Q: ʻOi aku ka paʻakikī o ka hoʻoheheʻe ʻana iā X70 ma ke kahua ma mua o X65?
A: ʻAe. ʻOi aku ka kiʻekiʻe o ke kalapona o X70 (CEV 0.38-0.43% vs X65 0.35-0.40%) a ʻoi aku ka maʻalahi o ka haki ʻana o ka hydrogen. Pono ka hoʻomehana mua ʻana i ka wili ʻana ma ke kahua (maʻamau 100-150°C no X70 vs 75-100°C no X65) a me ka kaohi pono ʻana i ka hoʻokomo wela a me ka mahana interpass. Eia nō naʻe, me nā kaʻina hana wili kūpono (WPS) a me nā mea wili akamai, hiki ke wili pono ʻia ʻo X70. Hāʻawi ʻo Womic i nā ʻōlelo paipai no ka wili ʻana a hiki ke hāʻawi i nā kūpona hōʻoia.

Q: Hiki ke hoʻohana ʻia ʻo X70 no ka lawelawe ʻawaʻawa (H₂S)?
A: ʻAe, akā koi ʻia nā ana hou aʻe: CEV ≤ 0.38% (ʻoi aku ka maikaʻi o ≤ 0.36%), PWHT no nā mānoanoa pā āpau, paʻakikī ≤ 85 HRB, HIC a me ka hoʻāʻo ʻana o SSC. Ua hoʻolako ʻo Womic i ka lawelawe ʻawaʻawa X70 i nā papahana me ka H₂S a hiki i 50 ppm. E hoʻomaopopo he ʻoi aku ka maʻalahi o X70 i ka H₂S ma mua o X65 a i ʻole X60, no laila makemake nui nā mea hana iā X65 no nā wahi H₂S kiʻekiʻe.

Q: He aha ka mānoanoa o ka paia no ka paipu X70 LSAW?
A: JCOE/UOE max 50.8mm, ʻōwili ʻia ka pā hoʻokahi a hiki i ka 70mm. No ka mānoanoa o ka paia > 40mm, ua kaupalena ʻia ka mea hana UOE, a makemake ʻia ka pā ʻōwili. Ua hoʻolako mākou i ka X70 914mm OD × 60mm WT no kahi paipu CO₂ kiʻekiʻe-kaomi (papahana CCS).

Q: He aha ka hoʻāʻo ʻana o ka paʻakikī haki e pono ai no X70?
A: Pono ka API 5L i ka hoʻāʻo ʻana o Charpy V-Notch (27J min) akā ʻo ka hapa nui o nā papahana e kuhikuhi i nā waiwai kiʻekiʻe (e laʻa, 100J ma -20°C). Pono ʻo DWTT no ka kaohi ʻana i ka laha ʻana o ka haki (ʻāpana shear ≥ 85% ma ka mahana hoʻāʻo). No nā paipu kai a i ʻole arctic, hoʻohui pinepine ʻia ka hoʻāʻo ʻana o CTOD (≥ 0.25mm ma -20°C a i ʻole -46°C). Hana ʻo Womic i kēia mau hoʻāʻo āpau ma ka hale a i ʻole ma o nā labs ʻaoʻao ʻekolu i ʻae ʻia.

Q: He aha ka manawa alakaʻi maʻamau no ka paipu X70 LSAW?
A: Pono ʻo X70 i nā papa TMCP nona nā manawa alakaʻi lōʻihi (8-12 mau pule mai ka wili). Ka huina manawa alakaʻi: 70-100 mau lā mai ke kauoha a hiki i ka hoʻouna ʻana o FOB. Hiki ke kauoha wikiwiki (45-60 mau lā) inā loaʻa nā papa i ka waihona.

Q: Pono anei ʻo X70 i ka PWHT no ka lawelawe ʻawaʻawa ʻole?
A: ʻAʻole koi ʻo API 5L i ka PWHT no X70 ma lalo o 50.8mm WT. Eia nō naʻe, hoʻopili ka nui o nā mea hoʻohana i ka PWHT no nā paipu X70 me ka nānā ʻole i ka mānoanoa o ka paia e hōʻemi i ke koʻikoʻi koena a hōʻoia i ka paʻakikī o ka HAZ. Hiki iā Womic ke hāʻawi i ka PWHT ma ke noi (kumukūʻai hou a me ka manawa alakaʻi).

