Many resources and secrets in the ocean are waiting for us to discover. So far we have not been able to understand the vast waters that already existed in the world. In this regard, people are tirelessly improving ship technology to meet the needs of going out to sea, and a product called pneumatic fender has emerged. The marine pneumatic fender is an external collision avoidance safety device, which can effectively protect the side of the ship and reduce the risk of sinking to a great extent. It is the right-hand man of sailors. So what are the requirements for such an important thing when it is produced?Let’s take a look today.
Basic usage requirements
- First of all, the pneumatic floating fender must have good floating performance. Sometimes when the ship is in danger of sinking, the pneumatic rubber fender can ensure that the ship is still floating on the sea, waiting for the arrival of the rescue team.
- The requirement of marine pneumatic fender is very strong, and it needs to withstand the test under the corrosion of various acid and alkali substances in seawater. In addition, when encountering collisions between submerged reefs and marine rubbish, we must not be afraid of being scratched and not afraid of friction.
- Marine pneumatic fenders must not have the risk of blasting. When designing, the internal inflation system of the inflatablepneumatic fender must be strictly inspected, and the tightness must be strictly tested to ensure the use of the marine fender stability.
- The yokohama pneumatic fender must have good energy absorption performance. The so-called energy absorption means that the marine inflatable fender must have a strong deformability to ensure that it can absorb a part of the extruded energy from the outside and then evenly distribute it to each part to ensure that the pneumatic fender Intact.
- The exterior color coating of pneumatic fenders should be high in color fastness, bright and not easy to fade. Especially in some sea areas with relatively bad weather, if the electronic signal is not good, then the color of the inflatable fender on the ship must be used to attract people's attention.
Industry production standards for pneumatic fenders
In addition to the above most basic appearance and functional requirements, pneumatic yokohama fenders have their own industry production standard-ISO17357, which clearly stipulates the performance standards, appearance standards, and testing standards of pneumatic fenders.
For example: ISO17357 requires that the appearance of the inflatable fender should be smooth without bubbles and scratches, the diameter of the flange should be less than 0.2 times the diameter of the sphere, there is a fixed size standard for the size, and the general color is black. In the performance test of the inflatable fender, the leaning ball should be squeezed 3000 times with a force of 10 kN, and the fender should have no cracks and no performance changes. After 1 minute of continuous squeezing, it will recover to 97% within 5 minutes.
These data obtained through many experiments are the lowest standard line to ensure the basic safety of users. The pneumatic fenders produced by Sunhelm have passed the ISO17357 test and certification, and the performance data is far higher than the standard data. So Sunhelm's pneumatic fender is definitely worthy of your trust. With it, you can safely dock with other ships on the ocean and make greater contributions to the development of marine technology. Sunhelm will always be a strong backing for the development of marine technology!
