How are the copper branch pipes of air conditioner accessories processed?

The copper branch pipes of air conditioner accessories are very important in refrigeration and air conditioning. It affects the overall use effect of air conditioners. So how are the copper branch pipes of air conditioner accessories processed?

The copper branch pipe of air conditioner accessories is a very important raw material. It has the function of making heat exchangers and connecting pipes and pipe fittings. How to select and classify materials is also very important. The copper branch pipes of air conditioner accessories can be divided into shaped pipes and round pipes according to their shapes. And shaped pipes can be divided into elliptical pipes, rectangular pipes, triangular pipes, hexagonal pipes, drop-shaped pipes, outer square inner round pipes, spiral pipes, inner rib pipes, outer rib pipes, etc. Different refrigeration and air conditioning systems will have different requirements for copper pipes.

1. Processing technical requirements for copper branch pipes of air conditioner accessories

The pipe processing of copper pipes shall be carried out according to the design drawings, and the shape and size shall meet the design requirements.

The diameter change at the fracture shall be within 2% of the standard diameter of the copper pipe, and the fracture shall not have flash or burrs.

The pipe fittings shall be degreased, decontaminated, free of copper chips, and the inner and outer surfaces shall be smooth, without oil stains, scars, or oxide scale.

The welding process must be nitrogen-protected, and after welding, the inside must be blown clean with 2.8~3.0MPa dry compressed air.
