1. Dab tsi yog ATTM A131 AH32 AH32 AH32 AH32 AH32, thiab nws txawv li cas ntawm cov qauv hlau zoo tib yam?
Teb:
ASTM A131 AH32 yog aHigh-zog Hull Txheej Txheem Qauv Hlaumuaj ntawv pov thawj rau kev siv marine, featuring:
Paib lub zog ntau dua los yog sib npaug rau 315 MPa(vs . 235 mpa mpa kom cov hlau me li A36).
Txhim kho corrosion tsis kamNrog tswj Cu, ni, thiab zawj.
ABS / DNV / GL / LR Multi-Soci-Socior(Tsis zoo li cov hlau ib leeg).
Kev cuam tshuam-kuaj ntawm -20 degree(Raws li IMO Polar code rau cov nkoj tsis-arctic).
2. AH32 nyob qhov twg yog AH32 feem ntau thov hauv nkoj kev tsim kho?
Teb:Cov Kev Siv Cov Ntaub Ntawv Feem Ntau:
Lub ntsiab hull cov qauv(Lawj daim hlau, bulkheads).
Ballast Tso Tsheb Hlau(corrosion-resistant tsim).
Mid-nkoj ntu(cov chaw ntxhov siab ntau).
Roj Tanker Cargo Hneev(Hic-resistant variants muaj).
3. Yuav ua li cas lawd ah32 sib txawv ntawm vuam me hlau?
Teb:Cov kev txiav txim siab vuam:
Preheat:50-125 Qib (nyob ntawm cov tuab).
Cov tub lim hlau:AWS E7018 rau smaw, ER70s-6 rau GMAW.
Cov tswv yim tshav kub:Txwv rau 35 kj / cm kom tsis txhob muaj kev muag khoom zoo.
Kev kuaj xyuas tom qab Weld:Yuav tsum MPI rau cov pob qij txha tseem ceeb.
