Lub ntsiab sib txawv ntawm ob welded kav ntawm kauv welded yeeb nkab thiab ncaj welded yeeb nkab yog qhov sib txawv ntawm vuam daim ntawv.

Kauv welded yeeb nkab yog cov pa roj carbon tsawg tsawg lossis cov hlau tsis tshua muaj cov qauv hlau uas tau dov rau hauv lub raj tsis muaj lub kaum ntse ntse (tseem hu ua lub kaum sab xis), thiab tom qab ntawd welded thiab ua rau hauv cov yeeb nkab sib koom ua ke, uas tuaj yeem siv txoj hlua nqaim. steel Ntau txoj kab uas hla loj steel kav.Kauv welded yeeb nkab yog tsuas yog muab kauv submerged arc welded yeeb nkab (SSAW), uas yog nquag siv nyob rau hauv kev tsim kho ntawm ntau yam roj pipelines nyob rau hauv Tuam Tshoj.Nws cov lus qhia tshwj xeeb tau hais los ntawm "sab nraud txoj kab uas hla * phab ntsa thickness".Kauv welded kav yog ib sab welded thiab ob sab welded.Lub welded yeeb nkab yuav tsum xyuas kom meej tias qhov kev ntsuam xyuas hydraulic thiab lub zog tensile thiab txias bending kev ua tau zoo ntawm cov vuam yog ua raws li cov kev cai.

Qhov ncaj seam welded yeeb nkab yog ib tug high-frequency tam sim no thiab ib tug sib thooj nyhuv kauj ruam uas yuav tsum tau generated los ntawm lub solder txheej ua ntej lub vuam yog tsim los ntawm lub tshuab molding, thiab lub ntug ntawm lub raj yog rhuab thiab melted, thiab fused. nyob rau hauv ib tug tej yam pressing quab yuam, txias molding.Lub high-frequency ncaj seam welded yeeb nkab yog siv nyob rau hauv uas lub ntug ntawm cov yeeb nkab yog melted los ntawm high-frequency tam sim no (ERW), uas yog hu ua ib tug ncaj seam submerged arc welded yeeb nkab (LSAW) los ntawm melting nrog ib tug hluav taws xob arc.

Lub zog ntawm cov kauv welded yeeb nkab feem ntau yog siab tshaj qhov ncaj welded yeeb nkab.Cov txheej txheem tseem ceeb yog submerged arc vuam.Cov kav hlau welded tuaj yeem tsim cov kav dej sib txawv nrog cov yeeb nkab sib txawv nrog qhov dav ntawm qhov khoob, thiab tseem tuaj yeem tsim cov kav hlau txuas nrog cov kab loj dua nrog cov khoob khoob.

Cov txheej txheem ntau lawm ntawm txoj kab ncaj nraim welded yeeb nkab yog qhov yooj yim, feem ntau yog nyob rau hauv cov txheej txheem ntau lawm, uas tau muab faib ua high-frequency welded ncaj seam welded yeeb nkab thiab submerged arc welded ncaj welded yeeb nkab.Qhov ncaj seam welded yeeb nkab muaj kev ua haujlwm siab, tus nqi qis thiab kev loj hlob sai.

Txawm li cas los xij, piv nrog cov yeeb nkab ncaj welded yeeb nkab ntawm tib qhov ntev, qhov ntev vuam yog nce los ntawm 30 mus rau 100, thiab cov khoom ceev yog tsawg.Yog li ntawd, cov kab me me welded kav feem ntau ncaj seam welded, thaum lub taub loj welded kav feem ntau muab kauv welded.
