Safety valve type Yokohama pneumatic fender pressure is stable, safe and reliable
The types of Yokohama pneumatic fender tire chain nets are as follows:
The tire chain net is divided into: ordinary car tires, truck tires, aircraft tires; aircraft tires are the most wear-resistant (but the cost is relatively higher), the chains and shackles used must be hot-dip galvanized; the outside of the chain must be covered Protective tube, the protective tube is to protect the chain from abrasion and fender body, and the other is to protect the hull from damage.
Large-size Yokohama pneumatic fender transportation method:
Large-scale Yokohama pneumatic fenders often encounter the problem that ultra-wide and ultra-high containers cannot be shipped during transportation. In fact, we can release the marine fender gas and then fold it so that neither the container nor the trailer will be due to the ultra-wide, It is too high and refuses to ship or increases the high transportation cost; but the manufacturer of pneumatic rubber fender deflation also needs experience and cannot blindly deflate
Pneumatic marine fender structure:
Pneumatic marine fenders are divided into: inner rubber layer, reinforced cord layer, and outer rubber layer.
The role of the inner rubber layer: to shape the fender, enhance air tightness, and ensure no air leakage.
Strengthen the connection layer: increase the strength of Yokohama fender, increase tensile strength, and increase pressure.
Outer rubber layer: improve the abrasion resistance of marine fenders, better protect the body of the inflatable rubber fender, and extend the service life
Yokohama fender instructions and maintenance precautions
1. The maximum deformation of the pneumatic rubber fender during use is 60% (except for special ship types or special operations), and the working pressure is 50KPa-80KPa (the working pressure can be determined according to the user's ship type, tonnage, and surrounding environment).
2. When using pneumatic rubber fenders, care should be taken to avoid punctures and scratches from sharp objects; and timely maintenance and maintenance should be carried out. Under normal circumstances, a pressure test should be carried out every 5-6 months.
3. Frequently check whether the pneumatic marine fender body is pierced or scratched. The surface objects in contact with the fender shall not have sharp protruding hard objects to prevent the fender from being pierced. When the fender is in use, the cable, chain, or steel wire rope that hangs the fender must not be knotted.
4. When the marine fender is not used for a long time, it should be washed, dried, filled with proper amount of gas, and placed in a dry, cool and ventilated place.
5. The fender should be stored away from heat sources, and should not be in contact with acids, alkalis, greases and organic solvents.
6. Do not stack when not in use, and do not stack heavy objects on the fender.
