Corrugated Flexible Copper Fin Tube Twisting Machine

Applications of Copper Corrugated Twisting Pipes

Copper corrugated twisting pipes are widely used in heat exchangers, including:

• Shell and tube condensers

• Coaxial tube-in-tube condensers

• Heat pumps and solar water heaters

• EGR coolers for heavy-duty trucks

• Shell and tube evaporators and evaporative cooling towers

• Swimming pool heat exchangers, boiler heat recycling, and shower waste water recovery

• Floor heating, driveway snow melts, spas heating, hot tube heating

• Oil cooling or heating, steam condensers, district heating, transmission and engine coolers

Their flexible nature allows easy bending by hand without damage, making them ideal for air conditioner connectors, plumbing, and natural gas water heaters.

Design Factors for Optimal Heat Transfer

Heat transfer efficiency depends on:

• Raw material, pipe diameter, wall thickness

• Spiral groove pitch and depth

• Number of grooves (leads or starts)

These factors are optimized to maximize heat transfer efficiency.

Copper Corrugated Fin Tube Twisting Machine

The twisting machine is designed to produce flexible copper corrugated pipes efficiently. Key features include:

• Spiral grooves formed by three-jaw rollers

• Adjustable groove depth and corrugation pitch

• Groove leads: 3, 4, 6, or 8 (replaceable chuck heads)

• Groove depth adjusted via roller height

• Groove pitch adjusted via roller inclined angle

Servo-Driven Precision & CNC Control

Three servo motors and controllers drive the machine synchronously, providing stable linear, axial, and radial movement.
This ensures consistent pitch and depth of grooves along unlimited pipe lengths.

CNC systems allow production of continuous or disconnected spiral grooves on the same pipe.

Automatic Loading & Unloading

An automatic copper tube loading and unloading system enables fully automated operation, reducing labor and increasing production efficiency.
