Abstract

This specification covers seamless round and rectangular including square copper alloy tube in straight lengths. The following copper alloys are specified and classified according to their nominal compositions: UNS No. C22000, UNS No. C23000, UNS No. C26000, UNS No. C27000, UNS No. C27200, UNS No. C27400, UNS No. C28000, UNS No. C33000, UNS No. C33200, UNS No. C37000, and UNS No. C44300. The tempers of drawn tube shall be designated as light-drawn (H55), drawn (H58), and hard-drawn (H80). Light-drawn (bending) temper is used only when a tube of some stiffness but yet capable of being bent is needed. Drawn temper is for general purposes and is most commonly used where there is no specific requirement for high strength on the one hand or for bending qualities on the other. Hard-drawn temper is used only where there is need for a tube as strong as is commercially feasible for the sizes indicated. For any combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used. The tempers of annealed tube shall be designated as light anneal (O50) and soft anneal (O60). The tubes shall undergo mechanical tests such as tension test, Rockwell hardness test, and expansion test in order to determine certain properties such as tensile strength and hardness. A mercury nitrate test shall be done to detect and remove mercury vapor. Nondestructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well.

1.3 WarningMercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPAs website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law. (See 10.1.)
