Copper pipes are made mainly of copper, typically containing more than 99% pure copper. They may also contain small amounts of other elements such as phosphorus to improve the material's strength and machinability. Copper pipes are available in various sizes and diameters, measured in inches or millimeters(mm). Common sizes include 1/2 inch, 3/4 inch, 1 inch, and larger, with corresponding nominal pipe sizes (NPS). Copper Pipe Weight, Dimensions Chart in mm, kg and inches is displayed below. Copper pipes come in straight lengths, coils, and as soft, flexible tubes. Straight lengths are applied for fixed installations, while coils and flexible tubes are applied where bending and shaping are required. Copper pipes can be joined using various techniques, including soldering, brazing, compression fittings, and push-fit fittings. Soldering and brazing involve melting a filler metal to create a strong, leak-resistant joint.
Copper Pipes are available in both hard and soft tempers, with the latter meaning that the tube has been annealed to soften it. Hard tubing is joined by capillary fittings. Soft tubing can be joined in various additional ways, including compression fittings and flaring. Both are manufactured as seamless constructions. Copper pipes are used in plumbing, HVAC, refrigeration, medical-gas delivery, compressed-air systems, and cryogenic systems. The weight, dimensions chart of Copper Pipes are given in PDF.
