Product Description

NanHai - Pneumatic Rubber Fenders Series

NanHai - Pneumatic Rubber Fender (CTN).

Named NanHai - Pneumatic Rubber Fender, because of his High Performance in protective,
Various performance indicators beyond International Standard ISO17357. Protect Ship Safety Fully.
Burst pressure factor highest could reach 5 times Than international standard.

NanHai - Pneumatic Rubber Fender Application As one ideal protection tool for Marine application, NanHai - pneumatic fender has become a protection medium against collision among ship-to-ship (STS), ship to quay (STQ) and ship-to-berthing (STB), they are widely used for large tankers, vessels, docks, harbor wharfs and ocean platforms. It uses compressed air as a buffer medium to absorb the impact energy of ship. Therefore, compared with general compressed rubber fender, it has large energy absorption, small reaction force, large contact area with the ship, and can be adapted to the ship's docking in all directions.

NanHai-Pneumatic Fenders consists of 3 different layers: the outer rubber layer, the synthetic-cord layer for reinforcement and the inner rubber layer, With the feature of the soft reaction force. They are supplied with two different inside pressure levels to cover a wide performance range. They are manufactured according to ISO 17357-1:2014.

Net type pneumatic fenders are fitted with a chain-tyre net. The chain-tyre net consists of used tires that are connected by a network of horizontal and vertical chains, which adds further protection to the fender body.

Outer rubber layer

Rubber layer that covers the outside of the fender to protect the cord layers and the inner liner rubber from abrasion and other external forces.

Synthetic-tyre-cord layer forreinforcement

Layer made of synthetic-tyre cordfabric, whichmaintains the internalair pressure of the fender.

Inner rubber layer

Liner of a rubber membrane thatsealsthepressurized air insidethe fender.

CLASSIFICATION OF PNEUMATIC SHIP RUBBER FENDER

Fender types:

1.Net-type fenders: fenders which are covered by a tire chain net, each end shall be linked together with one to two ring(s).

2.Sling-type fender: fenders which are designed to be used without a protection net.

PERFORMANCE CALCULATION OF NANHAI - PNEUMATIC FENDER

The volume of the fender at free state is Vo, and the interior pressure (i.e. original pressure) is Po; when the fender is compressed by dx, its volume is Vx, its interior pressure Px, and its contact Sx.
Its counterforce, Rx, can be calculated as follows: Rx=Px:Sx
At this time, its energy absorption, GEA, calculated as follows: GEA=JxoRxdx
The curve of interior pressure Vs deformation relationship during fender compression test is listed in Table Size, performance and weight of pneumatic rubber fender
