Hauv kev lag luam steel yeeb nkab, cov ntsiab lusLSAWthiabDSAWnquag siv ua ke, ua rau ntau tus neeg yuav khoom xav tias lawv sawv cev rau ob hom sib txawv ntawm cov yeeb nkab. Hauv kev muaj tiag, kev sib raug zoo ntawm ob lo lus no feem ntau to taub yuam kev. LSAW (Longitudinal Submerged Arc Welded) yog hais txog kev taw qhia ntawm lub vuam seam, thaum DSAW (Double Submerged Arc Welded) piav txog cov txheej txheem vuam siv thaum tsim khoom. Kev nkag siab txog qhov sib txawv yog qhov tseem ceeb rau cov kws tshaj lij, cov kws tshaj lij kev muag khoom, thiab cov tswv lag luam thaum xaiv cov kav hlau rau cov roj thiab cov roj xa mus, kev tsim hluav taws xob sab nrauv, cov kav dej, thiab cov chaw tsim khoom.
Cov kav dej niaj hnub xav tau cov khoom lag luam uas muaj kev ncaj ncees zoo heev, qhov tseeb ntawm qhov ntev, thiab kev ntseeg siab ntev ntev. Paub tias LSAW thiab DSAW muaj feem cuam tshuam li cas pab cov neeg yuav khoom ntsuas cov kev qhia tshwj xeeb kom raug thiab sib txuas lus zoo dua nrog cov tuam txhab.

Txawm hais tias cov ntsiab lus hais txog ntau yam ntawm kev tsim khoom, lawv muaj kev sib raug zoo hauv kev tsim LSAW niaj hnub.
Dab tsi yog Daim Ntawv Thov ntawmLSAW Steel Pipes?
LSAW steel yeeb nkab tau dav lees paub rau nws lub peev xwm los pab xav tau kev tsim vaj tsev ib puag ncig uas xav tau lub zog siab thiab ua haujlwm siab zoo. Vim tias nws yog tsim los ntawm steel phaj es tsis yog steel kauj, LSAW yeeb nkab tuaj yeem ua tiav qhov loj dua thiab cov phab ntsa tuab dua li ntau lwm cov khoom siv welded yeeb nkab.
Cov ntawv thov xws li kev xa cov roj av, cov raj xa hluav taws xob, LNG tau txais cov davhlau ya nyob twg, cov chaw tawm sab nrauv, kev tsim kho FPSO, kev xa dej hauv nroog, cov haujlwm tsuas, cov chaw petrochemical, cov chaw nres nkoj hauv hiav txwv, cov choj hauv paus, thiab loj - txoj kab uas hla steel yeeb nkab piling.
Qhov zoo ntawm qhov sib xws ntawm LSAW steel yeeb nkab ua kom yooj yim rau kev vuam thiab kev teeb tsa, ua rau nws tshwj xeeb tshaj yog tsim rau cov haujlwm uas muaj ntau txhiab tons ntawm cov khoom siv.
LSAW Steel Yeeb Nkab: 5 Cov Lus Qhia Tseem Ceeb rau Kev Yuav
Nkag siab qhov sib txawv ntawm LSAW thiab DSAW tsuas yog ib feem ntawm kev xaiv cov khoom raug. Cov kws tsim khoom kuj tseem yuav tsum ntsuas ntau qhov kev qhia tshwj xeeb tseem ceeb ua ntej yuav khoom.
Xaiv Txoj Cai Tsim Qauv
International qauv xws liAPI 5L, ASTM A671 Cov Lus Qhia Tshwj Xeeb, ASTM A672 Cov Lus Qhia Tshwj Xeeb, thiabGB/T 9711Txhais cov kev xav tau rau cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, qhov ntev ntev, cov txheej txheem kuaj, thiab kev tsim khoom zoo. Xaiv tus qauv tsim nyog nyob ntawm qhov project qhov kev khiav hauj lwm siab, thauj nruab nrab, thiab tus tswv specifications.
Qib steel yog qhov tseem ceeb sib npaug. Cov qib uas muaj xws liL245, L360M, X52, X60, X65, thiabX70, txhua qhov muab cov qib sib txawv rau ntau yam kev siv engineering.
Txoj kab uas hla, phab ntsa tuab, thiab kev tiv thaiv corrosion kuj yuav tsum tau ua tib zoo ua tib zoo saib xyuas cov kev ua haujlwm kom ua kom lub neej ua haujlwm siab tshaj plaws thiab txo cov nqi tu.
