1. Dab tsi yog SSAW Carbon Steel Pipe?
Teb:SSAW yeeb nkab yog Kauv Submerged Arc Welded carbon steel yeeb nkab. Nws yog tsim los ntawm helically coiling kub - dov steel kauj thiab vuam cov seam ib txhij los ntawm sab hauv thiab sab nraud siv cov txheej txheem submerged arc vuam (SAW). Txoj kev no tso cai rau kev tsim cov kav dej loj - txoj kab uas hla los ntawm cov hlau uas nqaim los yog coils-1.
2. Dab tsi yog qhov zoo ntawm SSAW kav dej?
Teb:Ib qho txiaj ntsig tseem ceeb yog qhov muaj peev xwm tsim tau ntau yam diameters los ntawm ib qho lossis txwv dav ntawm steel sawb. Lawv kuj muaj zog vim lawv qhov txuas txuas txuas ntxiv, uas tuaj yeem pab tswj cov kab nrib pleb -1. Tsis tas li ntawd, lawv feem ntau raug nqi - zoo rau daim ntawv thov loj.
3. Dab tsi yog qhov kev txwv lossis qhov tsis xws ntawm cov kav dej SSAW?
Teb:SSAW kav dej muaj ntau yam kev txwv, suav nrog:
Cov teeb meem Geometric:Cov hlau kauj tuaj yeem muaj "ntsuab khoov", uas ua rau nyuaj rau kev tsim cov txheej txheem-1.
Weld Defects:Lub kauv weld yog ua rau ntawm qhov hloov pauv, inclined nto, ua rau muaj qhov tshwm sim ntau dua ntawm vuam sib txawv, kev ntxhov siab sab hauv, thiab qhov tsis xws luag xws li tawg, tsis muaj kev nkag mus, thiab tsis muaj fusion-1-8.
Mechanical Performance:Lub kauv seam tuaj yeem ua rau cov neeg kho tshuab tsis zoo tiv thaiv kev khoov thiab flattening piv rau ncaj-seam kav-1.
Thickness txwv:Cov txheej txheem kauv feem ntau txwv qhov siab tshaj plaws phab ntsa thickness mus txog 16-18 mm-1.
4. Cov ntawv thov twg yog cov kav dej SSAW feem ntau siv?
Teb:SSAW kav yog dav siv nyob rau hauv lubroj thiab natural gas kev lag luamrau ntev - kis tau tus mob kav-7. Lawv kuj feem ntau siv rau hauv cov dej num, piling, kev siv cov qauv, thiab kev lag luam chemical-1-10.
5. SSAW yeeb nkab piv rau LSAW (Longitudinal Submerged Arc Welded) yeeb nkab li cas rau kev xa cov roj thiab roj?
Teb:Muaj qhov sib txawv thoob ntiaj teb nyiam LSAW cov kav dej hla SSAW rau cov haujlwm tseem ceeb roj thiab roj. LSAW kav (xws li cov ua los ntawm UOE los yog JCOE txheej txheem) feem ntau muaj kev ntseeg siab dua, zoo weld zoo, thiab superior mechanical zog. Kev txheeb xyuas los ntawm 1970-1980 tau pom tias hauv cov phiaj xwm thoob ntiaj teb, LSAW suav txog 55%, thaum SSAW tsuas yog suav txog 4%-7%-1. Ntau lub tebchaws txwv tsis pub SSAW cov kav dej rau thaj chaw tsis tseem ceeb (chav kawm 1 cheeb tsam) thiab siv LSAW rau ntau qhov chaw xav tau (Class 2, 3, 4, thiab offshore)
