A copper pipe is a reddish-brown metal tube used in plumbing, heating, refrigeration, and electrical systems for its excellent thermal and electrical conductivity, corrosion resistance, and malleability. These pipes are durable, non-toxic, and naturally antimicrobial, making them a preferred, long-lasting, and efficient material for transporting liquids and gases. They come in standard sizes and wall thicknesses, with different types like K, L, and M offering varying degrees of durability for diverse applications, including hot and cold water supply, drainage, and HVAC systems.
