Copper pipes are a type of hard pipe used for plumbing and other applications, such as HVAC systems, natural gas supply lines, and more: 

•  Uses
  Copper pipes are commonly used for water supply lines and refrigerant lines in HVAC systems. They are also used for natural gas supply lines, boiler feed lines, and more. 

• Benefits
  Copper pipes are durable, corrosion resistant, and can withstand a range of temperatures. They are also non-toxic and don't contaminate water. 

• Types
  The most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. 

• Installation
  Copper pipes are malleable and lightweight, making them easy to install, even in complex systems. 

• Appearance
  Copper pipes have a clean finish and straight lines, making them a good choice for exposed installations. 

Copper pipes are used for a variety of purposes, including:

• Water supply and distribution: Copper pipes are used to deliver clean, safe water for drinking, cooking, washing, and more. Copper is nontoxic and resistant to corrosion, which ensures that water remains safe to drink. 

• HVAC systems: Copper pipes are used for refrigerant lines in air conditioners and heat pumps. Copper's ability to handle high temperatures and pressure variations makes it ideal for maintaining reliable cooling and heating performance. 

• Natural gas supply lines: Copper pipes are a safe and reliable choice for natural gas supply lines because they are resistant to fire and extreme temperatures. 

• Other mechanical systems: Copper pipes are used in a variety of mechanical systems, including underground water and gas services, drainage and vent systems, fuel-oil systems, and oxygen systems. 

• Medical-gas systems: Copper pipes are used in non-flammable medical-gas systems.

• Automotive and truck radiators: Copper pipes are used in automotive and truck radiators. 

• Hydraulic lines: Copper pipes are used in hydraulic lines.

• Food and beverage industries: Copper pipes are used to carry process fluids for beer, spirits, cane sugar refining, and other food processing operations. 

Copper pipes are malleable, lightweight, and come in a wide range of diameters and wall thicknesses. They can be joined using flare connection, compression connection, pressed connection, or solder.
