Ship launching airbags are to be constructed of a cylindrical body and two conical heads (one at each end). Ship launching airbags with lots of advantages, such as easy to operate, time saving, saving investment safety, etc.
Major Strengths of Ship Launching Airbags:
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.
Good air tightness: Pressure decreases less than 10% for a period of 24 hours.
Long lifespan: It is guaranteed that our airbags can sustain their designed operating pressure for 3 years.
