Hot dip galvanized elliptical fin tube:
Using string hot dip zinc process, fin uniform, piece of contact with a solid, good anti-corrosion properties, Elliptical tube on the square fins: special type of finned tube. This finned tube maximizes heat exchanger performance and minimizes heat loss and pressure loss. Widely used in power station air cooler, boiler energy efficiency, power plant waste heat boiler, petrochemical engineering. Because the direct air cooler use the environment of particularity, so the surface of the air cooler to conduct a good anti-corrosion treatment. The surface of the elliptical finned tube is hot dip zinc to improve the service life of the air cooler. The quality requirements of the hot-dip zinc for the elliptical finned tube are not only the general requirements for the quality of the zinc-impregnated zinc-zinc components, but also the special requirements for the quality of the dipping of the elliptical finned tube. Characteristics of hot dip zinc coating Hot dip galvanized on the surface of the protection of steel substrate than paint or plastic layer is much better. Hot dip zinc, zinc and steel between the spread, the formation of zinc-iron intermetallic compound layer, that is, alloy layer. The alloy layer has a multi-layer structure, the chemical composition of these layers is equivalent to Fe3Zn10 or Fe5Zn21, FeZn7, FeZn13 and so on. Alloy layer and steel and alloy layer and pure zinc layer are metallurgical combination.
Rectangular elliptical Copper finned tube:
fin the uniform, piece of contact with a solid, Elliptical tube on the square fins: special type of finned tube. This finned tube maximizes heat exchanger performance and minimizes heat loss and pressure loss.
hot dipped galvanized oval (elliptical) finned tubes, rectangular fin tubes
1. hot dipped galvanized oval (elliptical) finned tubes, rectangular fin tubes ( fin tubes ) is by setting up rectangular or square-shaped fins over Oval tube.
This fin tubes (pipes) maximizes the performance of Heat Exchangers and minimizes the loss of heat transfer and pressure.

Applications include double pipe and multi-tube heat exchanges, fired heaters, gas coolers and tank heaters.
The fins are formed from a U channel of material, with the base of the channel being pressure rolled and spot welded to the tube or pipe.
Can be manufactured from most weldable or brazable materials and supplied in either straight lengths or in U bent form.
The fin channels are welded to the tubes in opposite pairs. Fin height, number of fins and thickness can be uniquely specified.
Fins can be applied to either OD tube or NB pipe.
Fins can be either solid or perforated to suit the application.
