Industrial High Performance High Flux Tube

High Flux Tube Product Description:

High flux tubes can be classified into three types:

a: sintered high flux tubes;

b: sprayed high flux tubes;

c: machined high flux tubes.

Sintered High Flux Tube is the most expensive for its complex processing method and high efficiency among them.

High flux tubes can reduce the steam demand. It can also improve the heat transfer capability. In the large heat transfer system, demands from small temperature differences, the number of reboilers needed is very big. The usage of high flux tubes can reduce 3/4 the amount of reboilers, and temperature difference ΔT asks for only 5 ℃. Using high flux tubes to replace traditional bare tubes 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.

High Flux Tube(Copper High Flux Tubes) Manufacturing Process:

Sintered high flux tube is a highly efficient heat exchange tube with a specific structure on the surface of ordinary heat exchange tube, which is sintered by powder metallurgy method.Sintered high flux tube is a new product combining metal powder sintered method and machining technology.

Sprayed high flux tube is one type of high flux tubes, with porous coating outside.The coating on sprayed high flux tube is formed by spraying guns which melt and spray the compound of Ni-wrapped Al powder and pore-forming materials.

Machined high flux tube is a kind of high efficient heat transfer tubes manufactured by rolling process of bare tubes, the structural features are a series of spiral-ring T type tunnel, which are formed in the outer surface of the tube.

High Flux Tube(Stainless Steel Flux Tubes) Advantages:

1.The thermal conductivity is 10 times as high as that of the ordinary smooth tube

The heat transfer coefficient of sintered surface porous tube can be more than 10 times that of smooth tube. Improving the heat transfer effect by a large margin, reducing the heat transfer surface area by about half, or adopting the same heat transfer area can greatly increase the heat transfer effect and increase the load.

2.Keep the nucleate boiling under small temperature difference

At the same heat flux, the effective temperature difference required by the porous tube is only 1/10-1/15 of that of the ordinary smooth tube.

3.Critical heat flux density is more than 2 times as high as that of ordinary smooth tube

It can delay the occurrence of membrane boiling and improve the load and safety performance.
