Kev tsim khoom
- API 5L:Qhov yuav tsum tau muaj thoob ntiaj teb tus qauv rau cov roj thiab cov kav xa hluav taws xob.
- PSL2:Qib siab -tus qauv zoo; lub luag hauj lwm specification rau mainline thiab subsea pipelines.
- LSAW:Tsim los ntawm steel phaj dabtsi yog khoov thiab ob -sided (sab hauv thiab sab nraud) submerged arc vuam; nta ib longitudinal weld seam; thawj hom yeeb nkab rau loj - txoj kab uas hla, siab - cov kav dej siab.
- Qhov chaw:Lub siab tseem ceeb- bearing steel yeeb nkab ua tau raws li cov qauv kev nyab xeeb siab tshaj plaws rau ntev -cov roj thiab cov roj xa mus rau lub ntsiab; cais raws li Qib I siab-cov kabmob tivthaiv rau cov kav dej siab.
Tsim cov txheej txheem (ob txoj hauv kev tseem ceeb: UOE thiab JCOE)
- Txheej txheem UOE:U-nias → O-kaw → mechanical cold expanding. Cov yam ntxwv siab kev ua siab ntev, haum rau kev tsim khoom loj ntawm cov qauv yeeb nkab loj (508-1220 hli OD)
- JCOE Txheej Txheem:Progressive segmented dabtsi yog khoov sib sau nrog cov cuab yeej siv qis dua. Muaj feem xyuam rau cov kav dej tuab - phab ntsa, tsis yog - tus qauv diameters thiab cov khoom me me - batch xaj (OD: 406-1422 hli, max phab ntsa thickness txog 70 hli)
JCOE Production Process
Cov txheej txheem tsim khoom UOE
Loj Specifications
- Sab nraud Diameter Range:NPS 16"-NPS 84" (406mm-2134mm); hom yeeb nkab zoo rau qhov loj - txoj kab uas hla, siab - cov kav dej siab.
- Phab ntsa Thickness:Txheem SCH 20 / SCH 40 / SCH 80; nce phab ntsa thickness muaj raws li qhov kev thov.
- Fixed Lengths:6 m, 12 m, 18 m; kev cai txiav rau qhov project- qhov ntev tshwj xeeb kuj muaj.
- Pipe End Hom:Beveled End (BE) rau qhov chaw vuam, Plain End (PE) rau flange kev twb kev txuas. Lub kaus mom yas yeeb nkab tau nruab los tiv thaiv kev sib tsoo puas thiab cuam tshuam cov khoom txawv teb chaws.
Sab nrauv Anti-Txoj kev xaiv txheej txheej txheej (30+ xyoo tsim kev pab cuam lub neej rau cov kav dej faus)
| Txheej hom | Txuag Standard | Daim ntawv thov Scenario | Kev khiav hauj lwm qhov kub thiab txias |
|---|---|---|---|
| Ib - txheej FBE | ISO 21809, NACE RP0394 | High -kub pipelines, subsea field coating coatings | -30℃~ 110 degree |
| 3LPE (3-txheej Polyethylene) | DIN30670 | Onshore trunk pipelines nrog zoo heev av abrasion kuj & nqi kev ua tau zoo | -40℃~ 80 degree |
| 3LPP (3-txheej Polypropylene) | ISO 21809 | Siab -kub nruab nrab kev thauj mus los, cov kav dej hauv qab hiav txwv & cov pob zeb hauv hiav txwv uas muaj kev pheej hmoo siab | -40℃~ 140 degree |
- Cov kav dej liab qab tsuas yog siv rau luv luv ntawm - cov kav dej ntawm qhov chaw.Sab nrauv los tiv thaiv-corrosion txheej yog qhov tseem ceeb rau qhov ntev - cov kav xa hluav taws xob. Sab hauv rub-txo epoxy txheej yog xaiv tau rau kev xa cov roj crude kom txo kev siv zog thauj mus los.
Main Application Fields
- Onshore tej yaam num:Hla - ciam teb cov pa roj carbon monoxide kab, roj av ntev - cov kav dej nyob deb, nroog siab - cov kav dej siab siab, CCUS CO₂ cov kav xa dej
- Offshore Services:Subsea roj & roj pipelines, offshore platform risers, subsea sib sau ua ke pipelines (PSL2 yog ib tug yuam qib rau subsea pipelines)
- Cov xwm txheej tshwj xeeb ua haujlwm:Cov kav dej qaub uas muaj H₂S, cov kav dej hauv cov av khov & thaj chaw khov, siab - cov kav dej ua kom zoo dua cov roj xa mus
Cov yeeb nkab siv tau
Qhov zoo thiab qhov tsis zoo vs ERW, Seamless yeeb nkab & SSAW kauv yeeb nkab
-
Sib piv nrog ERW yeeb nkab:Muaj peev xwm ntawm txoj kab uas hla loj & hnyav phab ntsa ntau lawm nrog ntau dua siab ua hauj thiab superior weld kev ncaj ncees, muaj feem xyuam rau siab - siab trunk kis pipelines
-
Sib piv nrog SSAW kauv yeeb nkab:Ib qho kev sib txuas ncaj ncaj ua rau muaj kev sib txawv ntawm kev ntxhov siab, qhov tseeb dua qhov tseeb thiab nruj dua NDT kev lees paub. SSAW cov kav dej feem ntau yog siv rau qis- cov kav dej hauv nroog siab thaum qib PSL2 tsis tshua pom zoo rau cov kav dej hauv lub cev.
