Marine Fender Aircraft Tyre Chain Inflatable Fender ISO17357 Standard
There are two types of inflatable fenders
1, sheath type
The sheath type of ship's fender is covered with a sheath, which consists of a chain, or a nylon rope net, and old tires (or rubber sleeves). The longitudinal break point of the chain or nylon rope net is connected with one or two mesh holes of the adjacent mesh set with a cable or pull rope. The mesh set will be attached with a tire or rubber sleeve to provide protection for the fender body.
2. No sheath type
Fender without sheath type inflatable rubber fender is the fender without net tire chain coverage outside the surface. This kind of fender is light and easy to move, and makes the fender move more flexibly in the work, so as to deal with the impact from various angles.

Pneumatic rubber fenders introduction:
Pneumatic rubber fender is a kind of ship supplies for berthing buffer and protection. Pneumatic fender is more practical and economical than general ship fender, so it is popular.
Marine fender is a rubber airtight container made of gluon cloth as skeleton material. The fender is filled with compressed air and can float on the water. It serves as an important buffer medium for berthing between ships and docks. At the same time, inflatable rubber fender can absorb the impact energy of ship movement, reduce the ship's recoil force, and greatly improve the safety of ship docking.
With air as the medium, the compressed air is used to absorb the impact energy, so that the ship is flexible when docking, so as to achieve the effect of collision prevention and avoidance. Yokohama fender has been widely used in oil tankers, container ships, engineering ships, ocean-going fishing boats, offshore platforms, large docks, military ports, large bridge piers and other ships and offshore platforms.

Instructions for operation and maintenance
1. The maximum deformation of Marine inflatable fender in the use process is 60% (except for special ship type or special operation), and the use pressure is 50kpa-80kpa (the use pressure can be determined according to the user's ship type, tonnage size and near environment).
2, pneumatic rubber fender should pay attention to avoid sharp objects in the use of puncture and scratch; And timely maintenance and maintenance, in general 5- 6 months for a pressure test.
3. Check regularly whether the inflatable fender body is puncted or scratched. The surface objects in contact with the fender shall not have sharp protruding hard objects to prevent puncturing the fender. When the fender is in use, the cable or chain or wire rope hanging the fender shall not be knotted.
4. When the fender is not used for a long time, it should be cleaned and dried, filled with appropriate amount of gas, and placed in a dry, cool and ventilated place.
5. The fender should be kept away from heat, and should not contact with acid, alkali, grease and organic solvent.
6, do not pile up when not in use, do not pile up heavy objects on the fender.
