Feature：
In the application of boilers, after optimization of the heat transfer and flow resistance, the heat transfer efficiency of a corrugated smoke tube is equivalent to 1.7-1.8 root of the same size as ordinary smoke tube. This could not only makes the apparent reduction in the number of smoke tubes, but can also reduce the diameter of the boiler shell, thus, the pressure components of steel consumption has been significantly reduced, saving steel, reduce costs.
