ASTM A312 yog ib qho kev lees paub dav dav thiab kev saib xyuas tshwj xeeb tsim los ntawm American Society for Testing and Materials (ASTM). Nws tshwj xeeb yog hais txog seamless thiab welded austenitic stainless hlau kav, uas yog feem ntau siv nyob rau hauv ntau yam industries rau conveying kua thiab gases nyob rau hauv ib tug ntau yam ntawm kev siv. Cov kav dej no paub txog lawv cov kev tiv thaiv corrosion zoo heev, ua rau lawv zoo tagnrho rau kev siv hauv qhov chaw corrosive.
ASTM A312 specification npog ntau yam stainless hlau qib thiab qhov ntau thiab tsawg, txhua tus tsim los ua kom tau raws li cov kev cai tshwj xeeb rau kev siv sib txawv. Qhov kev ua tau zoo no ua rau nws muaj kev xaiv zoo tshaj plaws hauv kev lag luam xws li kev lag luam tshuaj, tshuaj, khoom noj thiab dej haus, petrochemicals, thiab lwm yam.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm A312 cov kav dej yog lawv lub peev xwm tiv taus qhov kub thiab txias siab, ua rau lawv tsim nyog rau ob qho tib si kub siab thiab cov kev pabcuam cryogenic. Tsis tas li ntawd, A312 cov kav dej tuaj yeem tsim tau ob qho tib si seamless thiab welded cov ntaub ntawv, muab kev yooj yim hauv kev tsim thiab kev teeb tsa.
Txhawm rau kom ntseeg tau qhov zoo thiab kev ntseeg siab ntawm A312 cov kav dej, cov lus qhia tshwj xeeb suav nrog cov txheej txheem kev sim nruj xws li kev sim hydrostatic, kev sim tsis muaj kev puas tsuaj, thiab kev sim tshuab. Qhov no tau lees tias cov kav dej ua tau raws li cov qauv tsim nyog rau kev siab, kub, thiab corrosion kuj.
Hauv cov ntsiab lus, ASTM A312 plays lub luag haujlwm tseem ceeb hauv kev muab cov kav hlau stainless uas ua tau raws li qhov xav tau ntawm kev lag luam uas muaj kev tiv thaiv corrosion, lub zog, thiab kev ntseeg siab yog qhov tseem ceeb. Cov kav dej no yog cov khoom tseem ceeb hauv kev siv suav tsis txheeb uas tso siab rau kev nyab xeeb thiab kev thauj mus los ntawm cov kua thiab roj.
