Kuhikuhi Papahana - ʻAla Hoʻokuʻu ʻAila Maka o ʻApelika Hikina

ʻĀina:ʻUganda / Tanzania (Paipa ʻAila Maka o ʻApelika Hikina - EACOP)
Kūlana & Papa:API 5L X52 PSL2 (lawelawe ʻawaʻawa, me ka hoʻāʻo ʻana o HIC a me SSC)
Nā Ana a me ka Nui:

● OD 610mm (24″) × WT 12.7mm – 48,000 mika (ma kahi o 7,200 tons) i hana ʻia e ke kaʻina hana UOE

● OD 610mm (24″) × WT 15.9mm – 12,000 mika (ma kahi o 2,400 tons) i hana ʻia e ke kaʻina hana UOE (pā mānoanoa no ke keʻa ʻana o ka muliwai)

● OD 914mm (36″) × WT 19.0mm – 8,500 mika (ma kahi o 3,400 tons) i hana ʻia e ke kaʻina hana JCOE no nā laina bypass kikowaena pamu
Huina:68,500 mika (68.5 km), ma kahi o 13,000 tone

Nā kikoʻī:ʻO ka uhi waho 3LPE (3.0mm ka mānoanoa holoʻokoʻa) e like me ISO 21809, nā wēlau beveled 30° / 1.6mm ke alo o ke aʻa, hydrotest ma 11.5 MPa (kaomi hoʻolālā 8.5 MPa). Ka hopena Charpy i koi ʻia ma 0°C (min 27J, i hoʻokō ʻia he 85-120J). HIC no NACE TM0284 Solution A, 96h - ʻae ʻia: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. SSC no NACE TM0177 ʻAno A, 720h - ʻaʻole ʻae ʻia ka haki ʻana. Hoʻopili ʻia ʻo PWHT no nā paipu āpau me WT ≥ 15.9mm.

Noi:Paipu hoʻokuʻu aku i ka ʻaila maka mai Uganda i hoʻopaʻa ʻia i ka ʻāina (ʻāina ʻo Hoima) a i ke awa ʻo Tanga o Tanzania ma ke Kai ʻInikia. ʻO ka lōʻihi o ka paipu he 1,443 km. Ua hoʻolako ʻo Womic Steel i 68.5 km o ka huina, me nā ʻāpana ma waena o nā wahi holoholona hihiu koʻikoʻi a me nā wahi e hele ai nā muliwai nui.

Nā Pilikia ʻenehana a me nā Hoʻonā:

● Ka hoʻokō ʻana i ka lawelawe ʻawaʻawa no ka ʻaila maka me H₂S– Aia ka ʻaila maka Ugandan i ka H₂S i hoʻoheheʻe ʻia a hiki i ka 15 ppm me ka nui o ka wai. Pono ka hoʻāʻo HIC a me SSC koʻikoʻi. Ua hana ʻo Womic i ka hoʻāʻo hōʻoia ma 15 mau ʻāpana hana. Ua hala nā mea āpau me CLR 0%, CTR 0%, CSR 0% no HIC. ʻAʻole i hōʻike ka hoʻāʻo SSC (NACE TM0177, 720h) i ka haki ʻana o ka ʻili. Ua hoʻokō mākou i kēia ma ka mālama ʻana iā CEV ≤ 0.38% (ma lalo loa o ka palena PSL2 o 0.43%) a me ka hoʻopili ʻana iā PWHT no nā paipu āpau ma luna o 12.7mm WT, ʻoiai ʻaʻole koi ʻo API 5L i ka PWHT ma lalo o 25.4mm. Ua ʻike maka ka mea nānā o ka mea kūʻai aku (SGS) i nā hoʻāʻo āpau.

● Nā palena o ke kaiapuni o nā wahi holoholona hihiu– Hele ka paipu ma waena o ʻelua mau wahi mālama holoholona hihiu aupuni. He paʻakikī ke hoʻoponopono i ka pohō o ka uhi i ka wā o ke kau ʻana ma muli o ke komo ʻana i kaupalena ʻia. Ua hoʻopili ʻo Womic i kahi papa mōhai o ka polyethylene (0.5mm keu ma luna o ka 3LPE maʻamau) ma ke ʻano he uhi pale abrasion. Ua hana pū mākou i ka ʻike hoʻomaha 100% ma 7kV (ʻo ke kūlana he 5kV) e hōʻoia i ka ʻole o nā hoʻomaha uhi. Ua hoʻāʻo ʻia ka ikaika ʻili ma 250 N/cm ma 25°C, 150 N/cm ma 70°C.

