Copper water tube is a seamless, almost pure copper material manufactured to the requirements of ASTM B *8 - 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 C****0 having a chemical composition of a minimum of *9.9% Copper (Cu) and Silver (Ag) combined and a maximum allowable range of Phosphorous (P) of 0.**5 % - 0.**0 %.
Seamless copper water tube is manufactured in sizes ¼" through *2" nominal. Types K and L are manufactured in drawn temper (hard) ¼" through *2" and annealed temper (soft) coils ¼" through 2" while type M is only manufactured in drawn (hard) temper ¼" through *2".
Seamless copper water tube of drawn temper is required to be identified with a color stripe that contains the manufacturer\'s name or trademark, type of tube and nation of origin. This color stripe is green for type K, blue for type L and red for type M. In addition to the color stripe the tube is incised with the type of tube and the manufacturer\'s name or trademark at intervals not in excess of 1½ ft. Annealed (soft) coils or annealed straight lengths are not required to be identified with a color stripe.
