ADVANTAGES OF CORRUGATED HEAT EXCHANGER TUBING

"Chipless" Surface Enhancement

A corrugated tube is cold formed, not machined.  The metal of your tube is not introduced to heating or cooling in order to produce this modification. Also, no metal is added or removed in the corrugating process.  The wall thickness in the area of the grooves, is the same as in the plain tube prior to enhancement.

Higher Heat Transfer Efficiency

The wavy or ridged surface of corrugated tubes increases the available heat transfer surface area and induces controlled turbulence. This disrupts the laminar boundary layer, improving mixing and reducing thermal resistance, which boosts overall heat transfer coefficients.

Reduced Fouling  

The swirling flow pattern scours the tube wall, delaying fouling by up to 50% and maintaining performance for longer periods. This reduces the need for frequent cleaning and extends operational cycles.  

Lower Pressure Drop

Turbulence is generated by the corrugations themselves, allowing effective heat transfer at lower initial fluid pressure. This reduces pump power requirements.

Compact Design and Lighter Weight

Greater heat exchange per square foot means corrugated exchangers can be up to 30% shorter and require fewer tubes for the same output.  This allows a shorter unit to be built, reducing material and construction costs, and saving floor space for the end user.

Reduced Stress

The corrugated wall can flex slightly, absorbing thermal expansion stresses and tolerating larger temperature differences without fatigue cracking.
