Raopian finned tube

The wound finned tubes are all made of (steel, aluminum, copper, stainless steel, etc.) with wound (steel, aluminum, copper, stainless steel, etc.) tubes, and pass through
Mechanical strong winding, spiral shaped, with three different sheet distances: 3.2mm "R", 4.2mm "M", 6.5mm "T".
R-spacing, small spacing but large heat dissipation area, with large heat dissipation;
M-spacing, with a larger spacing, results in lower heat dissipation and air resistance;
T-spacing is suitable for situations where steam pressure is high and air temperature rise is low.
