Product Description
Our fenders play a critical role in the safe operation of ship berthing and mooring, and also confirms that all its Pneumatic Rubber Fender fully comply with all requirements of ISO17357 and DNV certificated.
Advantages of Longao pneumatic rubber fender :
1.High Energy Absorption
Energy absorption is one of main technical performance indicator of fenders.With tonnage growth of ships,the collision energy between ship or other vessel and quay during berthing operations has grown exponentially.The huge collison energy should be absorbed by fully deformation and sufficient contact area of fenders.The deflection rate of pneumatic fender can be up to more than 60%,and conntact area will expand fast with the deflection.So its energy absorption is much higher than other fenders.
2.Low Reaction Force
The air in pneumatic rubber fender is low-pressure ,which is hardly be increased during deflection.Because of its large contact area,the unit surface pressure is only 120KN/M acted upon the ship.Obviously it is much lower than other fenders.
3.Good Adaption Of Inclined Contact
For a ship,there should be a certain angle for shore-cinnection.Berth fender has a higher adaption than other fenders when comes to clined contact.
4.Floating On Water,Suitable For Ship Swaying
Floating on water,the position of pneumatic fendedr with respect to the ship will bot be changed during tidal fluctuations.Especially when the ship is rocking with the swell, cylindrical inflatable fenders will roll at same time with same friction.Therefore the coasting of the ship will not be damaged,but also play a role in anti-sway damping.

Company Introduction:
Our company mainly produces marine airbags for ship upgrading and launching and pneumatic and filled rubber fenders. Our products adopt streamline operating program, namely our company uses independently produced raw materials to produce airbags and fenders, such as main framework material twill fabrics, which improves technology on the basis of prior impregnation process and passed provincial identification and certification of Quality Management System; Rubber (twill fabrics rubber), which has formula with strong stability and enough assurance of gel content; Our company is also equipped with gluing equipment (four-roll calendar) specially for twill fabrics, which has strong stability for production of airbags and fenders and is incomparable to other industries of China.
In production technology, our technical personnel summarize a set of effective production processes through continuous grope, our production equipment is improved on the prior basis, and many proprietary technologies of our company formed; Meanwhile, we got passionate guidance from Mr. Qiao Changlin, so we ensure product quality from production technology and raw materials.
Our products are provided to some domestic manufacturers and also exported. At present, many countries and regions, including America, Russia, Japan, North Korea, South Korea, Taiwan, India, Vietnam, Turkey, Indonesia, Singapore, come to China to order airbags and fenders. Now is the upsurge of Chinese airbags, international airbag upsurge also emerges, and the airbags have greatly developed in tonnage of ship upgrading and launching from former dozens of tons, hundreds of tons and thousands of tons to thirty thousand tons. Now China has over 4, 000 small and large shipyards, a part of which have adopted the new technology with low investment and high effect and created good economic benefit and social benefit, and fenders are effectively used in wharfs and ships. Our company solemnly promises to repair and exchange within one year due to poor product quality and freely provide maintenance technology and provide paid raw materials for repairing after one year.
Welcome to our company!
