1. Womic Steel: Nā Mana Hana a me ka Ikaika o ka ʻOihana

Hoʻokele ʻo Womic Steel Group i nā laina hana LSAW he nui e uhi ana i ʻekolu mau ʻano hana mua e hoʻokō ai i nā koi papahana like ʻole:

● Laina JCOE:No nā anawaena 406mm - 1,422mm (16″–56″), ʻo ka mānoanoa o ka paia a hiki i 50.8mm. Hoʻokumu ʻana o JCO ʻanuʻu me ka hoʻonui ʻana o ka mīkini. Hana pono kiʻekiʻe, poepoe maikaʻi.

●Laina UOE:No nā anawaena 508mm - 1,220mm (20″–48″), ʻo ka mānoanoa o ka paia a hiki i ka 40mm. Hoʻokumu ʻia ka U a laila hoʻokumu ʻia ka O me ka hoʻonui hydraulic. ʻO ka pololei o ke ana ʻana maikaʻi loa, makemake ʻia no ka lawelawe wai hohonu a me ka ʻawaʻawa.

●Papa ʻōwili (Hui Hoʻokahi):No nā anawaena 600mm - 1,600mm (24″–63″), ʻo ka mānoanoa o ka paia mai 25mm a hiki i ka 60mm. Hoʻokahi papa i ʻōwili ʻia i loko o kahi cylinder me hoʻokahi weld longitudinal. Kūpono no ka mānoanoa o ka paia kaumaha ma mua o ka hiki o JCOE/UOE.

●Papa ʻōwili (Hui pālua):No ka mānoanoa o ka paia > 50.8mm a hiki i 80mm, e hoʻohana ana i ʻelua mau papa i hoʻopaʻa ʻia ma ke ʻano lōʻihi. Hoʻohana pinepine ʻia no nā paipu manifold kahua ʻaila kiʻekiʻe.

ʻOi aku ka nui o ka mana LSAW ma mua o 300,000 tons i kēlā me kēia makahiki. Loaʻa iā Womic Steel ka API 5L Monogram, ISO 9001, CE PED, a ua nānā mau ʻia e ABS, DNV, TÜV, a me BV. He moʻolelo kaulana honua ma 80+ mau ʻāina.

Ka Hoʻololi Hana:

●JCOE: 406–1,422mm OD × 6.0–50.8mm WT × ≤ 18m

●UOE: 508–1,220mm OD × 6.0–40.0mm WT × ≤ 24m (hoʻomaikaʻi ka hoʻonui ʻana o ka mīkini i ka poepoe)

●Papa ʻōwili (humuhumu hoʻokahi): 600–1,600mm OD × 25–60mm WT × ≤ 12m (palena kaumaha)

●Papa ʻōwili (humuhumu pālua): 1,000–2,000mm OD × 25–80mm WT × ≤ 12m

OD 508mm (20″) × WT 11.9mm – 12,000 mika (ma kahi o 1,800 tons) i hana ʻia e ke kaʻina hana JCOE

OD 762mm (30″) × WT 19.0mm - 3,500 mika (approx. 1,550 tons) i hana ʻia e ka ʻōwili ʻia o ka pā hoʻokahi me ka PWHT
Nā kikoʻī:ʻO ka uhi waho 3LPE (mānoanoa holoʻokoʻa 2.8mm), nā wēlau beveled 30° / 1.6mm ke alo aʻa, hydrotest ma 8.5 MPa (kaomi hoʻolālā 6.4 MPa). Ka hopena Charpy i koi ʻia ma 0°C (min 27J, i hoʻokō ʻia he 65–90J). HIC no NACE TM0284 Solution A, 96h - nā pae ʻae: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%.
Noi:ʻO ka hōʻiliʻili ʻana i ke kinoea kūlohelohe mai nā poʻo luawai ʻeono i kahi hale hana kikowaena ma ka ʻāina pulu o Niger Delta. Ua hoʻohana ʻia ka paipu paia kaumaha 30″ no ke poʻo nui e hele ana ma kahi ʻāpana pulu 1.2km, ʻoiai ʻo nā paipu JCOE 20″ i lawelawe ma ke ʻano he mau laina lālā.

