ASTM A519 steel yeeb nkab
Cov yeeb nkab no npog rau ntau qib ntawm carbon thiab alloy steel mechanical tubing, kub-tiav lossis txias-tiav.Cov hlau siv nyob rau hauv lub tshuab tubing tej zaum yuav cam khwb cia nyob rau hauv ingots los yog tej zaum yuav strand cam khwb cia.Thaum cov hlau sib txawv ntawm cov qib sib txawv yog ntu ntu ntu ntu, kev txheeb xyuas cov khoom hloov pauv yuav tsum tau ua.Seamless tubing yog cov khoom siv tubular ua tsis muaj vuam seam.Nws feem ntau yog tsim los ntawm cov hlau ua haujlwm kub, thiab yog tias tsim nyog, tom qab txias tiav cov khoom kub ua haujlwm tubular los tsim cov duab uas xav tau, qhov ntev thiab cov khoom.
Cov raj yuav tsum tau muab tso rau hauv cov duab hauv qab no: puag ncig, square, duab plaub thiab ntu tshwj xeeb.Kev ntsuas cua sov yuav tsum tau ua los txiav txim qhov feem pua ntawm cov ntsiab lus tau teev tseg.Yog siv cov txheej txheem melting theem nrab, cov kev ntsuas cua sov yuav tsum tau txais los ntawm ib qho remelted ingot los yog cov khoom ntawm ib qho remelted ingot ntawm txhua thawj yaj.Lub raj yuav tsum tau coated nrog ib zaj duab xis roj ua ntej shaping kom retard xeb thaum teev
