ASTM A213 yog cov qauv kev ua haujlwm los ntawm ASTM thoob ntiaj teb uas npog Seamless Ferritic thiab Austenitic alloy {{{2} {2} {2} - kev sib pauv tub. Cov kav dej no tau tsim tshwj xeeb rau kev pabcuam hauv high- kub thiab siab} Cov khoom tseem ceeb hauv kev siv cov ntawv thov kev lag luam.
Thawj qhov kev sib txawv ntawm Astm A213 yog lawv ** Seamless entrial siv **. Tsim los ntawm cov txheej txheem zoo li extrusion lossis tho ib lub nplua nuj nqi, lawv tsis muaj lub ntsej muag welded. Qhov no xav tau tus yam ntxwv zoo tshaj, muaj kev sib luag, thiab kev ntseeg tau kev pheej hmoo, txo qhov kev pheej hmoo ntawm tsis ua haujlwm.
Tus qauv encompasses ntau cov qib alloy, txhua qhov tsim nrog cov tshuaj lom neeg tshwj xeeb kom ua tiav cov khoom xav tau. Cov lus Ferritic (MARENENITITIC) suav nrog ** T5, T9, T9, T91, thiab T91 **, uas muaj lub zog zoo ntawm kev kub siab. Austenitic stainless me me me, xws li ** TPP36L, TPP36, Tp321 **, tau teev rau lawv cov kev ua kom zoo dua thiab muaj zog siab.
** Cov yam ntxwv tseem ceeb thiab xav tau ntawm Astm A213 kav suav nrog: **
* ** High {{- kub ua tau zoo: ** Lawv yog tus tsim tawm kom muaj kev ntseeg siab (ntxhov siab rau kev kub ntxhov ntau tshaj li 1000 ° F (540 ° C).
* ** Qog thiab oxidation tsis kam: ** Cov alloying tseem ceeb xws li chromium thiab npib tsib xee kom muaj kev ntsuas pom hauv cov roj hmab thiab cov txheej txheem tshuaj lom neeg.
* ** Kev tswj nruj nruj: ** Tus qauv tsim nyog ua nruj, suav nrog kev ntsuam xyuas hluav taws xob, kev ntsuas hluav taws xob, kev ntsuas tshuaj tsw qab, thiab cov tshuaj tua hluavtaws kom nruj thiab zoo.
Raws li qhov tshwm sim ntawm cov hlua khi no, astm A213 Seamless Tubes yog cov khoom siv xaiv nyob rau hauv cov ntawv thov tseem ceeb xws li:
* ** Fossil Roj thiab Nuclear Fais Fab Cog Boilers thiab Superheaters **
* ** Kev hloov kho kom sov thiab cov hws hauv kev lag luam petrochemical **
* ** Txheej txheem tubing hauv ntau yam cua kub 4 **
Hauv cov ntsiab lus, Astm A213 sawv cev rau chav kawm ntawm siab-}}} Kev ua tau zoo seamless thiab ua tau zoo sib xyaw thiab cov txheej txheem ua kua dej nyob rau hauv cov kev pabcuam hnyav. Nws cov dej {{- Txhais cov khoom siv zoo, thiab cov qauv kho tshuab ua rau muaj kev ntseeg siab thiab kev ntseeg siab rau kev siv hluav taws xob tseem ceeb.
