Qhov sib txawv tseem ceeb ntawm ASTM A213 thiab A269 yog cov khoom sib txawv thiab kev siv lawv siv tau. cov
Qhov sib txawv tseem ceeb ntawm ASTM A213 thiab A269 yog cov khoom sib txawv thiab siv tau rau. cov
ASTM A213 : Cov qauv no tsuas yog siv los tsim cov khoom siv turbine, cov khoom siv dav hlau, cov khoom siv hluav taws xob, thiab ntau yam khoom ua haujlwm txias, thiab lwm yam. Nws npog seamless thiab welded austenitic stainless hlau kav.
Cov khoom lag luam rau A213 tus qauv feem ntau yuav tsum tau ua haujlwm txias thiab tsim nyog rau cov sijhawm uas cov khoom siv siab thiab corrosion kuj yuav tsum tau.
ASTM A269 : Hauv qhov sib piv, A269 tus qauv tsim nyog rau ntau yam kev siv, suav nrog kev pabcuam dav dav. Nws npog seamless thiab welded austenitic stainless hlau kav, tsis txwv rau cov khoom ua haujlwm txias. A269 muaj cov qauv qis dua li A213 thiab tsim nyog rau kev tsim cov khoom lag luam uas tsis tas yuav ua haujlwm txias, xws li cov kav dej, cov khoom siv kho mob, thiab cov hlab ntsha siab. cov
Nyob rau hauv luv luv, ASTM A213 yog tsuas yog siv los tsim cov khoom uas yuav tsum tau muaj zog thiab corrosion kuj, xws li dav hlau thiab tshav kub exchanger Cheebtsam, thaum ASTM A269 yog haum rau kev tsim cov khoom siv dav dav, xws li cov kav dej thiab cov hlab ntsha siab.
GNEE tuaj yeem muab cov kav dej ua ntej nrog txoj kab uas hla ntawm DN15 (1/2 ") mus rau DN3000 (120"), phab ntsa tuab qib SCH5S rau SCH160, thiab cov ntaub ntawv npog ntau qib: carbon steel, stainless hlau, duplex stainless hlau / super duplex steel, Nickel-based alloys, titanium alloys, thiab lwm yam.
Cov txheej txheem tsim khoom tuaj yeem tsim ua raws li cov qauv tsim xws li GB, HG, SH, SY, DL, ISO, ANSI / ASME, MSS, JIS, EN, AS, thiab lwm yam, thiab cov khoom tsim kho kuj tuaj yeem muab raws li cov neeg siv khoom. kos duab kom tau raws li qhov xav tau ntawm kev lag luam sib txawv thiab cov qauv sib txawv.
