Steel Qib thiab Daim Ntawv Thov
ASTM A335 P91 yog ib qho ntawm cov qib siv dav tshaj plaws ntawm cov yeeb nkab steel vim nws qhov kev sib xyaw ua ke zoo heev ntawm lub zog kub, kev tiv thaiv corrosion, thiab fabricability. Nws yog feem ntau siv hauv cov ntawv thov xws li:
Fais fab nroj tsuag:ASTM A335 P91 cov kav dej tau siv dav hauv kev tsim cov boilers, superheaters, thiab kub exchangers nyob rau hauv lub fais fab nroj tsuag. Lub zog kub-kub ua rau nws tsim nyog rau cov kav dej thiab lwm yam khoom siv uas ua rau muaj kev kub ntxhov thiab kub kub.
Refineries:Hauv kev lag luam roj thiab roj, ASTM A335 P91 kav dej pom cov ntawv thov hauv cov refineries, tshwj xeeb tshaj yog nyob rau hauv high-temperature cracking units thiab distillation txhua.
Petrochemical cog:Cov yeeb nkab steel hlau yog siv rau hauv ntau yam txheej txheem hauv cov nroj tsuag petrochemical, xws li hauv qhov cub tawg, catalytic cracking units, thiab kub-kub tshuaj reactors.
Kev Pabcuam Kub Kub:Sib nrug los ntawm cov kev lag luam tshwj xeeb uas tau hais los saum toj no, ASTM A335 P91 cov kav dej yog siv rau hauv ib qho txheej txheem lossis daim ntawv thov uas muaj qhov kub thiab txias ib puag ncig.
