CCS Vessel Airbag for Ship Landing

Introduction
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 aseasy to operate, timesaving, saving investmentsafety, etc.

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.
Major Strengths of Vessel Airbag:Long lifespan: It is guaranteed that our airbags can sustain their designed operating pressure for 3 years.

Note:1. Rated working pressure:±5%.
2. Compress deformation: ±2%.
3. Bearing capacity: one meter airbag at a deformation rate of 70%, internal pressure equivalent to the rated pressure value of Pe.8. Material: A ship lunching airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. All material layers should be vulcanized firmly.
