Understanding the Extrusion and Cold Drawing of Air Conditioning Connect Copper Corrugated Pipe

The manufacturing process of air conditioning connect copper corrugated pipes involves extrusion and cold drawing to shape and refine the copper material into the desired corrugated tube form. These processes are critical in creating flexible and efficient pipes for air conditioning systems. Here's an overview of the extrusion and cold drawing stages for air conditioning connect copper corrugated pipes:

Extrusion:

Billet Preparation: The process begins with the billets obtained from the casting and melting stage. These billets are cylindrical shapes of solidified copper with a consistent diameter.

Preheating: Before extrusion, the billets are preheated to a specific temperature to enhance their malleability and make them easier to shape.

Extrusion Process: The preheated billets are fed into an extrusion machine equipped with a specially designed die. The extrusion process involves applying pressure to the billet, forcing it through the die, which has the desired corrugated shape.

Corrugated Forming: As the billet passes through the die, it takes on the corrugated shape, with ridges and valleys forming along its length. The extrusion process ensures uniformity and consistency of the corrugations.

Cutting and Cooling: After the extrusion process, the continuous corrugated copper pipe is cut to the desired length. The freshly extruded pipe may be cooled with water or air to stabilize its shape and structure.

Cold Drawing:

Annealing: The extruded copper pipe may undergo an annealing process to relieve internal stresses and improve its ductility. Annealing involves heating the pipe to a specific temperature and then gradually cooling it.

Drawing Process: The annealed copper pipe is pulled through a series of dies of decreasing size. This cold drawing process elongates the pipe while reducing its diameter. The pipe may be drawn multiple times to achieve the desired dimensions.

Final Shaping: The cold drawing process refines the corrugated pipe, further improving its dimensional accuracy, surface finish, and overall quality.

Final Annealing (Optional): Depending on the application and desired properties of the corrugated pipe, a final annealing step may be performed to achieve specific mechanical and thermal characteristics.

The extrusion and cold drawing processes play a crucial role in transforming copper billets into flexible, efficient, and high-quality air conditioning connect copper corrugated pipes. The corrugated design enhances the pipe's flexibility and allows it to accommodate bends and movements in air conditioning systems. The resulting pipes are durable, corrosion-resistant, and efficient in facilitating the flow of refrigerants and coolants, making them essential components in modern air conditioning applications.
