Ngā Pātai Auau:
P: He aha i whiriwhiria ai a X70 i te X65 mō te paipa hau tawhiti?
A: Ka tukuna e X70 he kaha whakaputa 8% teitei ake (485 vs 450 MPa), ka taea te whakaiti i te matotoru o te pakitara tata ki te 10-12% mō te pēhanga ōrite. Mō te paipa 1,000 km, ka taea e tēnei te penapena i te 50,000-80,000 tana o te maitai, ka whakaiti nui i te utu rauemi me te tapuwae waro. Heoi, me whakamahi pereti TMCP utu nui ake a X70, he whakahaere whakarewa pakari ake, me ngā utu tirotiro teitei ake. Ko te pūwāhi pakaru he tata ki te 500-800 km. Mō ngā paipa poto ake, he ohanga ake a X65.
Q: He uaua ake te whakarewa i te X70 i te mara i te X65?
A: Ae. He nui ake te ōrite o te waro o X70 (CEV 0.38-0.43% vs X65 0.35-0.40%) ā, he tairongo ake ki te pakaru hauwai. Me whakamahana mua te whakarewanga mara (te tikanga 100-150°C mō X70 vs 75-100°C mō X65) me te whakahaere pakari i te wera whakauru me te pāmahana i waenga i ngā ara. Heoi, me ngā tikanga whakarewa whai tohu (WPS) me ngā kaiwhakarewa mohio, ka taea te whakarewa pono i te X70. Ka whakaratohia e Womic ngā taunakitanga pau mō te whakarewanga, ā, ka taea e ia te tuku tīkitipati tohu.
Q: Ka taea te whakamahi i te X70 mō te ratonga kawa (H₂S)?
A: Āe, engari me whai inenga anō: CEV ≤ 0.38% (he pai ake te ≤ 0.36%), PWHT mō ngā matotoru pakitara katoa, pakeke ≤ 85 HRB, whakamātautau HIC me te SSC. Kua tukuna e Womic te ratonga kawa X70 ki ngā kaupapa tae atu ki te 50 ppm H₂S. Kia mahara he tairongo ake a X70 ki te H₂S i te X65, X60 rānei, nō reira he maha tonu ngā kaiwhakahaere e pai ake ana ki a X65 mō ngā taiao H₂S teitei.
Q: He aha te matotoru mōrahi o te pakitara mō te paipa X70 LSAW?
A: JCOE/UOE mōrahi 50.8mm, te hononga kotahi o te pereti hurihuri tae atu ki te 70mm. Mō te matotoru o te pakitara > 40mm, ka iti haere te taputapu UOE, ā, he pai ake te pereti hurihuri. Nō nā tata nei mātou i tuku mai ai i te X70 914mm OD × 60mm WT mō te paipa CO₂ pēhanga-teitei (kaupapa CCS).
Q: He aha te whakamātautau pakari whati e hiahiatia ana mō te X70?
A: Me whakamātautau Charpy V-Notch (27J min) te API 5L engari ko te nuinga o ngā kaupapa e tohu ana i ngā uara teitei ake (hei tauira, 100J i te -20°C). E hiahiatia ana te DWTT mō te whakahaere i te horapa pakaru (te horahanga kutikuti ≥ 85% i te pāmahana whakamātautau). Mō ngā paipa taiwhenua, arctic rānei, ka tāpirihia te whakamātautau CTOD (≥ 0.25mm i te -20°C, -46°C rānei). Ka whakahaerehia e Womic ēnei whakamātautau katoa i roto i te whare, i roto rānei i ngā taiwhanga tuatoru kua whakamanahia.
Q: He aha te roanga o te wā arahi mō te paipa X70 LSAW?
A: Me roa ake ngā wā arahi mō ngā pereti TMCP mō X70 (8-12 wiki mai i te mira). Te roanga o te wā arahi: 70-100 rā mai i te ota ki te tuku FOB. Ka taea te tono tere (45-60 rā) mēnā kei roto i te taonga ngā pereti.
Q: Me whakamahi te X70 i te PWHT mō te ratonga kore-kawa?
A: Kāore te API 5L e whakahau i te PWHT mō ngā paipa X70 kei raro iho i te 50.8mm WT. Heoi, he maha ngā kaiwhakahaere e whakamahi ana i te PWHT mō ngā paipa X70 ahakoa te matotoru o te pakitara hei whakaiti i te ahotea toenga me te whakarite i te pakari o te HAZ. Ka taea e Womic te whakarato i te PWHT ina tonoa (he utu tāpiri me te wā arahi).

Ngā Whakatakotoranga:Paninga 3LPE o waho (3.0mm katoa), pito piko 30°/1.6mm, whakamātautau wai i te 19.5 MPa (pēhanga hoahoa 15.0 MPa). Pānga Charpy whakahau i te -20°C (iti rawa 80J, tutuki 150-220J) me te -46°C (iti rawa 50J, tutuki 100-160J). DWTT i te -20°C: horahanga kutikuti ≥ 85% mō te tinana paipa, ≥ 70% mō te whakarewa. UT tinana-katoa (100% o te rōrahi paipa, ehara i te tuitui anake). Tirotiro tuatoru e TÜV Rheinland puta noa i te whakaputanga. I kite a DNV i te whakamātautau wai-pūmau i te 10% o te whakaputanga.
Taupānga:Te toronga o te Paipa Hau o Āhia Waenganui-Haina (Raina D), e kawe ana i te hau māori mai i ngā mara hau i Uzbekistan mā roto i a Tajikistan ki te rohe o Haina. Ko te roa katoa o tēnei toronga: 140 km. Ka whiti te paipa i ngā pari maunga o Pamir, tae atu ki ngā rohe pakaru rū whenua e whā, ngā whitinga awa nui e toru, me te huringa teitei mai i te 400m ki te 2,800m.