● Nā keʻa muliwai e pono ai ka pā mānoanoa– ʻElima mau keʻa muliwai nui (nā kahawai o ka Nile) e pono ai ka WT 15.9mm ma kahi o 12.7mm no ke kū'ē hou aku i ka hiolo a me ka ʻae kūlou i ka wā o ke kau ʻana i ka sagbend. No kēia mau paipu paia mānoanoa, ua hoʻohana mākou i ke kaʻina hana UOE no ka poepoe maikaʻi aʻe (± 0.2% OD) e hōʻoia i ka hoʻopili pono ʻana o ke kahua ma nā ʻāpana keʻa. Ua ana ʻia ka ovality ma 0.15-0.18%, ma lalo loa o ka palena 0.5%.

● Nā hana hoʻokele ma ka ʻāina no ka mamao loa– Ua hoʻouna ʻia nā paipu mai Shanghai a i ke awa ʻo Dar es Salaam (Tanzania), a laila ua lawe ʻia i 1,200 km i ka laha ʻana o ka paipu ʻo Uganda. ʻO nā kūlana alanui ma ke komohana o Tanzania e komo pū ana me nā ʻāpana i hoʻopaʻa ʻole ʻia. Ua hoʻolālā ʻo Womic i kahi hoʻolālā hoʻouna kūikawā: 12m ka lōʻihi wale nō (ʻaʻohe hui 18m no ka ʻāpana Uganda) e kūpono i nā kalaka pālahalaha maʻamau. Ua hoʻopaʻa ʻia kēlā me kēia paipu me nā kaula padded. Ua hāʻawi mākou i nā kiʻikuhi hoʻouka a me ke aʻo ʻana i ka hui kalaka kūloko. ʻAʻohe paipu i hōʻino ʻia i ka wā o ka hele ʻana ma uka he 1,200 km.

● Nā palapala koʻikoʻi a me ka hiki ke hahai ʻia– Ua koi ka papahana i nā palapala hōʻoia EN 10204 Type 3.2 no kēlā me kēia helu wela, me ka hiki ke hahai piha ʻia mai ka pā a i ka paipu i hoʻopau ʻia. Ua hoʻonoho ʻo Womic i kahi mea hoʻokele palapala i hoʻolaʻa ʻia nāna i hahai i nā paipu 68.5 km āpau. Ua sila ʻia kēlā me kēia paipu me ka helu wela, ka helu paipu, a me nā hoʻonohonoho GPS o ka hana ʻana. Ua nānā ka hui QA o ka mea kūʻai aku i kā mākou hale hana i ʻelua manawa i ka wā o ka hana ʻana; ua hala nā loiloi ʻelua me ka ʻole o nā kūlike ʻole.

Hopena:Ua hoʻolālā ʻia ka hoʻopau ʻana o ka East African Crude Oil Pipeline (EACOP) i ka hapaha 2 o 2025. Ua hāʻawi ʻia nā paipu X52 PSL2 he 13,000 tons a Womic Steel ma luna o 8 mau mahina (ka hoʻouna mua ʻana ʻOkakopa 2023, ka hoʻouna hope loa ʻana o Mei 2024). Ua hala nā paipu a pau i ka nānā ʻana o ka ʻaoʻao ʻekolu e SGS Tanzania. Ua hoʻopuka ka mea kūʻai aku (he hui o nā ʻoihana ʻaila honua) i kahi leka hoʻomaikaʻi no ka kaohi maikaʻi o Womic a me ka hāʻawi ʻana i ka manawa kūpono. I kēia manawa, he mea hoʻolako i hōʻoia mua ʻia ʻo Womic no ka hoʻonui ʻana i nā paipu e hiki mai ana ma ka ʻāina.
