Advantage
1.Improve the heat transfer efficiency in the effective space;
2.Reduce the installation space of the required heat transfer surface;
3.At the same time, it has high reliability;
4.The pressure drop on the tube side is reduced and the operation cost is reduced;
5.The stiffness and seismic performance of steel pipe are improved;
6.Heat transfer is strengthened to reduce flow resistance and metal consumption.
Longitudinal finned tubes are produced by resistance welded fins along the length of the tube
The fins first form a U-shaped channel, so that each U-shaped leg forms a fin. The channel is cut to the appropriate length, then oriented and resistance welded in place along the length of the tube. The channel is a pair of welded, opposite, so the number of fins specified must be a multiple of four.
