Low Integral Fin Tube.
Low Finned Tubes add short fin in the tube wall that greatly increase the surface area over smooth tube. The fins are formed into the tube wall so the outside diameter of the fins are not larger than the pre-finned smooth tube. DATANG is solely focused on producing the largest variety and most complete solutions for finned tubing. Low finned tubes can be provided with a smooth or rifled tube inside surface.
Low Fin (Integral) tubing is a type of extruded tubing that consists of short low fins. The low fin tube have the advantage of adding surface area to a smooth tube while maintaining the same outside diameter. Low Fin Enhanced tubes can be used in standard shell and tube baffles and tube sheets.
Rifled Low Finned Tube has the outside diameter surface characteristics of Low-Finned Tubes with the added enhancement of inside diameter rifling. The rifling grooves promote turbulant flow and better heat transfer through the tube wall.

Thermal Properties of Tube |
Enhanced Surface Tubes has specifically designed outside and/or inside tube surfaces. These enhancements increase surface area and change the flow characteristics of the fluids or gas.
Condenser Tubing is specially designed Low Finned Tube with both inside and outside features. The unique features reduce surface tension of gas or liquid to encourage condensing or evaporating.

Description of Spiral Finned Tubes:
The spiral fin steel pipes currently used are mostly wound, high frequency welded and brazed spiral fin steel pipes.
High Frequency Welded Stainless Steel Spiral Fin Tubes Carbon Steel Spiral Finned Tubes Factory Provided
The advantages of spiral fin steel pipes are as follows:
1. Long service life, is more than 20 years;
2. The surface of the fin is smooth, and it is not easy to produce ash accumulation, ash blocking and slagging.
3. It has good density, yield strength, tensile strength and wear resistance of metal structure.
4. The welding quality is high, so that it is not easy to cause unstable heat transfer performance because of fin loosening and falling off.
Application of Spiral Fin Tubes:
Waste heat boiler tube;
Economizer tube;
Power station boiler tube;
Marine boiler tube;
Heat exchanger
