Qib Steel
JIS G3464 txhais ntau qib steel uas ua raws li cov tshuaj muaj pes tsawg leeg thiab cov cuab yeej cuab tam. Cov qib no xyuas kom meej tias cov hlau yob tuaj yeem ua tau zoo nyob rau hauv qhov sib txawv siab thiab kub. Qee cov qib steel muaj xws li:
SIB 380: Qib no qhia tau zoo heev ntawm qhov kub thiab txias thiab tsim nyog rau cov ntawv thov uas xav tau kev ua tau zoo hauv kev siab siab.
SIB 450: Nrog lub zog tensile ntau dua thiab tawm los, qib no yog qhov zoo tagnrho rau cov ntawv thov uas xav tau ntau dua thiab qhov kub thiab txias.
TIAB SA 690: Muab lub zog tensile siab tshaj plaws thiab tawm los ntawm cov qib, STBL 690 yog siv rau qhov chaw siab tshaj plaws.
Daim ntawv thov ntawm JIS G3464 Rolled Steel Tubes
JIS G3464 dov steel raj pom cov ntawv thov hauv ntau qhov kev lag luam uas muaj qhov kub thiab txias siab. Qee cov ntawv thov tseem ceeb suav nrog:
Boilers: Cov raj feem ntau yog siv rau hauv boiler systems, qhov chaw uas lawv ua hauj lwm raws li lub tshav kub exchangers, nqa kub gases thiab chav.
Thaum tshav kub kub Exchangers: JIS G3464 hlab ua kom yooj yim hloov cov cua sov hauv cov khoom siv hluav taws xob hauv cov txheej txheem kev lag luam.
Lub zog tiam: Cov raj no yog cov khoom siv tseem ceeb hauv cov chaw tsim hluav taws xob, pab thauj cov pa ntawm kev kub ntxhov kom tsav turbines.
