This product is a high strength weaved airbag with spiral wound developed by our company Its structure includes two parts the body of airbag and iron pars. The rubber layers made of natural rubber, elastic fiber, and some other special materials. The head space by metallic material, it integrated with the airbag body. The pressure of spiral wound is completed.
The airbag body is combined by two parts the inner layer bag and cord tire. The inner layer is made separately and the cord tire is wound crossly from both heads. We inspect air leak points by through 5 steps during the whole producing process, strictly ensure the gas tightness. High strength, flexible cord increased the traits of against high pressure explosion resistance. The product is produced in inflated state from beginning to end.

Special Attentions During Use and Launching of The Airbag
First, the airbag must be checked if the pressure gage is normal before being used.
Second, the working pressure of the airbag when used should compare the data in the bearing pressure capacity from mustn’t use excessive pressure.
Third, it must clean the sharp and protruding hard object on the ground which could contact with the airbag body before the airbag being used, in case it punctures the skin of the airbag.
Forth, the distance of the airbag under the ship should no less than 1.5 meters, the distance after compression should at least 0.8 meters, in case occurs the airbag over lapping phenomenon when the ship launching.
Fifth, lifting after the airbag be forced under the ship, when most of the ship is raised up, demount the pier-top and force the rolling airbag at the same time, if there is one or two pier-top impacted which is difficult to take out, do not let the workers force to demount the pier-top, if the pier-top is demount, it is easy to suffer from the ship gravity, and then will make the airbag the airbag explosive. The workers should check the working pressure of the airbag if could be increased.
, if the air-bag have used for alone time, it should be inflated pressing inspection, according to the .the pressure should take 1.25times of the working pressure, so that could make sure safety use of the airbag. read more...
