Marine Rubber Fender Rubber Dock Bumper Super Cell Rubber Fender
FEATURES
1. 1 High energy absorption
The amount of energy absorbed is the main technical performance indicator for inflatable fenders. As the tonnage of the ship grows, the energy of the ship touching the shore The impact energy of the ship contacting the shore wall or other vessels also increases exponentially. The huge impact of energy must depend on adequate deformation of the fender and sufficient contact surface. The compressive deformation of an inflatable fender pneumatic rubber fender can be compressed and deformed by more than 60% and the contact area expands rapidly with the deformation, making it far more capable of absorbing energy than other fenders. The ability to absorb energy is much greater than that of other fenders.
1. 2 Ultra-low back pressure
Pneumatic rubber fenders are filled with low-pressure gas, and the increase of internal pressure in compression deformation is very limited. The increase in pressure is very limited. Due to the large contact area, the unit pressure acting on the surface of the hull is very low. The unit pressure on the surface of the hull is very low, only 120kN per square meter, compared to other fenders. This is not the usual low counter pressure compared to other fenders.
1. 3 Good adaptabilities to inclined contact
For the ship, it is necessary to have the possibility to meet the shore and fender at a certain angle. Possibility. Pneumatic rubber fenders are much more adaptable to inclined contact than others. The pneumatic rubber fenders are much more adaptable to inclined contact than other fenders.
1. 4 Floating on the water, suitable for ship swaying
Pneumatic rubber fenders float on the water and do not change their position about the ship's side as the tide rises and falls. The position of the fender does not change. Especially when the ship is swaying with the waves. The cylindrical inflatable fender rolls along with the ship and the friction is minimal.

During the operation of engineering ships, there is an objective situation of mutual berthing collision, and fender structure is generally used to cope with the external impact. Under the collision and compression of berthing ship, the pneumatic rubber fender structure usually deforms greatly to protect the ship, so the collision and impact performance of fender structure is directly related to the safety of the ship.
