Product Description   Rubber Airbag Introduction: Rubber Airbags, basic body consists of rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable in to roll.     Rubber Airbag Parameter:  ( we can supply detailed dimension )
 

Diameter (D):	From 0.5m to 2.8m
Effective Length (EL):	From 5.0m to 24.0m
Total Length (TL):	From 6.0m to 25.5m
Standard Number of Layers:	Usually 4-10 layers
Loading Capacity:	About 10-40 T/M

 
Rubber Airbag Advantages: Different airbag size stock available, quick delivery Provide repair kit and on site instruction Long time service life can be reused many times Wear resistance and anti aging Good raw material and cord fabric Do no harm to the environment. Time & money saving Need no more than air compressors, winches and ropes Marine Airbags are much cheaper and portable than other methods   Rubber Airbag Materials: An airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. The arrangement of synthetic-tyre-cord reinforcement layers is shown in the picture below, all materials shall be vulcanized firmly.     Prior to the airbag production, the outer and inner rubber layers shall be tested to meet criteria in the following table in accordance with the test methods given in the international standard list in the table. While only one satisfactory sample per batch is required for test numbers 1 through 3, all Others must be tested for test numbers 4 through 9 annually. If the first sample fails, two additional sample should be tested. If the additional samples pass the test requirements, the materials will be deemed to have passed the test. Otherwise, the materials will be deemed to have failed the test and another batch of materials shall be selected.     Rubber Airbag Specification: Rubber Airbag Test: Unless otherwise specified, test shall be performed under the following conditions: ambient temperature 10-35. Media: dry clean compressed air, and clean fresh water for bursting test. The test should be performed using a full sized airbag. If the airbag is too large to be mounted on the test machine, they test may be performed on a scaled-down airbag. In order to maintain a proper representation of the full-size sample airbag, the diameter of the scaled-down airbag shall be no less than 1/2 of the full sized sample airbag diameter, while the length shall be no less than 3 times the diameter of the scaled-down airbag.   Gas-tightness test Without carrying any load, fill the airbag till the internal pressure of the airbag in the following tale. The internal pressure should be recorded and compared with the pressure after 1 hour. The pressure loss should be less than 5% of pressure.     Rubber Airbag Application: 1.For ship upgrading, conversion or new/repair launching (Ship launching airbags)
2.Marine Airbag for salvaging sunken ship or heavy immersed steel structure
3.For hoisting and transporting heavy goods up to 10,000 tonnes structure on land
4.Marine Pneumatic Rubber Fender for protective purposes, ships collision avoidance
5.Pneumatic rubber core for architecture engineerinContainer for storing and transporting gas and corrosive chemical liquid and pure water for voyage
6.Rubber bag for ship ballast   Rubber Airbag Safety & Storage: Rubber Airbags Safety precaution: Over pressure Control: Strictly control the operating pressure, over pressure is forbidden. The Landing Slipway Requirements: The landing ground should be ground or cement concrete, according the tonnage of different ships. Avoid Sharp Objects: Make sure no sharp objects and make sure the smooth and clean ground during using them in case of break of airbag. Avoid Distortion And Overweight Avoid distortion in the length direction during rolling and avoid overweight load after gas charging.   Rubber Airbags Storage: The airbags should be maintained in a dry ventilated room and be protected from light.  The airbags should be in a relaxed condition free from tension, compression or other deformation. The airbags should be kept away from any heat source. The airbags should be protected from acids, alkalis, oils or organic solvents.