Nā Pilikia ʻenehana a me nā Hoʻonā:

●Ke ala ʻana o ka ʻāina pāpū me ka paipu paia kaumaha– Pono e hoʻokomo ʻia nā paipu 30″ × 19.0mm (ma kahi o 355 kg/m) ma luna o kahi ʻūpā me ka lepo palupalu loa. ʻAʻole hiki i nā waʻa hoʻomoe maʻamau ke komo i ke kahua. Ua hoʻolako ʻo Womic Steel i nā paipu me nā hui hoʻokahi lōʻihi loa (18m ma kahi o 12m maʻamau) e hōʻemi i ka helu o nā wili girth kahua ma 33%, e hoʻemi ana i ka wili ʻana ma ke kahua i nā kūlana paʻakikī. Ua hāʻawi pū mākou i nā ʻōlelo aʻoaʻo kikoʻī no ka hāpai ʻana a me ka lawelawe ʻana me ka hoʻokaʻawale ʻana i nā kaola spreader.

●Hoʻokō lawelawe ʻawaʻawa (H₂S i kēia manawa)– Aia i loko o ke kinoea pili a hiki i ka 30 ppm H₂S. Ua hana ʻo Womic i ka hoʻāʻo HIC ma nā paipu papa ʻōwili 20″ JCOE a me 30″. Ua hala nā laʻana āpau me CLR 0%, CTR 0%, CSR 0%. No ka paipu 30″ (19mm WT), koi ka mea kūʻai aku i ka paʻakikī ma lalo o 85 HRB (ʻoi aku ka paʻakikī ma mua o ka API 5L's 90 HRB). Ua hoʻopili ʻo Womic i ka hoʻomehana induction kūloko i ka humuhumu weld e hōʻoia i ka paʻakikī like. Nā hopena: metala kumu 78–82 HRB, weld 80–85 HRB.

● Hoʻopili ʻia ka uhi ʻana o 3LPE i ka haʻahaʻa kiʻekiʻe– ʻO ke kau ʻana o ka ʻōpala i manaʻo ʻia e hoʻokomo ʻia nā paipu i loko o ka wai no nā pule ma mua o ka hoʻopiha hou ʻana. Hiki i ka 3LPE maʻamau ke ʻike i ka cathodic disbondment inā ʻaʻole i kāohi ʻia ka makū o ka noi. Ua hoʻopili ʻo Womic i ka uhi ʻana i loko o kahi hale hana i kāohi ʻia e ke aniau (max 60% RH) a ua hana i ka ʻike hoʻomaha 100% ma 5kV. ʻO ka ikaika peel i hoʻāʻo ʻia ma 25°C i hāʻawi i ka > 200 N/cm, ʻoi aku ma mua o ke koi ISO 21809 o 100 N/cm.

●Logistics i kahi mamao– Ua hoʻouna ʻia nā paipu mai Shanghai a i Tin Can Island Port, Lagos, a laila ua lawe ʻia ma ke kalaka he 380km i kahi o Niger Delta. ʻAʻole maikaʻi nā kūlana alanui me nā palena kaumaha. Ua hoʻolālā ʻo Womic i kahi hoʻolālā hoʻouna me ka hoʻohana ʻana i nā lōʻihi maʻamau 12m no nā paipu 20″ (i hoʻopili ʻia) a me 18m mau hui hoʻokahi no nā paipu 30″ ma nā trailer flatbed me nā kaʻa ukali. ʻAʻohe pōʻino o ka uhi a i ʻole ke kūlou ʻana i ka wā o ka lawe ʻana.

● Hopena:Ua hoʻomaka ʻia ka pūnaewele hōʻiliʻili kinoea i ka hapaha mua o 2024. Ua hala nā paipu 1,550 tons a pau o 30″ a me 1,800 tons o 20″ i ka nānā ʻana o ka ʻaoʻao ʻekolu e SGS Nigeria. Ua hōʻike ka mea kūʻai aku ʻaʻohe hemahema weld i ka wā o ka welding girth kahua, i hoʻopili ʻia i ke ʻano bevel kūlike a me ka kaohi ovality (≤ 0.3% no nā paipu JCOE, ≤ 0.5% no nā paipu pā i ʻōwili ʻia). Ua helu ʻia ʻo Womic Steel i kēia manawa ma ke ʻano he mea hoʻolako i ʻae ʻia no ka hoʻonui ʻana o ka pipeline o ka mea kūʻai aku i ka wā e hiki mai ana.
