Lord Fin Tube-Corrugated tube or enhanced surface tube

Our company works with the German heat transfer technology company to enhance the condensation heat transfer of organic compounds by using high efficiency condensing tubes. In addition to the traditional low finned tube which enlarges the heat transfer area on the surface of the tube, its unique processing technology makes the fin tip form a special three-dimensional structure with rapid drainage function, which is conducive to thinning the condensate film and further improving the condensation heat transfer efficiency. At the same time, the processing technology adopted by this technology, compared with the traditional low finned tube processing stress is small, can effectively extend the service life of heat exchanger tube.

Its applications include refining, chemical, power, refrigeration, air-conditioning and other industries condensing conditions.

High efficiency condensing pipe can be made of carbon steel tube, austenitic stainless steel, titanium, copper and copper nickel alloy and other materials.

Corrugated tube

Corrugated tube enhanced  technology is for no-phase and condensing heat transfer. The key of this series is the corrugated or helical shape, as liquid flow through the tube, it could disturb the liquid fluid and break the boundary layer of laminar flow on both outside and inside. The increase of turbulence will improve heat transfer, and the spherical hump will shrink the condensate film on the outer tube surface which will raise the condensation heat transfer coefficient. Also, the increase of turbulence could help avoid dirt deposition on the tube surface, delay equipment scaling.

The main feature of this technology is high heat exchange efficiency, low scaling, and better self thermal compensation. Compare to the traditional plain tube, it also has the advantages as easier to operate and maintain, better energy-saving effect, and it is the energy saving produce which generalized by Ministry of Science and Technology.

Based on the shape of the tube, the corrugated tube could separate as thin-walled corrugated tube, thick-walled corrugated tube and spiral corrugated tube.

Main application is almost including all fields, such as fertilizer, soda ash, oil refining, petrochemical industry, coal chemical industry, thermoelectric and city heat supply.
