Kev faib tawm los ntawm kev tsim khoom
347h Seamless Steel Kavyog tsim los ntawm tho cov blanks thiab tom qab ntawd txias kos duab lossis cov dov txias, tsis muaj ob sab. Cov txheej txheem tsim qauv no muab lawv cov khoom siv sib tsoo tsis zoo, ua rau lawv tiv thaiv lawv cov tshuab sib cav.
Yog li ntawd, cov kav dej seamless tshwj xeeb yog tsim nyog rau qhov tseem ceeb high {{{{{{{{{{{{{{{} kub} kub remotines hauv kev lag luam petrochemical.
The disadvantages are relatively high production costs, and the technical difficulty in producing large-diameter, ultra-thin-walled pipes, with the risk of cold-drawing fracture.
347H Welded Steel Kavyog tsim los ntawm dov thiab vuam TPE47H steel phiaj lossis cov strips siv ntau txoj kev vuam txoj kev vuam. Welded kav muaj ntau dua ntau lawm, tus nqi qis dua, thiab tuaj yeem tsim loj- txoj hauj lwm uas hla.
Cov kev vuam vuam suav nrog tus tsov, thiab siab {- zaus ua haujlwm siv rau kev tsim khoom siv ua tiav raj kav.
Cov no yog feem ntau siv hauv kev hloov pauv cua sov, cov hws, qee cov khoom siv uas tsis pom zoo thiab qhov ntsuas kub tsis yog txoj kev nruj heev.
Kev faib tawm los ntawm cov khoom lag luam
Tp347h leegYog cov khoom lag luam tshwj xeeb ua tiav, nce lawv qhov chaw sab nraud los ntawm kev siv vuam kom zoo lossis ntev ntev rau sab nraud ntawm lub raj.
Qhov tsim qauv no tau txhim kho kev ua kom sov kub. Vim yog lawv qhov siab heev - kub lub zog, cov roj ua ntej, thiab ntau yam siab kub- kev hloov pauv hluav taws xob.
Nrog kev tu kom tsim nyog, cov leeg tau zoo no muaj kev tsim lub neej ntawm ntau tshaj 20 xyoo.
347h lub raj dawbNrog tus sab hauv thiab sab nraud phab ntsa, yog cov ntawv siv dav tshaj plaws. Lawv tau muab rau hauv cov qauv ntau thiab tsawg dua thiab tuaj yeem raug kho rau cov neeg siv khoom, suav nrog cov doorers tshwj xeeb, thiab txiav kom ntev.
