● Qhov ntev txog li 24m txo qhov sib txuas ntawm thaj teb los ntawm 30-40% (feem ntau yog 12m vs 18m vs 24m)
● Kev taug qab tag nrho los ntawm tus lej cua sov phaj mus rau cov yeeb nkab tiav (tus lej cua sov raug muab luam tawm rau ntawm txhua lub yeeb nkab)
● Tshaj 3,000 km ntawm cov kav dej X52 tau muab thoob ntiaj teb nrog xoom qhov tsis ua haujlwm hauv kev pabcuam
Cov Lus Nug Feem Ntau:
Q: Qhov txawv tseem ceeb ntawm X52 PSL1 thiab PSL2 rau LSAW yeeb nkab yog dab tsi?
A: PSL2 muaj cov kev txwv tshuaj lom neeg nruj dua (qis dua C, P, S), yuav tsum muaj Charpy impact toughness (27J yam tsawg kawg nkaus @ 0 ° C lossis qis dua), qhov siab tshaj plaws hardness txwv (90 HRB), thiab xav tau NDT nruj dua (100% UT piv rau qhov chaw UT rau PSL1). Rau cov kav dej roj siab, offshore, lossis kev pabcuam qaub, PSL2 yog qhov yuav tsum muaj. Rau cov kav dej lossis roj qis, PSL1 yog qhov txais tau thiab pheej yig dua.
Q: Koj puas tuaj yeem muab X52 nrog kev sim qhov kub qis rau cov haujlwm arctic?
A: Yog. Peb muab X52 PSL2 nrog Charpy impact testing ntawm -46 ° C (min 27J) thiab DWTT ntawm -20 ° C (min 85% shear area). Peb tau muab arctic grade X52 rau Canadian thiab Lavxias teb sab projects. Thov qhia qhov kub thiab txias thiab lub zog uas xav tau thaum nug.
Q: Qhov siab tshaj plaws ntawm phab ntsa uas koj tuaj yeem tsim tau rau X52 LSAW yog dab tsi?
A: JCOE txheej txheem siab tshaj 50.8 hli, UOE txheej txheem siab tshaj 40 hli, dov phaj ib leeg txog li 70 hli, dov phaj ob leeg txog li 80 hli. Rau phab ntsa tuab tshaj 50.8 hli, PWHT yog qhov yuav tsum tau ua. Tsis ntev los no peb tau muab X52 1,600 hli OD × 70 hli WT rau qhov project txhaj dej siab hauv Oman.
Q: Koj tswj qhov nyuaj rau X52 kev pabcuam qaub li cas?
A: Peb tswj cov tshuaj lom neeg sib xyaw (CEV ≤ 0.40% rau kev pabcuam qaub, qis dua tus qauv 0.43%), tswj cov cua sov nkag thaum lub sijhawm SAW vuam (≤ 3.0 kJ / hli), thiab siv PWHT rau phab ntsa tuab ≥ 20mm. Qhov nyuaj tom qab PWHT feem ntau yog 78-85 HRB rau cov hlau puag thiab 82-88 HRB rau vuam. Peb muab cov ntaub ntawv qhia txog qhov nyuaj tag nrho.
Q: Koj puas muab kev tshuaj xyuas sab nraud rau cov kav dej X52 LSAW?
A: Yog. Peb ua haujlwm nrog SGS, BV, TÜV, DNV, ABS, thiab LR. Kev tshuaj xyuas tuaj yeem ua tiav ntawm peb lub Hoobkas thaum lub sijhawm tsim khoom, ua tim khawv los ntawm tus neeg sawv cev ntawm tus neeg siv khoom lossis lub koom haum thib peb. Peb muab daim ntawv pov thawj EN 10204 Hom 3.2 thaum thov.
Q: Lub sijhawm ua cov yeeb nkab X52 LSAW feem ntau yog dab tsi?
A: Lub sijhawm ua tus qauv: 30-45 hnub rau PSL1, 45-60 hnub rau PSL2 nrog kev sim kev pabcuam qaub. Kev txiav txim maj (20-30 hnub) ua tau rau cov khoom me me (<500 tons). Rau cov kev txiav txim loj heev (>10,000 tons), lub sijhawm ua tus qauv yuav ntev txog 75 hnub nyob ntawm seb muaj phaj.
