Product Description

ISO17357 Pneumatic Rubber Fender Net Type
Pneumatic Rubber Fender
Inflatable rubber ball (also known as fender) is a kind of ship's articles for berthing buffer and protection, which is widely used in ships, offshore facilities, offshore platforms, ports, yachts and other fields.
The inflatable rubber ball is more practical and economical than the general rubber fender, so it is popular.
Deyuan inflatable rubber docking ball is a rubber airtight container made of hanging rubber cord fabric as skeleton material. After being filled with compressed air, it can float on the surface of the water and serve as an important buffer medium for ship and ship berthing STS (Ship and Ship) and ship and dock (SHIP and Dock).
At the same time inflatable rubber ball can absorb the impact energy of ship movement, reduce the ship's recoils, greatly improve the safety of ship berthing.
The inflatable rubber ball of Deyuan selects the national standard first-class rubber, reasonably adds various preservatives, anti-aging agent, rosin and other additives. The inflatable rubber ball is used in extremely harsh environment for a long time, and is corroded by seawater and exposed to sunlight for a long time.
Through scientific ratio, the surface of aerated rubber ball has abrasion resistance, seawater corrosion resistance and aging resistance.
USES the integral cross winding technology, made by the ball impact strength on the basis of the original process provides a 2 times, and through scientific vulcanization process, make the product more flexible and flexibility, stainless steel flange, sheathed bound can be used to Marine polymer fastening rope and chain two bundles, antirust effect is 10 times higher than the metal flange, our company production of inflatable rubber stamping by ball using nitrogen, nitrogen gas is a kind of relatively stable, contains a large number of moisture in the air, nitrogen does not contain any water, not rubber layer caused by moisture moisture layer,
Nitrogen will not expand and contract with the change of ambient temperature like air, so it can play an explosion-proof effect.
After years of market reaction, the service life of inflatable rubber ball produced by Deyuan company is 3-5 years longer than that of ordinary rubber ball.
Type of Fender
According to ISO 17357:2002 < ships and marine technology, high pressure floating inflatable rubber berthing ball > > has the following classification
1. The leaning ball can be divided into:
a) Sheath type
b) Hanging type
2. According to the initial internal pressure, the leaning ball can be divided into:
a) Type 50 (initial internal pressure is 50kPa)
b) Type 80 (initial internal pressure is 80kPa)
Structural Features of Marine Fenders
The basic structure of marine berthing ball is composed of outer rubber layer, synthetic wire rope reinforced rubber layer and inner rubber layer. It is a cylindrical leaning ball with hemispherical indenter at both ends.
Outer Rubber
The outer rubber layer covers the outside of the fender to protect the synthetic rope and the inner rubber layer from abrasion and the impact of other external forces. This compound has strong tensile strength and tear strength, and can be used in any weather conditions and harsh conditions. The standard colour is black, but other colours such as grey and cream white are also available on request.
Internal Rubber
The rubber film gasket seals the compressed air in the fender.
Safety Valve
A safety valve is provided on the large-sized leaning ball to release excessive internal pressure when the leaning ball is accidentally over compressed.
Metal Fittings
All the related metal accessories of marine berthing ball, including shackle, traction ring, swivel ring and chain mesh, are made of stainless steel and hot dip galvanized (HDG) (hot dip galvanizing can resist seawater corrosion).
Marine Mooring Chain and Tire Net
Almost all are protected by the tire chain and the ball. Chains and tire nets are designed to prevent damage to the sphere by sharp objects or protrusions, such as a rough shore wall that distributes absolute force along the chain mesh.
Testing of Rubber Fenders
According to ISO 17357:2002, the ship's berthing ball should be tested when it leaves the factory
1. Rubber material test, including outer rubber and inner rubber.
2. Dimension Inspection
The dimension inspection of marine berthing ball should be completed under the initial air pressure, and the dimension deviation is as follows:
a) Length: + 10%, - 5%;
b) The diameter was + 10%, - 5%;
The diameter should be measured at least at two or more locations near the middle of the ball and averaged.
3. Air tightness Test
When the air is inflated by the ball to reach the initial internal pressure, there should be no leakage within 30 minutes.
4. Hydrostatic Test
When the inner pressure reaches 10KPA, the longitudinal length and circumferential length are recorded. Continue to fill with water, when the internal pressure reaches the 0% deformation test pressure listed in Table 4 or table 5, keep it for 10min, there is no water leakage, and there is no damage to the ball.