Yog vim li cas Welding Quality Determines Pipeline Reliability
Qhov zoo ntawm submerged arc vuam muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov kav dej. Kev ruaj ntseg vuam tsis zoo, cov khoom siv hluav taws xob kom zoo, kev npaj qhov zawj, thiab cov txheej txheem tshuaj xyuas tag nrho ua rau muaj peev xwm tsim cov welds muaj peev xwm tiv taus ntau xyoo ntawm kev ua haujlwm tsis tu ncua.
Cov neeg tsim khoom nruab nrog lub tshuab vuam tsis siv neeg, kuaj ultrasonic, kuaj hluav taws xob, ntsuas hydrostatic siab, thiab cov cuab yeej siv tshuab nthuav dav zoo dua los muab cov khoom zoo sib xws rau cov haujlwm loj thoob ntiaj teb.
Yog TxhuaLSAW TubePuas yog DSAW Pipe?
Ib qho ntawm cov lus nug ntau tshaj plaws hauv kev lag luam pipeline yog seb txhua qhov LSAW yeeb nkab puas yog DSAW yeeb nkab. Cov lus teb yognyob rau hauv feem ntau niaj hnub manufacturing txheej txheem, yog.
LSAW piav txog qhovlongitudinal weld configuration, hos DSAW piav txog qhovob chav submerged arc vuam txheej txheem, qhov twg ob sab hauv thiab sab nraud weld seams tiav siv submerged arc vuam.
Vim hais tias feem ntau siab - zoo LSAW steel kav yog tsim los siv sab hauv thiab sab nraud submerged arc vuam, lawv feem ntau raug piav raws li ob qho tib siLSAW tubthiabDSAW tub. Txawm li cas los xij, ob lo lus tsis sib hloov vim lawv hais txog cov tswv yim sib txawv.
Kev nkag siab txog qhov sib txawv no tso cai rau pawg neeg yuav khoom los txhais cov ntaub ntawv kev txawj ntse dua thiab sib txuas lus kom meej meej thaum lub sij hawm ntsuam xyuas tus neeg muag khoom.
Yam khoom piav qhia yog ntau dua nyob rau hauv International Projects?
Hauv kev xyaum engineering thoob ntiaj teb,LSAW steel yeeb nkabyog lub npe khoom lag luam uas siv ntau dua. Cov kev qhia tshwj xeeb, cov ntaub ntawv sib tw, thiab cov ntawv cog lus yuav khoom feem ntau piav qhia cov khoom raws li LSAW steel yeeb nkab vim tias qhov kev sib txuas ntev ntawm qhov sib txawv ntawm ERW thiab SSAW cov khoom.
Lub sij hawm DSAW feem ntau siv thaum hais txog cov txheej txheem vuam nws tus kheej lossis sib tham txog kev tsim khoom thiab vuam zoo.
Rau cov khoom siv tswv yim, cov neeg yuav khoom yuav tsum tsom mus rau cov khoom lag luam kom tiav, suav nrog cov qauv tsim, qib steel, qhov ntev, qhov yuav tsum tau soj ntsuam, txheej txheej txheej, thiab cov ntawv pov thawj zoo es tsis txhob cia siab rau cov lus siv xwb.
Txoj Haujlwm Siv: Libya Waha Oil Company Pipeline Project
Ib qho piv txwv zoo qhia tau hais tias qhov tseem ceeb ntawm siab - zoo LSAW manufacturing yog qhovLibya Waha Roj Tuam Txhab Crude Roj Pipeline Project, qhov twg Huayang Steel Pipe muab kwv yees li14,147,03 tLSAW steel yeeb nkabtsim raws liAPI 5L X52MS PSL2, nrog ib tug specification ntawm762 × 9.53 hli.
Lub phiaj xwm xav tau cov kav hlau uas muaj peev xwm thauj cov roj av mus ntev thaum tswj hwm qhov tshwj xeeb weld zoo, qhov sib xws, thiab siab ua haujlwm. Vim tias txoj haujlwm xav tau kev ua haujlwm, kev tsim khoom nruj, kev ua tsis zoo -kev kuaj kev puas tsuaj, kev ntsuas hydrostatic siab, thiab txhim khu kev qha submerged arc vuam yog qhov tseem ceeb thoob plaws hauv kev tsim khoom.
Siv cov txheej txheem JCOE siab heev thiab tsis siv neeg ob chav submerged arc vuam, cov khoom siv tau ua tiav raws li qhov project cov kev qhia tshwj xeeb thiab kev tsim kho. Qhov project no qhia txog qhov kev tsim khoom zoo thiab cov cuab yeej siv vuam zoo li cas pab ncaj qha rau lub sijhawm ntev - kev ntseeg siab ntawm cov kav dej thoob ntiaj teb loj.
