Features:

1. Copper is economical. Copper pipes are easy to process and connect, saving on material costs and total costs during installation. Stability and reliability help you save maintenance

2. Copper is light. For threaded pipes with the same inner diameter, copper pipe does not require the thickness of ferrous metal. When installing, copper pipe is low shipping cost, easy to maintain and save space.

3. Copper can be reshaped. Copper pipe can be bent and deformed, so it can be used in many cases as elbow or joints. Smooth bending allows copper tubing to be bent at any angle.

4. Copper is easy to connect.
