Stianless Steel High Flux Tube

High Flux Tube Product Description:

High flux tubing is specifically designed to enhance heat transfer efficiency in the nucleate boiling regime. A thin, porous metal layer or matrix is bonded metallurgically to the heat-transfer surface. Saturated liquid is drawn into the layer by capillary action and vaporizes from the extremely large number of stable generation sites which exist in the structure. Boiling side heat transfer coefficients of 10-30 times that of bare tubes can be achieved, resulting in an overall heat transfer improvement of 2-4 times that of bare tubes.

In new installations, the use of high flux tubing allows reduced exchanger surface area and/or lower utility consumption, resulting in substantial savings in capital and operating costs. For large reboiler duties, the use of high flux tubing can reduce the total number of exchanger shells required, resulting in not only reduced exchanger costs but savings in piping, controls, foundation, and plot plan space. The use of high flux tubing exchangers is particularly attractive for grassroots heavy aromatics separation, natural gas de-ethanizing, heat-pumped propylene/isobutene fractionators, and ammonia plant syngas chilling applications.

In retrofit situations, the use of high flux tubing in existing exchanger shells can allow increased capacity and/or elimination of a new exchanger addition. Alternatively, the use of high flux tubing can allow the use of lower pressure steam at fixed capacity, reducing utility costs. In a revamp situation, the use of high flux tubing, as an alternative to a new exchanger, is particularly attractive due to conservation of plot space, minimum downtime, and short lead-times.

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.
