Pneumatic rubber fender is the advanced anti-collision device for marine application in the world. It is made of synthetic nylon lines and compressed rubber sheet. With inner compressed air, it can float on the water and widely used as protecting medium. It is usually used as an important protecting medium to prevent a collision in craft works and mooring works.
 
Advantage and application:
Compared with traditional bumper-style rubber fender, it has the following features, absorbing greater impact, less reverse impact on the ships, easy installation, more elasticity, not being bent out of shape under pressure, less weigh and practical and economical. So pneumatic fender has widespread application on oil tankers, container vessels, luxury yachts, ocean platforms, larges shipyards, military ports and larger underwater foundations of bridges, etc.
Purpose
1. Installed in the terminal and dock, used the ship shore and landing.
2. Installed in the ship board, used the ship close to ship.
3. Can as float rod on the sea.
4. Can used carry goods on the sea
5. Used airproof pipe
Specifications:
1. Small-scale Diameter: Less than 1meter; Length: Less than 1.5meter
2. Medium Diameter: More than 1meter, Less than2meter; Length: More than 1.5meter, Less than 4 meter.
3. Large-scale Diameter: More than 2.5 meter; Length: Length basis customers' requirement
Since we own a professional technicians team, so the most advantage is that we can suggest you the most suitable quantity of airbags needed according to the actual condition of the ships and structures, which can avoid wasting the labor, cost and time. Our mission is provide world class goods to customer, so we guarantees high standards and performances of all products. Customer requirements are strictly followed during all production phases.
Storage of pneumatic rubber fender
1. When not using for a long time wash the fender surface, dry up and fill in sufficient right of compressed air to lay in a cool dry and well-ventilated place
2. The storage place of pneumatic rubber fender should be far away form heat source
3. Try to keep fender away from acid alkali grease and organic solvents.

The cold rolling mill is an advanced equipment that continuously rolls blades from strip steel. By adjusting the position (roll offset, feed height, roll pressure, guide wheel, etc.), it can roll out blades of various specifications required.
Advantages of cold rolling layout:
It has the advantages of high production efficiency, saving raw materials, good blade quality, high hole diameter, and good wear resistance.
The structures that affect the rolling shape include the material and thickness of the strip, the offset of the roll, the feeding height, the rolling force of the roll, the different specifications of the guide wheels and blades, and the increase in the temperature of the roll during the rolling process. After years of construction, the contract developed this continuous cold-rolled propeller, which has the advantages of smooth surface, high hardness, wear resistance, one-time forming, and continuous no welds.
