1. Dab tsi yog qhov txawv ntawm "Bare Pipe" thiab "Coated & Lined Pipe"?
A: Yeeb Nkabyog cov yeeb nkab raws li nws los ntawm kev tsim cov kab, nrog cov kua roj vanish zeb tab sis tsis muaj kev tiv thaiv -corrosion txheej.Coated & Lined Pipemuaj cov txheej txheem sab nraud thiab / lossis cov txheej txheem sab hauv, uas yog tus qauv rau kev xa khoom.
2. Leej twg yog cov tuam txhab lag luam loj thoob ntiaj teb ntawm LSAW kav?
A:Cov neeg tsim khoom loj yog nyob rau sab hnub tuaj Asia (Tuam Tshoj, Nyiv, Kaus Lim Qab Teb), Europe, thiab Is Nrias teb. Piv txwv xws li Vallourec, Tenaris, Jindal SAW, Europipe, thiab ntau lub tuam txhab suav loj.
3. Cov kav dej LSAW thauj mus li cas?
A:Vim lawv qhov loj me thiab qhov hnyav, lawv feem ntau yog thauj los ntawmnkojrau kev lag luam thoob ntiaj teb. Hauv av, lawv tau tsiv los ntawm hnyav- tsheb thauj khoom lossis, qee zaum, los ntawm kev tsheb ciav hlau.
4. Cov ntaub ntawv dab tsi feem ntau yog muab nrog kev xa khoom ntawm LSAW kav dej?
A:Ib qho tseem ceeb "Mill Test Certificate" (MTC) lossis "Certificate of Conformity" yog muab, uas qhia meej txog cov tshuaj ntsuam xyuas, cov khoom siv kho tshuab, thiab cov txiaj ntsig ntawm txhua qhov tsis yog -kev ntsuas kev puas tsuaj thiab hydrostatic rau qhov kub / cov yeeb nkab.
5. Dab tsi yog yav tom ntej kev sib tw rau LSAW yeeb nkab tshuab?
A:Cov qauv yog mus rau kev tsim cov kav dej los ntawmtxawm siab dua -qib steels (X80, X100, X120)tso cai rau kev sib kis ntau dua thiab txo cov khoom siv. Kuj tseem muaj kev tsom ntsoov rau kev txhim kho cov tawv tawv rau cov ntawv thov hauv arctic thiab txhim kho kev tiv thaiv -corrosion coatings rau lub neej ntev kev pab cuam.
