2. Manufacturing technology


The upper and lower launching of airbags for ships overcomes the drawbacks of being restricted by fixed launching slides when repairing and building ships, and has the advantages of low investment, flexible maneuverability, safety and reliability, and high comprehensive economic benefits. It is widely used in the drainage and launching of various types of ships, as well as salvaging sunken ships and moving heavy objects.
The structure of a new type of integrally wound marine high-strength airbag developed by "henger" is composed of two parts: a capsule body and an end iron part. The capsule wall is made of matrix rubber and reinforced fiber material through vulcanization, and the end iron part is made of metal material. The surrounding is tightly integrated with the bag body. One end is used for traction when carrying the air bag; the other end is used for inflation and deflation: connect the pressure gauge, inflation and deflation valve and inflation hose connector through the three-way connecting pipe. If the customer requires, the matching gas-filled pipe joints, pressure gauges and valves can be used as accessories: customers can also equip their own pipe accessories for connection.

Boat Launching Ship Airbag Marine Rubber Airbag 5-10 Layers 7


1. Air tightness test

Fill the air into the pneumatic lifting bags to a certain internal test pressure without any load. After one hour, measure the internal pressure again. By comparing with two times’ data, the pressure loss should be less than 5%.


2. Performance test

Without any load, fill the air into the airbag balloon by the airbag standard data form or by clients’ requirement.

We will do the strictly inspection before the delivery for the outer appearance and the air loose test. If it is unqualified, can not release definitely.


3. Blasting test

This test should give the minimum burst pressure value of the airbag, as listed in the airbag performance table burst pressure. In order to be safe, since the airbag belongs to the pressure vessel, it is necessary to use a water flushing while filling the airbag until the airbag bursts. The water pressure during airbag blasting should be larger than or equal to the values listed in the standard performance table.


4. Compression-recovery Test

In order to verify the recoverability of the airbag, the airbag should be repeatedly and rapidly compressed and released in a short time. Due to the limitation of the airbag length and the limitation of the compression recovery equipment, the compression recovery test can be reduced by the same number of layers. The airbag is inflated to make the internal pressure reach the pressure of the airbag performance data. And the airbag is vertically compressed until the compression deformation reaches 75%. Keep this state for 1 minute. The pressure is then released and the balloon diameter should be restored to more than 97% of its original diameter within 5 minutes.



Storage of the ship launching airbag


1. When we don’t use the marine airbag roller for a long time, it should be washed and dried. Should sue the external talcum powder on the lifting airbag surface. Should put the airbag in a dry, ventilated room away from the light source. Keep away the shipping airbags safe to avoid stretching, compression and deformation.

2. Keep the airbag away from heat sources.

3. Can not contact the airbags launching to acids, alkalis, greases and organic solvents.

4. When the airbag ship is not in use, we should keep it in the status of stretched flat, not stacked, and no heavy objects piled on it


Notice during the use of the ship balloon:

1. While the shipping air launching airbags are in use, strictly control the pressure, prohibit use of exceeding the work pressure.


  • The surface in contact with the shipping lifting airbag must not have a sharp protruding hard object to prevent the airbag skin from being pierced.


  • Try to avoid distortion in the length of the airbag.
  • Should avoid the inflatable load after we have in charged the air into the airbag.
  • For example, when the ship is erected, when the lifting airbag has lifted most of the hull, remove most of the pier and fill the rolling airbag. If there are 1-2 piers still under compression, the internal pressure between the airbags should be adjusted so that the ship can be removed from the side of the ship. And the pier can not be manually used. Otherwise, the ship may be forced to impact the airbag that has been filled.
  • Another example is the collision with other objects for various reasons during the ship transfer process. In severe cases, the impact airbag may be damaged.
  • Before long time no use or re-use after repair, we should carry out the air filling test again. The air internal pressure should be the same as the factory test value of our factory. The test worker should keep away three meters from the airbag during the test. If the airbag repaired by a large area damage, we should decrease the use pressure. Therefore, for the airbag often used, still need the above test once a year.
  • Do not drag the ship launch airbag on the hard ground.
