Fluted / Sintered Copper Nickel Heat Exchanger Tubes OD 19 , 25 , 32mm OHSAS18001

High Flux Tube

High flux tube can be classified into three groups: sintered high flux tube, sprayed high flux tube and machined high flux tube. Among them, sintered high flux tube is the most expensive for its complex processing method and high efficiency; machined high flux tube is applied to mediums with high surface tension, its performance is in between; sprayed high flux tube is the cheapest for its easy process and low efficiency.

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

Material and size of High Flux Tube

Material: nickel-copper alloy (C70600, B10), carbon steel (SA179,10#), aluminum alloy (3003), stainless steel (304L, 316L) and so on.

Size: OD 19, 25, 32mm,

Length 2000-14000 mm

Under normal condition, the middle of High flux tube is enhanced section. Both ends are smooth. It is easy to wear tubes and easy for expansion joints. We are OEM of high flux tube and can produce according to customers' needs. Products are packaged with wooden boxes.

Applicable medium of high flux heat exchangers

Ethylene glycol, light olefin, refrigerant, liquid oxygen, liquid nitrogen.

Applications of high flux heat exchangers

High flux heat exchanger can be used in phase change equipment, such as, carburetor, evaporator,

reboiler and condenser, etc.

Sintered High Flux Tube

Sintered high flux tube is a new product combining metal powder sintered method and machining technology. It can improve the heat transfer coefficient of the inside and outside tubes, thus it can significantly improve overall heat transfer coefficient of heat transfer tubes.
