A691 steel yeeb nkab ua raws li American Society for Materials standard ASTM A691 thiab feem ntau yog siv nyob rau hauv high-temperature ib puag ncig nrog high-pressure kev pab cuam, xws li roj thiab roj extraction, tshuaj ua, thiab tsheb thauj mus los.
A691 steel yeeb nkab yog tsim los nrog cov qauv nruj dua los xyuas kom meej nws qhov zoo thiab kev ntseeg tau, thiab nws lub zog thiab kev ua neej zoo dua rau ntau lwm hom welded kav.
Qhov zoo ntawm A691 steel yeeb nkab
Kev ua tau zoo ntawm qhov kub thiab txias: A691 steel kav tuaj yeem tiv taus kev ua haujlwm hauv qhov chaw kub kub, tswj kev ruaj ntseg, thiab tsis yooj yim deformed lossis melted. Lawv tsim nyog rau cov txheej txheem kub ntawm cov kav dej.
Muaj zog corrosion kuj: Hauv corrosive media xws li acids thiab alkalis, A691 steel kav ua tau zoo, tsis yooj yim puas, thiab muaj lub neej ntev kev pab cuam.
Lub zog zoo: A691 steel yeeb nkab muaj lub zog siab thiab kev ua haujlwm siab zoo, thiab tsim nyog rau lub sijhawm uas hnyav dua.
Kev ua tau zoo: A691 steel yeeb nkab yog ib qho yooj yim rau kev ua ntau yam duab kom tau raws li qhov xav tau ntawm engineering sib txawv thiab tau siv dav hauv ntau yam lag luam.
