Yacht Inflatable Marine Rubber Airbag For Ship Launching In Maldives

Marine rubber airbags are also known as air bladders,ship lifting airbag,ship rubber airbags,rubber tube,ship salvage airbags,rubber pontoon,inflatable air bags,air lifting bags,air ballon,salvage bags,ship launching rubber airbag.Airbags now are used for ship launching ,loading and floating,they are widely used in cargo/boat /ship/vessel lauching and landing,lifting and moving sunken ships and heavy goods.

The bearing capacity of marine airbags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.
Because of the flexibility of marine airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of airbags will vary as well as the contact area.
The approximate bearing capacity can be calculated as follows:
F=PS S=π x (D1-D2)/2
Mark:
F: Bearing capacity
P: Inner pressure
S: Contact area
D1: Diameter of airbags when free of loat
D2: Working height of airbags when loaded

Step1: Prepare the launching slipway and related workers. As per calculation, select and check the appropriate marine airbags and quantity. Tidy up the launching slipway. Fix the ship by winch and anchors. Prepare all the necessary equipments.
Step2: Taking out all standing blocks under stern and middle one by one, and put in airbags. The distance between two rows should be confirmed as per the calculation.
Step3: Taking out all standing blocks under the prow. Run the winch and release the cable. Let the ship launch to water.
Step4: After launching, check all the deckhouse to confirm if there is any problem. Meanwhile, retrieving all the airbags.

1.The airbags must be checked if the pressure gage is normal before used.
2.The working pressure of the airbag whenused should compare the data in the bearing oressrre capacity from mustn't use excessive pressure.
3.It must clean the sharp and protruding hard objects on the ground which could contact with the airbag body before the airbag being used, in case it punchures the skin of the airbag.
4.The distance of the airbag under the ship should no less than 1.5m,the distance after compression should at least 0.8m, in case it occours the airbag overlapping phenomenon when the ship launching.
5.Lifting after the airbag be forced under the snip, 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 works force todemount the pier-top,if the pier-top is demounted, it is easy to suffer from the slip gravity, and then will make the airbag explosive. The workers should check the working pressure of the airbag.

1. High strength: The polyamide cord thread for airbag is produced with high tension reinforced fiber. A cord thread has the strength more than 32N, and the cord fabric has consistent and reliable quality.

2. Wear resistance and anti-aging: An airbag often works in extreme conditions.For example, it is soaked in sea water, insolated in the direct sunlight and rolled in sand. Our marine airbag has high wear resistance and anti-aging ability, and the service life as long as 8-10 years.

3. Good air tightness: Our factory use high quality natural rubber and advanced manufacture process to assure that our products have good air tightness.

4. Safety and reliability: Shenxing marine airbag has the safety coefficient of 4-6 times, means that its bursting pressure is 4-6 times its work pressure.
