Daim ntawv thov

 

Cov qib steel no feem ntau yog siv hauv cov hauv qab no:

 

Hull Kev Tsim Kho: Lawv tau siv dav hauv kev tsim cov nkoj hulls, muab lub zog tsim nyog thiab ua haujlwm kom tiv taus qhov hnyav marine ib puag ncig thiab ntau yam kev thauj khoom thaum lub sijhawm ua haujlwm ntawm lub nkoj.

Offshore Platforms: Nyob rau hauv kev tsim kho ntawm ntug dej hiav txwv platforms, cov hlau daim hlau no yog siv los tsim cov qauv tsim, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov platforms hauv dej hiav txwv.

Submarine Pipelines: Lawv kuj tsim nyog rau kev tsim cov kav dej hauv qab dej, uas yuav tsum muaj cov khoom siv nrog cov khoom zoo corrosion thiab cov khoom siv thauj khoom thauj roj, roj, thiab lwm yam khoom hauv qab hiav txwv.
