Manufacturing Process of Condenser Coil

Manufacturing Process of Condenser Coil

The following are the main manufacturing processes for condenser coils:

Bending process:

Mechanical bending: the use of pipe bending machine through the mould to bend the pipe, this method is suitable for larger pipe diameter and thicker wall coils.

Hydraulic bending: the use of hydraulic systems to provide the power to bend the pipe, can achieve a more accurate bending angle and radius control.

Welding process:

Manual welding: rely on the manual operation of skilled welders for welding, suitable for small quantities or special shapes of coiled tubes.

Automatic welding: such as argon arc welding automatic welding, stable welding quality and high efficiency, commonly used in mass production.

Expansion process:

When connecting the coiler with the tube plate, the tube end is plastically deformed by the expansion tool, so as to achieve a tight connection.

Cutting process:

Laser cutting: high precision, smooth cut, suitable for cutting coils with strict size requirements.

Sawing: Sawing is a common cutting method for pipes with large diameters.

Surface treatment process:

Galvanised: enhances the rust and corrosion resistance of the coils.

Painting: Provides additional protection and aesthetics.

Leak testing process:

Hydrostatic test: Fill the coil with water at a certain pressure to check for leaks.

Gas tightness test: Use gas (e.g. nitrogen) to test for tightness.
