Stainless Steel Carbon Steel Spiral Finned Tube OD 12.7mm 15.88mm
Stainless Steel Carbon Steel Heat Exchange Spiral Finned Tube
Integral low fin tube has the advantage that it can improve the thermal performance of a heat exchanger without the necessity forchanging shell size, flow arrangement or the repositioning of piping. The external surface of the tube is increased by theformation of "low fins" by direct extrusion from the material of the base tube.

Advantage:
1. 99%-100% fully welded, with high thermal conductivity
2. Extremely strong anti-corrosion ability
3. Enhanced structure due to the welding process
4. Flexible as straight tube or bent or coiled heat exchangers
5. Low heat resistance between fins and tube
6. Strong resistance to shock and thermal expansion and contraction
7. Cost and energy saving due to long service life and high exchange rate
