Pipeline Buoyancy Airbags Units

The weight of ship launching airbags is calculated by airbag surface area. When you care too much about weight, you may be misled by some manufacturers. Please remember “It’s not that the heavier the airbag, the better the quality. Weight is not a good indicator of quality.”

It is very easy to distinguish used and new airbags. If there are abrasions on the airbags body, then it is used one. For the new airbags, it’s surface maybe looks ugly and dirty. It is because we use French chalk in the vulcanization process. When the water vapor in the vulcanization tank is mixed with French chalk, the surface will appear very dirty.

Our unique overall winding technology is different from the current mainstream airbag production technology. We innovate and improve on the basis of mainstream production technology. The airbag produced by the optimal winding angle technology can exert the maximum effect of the material, save the cost, and have a stronger lifting force.

Marine rubber airbags are not single-use products. It can be used for many times. But cannot define the exact number. General speaking marine airbags have 5~8 years lifespan under the correct usage and proper maintenance.

The ship launching airbags price is calculated by the airbag’s surface area, not weight. Rubber airbag has two cone shape ends. But we normally, make the airbags as cylindrical shape to calculate its surface area. Its calculate formal is S=π x Diameter x (Diameter+Effective Length) x layer numbers. Then, multiply the surface area by the unit price. The unit surface price is quite different for different factories, generally it is in the scope of USD4 to USD8 for each square meters.
