Cov yeeb nkab uas muaj ob sab submerged arc welded thiab ncaj seam yogCov yeeb nkab JCOECov yeeb nkab hlau ncaj nraim raug muab faib ua ob hom raws li cov txheej txheem tsim khoom: cov yeeb nkab hlau ncaj nraim uas muaj zaus siab thiab cov yeeb nkab hlau ncaj nraim uas muab tso rau hauv qab dej arc welded JCOE. Cov yeeb nkab hlau ncaj nraim uas muab tso rau hauv qab dej arc welded raug muab faib ua UOE, RBE, JCOE,Cov kav hlau LSAW, thiab lwm yam raws li lawv txoj kev tsim. Cov txheej txheem tsim cov yeeb nkab JCOE yog qhov yooj yim, nrog rau kev ua haujlwm siab, cov nqi qis, thiab kev txhim kho sai.
Cov yeeb nkab JCOE yog ib qho ntawm cov yeeb nkab hlau ncaj nraim, thiab yog ib qho ntawm cov khoom siv. Hauv Suav teb, GB/T3091-2008 thiab GB/T9711.1-2008 siv dav, thaum API-5L yog tus qauv thoob ntiaj teb. Cov yeeb nkab JCOE feem ntau yog tsim los ntawm kev siv ob sab submerged arc welding. Txhawm rau kom ua tau raws li cov kev cai ntawm cov qauv cuam tshuam, cov khoom lag luam mus dhau ntau yam txheej txheem xws li khoov, sib koom ua ke, vuam sab hauv, vuam sab nraud, ncaj, thiab tiaj tiaj.
Cov phiaj xwm loj ntawm cov kav dej, cov phiaj xwm xa dej thiab roj, kev tsim kho cov kav dej hauv nroog, cov tsev tsim kho hlau, kev teeb tsa choj, kev tsim kho hauv nroog, thiab kev tsim kho hauv nroog txhua tus siv cov kav dej JCOE.
Qhov hnyav mis: [(sab nraud txoj kab uas hla-phab ntsa tuab) * phab ntsa tuab] * 0.02466 = kg / m (qhov hnyav ib 'meter').
Q235A, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X70, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, thiab lwm yam ntaub ntawv feem ntau siv.
Tsis pub muaj qhov quav, tawg, tawg, vuam lap, tawg arc, hlawv, lossis lwm yam teeb meem hauv zos uas qhov tob tshaj qhov sib txawv qis ntawm phab ntsa raug tso cai rau ntawm sab hauv thiab sab nraud ntawm JCOE cov kav hlau ncaj. Lwm yam teeb meem hauv zos nrog qhov tob uas tsis tshaj qhov sib txawv qis ntawm phab ntsa raug tso cai.