Q: Koj puas tuaj yeem muab X52 nrog 3LPE txheej thiab cov txheej txheem hnyav rau cov kav dej hiav txwv?
A: Yog. Peb muab 3LPE txheej raws li ISO 21809 (2.5-3.5mm tag nrho tuab) thiab tuaj yeem sib koom ua ke qhov hnyav txheej (40-120mm tuab, qhov ceev 2,400-3,050 kg / m³) ntawm peb tus khub txheej txheej hauv Tianjin. Peb tau muab cov txheej txheem X52 tawm hauv hiav txwv rau Nyab Laj, Indonesia, thiab Middle East cov haujlwm.
Cov Lus Qhia Txog Qhov Project - East Africa Crude Oil Export Pipeline
Lub Tebchaws:Uganda / Tanzania (Cov kav dej roj av sab hnub tuaj ntawm teb chaws Africa - EACOP)
Tus Qauv & Qib:API 5L X52 PSL2 (kev pabcuam qaub, nrog rau kev kuaj HIC thiab SSC)
Qhov Loj & Qhov Ntau:
● OD 610mm (24″) × WT 12.7mm – 48,000 meters (kwv yees li 7,200 tons) tsim los ntawm UOE txheej txheem
● OD 610mm (24″) × WT 15.9mm – 12,000 meters (kwv yees li 2,400 tons) tsim los ntawm UOE txheej txheem (phab ntsa tuab dua rau kev hla dej)
● OD 914mm (36″) × WT 19.0mm – 8,500 meters (kwv yees li 3,400 tons) tsim los ntawm JCOE txheej txheem rau cov kab bypass chaw nres tsheb twj tso kua mis
Tag Nrho:68,500 meters (68.5 km), kwv yees li 13,000 tons
Cov Lus Qhia:Txheej 3LPE sab nraud (3.0 hli tag nrho tuab) raws li ISO 21809, qhov kawg beveled 30 ° / 1.6 hli hauv paus ntsej muag, hydrotest ntawm 11.5 MPa (tsim siab 8.5 MPa). Yuav tsum muaj Charpy cuam tshuam ntawm 0 ° C (yam tsawg kawg nkaus 27J, ua tiav 85-120J). HIC raws li NACE TM0284 Tshuaj A, 96h - kev lees txais: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. SSC raws li NACE TM0177 Txoj Kev A, 720h - tsis pub tawg. PWHT thov rau txhua lub kav dej nrog WT ≥ 15.9 hli.
Daim Ntawv Thov:Cov kav dej xa roj av los ntawm thaj av Uganda (thaj tsam Hoima) mus rau Tanzania lub chaw nres nkoj Tanga ntawm Dej Hiav Txwv Indian. Tag nrho cov kav dej ntev yog 1,443 km. Womic Steel tau muab 68.5 km ntawm tag nrho, suav nrog cov ntu hla cov chaw tsiaj qus thiab cov dej hla loj.
Cov Kev Sib Tw thiab Kev Dais Teeb Meem:
● Kev ua raws li kev pabcuam qaub rau cov roj nyoos uas muaj H₂S– Cov roj av Ugandan muaj H₂S yaj txog li 15 ppm nrog cov dej hauv. Yuav tsum tau kuaj HIC thiab SSC nruj heev. Womic tau ua qhov kev kuaj xyuas kev tsim nyog ntawm 15 qhov chaw tsim khoom. Txhua qhov dhau nrog CLR 0%, CTR 0%, CSR 0% rau HIC. Kev kuaj SSC (NACE TM0177, 720h) tsis pom qhov tawg ntawm qhov chaw. Peb ua tiav qhov no los ntawm kev khaws CEV ≤ 0.38% (qis dua PSL2 txwv ntawm 0.43%) thiab siv PWHT rau txhua lub kav dej saum 12.7 hli WT, txawm tias API 5L tsis yuam kom PWHT qis dua 25.4 hli. Tus neeg soj ntsuam ntawm tus neeg siv khoom (SGS) tau pom txhua qhov kev kuaj xyuas.
