0.8-2m Ship Marine Salvage Air Bags With Pressure Gauage

Product Description:

1.Standard size of marine airbags

Diameter(D):0.8~2.0m

Effective Length(EL):6~18m

Total Length(TL):7~19.5m

2 Standard number of layer

In order to confirm airbag's safety working pressure

we define the number of layers,which means the

number of synthetic-tire-cord layers.Normally we

offer marine airbags with 4,5,6,7,8 layers.Other
