China Factory Wholesale Copper Straight Pipes for Plumbing, Refrigeration, and Building Use Seamless/ Red Copper Pipe

Product Description

Product Description

Copper tube and copper coil are two common forms of copper processing products, which are widely used in electric power, construction, machinery, electronics and other industries. The following is their detailed introduction and differences:

1. Copper Tube/Pipe

    Definition

   Copper tubes are hollow, circular cross-sectional or other shapes (such as rectangular, oval) straight bars or coils, usually made of pure copper (purple copper) or copper alloys (such as brass, bronze).

   Features:

Corrosion resistance: Anti-oxidation, suitable for transporting water, gas or chemical media.

Thermal conductivity/electrical conductivity: It is often used in heat exchangers and refrigeration equipment (such as air conditioners and refrigerators).

Plasticity: Easy to bend, weld and process.

Type: Divided into hard (rigid) and soft (flexible) copper tubes.

   Common use:

- Construction: water supply pipes, HVAC systems.

- Industry: refrigeration equipment, heat exchangers, oil pipelines.

- Electronics: wire protection sleeve.

    Specification:

- Outer diameter: commonly 3mm~200mm, wall thickness 0.5mm~10mm.

- Standard: conform to ASTM B68 (seamless copper tube), GB/T 18033 (Chinese standard), etc.
