What is the most commonly used shell and tube heat exchanger?
Shell and Tube Heat Exchanger: What Is It? Types, Process
The counter flow is the most popular and efficient type of heat
exchanger. In a cross flow shell and tube heat exchanger, the
fluids flow perpendicular to each other at a 90o angle.

What is serpentine tube?
A tube bent into a shape of a serpentine allows an original
equipment manufacturer (OEM) to extract heat from one environment
and transport that heat to another area. For example, a
refrigerator has heat energy contained within the products that a
user wants to keep cool.Product Show
Special Material ND Steel 09CrCuSb
Special anti dew point corrosion, anti low temperature flue gas
corrosion material ND Steel 09CrCuSb.
Chlorine (Cl- ion) corrosion resistant material. Sulfur (SOx- ion)
corrosion resistant material.
09CrCuSb was originally used on petroleum cracking process, to
against corrosion.
Specifications
1. Add the heat exchange area and reduce the number of tubes, also
increase the fume flow section area to reduce the fume speed and
abrasion.
2. H type fin tube can be made to double H type fin tube, high
rigidness to fit long tube row.
3. H type fin economizer arranged in line to make the space into
many small zones, averaged air flow to reduce the abrasion.
4. With straight channel to gain the best ash-blowing effect.
5. The compact structure to reduce the weight and reduce the
manufacturing cost.
