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.
Copper water tube is a seamless, almost pure copper material manufactured to the requirements of astm b 88 - standard specification for seamless copper water tube, of three basic wall thickness dimensions designated as types k, l, and m. Type k is the thickest and type m is the thinnest with type l being of intermediate thickness. All three types of tube are manufactured from copper alloy c12200 having a chemical composition of a minimum of 99.9% copper (cu) and silver (ag) combined and a maximum allowable range of phosphorous (p) of 0.015 % - 0.040 %.
Seamless copper tube manufactured to the astm b 75 - standard specification for seamless copper tube may be either round, square, or rectangular and is suitable for general engineering applications. It may be manufactured from any one of the following alloys: c10100, c10200, c10300, c10800, c12000, or c12200 unless specified otherwise on the original contract or purchase order.
Tubes meeting this standard may be furnished in any of several tempers (h55, h58, h80, o60, or o50) ranging from light drawn (usually limited to round tubes) to light annealed. It is the responsibility of the purchaser, when ordering, to provide the requirements for alloy (uns#), temper, dimensions (diameter, wall thickness, or distance between parallel surfaces), form (straight lengths or coils), and total length or number of pieces of any particular size. It is this requirement that forces this tube to be a special order tube and not a standard stocked material.
It is usually limited to use in specific manufacturing processes or production line type applications.
