What affects the performance of ship launching airbags?
The launching of vessel is a verification of the vessel’s safety performance and construction quality. Successful launching also marks the beginning of the vessel’s life cycle.
In recent years, in addition to several traditional ship launching methods, marine airbags have attracted much attention as a more flexible and affordable method of launching ships. At the same time, in order to ensure the safety of ship launching, the quality and performance of marine airbag are particularly important.
So what affects the performance of ship launching airbags?
Actually, the performance of ship launching airbag is closely related to its layers and diameter. The layers and diameter of the airbag are different , then the compression performance of the airbag is also different, here simply share with you the different performance corresponding to the following conventional size airbag.
Number of layers | Diameter(m) | Rated Pressure | Bearing capacity per meter (at 70% deformation and rated pressure) (Kn/m) | Min. bursting pressure (kpa) |
4 | 1.0 | 130 | 143 | 390 |
| 1.2 | 110 | 145 | 330 | |
| 1.5 | 90 | 148 | 270 | |
| 1.8 | 80 | 158 | 240 | |
| 2.0 | 70 | 154 | 210 | |
| 5 | 1.0 | 170 | 186 | 510 |
| 1.2 | 140 | 185 | 420 | |
| 1.5 | 110 | 181 | 330 | |
| 1.8 | 90 | 178 | 270 | |
| 2.0 | 80 | 176 | 240 | |
| 6 | 1.0 | 200 | 219 | 600 |
| 1.2 | 165 | 217 | 490 | |
| 1.5 | 130 | 215 | 390 | |
| 1.8 | 110 | 218 | 330 | |
| 2.0 | 100 | 220 | 300 | |
| 7 | 1.0 | 240 | 264 | 720 |
| 1.2 | 200 | 264 | 600 | |
| 1.5 | 160 | 264 | 480 | |
| 1.8 | 130 | 257 | 390 | |
| 2.0 | 116 | 255 | 348 | |
| The allowable deviation of rated working pressure is±5%; The allowable deviation of compressive deformation is ±2%. | ||||
