Marine Pneumatic Ship Launching Airbag

Product Description

Marine Pneumatic Ship Launching Airbag
Marine Rubber Airbags The purpose of Marine rubber airbag is to make use of low-pressure air charging and large-area bearing function to complete the airbag discharging or launching operation on the ship.Taking advantage of the characteristics of low inflating pressure, large bearing area and easy rolling after large deformation of the airbag, the ship is first lifted from the pier with a lifting airbag, then placed on the rolling airbag, and then the ship is slowly moved into the water by towing the ship and the rolling airbag with steel cables.The diameter of the airbag is 0.8m-1m (lifting airbag is 2m), the length is close to the ship's width, the air pressure is 34kPa ~ 39kPa, and the maximum safety bearing capacity is 74kPa.The air bag is made of high strength fabric and rubber composite material, which is easy to repair when damaged.This method is simple and flexible, and can be applied to the launching area with different slope and soil quality. It has been used for launching small barge, tugboat and flat bottom boat with dead weight below 200T for some small inland river shipyards in China.
Marine launching airbag is an innovative product with independent intellectual property rights in China. Its application is less limited by site and does not require large mechanical equipment. Therefore, it can shorten the engineering cycle and save a lot of money.After more than 20 years of development practice, it has been proved that this product is safe and efficient, green and environmental protection, flexible and so on.At present, it has been widely used in heavy lifting and transportation, ship upstream and downstream, caisson lifting and transportation, other heavy lifting, underwater installation works to help buoy and other fields.
Maintenance of Marine Airbags
1. When the air bag is not in use for a long time, it should be washed and dried, filled with talcum powder and coated externally.
Airbag maintenance should be carried out in a dry, ventilated room away from the light source.
Airbags should be stored to avoid stretching, compression and deformation.
2. Keep the air bag away from heat source.
3. The air bag shall not be in contact with acids, bases, fats and organic solvents.
Repair of Marine Airbags
The damage forms of marine airbags can be generally divided into longitudinal cracks (cracks extending along the length of airbags), transverse cracks (cracks extending along the circumference), and nail holes (including disc-shaped damages with a diameter of less than 10 cm).
Marine Airbag Production Process:
1.Raw Material Preparation
2.Rolling Out for Airbag Body
3.Moulding two ends of the airbags
4.Air-inflation
5.Stretch-wrap, Integrated Cross Intertwine the Synthetic Cord Reinforced Rubber Layers
6. Vulcanizing
7.Fittings Assembling
8.Air-tightness Test
9.Surface Protection
10.QC Test as per GB/T3795-1996 and ISO 14409 International Standerd / Third-party Inspection
11.Packing & Delivery