Ngā Wero Hangarau me ngā Otinga:
● Teitei rawa me te rerekētanga o te pāmahana– Ko te teitei o ngā paipa kei waenganui i te 400m ki te 2,800m, me ngā pāmahana taiao mai i te -35°C i te takurua ki te +45°C i te raumati. Ko ngā paipa 48" X70 i hiahia kia pakari te pāmahana ki raro ki te -46°C (Charpy min 50J). I whiriwhiria e Womic ngā pereti TMCP me te tāpiri nikara (Ni ≤ 0.50%) hei whakatutuki i te pānga Charpy i te -46°C me te toharite 120J. DWTT i te -20°C horahanga kutikuti: 92-96% mō te tinana paipa, 82-88% mō te whakarewa. I paahitia ngā whakamātautau katoa.
● Te whakawhiti i te hapa rū whenua – te hoahoa e hangai ana ki te taumahatanga– E whā ngā wāhanga paipa e whiti ana i ngā hapa hohe me te nekehanga whenua pea tae atu ki te 1.5m. I hangaia te paipa mā te whakamahi i te hoahoa e hangai ana ki te taumahatanga (ehara i te mea e hangai ana ki te taumahatanga). Me whai paipa X70 tēnei me te ōwehenga hua kua tohua ≤ 0.85 (ka taea e te API 5L PSL2 te 0.93) me te roanga ōrite ≥ 15%. I hangaia e Womic he X70 "taumahatanga-teitei" motuhake me te ōwehenga hua 0.80-0.84 me te roanga ōrite 16-18%. I whakaratohia hoki e mātou he whakamātautau kume wāhanga-katoa (ehara i te mea ko te rīpene anake) hei manatoko i te kaha taumahatanga.
● Whenua maunga me ngā hiahia piko nui– Kei roto i te paipa he 22 kiromita o ngā paipa 48" te roa kua tāutahia ki ngā pari o te 20-30 nekehanga. He iti te piko makariri o ngā paipa X70 (ka taea e te API 5L te 1.5° mō ia 12m). I tukuna mai e Womic ngā paipa me ngā hononga roa rawa atu 18m mō ngā wāhanga tika me ngā hononga 12m mō ngā wāhanga piko. I whakahaerehia hoki e mātou he whakamātautau piko ki ngā tauira tauine katoa: i piko makariri ngā paipa 48" × 19.0mm ki te 2.0° mō ia 12m me te kore e pakaru (i manatokohia e UT me MT i muri i te piko).
● Ngā whitinga awa e hiahia ana kia matotoru te pakitara– E toru ngā whitinga awa (ngā awaawa o Oxus) i hiahiatia he 22.2mm te taumaha, kaua ki te 19.0mm hei tāpiri i te ātete ki te hinga me te piko i te wā e tāuta ana ki muri. I whakamahia e Womic te tukanga UOE mō ēnei paipa kia eke ki te āhua porowhita ≤ 0.2% (0.12-0.18%), kia maeneene ai te haere i roto i te poka. Ko ngā paipa pakitara matotoru ake i hiahiatia hoki he iti ake te wera i te wā e whakarewahia ana (≤ 2.0 kJ/mm) kia mau tonu ai te pakari o te HAZ.
● Ngā ratonga kawe tawhiti puta noa i ngā whenua e toru– I hangaia ngā paipa i te wheketere o Womic i Tianjin, i tukuna mā te tereina ki Almaty (Kazakhstan), kātahi ka whakawhitia ki ngā taraka hei tuku ki ngā wāhi hangahanga i Uzbekistan me Tajikistan. Te tawhiti katoa o te kawe: neke atu i te 5,000 km. I whakamahia e Womic ngā waka tereina motuhake me ngā tautoko whakakī me ngā whitiki maitai. I matawaihia ia paipa ki te RFID i ia wāhi whakawhiti. Kāore he paipa i pakaru i te wā o te kawe ahakoa e 3 ngā whiti rohe me te 6 ngā tukunga.
● Ngā whakaritenga paninga tino nui mō te pānga UV ki ngā teitei– I te teitei 2,800m, he 40% teitei ake te hihi UV i te taumata moana. Ka taea e te 3LPE paerewa te pirau i te UV teitei. I whakamahia e Womic te 3LPE me te paparanga o runga kua whakapūmauhia ki te UV (he 2.5% te ihirangi pango waro ki te 2.0%). I paahitia e te paninga te whakamātautau huarere UV tere (1,000 hāora QUV, te pupuri kanapa ≥ 80%). I noho te kaha kiri > 200 N/cm i muri i te pānga UV.
● Hua:I oti te toronga o te paipa 140 km te roa, ā, i whakatūria i te hauwhā tuarua o te tau 2025. I paahitia e te TÜV te tirotiro a te TÜV mō ngā tāne 75,800 katoa o ngā paipa X70 PSL2, ā, kāore he whakahē. Kua ora ngā wāhanga hoahoa e hangai ana ki te taumahatanga i ngā huihuinga ru whenua e rua (te kaha 4.2 me te 5.1) i roto i ngā marama 18 tuatahi o te mahi, ā, kāore he tohu o te piko, o te turuturu rānei. I tukuna e te kiritaki (he kamupene hau ā-motu o Uzbekistan) he mihi whaimana ki a Womic Steel mō te "mana kounga tino pai me te tautoko hangarau." Ko Womic te kaiwhakarato pai mō ngā wāhanga o te Raina D o muri mai.
