Compressed Air Filled Pneumatic Fenders For Damage Prevention In Marine Operations
Marine Pneumatic Rubber Fenders are frequently known by other names, such as Yokohama fenders or Yokohama - type pneumatic fenders. These floating pneumatic rubber fenders are made from synthetic - cord - reinforced rubber sheets and filled with compressed air. The air inside serves two vital functions.
Firstly, it enables the fender to stay afloat on the water's surface. This floating ability is fundamental as it positions the fender where it's needed, ready to perform its protective role.
Secondly, in scenarios where two ships are nearing each other or when a ship is approaching a berthing structure, these fenders play a crucial role as shock absorbers. They efficiently soften the impact, safeguarding both the ships and the berthing structures. Without them, the force of contact could cause significant damage to both.
This shock - absorbing feature is of utmost importance in the marine environment. It helps preserve the structural integrity of vessels and marine infrastructure. By minimizing the risk of damage, it reduces the likelihood of expensive repairs. Moreover, it ensures that maritime operations can proceed smoothly and safely, without disruptions caused by damaged ships or structures.
Classification
There are two initial pressure rating for our Pneumatic Rubber Fenders.
■ Pneumatic 50 (P50, Initial internal pressure 50kPa)
■ Pneumatic 80 (P80, Initial internal pressure 80kPa)
There are two common types our Pneumatic Rubber Fenders.
■ Type I - Net Type Covered with a chain net, wire net, or fiber net for small size fenders
■ Type II - Sling Type This type of fender has a lifting device on each end, which shall be connected with a guy chain or guy-rope. Without a protection net, easy to handle with lightweight)
Net - type fenders (TypeⅠ) are characterized by a covering consisting of a chain net, wire net, or fiber net. In these nets, regardless of whether the longitudinal components are chains, wires, or fibers, each end is joined by one or two rings. These rings are subsequently connected to a guy chain or guy - rope.
Generally, to enhance the protection of the fender body, these nets are used in conjunction with tires and rubber sleeves. Nevertheless, when it comes to fiber nets, only rubber sleeves are utilized for this protective purpose.
Among the various types of nets, chain nets exhibit a higher resistance to corrosion. This property enables them to have a longer service life in marine settings where corrosion is a major issue. In contrast, wire nets are lightweight, which makes them more convenient to handle and install. Moreover, wire nets have the benefit of being more straightforward to repair when damaged. This allows for a swift restoration of the fender's functionality. The availability of different net materials gives ship owners and operators a range of choices. They can select the net - type fender that most closely meets their particular requirements, whether it's the durability against corrosion offered by chain nets, the ease of handling of wire nets, or the cost - effective repair capabilities that contribute to overall operational efficiency.
Floating pneumatic rubber fenders are composed of three main components: an outer rubber layer, a reinforcement synthetic - tire - cord layer, and an inner rubber layer. These components are vulcanized together firmly to form a cohesive and functional unit.
Outer Rubber Layer: A Shield for Inner Components
The outer rubber layer plays a vital role in protecting the underlying cord layers and the inner rubber. It is made from a carefully formulated rubber compound. This compound is engineered to possess sufficient tensile and tear resistance strength. Such properties are essential as they allow the outer layer to withstand the various weather conditions it will be exposed to in a marine environment. Whether it's the harsh sunlight, saltwater corrosion, or the physical stress from constant use, the outer rubber layer can endure these challenges. This ensures that the more vulnerable inner components are shielded, maintaining the overall integrity of the fender.
High - Quality Synthetic - Tyre - Cord Layer: Maintaining Air Pressure
The reinforcing synthetic - tyre - cord layer is designed with strength in mind. Its primary function is to maintain the internal air pressure within the fender. This layer provides the necessary structural support to keep the fender inflated and in its proper shape. Simultaneously, the inner rubber layer acts as a seal. It prevents the pressurized air from escaping, ensuring that the fender remains functional. The combination of these two layers - the strong synthetic - tyre - cord layer and the air - tight inner rubber layer - is crucial for the proper operation of the floating pneumatic rubber fender.
Safety Valve: Ensuring Safety in Larger Fenders
For pneumatic fenders with a diameter of 2500 mm or larger, a safety valve is an integral part of the design. This valve is a safety - critical component as it is designed to release any excess internal pressure. In situations where the internal pressure of the fender builds up beyond
ISO certificated with a number of patents on products
Pneumatic rubber fenders have been inspected and approved by Third-Party like CCS, BV, SGS, V-Trust etc with excellent performance of high energy absorption and low force reaction and airtightness.
