Don't know if any of you have used those products or know anything about it.

this is what I saw from an troduction of high flux tube:

High flux tube is a new product combining sintered method and machining technology. They can improve heat transfer coefficient of the inside and outside tubes , thus they can significantly improve overall heat transfer coefficient of tubes. They solve the current problem that heat transfer coefficient increased only on one side of heat transfer enhancement, while the total heat transfer efficiency is still low. They greatly improve the efficiency of the heat transfer tubes and heat exchangers.

On the one hand, High flux tube can reduce the steam demand. On the other hand, it can improve the heat transfer capability. In a large heat transfer system, because of the need of small temperature differences, the number of reboilers needed is very large. The use of High flux tube can reduce 3/4 the amount of reboilers, and temperature difference ΔT needed for only 5 ℃. Using High flux tube to replace traditional bare tube we can eliminate heat transfer bottlenecks, meet the need of larger heat transfer load, and significantly increase production. At the same time, while keeping machine efficiency, it can reduce cost by using lower steam pressure.

The case-hardened products are as follows:
Sintered porous coating for the outer surface/low fins for the inner surface, Cannelure for the outer surface/ sintered porous coating for the inner surface, Sawtooth surface for the outer surface/ sintered porous coating for the inner surface, fins for the outer surface/ sintered porous coating for the inner surface.

1.1 Material and size of High flux tube
Material: carbon steel, Aluminum, and so on.
Size: external diameter 15~40mm,length 500~12000 mm
Under normal condition, the middle of High flux tube is strengthened section. Plane ends are smooth, so it is easy to wear and to be expanded. High flux tube can do OEM as customers’need. Products are packed with wooden boxes.

1.2 Applicable medium of high flux heat exchangers
Ethylene glycol, diethylene glycol, ethylene trichloride, ethane, propylene, ethyl alcohol.

1.3 Applications of high flux heat exchangers
High flux heat exchanger can be used in phase change equipment, such as, carburetor, evaporator, condenser and reboiler, etc. To be specific, such as ethylene carburetor, the overhead condenser and reboiler of ethylene separation device , combination plant of ethylene glycol evaporation and aromatic, main condenser-evaporator of air separation unit. As well as the natural gas liquefaction, cryogenic refrigeration, air separation, and sea water desalination, etc.

And bellow is the company where I quoted the above sayings:

Jiangsu Xinyi Heat Exchanger Science & Technology Co. Ltd.is a private enterprise, it’s registered capital is 10 million RMB with the plant area of thousands of square meters. Headquarter is located in beautiful Wuxi City in Jiangsu province, the branch is located in the international metropolis Shanghai.

The products are varieties of high efficiency heat transfer tube, heat exchanger and related technical consulting services. Flagship products are the high flux tube, twist flat-tube and vertical fluted tube. The company committed to high efficiency heat transfer, waste heat recovery and environmental protection projects.

well, what do you think?
