Heat exchange tubes

The feature of high flux heat exchange tubes is that powder iscomposed on the base metal of heat exchange tube to change the status of boiling surface to form porosity between particles and form nucleate boiling center, so as to change the membrane-shaped boiling into nucleate boiling and significantly improve the boiling heat transfer coefficient.

Technical specifications:

-Dimension: diameter 15~51mm, Length:1~15m

-Porosity of the porous layer: 40%~80%

-Pore size of the porous layer: 30~70μm

-Shear force of the porous layer:≥150N/mm

-Total heat transfer coefficient: ≥3000W/(m2.K)

-Materials: carbon steel tubes, stainless steel tubes, copper and copper alloy tubes.

Features:

-Double sides reinforced structure is used, such as outer longitudinal slots with inner porous or outer porous with inner slots.

-High critical heat load. The critical heat load of high flux heat exchange tube is about twice of that of ordinary tube.

-The boiling could be maintained at small temperature difference. With the same heat flow intensity, the effective temperature difference required by high flux heat exchange tube is only 10~15% of that of ordinary smooth tubes

-Excellent anti-blockage capacity and scalling resistance performance

Applications:

Heat transfer of liquid-gas phase changing and boiling in the petrochemical, chemical and metallurgy industries, sea water desalination, natural gas storage and transport, air separation and refrigeration.
