Copper Pipe

Copper Pipe

Copper pipes are made from high-purity copper or copper alloys through an integral forming process, belonging to the category of seamless pipes. They possess excellent thermal conductivity, electrical conductivity, corrosion resistance, and good ductility and malleability.  Widely used in water transportation and refrigerant transmission, they are found in piping and heat dissipation components across various industries, including construction, HVAC, and electronics.  Thanks to their reliability, safety, durability, and ease of shaping, copper pipes have become one of the most commonly used and preferred materials in modern water supply and HVAC systems.

Copper Pipe Dimensions

Common size range for copper pipes: 6–108 mm
Small diameters are commonly used in air conditioning, refrigeration, and gas systems: 6, 8, 10, 12, 15 mm
Medium diameters are commonly found in plumbing and HVAC systems: 22, 28, 32 mm
Large diameters are mostly used in industrial and heat exchange equipment: 54 mm and above

In the refrigeration industry, imperial sizes are also widely used, such as 1/4″ (6.35 mm), 3/8″ (9.52 mm), 1/2″ (12.7 mm), 5/8″ (15.88 mm), and the wall thickness generally ranges from 0.6 to 4.0 mm depending on the application.
