DSAW Kab Yeeb Nkab

DSAW Kab Kab Yeeb Nkab (Submerged Arc Welded Kab Yeeb Nkab Ua Kua Hlau Ua Haujlwm, uas yog siv dav hauv kev ncua ntev li roj thiab nkev.
---

1. Khoom npaj npaj
• Kev siv cov phiaj loj ntawm cov hlau (xws li API 5L X42 rau X80 Qib) raws li cov khoom siv raw, cov qauv kev ua haujlwm nruj me ntsis.

2. Kev sib sau thiab vuam
• Ua ntej los khoov thiab sib sau:

Tom qab cov khoom siv ua ntej ua ntej, lub phaj steel yog maj mam khoov rau hauv cov tshuab sib dhos los ntawm txoj kev sib sau tshuab (joge / UOE cov txheej txheem).

• Sab hauv thiab sab nraud vuam:
◦ Lub hauv paus sab hauv thiab sab nraud ntawm cov yeeb nkab steel yog subcerged arc technology, thiab arc tiv thaiv oxidation thiab xyuas kom nkag siab thiab kev sib tw.
◦ Lub puab vuam sab hauv yog ua tiav rau sab hauv ntawm lub raj thiab sab nraud vuam nyob sab nraud, muaj kev txhim khu kev txhawb siab ntau dua ib sab vuam).

3. Tom qab ua
• nthuav dav: hydraulic lossis kho tshuab tshem tawm cov kev ntxhov siab rau kev ntxhov siab thiab ua kom muaj kev sib txawv thiab sab qhov tseeb.
• Tsis yog kev sim ua tsis yog (NDT): siv Ultrasonic (UT), RT) lossis kev sim ua kom pom kev sib tw weld tsis xws luag.
• Cov txheej thiab tshuaj tiv thaiv corrosion: txheej epoxy cob (FBE), peb txheej ntawm polyethylene (3pe) thiab lwm yam kev tiv thaiv corrosion raws li cov tseev kom muaj.

1. Muaj zog thiab tawv
• Tsim nyog rau kev ua siab zoo conveying (tuaj yeem tiv taus ntau dua 10mpa ntau dua), cov khoom siv nce mus rau X80 (tawm los ntawm 550mpa).

2. Cov caliber thiab tuab phab ntsa
• Cov lus Specifications: Sab Nraud Inci {0}} hli, phab ntsa thickness {} mm 6-18 m.
• Tsim nyog rau kev tso cov kab tseem ceeb ntawm cov roj ntev ntev / roj av.

3. Lub siab vuam zoo
• Muab ob sab submerged arc vuam muaj qhov tob tob loj, ob peb yam tsis xws luag, thiab lub zog weld yog ze rau cov khoom siv.

4. Lub zog ib puag ncig kev yoog
• Tsim nyog rau qhov kub tsawg, muaj kev kub siab, zoo li cov raj xa dej hauv nkoj) thiab lwm yam mob hnyav.

• Roj thiab Gas Tsheb Thauj: Av thiab cov kav dej nyob ntev ntev (xws li WEN WEST-EAS EAS EAS EASE CARDER PIPELINES).
• Tshuaj Lom thiab Lub Zog: Tsheb thauj mus los ntawm liquefied nkev (lng), carbon dioxide, hydrogen, thiab lwm yam.
• Infrastructure:Cov dej num tseem ceeb phiaj xwm, lub zog kub siv hluav taws xob thiab lwm yam kev lom zem siab thiab ruaj khov.

• Cov Qauv Thoob Ntiaj Teb:API 5L (American Petroleum Lub Koom Haum), ISO 3183, DNV (Norske Veritas), thiab lwm yam.
• Yuav tsum muaj ib puag ncig ib puag ncig:HIC (tsis kam mus rau hydrogen cracking) thiab SSC (Sulfide kev nyuaj siab corrosion) yuav tsum muaj.

Qhov Zoo:
• Muaj zog weld zoo, haum rau kev kub siab, loj txaus conveying;
• Xav txog cov kev daws teeb meem rau cov kav dej loj uas muaj kev pabcuam ntev ntev (mus txog ntau dua 50 xyoo).

Qhov tsis zoo:
• Ntau Ntau Ntau Ntau Tshaj Laij thiab tus nqi siab;
• Cov kav dej uas hla me me tsis muaj kev lag luam tsawg dua li ERW.
