Carbon Steel Welded Yeeb Nkab
Butt-welded yeeb nkab yog tsim los ntawm kev pub ib lub phaj kub steel los ntawm shapers uas yuav yob nws mus rau hauv lub hollow voj voog.Kev quab yuam ob qhov kawg ntawm lub phaj ua ke yuav tsim ib qho kev sib koom ua ke los yog seam.Daim duab 2.2 qhia cov hlau phaj thaum nws pib txheej txheem ntawm kev sib sau taub qab-welded yeeb nkab
Tsawg tshaj plaws ntawm peb txoj kev yog kauv-welded yeeb nkab.Kauv-welded yeeb nkab yog tsim los ntawm twisting strips ntawm hlau mus rau hauv ib tug kauv zoo, zoo li ib tug barber.'s ncej, ces welding qhov twg cov npoo koom ib leeg los ua ib tug seam.Hom yeeb nkab no yog txwv tsis pub siv cov kav dej uas tsis tshua muaj siab vim nws cov phab ntsa nyias.Daim duab 2.3 qhia tau hais tias kauv-welded yeeb nkab raws li nws tshwm sim ua ntej vuam.
Txhua ntawm peb txoj kev tsim cov yeeb nkab muaj nws qhov zoo thiab qhov tsis zoo.Butt-welded yeeb nkab, piv txwv li, yog tsim los ntawm dov phaj uas muaj cov phab ntsa zoo dua qub thiab tuaj yeem kuaj xyuas qhov tsis xws luag ua ntej kev tsim thiab vuam.Txoj kev tsim khoom no yog qhov tshwj xeeb tshaj yog thaum cov phab ntsa nyias thiab ntev ntev xav tau.Vim hais tias ntawm cov welded seam, txawm li cas los xij, yeej ib txwm muaj peev xwm ntawm qhov tsis xws luag uas khiav tawm ntau qhov kev tswj xyuas zoo tau ua thaum lub sijhawm tsim khoom.
Yog li ntawd, lub koom haum American National Standards Institute (ANSI) tau tsim cov txheej txheem nruj rau kev tsim cov yeeb nkab.Siab Piping Code B31 tau sau los tswj kev tsim cov yeeb nkab.Tshwj xeeb, code B31.1.0 muab lub zog ntawm 85% rau cov yeeb nkab dov, 60% rau cov kav hlau txuas, thiab 100% kev ua haujlwm zoo rau cov yeeb nkab seamless.
Feem ntau, dav phab ntsa thicknesses yog tsim los ntawm txoj kev seamless.Txawm li cas los xij, rau ntau qhov kev siv cov yeeb nkab uas tsis tshua muaj siab, txoj kev nruam welded yog qhov kev lag luam tshaj plaws.Seamless yeeb nkab yog tsim nyob rau hauv ib leeg thiab ob chav random lengths.Ib qho random ntev sib txawv ntawm 16'-0″rau 20'-0″.Cov kav dej 2″thiab hauv qab no pom nyob rau hauv ob chav random ntev ntsuas los ntawm 35'-0″rau 40'-0″.
