Corrugated Flexible Copper Fin Tube Twisting Machine

Corrugated Flexible Copper Fin Tube Twisting Machine

Copper corrugated fin tubes offer better performance for vortex flow rate in heat exchangers. It features to increase heat transfer, reduce pressure drops, increase heat transfer surface area, eliminate damaging vibration, reduce dead spots resulting from accumulated fouling, etc.



The copper corrugated twisting pipes are widely used in various fields related to heat exchangers. like shell and tube condensers, coaxial tube in tube condensers, heat pumps, solar water heaters, EGR coolers of heavy-duty trucks, shell and tube evaporators, evaporative cooling towers, swimming pool heat exchangers, boiler heat recycling, shower waste water heat recycling, spas heating, hot tube heating, floor heating, driveway snow melts, oil cooling or heating, steam condenser, district heating, transmission and engine cooler, boiler sample cooler, waste water heat recovery, etc.

Especially with its flexible nature, it can be easily bent with bare hands but not damaged.

The copper flexible fin tubes are widely used as connectors for air conditioners, plumbing, natural gas water heater, etc.

Factors like raw material, pipe diameter, wall thickness, spiral groove pitch, groove depth, and number of grooves (leads or starts) interact with each other, and people are committed to studying the optimal combination to maximize heat transfer efficiency.

The copper corrugated fin tube twisting machine is an ideal equipment to manufacture such flexible copper pipes. The corrugated pipe is spiral grooved by three jaws with rollers, groove depth and corrugation pitch can be adjusted.

And leads or starts of groove flutes can be 3,4,6,8 by replacing chuck heads, groove depth adjusted by forming rollers’ height, and groove pitch adjusted by forming rollers’ inclined dip angle degrees.

The spiral copper tube twisting machine is driven by three sets of servo motors and servo controllers.

They are working synchronously to provide stable linear, axial, and radial movements while keeping them at the same rate, resulting in a stable and consistent pitch and depth of the grooves with limitless pipe length. Benefiting from the equipped CNC systems, the tube twisting machine is able to manufacture continuous or disconnected spiral grooves on the same pipe. The automatic copper tube loading and unloading system makes all works fully automatic.
