Copper Pipe Fittings 90 Degree Elbow Air Conditioner Elbow Fittings
Manufacturing Process and Surface Treatment
● Manufacturing Process: Common processes include die-casting molding, forging process, etc. The die-casting process has high production efficiency and high dimensional accuracy, while the forging process makes the internal structure of the elbow dense and with higher strength.
● Surface Treatment: Usually, it undergoes surface treatment processes such as polishing and electroplating, making the internal and external surfaces smooth without burrs, improving the appearance quality and reducing the resistance during fluid transportation.
Application Fields
● HVAC System
● Water Supply and Drainage System
● Other Fields: It can also be used in the electrical system to protect and guide wires and cables, as well as in some industrial pipeline systems, etc.

Product advantages
1. The material of the red copper fittings is red copper, with a copper content of 99.9%, which makes it perform well in electrical conductivity and can also quickly transfer heat. It plays a key role in equipment such as heat exchangers and radiators, maintaining a suitable temperature environment.
2. Copper joints are highly durable, capable of withstanding high pressure and temperature changes. They maintain good stability in damp and corrosive environments and are not easily corroded.
3. With humanized design, the installation process can be easily completed without complex tools or professional techniques. Its material is highly flexible and can be quickly fixed by welding process, adapting to various pipe specifications. The interface of the accessories is precisely ground and has excellent sealing performance. Whether it is a household plumbing renovation or an industrial piping system, it can be installed and used immediately, taking into account both high efficiency and reliability.
In conclusion, with its outstanding performance, rich functions and unique features, red copper fittings have become an indispensable part of many fields. We are committed to providing you with high-quality red copper fittings and fully meeting all your needs.
