te makuku nui– Nā te whakaurunga o te repo i rumakina ai ngā paipa ki roto i te wai mō ngā wiki i mua i te whakakī anō. Ka taea e te paerewa 3LPE te wetewete cathodic mēnā kāore te haumākū o te tono e whakahaeretia. I whakamahia e Womic te paninga i roto i tētahi awheawhe e whakahaeretia ana te āhuarangi (mōrahi 60% RH) ā, i mahia he kitenga hararei 100% i te 5kV. Ko te kaha kiri i whakamatautauria i te 25°C i homai he > 200 N/cm, he nui ake i te whakaritenga ISO 21809 o te 100 N/cm.
●Ngā mahi kawe waka ki te wāhi tawhiti– I tukuna ngā paipa mai i Shanghai ki te Tōhanga o Tin Can Island, Lagos, kātahi ka haria ki te taraka mō te 380km ki te wāhi o te Niger Delta. He kino ngā āhuatanga o te rori, ā, he iti noa ngā here taumaha. I hangaia e Womic tētahi mahere tuku kaipuke mā te whakamahi i ngā roa paerewa 12m mō ngā paipa 20″ (he paihere) me ngā hononga takitahi 18m mō ngā paipa 30″ i runga i ngā wakatō papatahi me ngā waka tautoko. Kāore i pakaru te paninga, i piko rānei i te wā e kawe ana.
● Hua:I whakatūria te whatunga kohikohi hau i te hauwhā tuatahi o te tau 2024. I paahitia e SGS Nigeria ngā paipa 1,550 tana katoa, he 30″ te whānui, me ngā paipa 20″ he 1,800 tana. Kāore he hapa whakarewa i te wā o te whakarewa porowhita o te mara, nā te āhua o te piko me te mana porowhita tonu (≤ 0.3% mō ngā paipa JCOE, ≤ 0.5% mō ngā paipa pereti hurihuri). Kua rārangihia a Womic Steel hei kaiwhakarato kua whakaaetia mō ngā whakawhānuitanga paipa a meake nei a te kiritaki.
