1. Cov ntsiab lus txhais thiab cov khoom siv ntawm AH-32 steel yeeb nkab
Ah {- 32 yog hom marine qauv hlau, ib lub siab-zog steel, ua rau cov koom haum thoob ntiaj teb ntawm cov txheej txheem kev sib tw (I SICS). Nws cov khoom tseem ceeb muaj xws li:
Cov ntsiab lus carbon tsawg dua los yog sib npaug rau 0.18%: Ua kom ntseeg tau Weldability thiab tsawg- kub nruj
Lw cov ntsiab lus (xws li MN, NB, thiab V) txhim kho lub zog thiab corrosion tsis kam
Paib lub zog ntau dua los yog sib npaug rau 315 MPa, tensile lub zog 440-590 mpa
Tsim tshwj xeeb rau cov nkoj nkoj thiab ua rau lub ntsej muag ua lag luam, nws tswj hwm tau zoo nyob rau hauv qis - qhov chaw ib puag ncig qis rau -20 degree.
2. Cov ntawv thov raug thiab kev lag luam zoo
Lub nkoj nkoj: Hull cov qauv, decks, bulkheads, thiab lwm yam load - cov kabmob sib xyaw
Offshore Platforms: Drilling Rigs, Tsho, thiab lwm yam xeb {{}}} tiv taus cov qauv
Cov Khoom Siv Hauv Qab Zib: Imerner Hulls, Cryogenic Cia Tso Tsheb Hlau Luam
Nco tseg: piv rau cov pa xa phaj phaj (xws li qib nyias nyias thiab qhov hnyav dua, txo qis} Qhov sib txawv ntawm cov roj av (piv txwv li, DH32)
Lub zog qib: Ah-32 muaj cov txiaj ntsig lub zog ntawm 315 MPa, qis dua DH32 (355 MPA).
Muaj feem kub: AH-32 yog qhov haum rau -20 degree, DH32 rau -40 degree.
Tus nqi - ua tau zoo: ah- 32 muaj peev xwm pheej yig thiab haum rau cov nkoj tsis-polar.
4. Cov ntsiab lus tseem ceeb rau kev ua thiab vuam
Cov txheej txheem vuam:
Tsawg - hydrogen mroundoadodes (piv txwv li E7018) pom zoo.
Preheating kub ntau dua los yog sib npaug rau 75℃(rau phaj tuab> 25 mm).
Txiav cov cai:
Qhov tawv txheej yuav tsum yog av tom qab ntshav lossis nplaim txiav.
Cov txwv txias los yog:
Dab tsi yog khoov radius yuav tsum yog ntau dua los yog sib npaug rau 3 zaug lub phaj tuab kom tsis txhob tawg.
5. Cov txheej txheem tseem ceeb rau cov pov thawj zoo
Cov ntawv pov thawj yuav tsum muaj: Yuav tsum muaj ntawv pov thawj los ntawm ib lub zej zog (piv txwv li, CCS, LR, thiab lwm yam).
Kev Kuaj Xyuas:
Charpy kev cuam tshuam lub zog loj dua los yog sib npaug rau 34 j ntawm -20℃(longitudinal quav).
Z - Axis Kev Kuaj (Txo thaj chaw ntau dua lossis sib npaug rau 35%).
Tsis - Kev sim:
Kev Kuaj Ultrasonic (thiab 60001) 10160 Txheej txheem)
Nto sib nqus partle kuaj (ISO 4987 txuj)
