For twisted tubes with the same inner diameter, the thickness of ferrous metal is not required for copper tubes. When installing, the copper pipe has the advantages of lower transportation cost, easier maintenance and smaller space occupation. Copper can change its shape. Because the copper tube can be bent and deformed, it can often be made into elbows and joints. Smooth bending allows the copper tube to be bent at any angle.

Copper tube is light in weight, good in thermal conductivity and high in low-temperature strength. It is often used to manufacture heat exchange equipment (such as condenser). It is also used for assembling low-temperature pipeline in oxygen production equipment. Copper pipes with small diameter are often used to transport liquid under pressure (such as lubrication system, oil pressure system, etc.) and pressure measuring pipes used as instruments.
