Cov Lus Nug Feem Ntau:

Q: Vim li cas ho xaiv X60 dua li X52 rau cov kav dej roj?
A: X60 muaj 15% siab dua qhov muaj zog (415 MPa vs 360 MPa), uas ua rau cov phab ntsa nyias dua (feem ntau yog 10-15% txo) rau tib qhov ntsuas siab. Qhov no txo qhov hnyav thiab tus nqi ntawm cov khoom siv, tshwj xeeb tshaj yog rau cov kav dej ntev. Txawm li cas los xij, X60 xav tau cov txheej txheem vuam nruj dua thiab muaj kev cuam tshuam ntau dua rau kev tawg hydrogen. Rau qhov siab hauv qab 10 MPa, X52 feem ntau pheej yig dua. Rau qhov siab saum toj no 12 MPa, X60 lossis X65 raug pom zoo.

Q: Qhov txawv ntawm X60 PSL1 thiab PSL2 yog dab tsi?
A: PSL2 muaj cov kev txwv tshuaj lom neeg nruj dua (tshwj xeeb tshaj yog qis dua C, P, S), kev sim cuam tshuam Charpy yuav tsum tau ua (27J @ 0 ° C lossis qis dua), qhov nyuaj siab tshaj plaws 90 HRB, thiab xav tau 100% UT ntawm qhov sib txuas (PSL1 tsuas yog xav tau qhov chaw UT). Rau cov kab roj ua haujlwm hauv thaj chaw muaj neeg coob lossis qhov kub qis, PSL2 feem ntau tau teev tseg.

Q: Koj puas tuaj yeem muab X60 nrog daim ntawv pov thawj kev pabcuam qaub?
A: Yog. Peb muab X60 PSL2 nrog HIC kev kuaj (NACE TM0284) thiab SSC kev kuaj (NACE TM0177). Kev lees txais ib txwm: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5% rau HIC. PWHT yog siv rau txhua qhov kev pabcuam qaub X60 tsis hais txog phab ntsa tuab kom ntseeg tau tias qhov nyuaj ≤ 85 HRB. Peb tau muab kev pabcuam qaub X60 rau Middle East thiab Southeast Asia cov haujlwm.

Q: Koj tuaj yeem ua qhov kev sim cuam tshuam qis-kub dab tsi rau X60 arctic pipelines?
A: Peb tuaj yeem sim mus txog -60 ° C. Cov kav dej roj arctic feem ntau xav tau Charpy impact ntawm 27J yam tsawg kawg nkaus ntawm -46 ° C. Womic feem ntau ua tiav 80-120J ntawm -46 ° C. Rau kev tswj kev tawg, peb kuj ua DWTT ntawm -20 ° C nrog yam tsawg kawg nkaus 85% shear cheeb tsam. Thov qhia koj qhov kub thiab lub zog xeem xav tau.

Q: Cov txheej txheem twg zoo tshaj plaws rau X60 cov kav dej hauv hiav txwv - JCOE lossis UOE?
A: UOE yog qhov zoo dua rau cov dej hiav txwv vim nws tsim cov duab zoo dua (± 0.2% vs ± 0.5% rau JCOE) thiab txo qhov kev ntxhov siab seem. Qhov no yog qhov tseem ceeb rau kev tiv taus qhov siab hydrostatic sab nraud (kev tawg) thiab rau kev vuam girth txhim khu kev qha ntawm cov nkoj tso. UOE kuj muab kev ua haujlwm qaug zog zoo dua rau cov dynamic risers. Rau cov dej ntiav (< 100m) ntawm ntug dej hiav txwv ze-ntug dej, JCOE yog qhov siv tau.

Q: Lub sijhawm ua cov yeeb nkab X60 LSAW feem ntau yog dab tsi?
A: Lub sijhawm ua tus qauv rau X60 PSL1: 35-50 hnub. Rau X60 PSL2 nrog kev sim kev pabcuam qaub thiab PWHT: 50-70 hnub. Kev txiav txim maj (25-35 hnub) ua tau rau cov khoom me me (< 1,000 tons) yog tias phaj muaj nyob hauv Tshuag. Rau cov xaj loj heev (> 20,000 tons), lub sijhawm ua tus qauv yuav ntev txog 90 hnub.

