Marine airbag is an innovative product with independent intellectual property rights in my country. After more than 20 years of development and practice, it has been proved that this product has the characteristics of safety, high efficiency, green environmental protection, flexibility and so on. Removal, wreck salvage, buoyancy aid for underwater installation projects, etc. The application of marine airbags is limited by the site and does not require large-scale mechanical equipment. Therefore, it can shorten the engineering cycle and save a lot of money. It is very popular with domestic and foreign shipyards, salvage companies, large building component factories and other users.

The integrally wound marine airbag is composed of two parts: the mouthpiece and the body (conical body and cylindrical body). The mouth of the bag is made of Q235 hot-dip galvanized, which has good seawater corrosion resistance. The conical bag body wraps the bag mouth, and forms a whole with the cylindrical bag body through the seamless winding process, which ensures the sealing performance, bearing capacity and safety of the air bag.

The skeleton material of the airbag is made of nylon cord fabric used in the production of automobile tires. The inner layer of the airbag has a rubber layer with good air tightness, which is used to seal the compressed gas when the airbag body is subjected to high pressure, and the outer layer has a rubber layer with high wear resistance, flex resistance, corrosion resistance and aging resistance. Therefore, various properties such as tear resistance, tensile strength, and service life of the airbag have been greatly improved during use.

High-strength and durable marine airbags
​The upper row and launching of airbags for ships is a promising new technology. It overcomes the drawbacks that the ship repair and building capabilities of small and medium-sized shipyards were limited by fixed launching slides in the past, and has developed into today's flexible and flexible launching technology. It has the advantages of labor saving, time saving, labor saving, investment saving, flexibility, safety and reliability, and significant comprehensive economic benefits.

The Changlin brand ship launching air bag is composed of three parts: the end iron piece, the conical end bag body, and the cylindrical bag body. intensity of pressure.

The pipe threads of the iron pieces at both ends of the airbag are the same, which can be used to connect the sealing ring, and also can be used to connect the accessories of the inflation pipeline.

Standard sizes

The standard specifications of the airbag diameter D produced by our company are 0.8m, 1.0m, 1.2m, 1.5m, 1.8m, 2.0m, 2.5m, etc. Users who need special specifications can put forward when ordering. The airbag length L is based on the user Order confirmed.

Model

According to the bearing capacity of the air bag per meter length, the air bag can be divided into two categories: QP-normal air bag; QG-high bearing capacity air bag.

According to the classification method of ship airbags stipulated in the international standard ISO14409:2011 "Ship and Maritime Technology-Ship Launching Airbags", the original product models of the ship launching airbags produced by our company are compared with the international standard models as shown in Table 1, of which QP4 and QP5 are common bearing Airbags with high load-bearing capacity, QG6, QG7 are high-capacity airbags.
