Characteristic Manufacturing Process

Pickling Process

Using a unique pickling process, the heat exchanger shell is pickled to remove oil, oxide scale and rust, and form a dense phosphate film to protect the shell. Prevent the shell from being oxidized and rusted again during the manufacturing process, thereby effectively ensuring the cleanliness of the refrigeration system.

Drilling Technology

The important process of heat exchanger manufacturing adopts high-end CNC machining center. Drilling, grooving, and boring use patented tools and are finished by 6 processes. Long-term guarantee the sealing performance of the expanded tube position.

Expanding Process

Adopt German CNC tube expansion equipment. According to the tube diameter and wall thickness of the heat exchange tube, the expansion tube head and torque are selected. High-end equipment and rigorous process control effectively guarantee the quality of the tube expansion and ensure the safety of the tube expansion process.

Welding Process

Using American Miller welding machine and ASME standard CO2 flux cored welding wire. According to the characteristics of each product, the welding process specification is formulated. Ensure that each weld of the product is beautifully formed and has no defects.
