Submarine rubber fender, also called the hydropneumatic fender, is a kind of pneumatic rubber fender that design for submarine or vessels,semi-submersible and drilling rigs,.It is filled with air and some water to keep it standing vertical in the ocean so that it can protect submarine in the vertical plane.
Hydro-pneumatic rubber fender also made up by rubber and synthetic-tyre-cord, and also has outer rubber,layer-cord and inner rubber.It is also been vulcanized together to withstand tension and pressure and other forces.
Outer rubber: Cover outside of the fender to protect cord layer and inner rubber from other external forces. It has high tensile resistance,tear resistance and wear resistance.
Synthetic-tyre-cord: Maintain the internal air pressure of the fender and strengthen the strength of fender. It can make fenders be more pressure-resistant and small deformation.
Inner rubber: Seals the pressurized air inside the fender to prevent air leakage. It can also keep the inner pressure of the fender.
The size of our submarine pneumatic fender could be customized according to customer's requirement, here are some examples for you to refer to.
