Distinguishing ntawm welded thiab seamless steel kav yog ib txoj haujlwm tseem ceeb rau txhua tus neeg ua haujlwm hauv kev lag luam steel.Nrog rau ntau yam sib txawv ntawm cov yeeb nkab steel nyob rau hauv kev ua lag luam, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem thiab cov txheej txheem tsim nyog los txheeb xyuas cov yeeb nkab steel siv los yog yuav khoom.Kab lus no tham txog cov txheej txheem siv los txheeb xyuas cov yeeb nkab steel, thaum tsom mus raucarbon SSAW steel yeeb nkab, kauv welded steel yeeb nkab, thiab carbon SSAW nqi.
Ib txoj hauv kev tseem ceeb kom paub qhov txawv welded steel kav los ntawmseamless steel kavyog los xyuas cov txheej txheem ntau lawm.Seamless steel kavyog tsim tsis muaj welding whereas welded steel kav yog tsim los ntawm welding steel strips los yog daim hlau ua ke.Carbon steel SSAW yeeb nkab, piv txwv li, yog tsim los ntawm winding kub-kuav los tiag steel sawb nyob ib ncig ntawm ib tug series ntawm txoj kev yob los tsim ib tug helical seam, uas yog ces welded ua ke.Cov txheej txheem ntau lawm tuaj yeem cuam tshuam rau lub cev ntawm cov kav dej steel.
Lwm txoj hauv kev los txheeb xyuas cov yeeb nkab steel yog saib ntawm qhov chaw ntawm cov yeeb nkab.Yog tsis pom seams rau saum npoo ntawmseamless steel kav, thaum muaj cov seams pom nyob rau saum npoo ntawm welded steel kav.Kauv welded steel kav muaj ib tug tshwj xeeb kauv qauv, uas ua rau lawv yooj yim kom paub qhov txawv ntawm lwm yam steel kav.Tsis tas li ntawd, cov nqi carbon SSAW tuaj yeem cuam tshuam qhov zoo thiab cov yam ntxwv ntawm cov kav dej steel.
Ntxiv nrog rau cov kev sib tham saum toj no, cov kev sim tsis muaj kev puas tsuaj (NDT) kuj tuaj yeem siv los txheeb xyuas cov raj hlau.Qee txoj hauv kev NDT nrov suav nrog Magnetic Particle Inspection (MPI), Ultrasonic Testing (UT) thiab Radiography.Cov txheej txheem no yog siv los txheeb xyuas qhov tsis zoo lossis teeb meem hauv cov yeeb nkab steel yam tsis muaj kev puas tsuaj rau cov yeeb nkab.
Hauv kev xaus, kev txheeb xyuas kom raug ntawm welded thiab seamless steel kav yog qhov tseem ceeb rau txhua tus neeg ua haujlwm hauv kev lag luam steel.Carbon SSAW Steel Pipe, Spiral Welded Steel Pipe, thiab Carbon SSAW Nqe yog hom nrov tshaj plaws ntawm cov yeeb nkab steel niaj hnub no.Kev nkag siab txog cov txheej txheem siv los txheeb xyuas cov kav hlau no yog qhov tseem ceeb los xyuas kom meej qhov kev xaiv raug thiab siv cov kav hlau steel uas ua tau raws li cov kev cai tshwj xeeb ntawm kev lag luam sib txawv.Txhua tus kav hlau kav lossis cov neeg siv khoom tuaj yeem tau txais txiaj ntsig los ntawm kev paub txog ntau yam kev txheeb xyuas thiab cov yam ntxwv ntawm cov yeeb nkab steel sib txawv kom ntseeg tau tias cov kev daws teeb meem zoo dua, raug nqi thiab cov txiaj ntsig zoo.