Kuhikuhi Papahana - Laina Kinoea Kūlohelohe mamao loa o ʻAsia Waena

ʻĀina:ʻO ka palena ʻo ʻUsebekistan - Tajikistan - Kina (ʻāpana o ka Paipu Kinoea ʻĀkia Waena-Kina)
Kūlana & Papa:API 5L X70 PSL2 (ʻaʻohe ʻawaʻawa, akā me nā koi haʻahaʻa haʻahaʻa)
Nā Ana a me ka Nui:

● OD 1,219mm (48″) × WT 19.0mm – 85,000 mika (ma kahi o 48,500 tons) i hana ʻia e ke kaʻina hana UOE

● OD 1,219mm (48″) × WT 22.2mm – 15,000 mika (ma kahi o 9,500 tons) i hana ʻia e ke kaʻina hana UOE (pā mānoanoa no nā keʻa mauna a me nā wahi hewa)

● OD 1,016mm (40″) × WT 17.5mm – 40,000 mika (ma kahi o 17,800 tons) i hana ʻia e ke kaʻina hana JCOE (laina lālā)
Huina:140,000 mika (140 km), ma kahi o 75,800 tone

Nā kikoʻī:ʻO ka uhi waho 3LPE (3.0mm holoʻokoʻa), nā wēlau beveled 30°/1.6mm, hydrotest ma 19.5 MPa (kaomi hoʻolālā 15.0 MPa). Ka hopena Charpy i koi ʻia ma -20°C (min 80J, i hoʻokō ʻia he 150-220J) a ma -46°C (min 50J, i hoʻokō ʻia he 100-160J). DWTT ma -20°C: ʻāpana shear ≥ 85% no ke kino paipu, ≥ 70% no ka weld. UT kino piha (100% o ka nui o ka paipu, ʻaʻole wale ka seam). Nānā ʻaoʻao ʻekolu e TÜV Rheinland ma o ka hana ʻana. Ua ʻike ʻo DNV i ka hoʻāʻo hydrostatic ma 10% o ka hana ʻana.

Noi:Ka hoʻonui ʻia ʻana o ka Paipu Kinoea ʻĀsia Waena-Kina (Laina D), e lawe ana i ke kinoea kūlohelohe mai nā kahua kinoea ma Uzbekistan ma o Tajikistan a i ka palena Kina. ʻO ka lōʻihi o kēia laina o kēia hoʻonui ʻia: 140 km. Ke hele nei ka paipu ma nā puʻu mauna ʻo Pamir, me ʻehā mau wahi hewa seismic ikaika, ʻekolu mau keʻa muliwai nui, a me kahi loli kiʻekiʻe mai 400m a i 2,800m.

Nā Pilikia ʻenehana a me nā Hoʻonā:

● ʻOkoʻa loa ke kiʻekiʻe a me ka mahana– ʻO ke kiʻekiʻe o ka paipu mai 400m a i 2,800m, me nā mahana ambient mai -35°C i ka hoʻoilo a i +45°C i ke kauwela. Pono nā paipu 48" X70 i ka paʻakikī haʻahaʻa haʻahaʻa a hiki i -46°C (Charpy min 50J). Ua koho ʻo Womic i nā papa TMCP me ka hoʻohui nickel (Ni ≤ 0.50%) e hoʻokō i ka hopena Charpy ma -46°C me ka awelika o 120J. DWTT ma -20°C shear area: 92-96% no ke kino paipu, 82-88% no ka weld. Ua hala nā hoʻāʻo āpau.

● Keʻa ʻana o ka hewa ōlaʻi - hoʻolālā e pili ana i ke kaumaha– ʻEhā mau ʻāpana paipu e hele ana ma waena o nā hewa hana me ka hiki ke neʻe i ka honua a hiki i ka 1.5m. Ua hoʻolālā ʻia ka paipu me ka hoʻolālā e pili ana i ke kaumaha (ʻaʻole i hoʻokumu ʻia i ke kaumaha). Pono kēia i nā paipu X70 me kahi lakio hua i kuhikuhi ʻia ≤ 0.85 (ʻae ʻo API 5L PSL2 i 0.93) a me ka elongation like ≥ 15%. Ua hana ʻo Womic i kahi "high-strain" X70 kūikawā me ka lakio hua 0.80-0.84 a me ka elongation like 16-18%. Ua hāʻawi pū mākou i ka hoʻāʻo tensile ʻāpana piha (ʻaʻole wale ka strip) e hōʻoia i ka hiki ke kaumaha.

