ASTM A312 TP304 yog dab tsi?
Thaum sib txuas lus nrog cov neeg xa khoom muaj peev xwm 304 ss tubing, "ASTM A312 TP304" yog lub ntsiab lus tseem ceeb kom nkag siab. Nws tsis yog ib qho khoom tsim tawm xwb - nws yog kev cog lus rau qhov zoo.
Cias muab, ASTM A312 yog tus txheej txheem thoob ntiaj teb qhia txog seamless thiab welded austenitic stainless hlau nominal kav. TP304 tshwj xeeb qhia txog qib 304 stainless hlau. Thaum koj tus neeg muag khoom thov kev ua raws li tus qauv no, nws txhais tau hais tias cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, kev sim hydrostatic, thiab qhov ntev ntev tau dhau los ua pov thawj nruj heev - ua rau nws tsim nyog tshwj xeeb rau cov kav dej uas thauj cov kua dej. Nkag siab qhov no ua lub hauv paus rau kev sib tham nrog cov neeg muab khoom.
ASTM code rau 304 stainless hlau yeeb nkab yog dab tsi?
Lo lus nug no tseem ceeb heev vim tias nws qhia txog qhov sib txawv tseem ceeb: "Pib" thiab "Tubing" muaj cov ntawv thov sib txawv.
Raws li tau hais los saum toj no, ASTM A312 TP304 feem ntau tswj hwm "Pib" siv hauv cov kav dej.
Rau "Tubing" siv nyob rau hauv cov khoom xws li boilers thiab tshav kub exchangers, feem ntau tus qauv yog ASTM A213 TP304. Tus qauv no tsim cov kev cai nruj dua ntawm cov khoom siv hauv kev ua haujlwm siab - qhov kub thiab txias.
Ib tus neeg muag khoom raws caij nyoog yuav tsis thov rau "304 tubing." Hloov chaw, lawv yuav delve rau hauv koj daim ntawv thov tshwj xeeb rau kev tsim qauv, kev xa dej, lossis kev sib pauv cua sov? Raws li qhov kawg -siv, lawv yuav pom zoo kom ua raws li qhov zoo tshaj plaws thiab tus nqi- daws teeb meem. Qib kev txawj ntse no yog lub cim ntawm tus neeg muab khoom tshwj xeeb.