● Cov kev txwv ib puag ncig ntawm thaj chaw tsiaj qus– Cov kav dej hla dhau ob lub teb chaws cov tsiaj qus reserves. Kev puas tsuaj ntawm txheej thaum lub sijhawm teeb tsa yuav nyuaj rau kho vim muaj kev txwv tsis pub nkag. Womic tau siv ib txheej polyethylene (ntxiv 0.5 hli rau saum tus qauv 3LPE) ua ib txheej tiv taus kev txhuam. Peb kuj tau ua 100% kev kuaj pom hnub so ntawm 7kV (tus qauv yog 5kV) kom ntseeg tau tias tsis muaj txheej hnub so. Kev kuaj lub zog tev ntawm 250 N / cm ntawm 25 ° C, 150 N / cm ntawm 70 ° C.
● Kev hla dej xav tau phab ntsa tuab dua– Tsib qhov chaw hla dej loj (Nile tributaries) xav tau WT 15.9mm es tsis yog 12.7mm rau kev tiv thaiv kev tawg ntxiv thiab kev tso cai khoov thaum lub sijhawm sagbend installation. Rau cov kav dej phab ntsa tuab dua no, peb siv cov txheej txheem UOE rau qhov sib npaug zoo dua (± 0.2% OD) kom ntseeg tau tias qhov vuam girth txhim khu kev qha hauv cov ntu hla. Ovality tau ntsuas ntawm 0.15-0.18%, qis dua 0.5% txwv.
● Kev thauj mus los deb ntawm thaj av– Cov kav dej tau raug xa los ntawm Shanghai mus rau chaw nres nkoj Dar es Salaam (Tanzania), tom qab ntawd thauj khoom mus txog 1,200 km mus rau qhov chaw xa dej ntawm Uganda. Cov xwm txheej ntawm txoj kev hauv sab hnub poob Tanzania suav nrog cov ntu tsis tau paved. Womic tsim ib txoj kev npaj xa khoom tshwj xeeb: tsuas yog 12m ntev xwb (tsis muaj 18m sib txuas rau ntu Uganda) kom haum rau cov tsheb thauj khoom tiaj tus. Txhua lub kav dej tau khi ua ke nrog cov hlua khi. Peb tau muab cov duab kos thiab kev cob qhia rau lub tuam txhab thauj khoom hauv zos. Tsis muaj cov kav dej puas tsuaj thaum lub sijhawm hla tebchaws 1,200 km.
● Cov ntaub ntawv sau tseg thiab kev taug qab uas nruj heev– Qhov project xav tau daim ntawv pov thawj EN 10204 Hom 3.2 rau txhua tus lej cua sov, nrog rau kev taug qab tag nrho los ntawm lub phaj mus rau cov yeeb nkab tiav. Womic tau muab ib tus neeg tswj xyuas cov ntaub ntawv tshwj xeeb uas taug qab tag nrho 68.5 km ntawm cov yeeb nkab. Txhua lub yeeb nkab tau muab tus lej cua sov, tus lej yeeb nkab, thiab GPS coordinates ntawm kev tsim khoom. Pab neeg QA ntawm tus neeg siv khoom tau tshuaj xyuas peb lub chaw ob zaug thaum lub sijhawm tsim khoom; ob qho kev tshuaj xyuas tau dhau los yam tsis muaj kev tsis ua raws li.
Qhov Tshwm Sim:Lub East African Crude Oil Pipeline (EACOP) tau teem sijhawm rau kev ua tiav hauv Q2 2025. Womic Steel 13,000 tons ntawm X52 PSL2 cov kav dej tau xa tuaj dhau 8 lub hlis (thawj zaug xa khoom Lub Kaum Hli 2023, zaum kawg xa khoom Lub Tsib Hlis 2024). Tag nrho cov kav dej tau dhau los ntawm kev tshuaj xyuas sab nraud los ntawm SGS Tanzania. Tus neeg siv khoom (ib lub koom haum ntawm cov tuam txhab roj thoob ntiaj teb) tau muab ib tsab ntawv qhuas rau Womic txoj kev tswj xyuas zoo thiab kev xa khoom raws sijhawm. Womic tam sim no yog tus neeg muab khoom ua ntej rau kev nthuav dav cov kav dej yav tom ntej hauv cheeb tsam.