Q: Koj puas muab kev tshuaj xyuas sab nraud rau cov kav dej X60 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, nrog tus neeg sawv cev ntawm tus neeg siv khoom ua tim khawv. Peb muab daim ntawv pov thawj EN 10204 Hom 3.2 thaum thov.

Cov Lus Qhia Txog Qhov Project - Txoj Kab Tsheb Roj Av hla ciam teb sab hnub tuaj Asia

Lub Tebchaws:Thaj tsam ciam teb Myanmar - Thaib teb (cov kav dej roj los ntawm Gulf of Martaban mus rau Thaib teb)
Tus Qauv & Qib:API 5L X60 PSL2 (kev pabcuam qaub, nrog rau kev kuaj HIC thiab SSC)
Qhov Loj & Qhov Ntau:

●OD 813mm (32″) × WT 19.0mm – 36,000 meters (kwv yees li 12,600 tons) tsim los ntawm UOE txheej txheem

●OD 813mm (32″) × WT 22.0mm – 8,000 meters (kwv yees li 3,200 tons) tsim los ntawm UOE txheej txheem (phab ntsa tuab dua rau kev hla txoj kev/kev tsheb ciav hlau)

●OD 610mm (24″) × WT 15.9mm – 12,000 meters (kwv yees li 2,400 tons) tsim los ntawm JCOE txheej txheem (kab ceg mus rau lub chaw tsim hluav taws xob)
Tag Nrho:56,000 meters (56 km), kwv yees li 18,200 tons

Cov Lus Qhia:Txheej 3LPE sab nraud (3.0 hli tag nrho tuab) ib qho ISO 21809, beveled kawg 30 ° / 1.6 hli hauv paus ntsej muag nrog sab hauv bevel tiv thaiv, hydrotest ntawm 15.0 MPa (tsim siab 11.5 MPa). Yuav tsum muaj Charpy cuam tshuam ntawm 0 ° C thiab -20 ° C (min 27J, ua tiav 90-140J). HIC ib qho NACE TM0284 Tshuaj A, 96h - kev lees txais: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. SSC ib qho NACE TM0177 Txoj Kev A, 720h - tsis pub tawg. PWHT thov rau txhua lub kav dej nrog WT ≥ 19.0 hli. 100% automated UT nrog TOFD rau weld seam. Kev kuaj radiographic (RT) rau cov qauv kev tsim nyog weld teb.

Daim Ntawv Thov:Txoj kab roj av hla ciam teb thauj roj los ntawm cov teb hauv Gulf of Martakan (Myanmar) mus rau qhov chaw txais roj hauv Thaib teb, tom qab ntawd mus rau lub chaw tsim hluav taws xob siv roj. Ntu 56 km ntawm ntug dej hiav txwv hla cov roob hav zoov nrog kev hloov pauv siab heev (txog li 400m), ntxiv rau rau qhov kev hla txoj kev loj thiab peb qhov kev hla tsheb ciav hlau.

Cov Kev Sib Tw thiab Kev Dais Teeb Meem:

●Kev ua raws li kev pabcuam qaub rau cov roj uas muaj H₂S me me– Cov roj av muaj 5-10 ppm H₂S ntawm 55°C qhov kub thiab txias ua haujlwm. Womic tau ua qhov kev sim HIC thiab SSC ntawm 12 qhov chaw tsim khoom. Txhua qhov dhau nrog CLR 0%, CTR 0%, CSR 0% rau HIC. Kev sim SSC (NACE TM0177, 720h) tsis pom qhov tawg ntawm qhov chaw. Peb ua tiav qhov no los ntawm kev tswj CEV ≤ 0.38%, siv PWHT rau txhua lub kav dej 19.0mm thiab 22.0mm WT (txawm hais tias API 5L tsis xav tau PWHT qis dua 25.4mm), thiab tswj cov cua sov vuam rau ≤ 2.8 kJ / hli. Tus neeg soj ntsuam ntawm tus neeg siv khoom (BV) tau pom txhua qhov kev sim thiab tau lees paub cov txiaj ntsig.

