Seamless kav rau nkoj

Ntxiv nrog rau cov khoom siv tshwj xeeb, cov kav dej seamless rau cov nkoj yuav tsum tau ua kom zoo nkauj sab hauv thiab sab nrauv, me me sab nrauv (sab hauv) txoj kab uas hla, thiab cov phab ntsa tuab. The characteristics include dense metallographic structure, good mechanical properties, resistance to seawater corrosion, and long service life. Lub tuam txhab muaj ntawv pov thawj Hoobkas los ntawm kev faib cov koom haum xws li ABS hauv Tebchaws Meskas, BV hauv Fabkis, DNV hauv Norway, RS hauv Russia, CCS hauv Suav teb, nrog rau ASME cov ntaub ntawv pov thawj
Main txheej txheem txheej txheem:
1. Xaiv (Baosteel, Taiyuan Hlau thiab Hlau, Yongxing) siab - zoo forged, nruam nruam thiab perforated khoom
2. Kev tshuaj xyuas cov yeeb nkab, tshuaj ntxuav kua qaub, polishing, txias dov / rub
3. Degreasing, solidification, acid ntxuav
4. Degreasing, solidification, acid pickling thiab passivation NDT, Dej siab, huab cua nruj kev ntsuam xyuas, siv lead ua corrosion test, kub kub, kuaj lub cev thiab tshuaj.