● ʻĀina mauna me nā koi kūlou koʻikoʻi– Aia i loko o ka paipu he 22 km o ka paipu 48" i hoʻokomo ʻia ma nā pali o 20-30 degere. Ua kaupalena ʻia ke kūlou anu o nā paipu X70 (ʻae ʻo API 5L i ka 1.5° no 12m). Ua hoʻolako ʻo Womic i nā paipu me nā hui 18m lōʻihi loa no nā ʻāpana pololei a me nā hui 12m no nā ʻāpana kūlou. Ua hana pū mākou i ka hoʻāʻo kūlou ma nā laʻana piha: ua kūlou anu ʻia nā paipu 48" × 19.0mm i 2.0° no 12m me ka ʻole o ka haki ʻana (i hōʻoia ʻia e UT a me MT ma hope o ke kūlou ʻana).

● Nā keʻa muliwai e koi ana i ka mānoanoa o ka pā– ʻEkolu mau keʻa muliwai (nā kahawai ʻo Oxus) e pono ai he 22.2mm WT ma kahi o 19.0mm no ka hiolo hou a me ke kū'ē kūlou i ka wā o ke kau ʻana i ka pullback. Ua hoʻohana ʻo Womic i ke kaʻina hana UOE no kēia mau paipu e hoʻokō i ka ovality ≤ 0.2% (maoli 0.12-0.18%), e hōʻoiaʻiʻo ana i ka hele mālie ma o ka lua. Pono pū nā paipu paia mānoanoa i ka hoʻokomo wela haʻahaʻa i ka wā o ka wili ʻana (≤ 2.0 kJ/mm) e mālama i ka paʻakikī HAZ.

● Nā hana hoʻokele mamao loa ma nā ʻāina ʻekolu– Ua hana ʻia nā paipu ma ka hale hana ʻo Womic ma Tianjin, ua hoʻouna ʻia ma ke kaʻaahi i Almaty (Kazakhstan), a laila ua hoʻoili ʻia i nā kalaka no ka lawe ʻana i nā wahi kūkulu ma Uzbekistan a me Tajikistan. Ka mamao holoʻokoʻa o ka hele ʻana: ma luna o 5,000 km. Ua hoʻohana ʻo Womic i nā kaʻa kaʻaahi kūikawā me nā kākoʻo i hoʻopaʻa ʻia a me ke kāʻei kila. Ua scan ʻia kēlā me kēia paipu me RFID ma kēlā me kēia wahi hoʻoili. ʻAʻohe paipu i hōʻino ʻia i ka wā o ka hele ʻana me ka nānā ʻole i 3 mau keʻa palena a me 6 mau hoʻouna ʻana.

● Nā koi uhi koʻikoʻi no ka hōʻike UV kiʻekiʻe– Ma ke kiʻekiʻe o 2,800m, ʻoi aku ka kiʻekiʻe o ka radiation UV ma mua o 40% ma mua o ka ʻilikai. Hiki i ka 3LPE maʻamau ke hōʻino i ka UV kiʻekiʻe. Ua hoʻopili ʻo Womic i ka 3LPE me ka papa luna i hoʻoikaika ʻia e ka UV (ʻike ʻeleʻele kalapona 2.5% vs maʻamau 2.0%). Ua hala ka uhi ʻana i ka hoʻāʻo wikiwiki ʻana i ka wā UV (1,000 hola QUV, paʻa ʻana o ka ʻōlinolino ≥ 80%). Ua noho ka ikaika o ka ʻili ma mua o 200 N/cm ma hope o ka hōʻike ʻana iā UV.

● Hopena:Ua hoʻopau ʻia a ua hoʻomaka ʻia ka hoʻonui ʻana o ka paipu 140 km i ka hapaha ʻelua o 2025. Ua hala nā tone 75,800 a pau o nā paipu X70 PSL2 i ka nānā ʻana o TÜV me ka ʻole o nā hōʻole. Ua ola nā ʻāpana hoʻolālā e pili ana i ke kaumaha i ʻelua mau hanana seismic (magnitude 4.2 a me 5.1) i nā mahina 18 mua o ka hana me ka ʻole o nā hōʻailona o ka buckling a i ʻole ka leakage. Ua hoʻopuka ka mea kūʻai aku (kahi hui kinoea aupuni o Uzbekistan) i kahi hoʻomaikaʻi kūhelu iā Womic Steel no ka "mana maikaʻi loa a me ke kākoʻo loea." ʻO Womic i kēia manawa ka mea hoʻolako makemake ʻia no nā ʻāpana e hiki mai ana o ka Line D.
