Below is a list of Copper Pipe manufacturers from Houston, Texas. Copper pipes are tubular sections or hollow cylinders fabricated using the nonferrous mineral copper or one of its alloys used for the transport of both liquid and gaseous process streams. The cross-section of most pipes is round, though square, hexagonal, octagonal or otherwise shaped pipes may also be found. Copper pipes in particular are well suited to conditions which may require additional shaping and forming as the metal is soft and malleable.
