The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.

Competitive Advantage:
1. The energy absorption doubles comparing with the super cell rubber fender with same spec.
2. In the case with similar reaction force and energy absorption, small size TD-AA cone type fender can substitute relative large TD-A super cell type fender.
3. In the case of oblique berthing (less than a angle of 10° ), the performance can not be reduced, which is preferred to TD-A model.
4. The frontal frame (steel frame) are installed in front of fenders, which can reduce the surface pressure against vessel hull. The surface can be limited below 25t/m2, which is suitable to large vessel especially.
5. The super high density polyethylene pads are adhered to the frontal frame, which can reduce the friction factor between hull and fender to below 0.2, and can reduce the shear (horizontal force) exerted on fenders when vessel berth, which can prolong the service life of fenders.
6. The frontal frame adopts water-tight structure with high strength and better anti-rust performance.
Quick Detail:
1. Deflection can reach to max. 72%;
2. High energy absorption, low reaction force;
3. The 3rd generation of cell type rubber fender;
4. Advanced technology and abundant experience;
5. Easy to be installed.
Applications:
The cone rubber fender is rarely damaged or impaired, because it never contacts the hull directly.
The utilization scope:
1). Suitable to the quays need low reaction force and high energy absorption;
2). Specially suitable to the quays require low hull pressure;
3). Suitable to oil terminal, container terminal and offshore berths;
4). Suitable to any case using super cell fenders.
