Copper pipe is almost pure copper manufactured to the requirements of ASTM B 42 - Standard Specification for Seamless Copper Pipe, Standard Sizes. It may be manufactured from any of five (5) copper alloys (C10200, C10300, C10800, C12000, C12200) that all conform to the chemical composition requirements of alloys containing a minimum of 99.9% Copper (Cu) and a maximum of 0.04% Phosphorous (P). Available sizes are 1/8" to 12" diameters in regular wall thickness and 1/8" to 10" in extra strong wall thickness. The standard length for copper pipe is 12 feet. Copper pipe is suitable for plumbing, boiler feed lines, refrigeration and for similar purposes.
Joints in seamless copper pipe can be threaded, flanged or brazed to fittings of the appropriate joint configuration.
Wall thickness of copper pipe varies with the pipe schedule - the four common standards are named K, L, M, and DWV (Drain/Waste/Vent - non-pressurized), from thickest to thinnest.
