Marine Launching Air Bag is a kind of flexible heavy weight carrier which is designed on the principle of rolling wood. This air bag producing by integral winding is more reasonable in structure, and has higher safety factor and bearing capacity. The product is alsocharacterized by safety, high efficiency, environmental protection and flexibility.
The Marine Launching Air Bag products are mainly used in the fields of ship loading and unloading, lifting and handling of heavy objects, underwater installation and buoyancy support.
Marine launching air bags consist of three parts:
1.Air bag body: the main cylindrical part of the air bag, fully inflated with compressed air.
2.Air bag heads: conical parts connecting the body and the mouths of the air bag.
3.Air bag mouths: either metal valves mounted on both ends of the air bag for inflating with air or a valve on one end and a metal lug on the other end used to haul the air bag.
Marine launching air bags are constructed of synthetic-tire-cord layers; inner and outer rubber layers are sometimes added. All materials used are vulcanized.
Air tightness test: Without carrying any load, fill the air bag till the internal pressure of the air bag reaches rated working pressure. After 1 hour. The pressure loss should be less than 5 % of initial pressure.
Bursting test: Fill the air bag with water until the air bag bursts. The water pressure at the time of bursting shall be no less than three times of rated working pressure.
