CCS Vessel Airbag for Ship Landing
Vessel Airbag are to be constructed of a cylindrical body and two conical heads (one at each end).  Vessel Airbag with lots of advantages, such as easy to operate, time saving, saving investment safety, etc.
    Â
          Â
Good air tightness: Pressure decreases less than 10% for a period of 24 hours.
High level of safety: Equipped with a reliable safety valve, our airbags can stand the maximum pressure up to 4 times that of the operating pressure.
