It’s most often used for supply of hot and cold tap water, and as refrigerant line in HVAC systems. There are two basic types of copper tubing, soft copper and rigid copper. Copper pipe is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance.

Copper pipe is used extensively to convey potable water in buildings and homes. Copper alloys are selected to convey many diverse fluids for the oil, chemical, process and marine industries. Copper tube’s second largest application is in air-conditioning and refrigeration systems; its fastest-growing use in is fire sprinkler systems and fuel gas distribution systems in residential and office buildings. Copper is used for plumbing tube principally because of its corrosion resistance, machinability and high level of heat transfer.