●Thaj chaw roob nrog cov nkhaus ntev ntev– Txoj kev kav dej muaj cov nqes hav txog li 25 degrees. Kev khoov ntawm cov kav dej X60 hauv thaj chaw nyuaj dua li cov qib qis dua vim muaj zog dua. Womic muab cov kav dej nrog cov pob qij txha ntev ntxiv (18m es tsis yog tus qauv 12m) los txo cov lej ntawm cov khoov hauv thaj chaw los ntawm 33%. Peb kuj tau muab cov qauv tshwj xeeb bevel (compound bevel) uas tso cai rau ± 3 ° misalignment thaum lub sijhawm vuam hauv thaj chaw yam tsis muaj kev cuam tshuam rau qhov zoo ntawm weld. Ovality tau tuav rau ≤ 0.3% (UOE txheej txheem) kom ntseeg tau tias muaj kev sib dhos zoo ntawm cov nqes hav.

●Kev ua kom zoo ntawm 3LPE txheej hauv hav zoov– Cov av noo siab (80-95% thoob plaws hauv ib xyoos) thiab cov av laterite uas muaj zog ua rau muaj kev pheej hmoo ntawm cov txheej txheej. Womic tau siv 3LPE txheej nrog ib txheej ntxiv 0.3 hli. Peb tau ua qhov kev kuaj pom hnub so 100% ntawm 7kV (tus qauv 5kV) thiab ntsuas lub zog tev tawv ntawm 25 ° C thiab 70 ° C (230 N / cm ntawm 25 ° C, 160 N / cm ntawm 70 ° C). Cov txheej txheem dhau qhov kev sim cathodic disbondment (≤ 8mm radius ntawm 65 ° C, 28 hnub).

●Kev thauj mus los hla ciam teb nrog kev nyuaj ntawm kev lis kev cai– Cov kav dej tau raug xa los ntawm Shanghai mus rau chaw nres nkoj Yangon (Myanmar), tom qab ntawd thauj khoom mus 280 km mus rau cov kav dej uas nyob ze ciam teb Thaib. Txoj kev hla dhau ob lub chaw kuaj xyuas kev lis kev cai. Womic tau npaj cov ntaub ntawv tshwj xeeb rau lub tebchaws (Daim Ntawv Pov Thawj Keeb Kwm los ntawm AK, thoob plaws ASEAN). Peb kuj tau npaj cov ntawv cog lus xa khoom ib ntus kom tsis txhob them se qeeb. Tag nrho 18,200 tons tau dhau kev lis kev cai hauv 5 hnub.

●Kev tswj hwm cua sov vuam rau X60– X60's HAZ rhiab heev rau qhov kub ntau dhau, uas tuaj yeem ua rau mos thiab txo qhov tawv. Womic siv lub kaw lus SAW ob txoj hlua nrog kev saib xyuas qhov kub ntawm txhua qhov vuam hla. Qhov nruab nrab ntawm qhov kub rau sab hauv vuam: 2.2 kJ / hli, vuam sab nraud: 2.5 kJ / hli (qis dua 3.5 kJ / hli txwv). Qhov kub ntawm qhov sib tshuam tau khaws cia qis dua 200 ° C. Qhov nyuaj ntawm kev vuam hla tom qab PWHT: hlau puag 78-82 HRB, vuam 82-86 HRB, HAZ 80-84 HRB - txhua yam nyob hauv 90 HRB txwv.

● Qhov Tshwm Sim:Cov kav dej roj tau pib ua haujlwm hauv Q3 2024. Tag nrho 56 km ntawm X60 PSL2 kav dej tau dhau los ntawm kev tshuaj xyuas sab nraud los ntawm BV Myanmar. Tus neeg siv khoom tau tshaj tawm xoom qhov tsis zoo ntawm kev vuam thaum lub sijhawm vuam girth (ntau dua 4,600 girth welds). Cov kav dej tau ua haujlwm ntawm 10.5-11.0 MPa rau 12 lub hlis tsis muaj qhov xau lossis txheej tsis ua haujlwm. Womic Steel tau txais khoom plig "Tus Neeg Muab Khoom ntawm Lub Xyoo" los ntawm tus neeg cog lus EPC Thaib rau kev xa khoom raws sijhawm (tag nrho 18,200 tons xa tuaj hauv 68 hnub) thiab kev ua tau zoo.
