Wrought wrot copper alloy fittings used for drainage waste and vent applications with solder joints are manufactured to the requirements of ansi asme b16 29 wrought copper and wrought copper alloy solder joint drainage fittings dwv.
Copper fitting standards.
Astm b 251 standard specification for general requirements for wrought seamless copper and copper alloy tube covers a number of general requirements common to many wrought copper products.
The listing of standards is grouped under two sections.
In medical gas systems this prevents contamination of the gases used in healing and maintaining life.
Fittings manufactured to this standard are to have a copper cu content of not less than 84.
The standard establishes specifications for wrought copper and wrought copper alloy solder joint seamless fittings designed for use with seamless copper tube conforming to astm b 88 water and general plumbing systems b 280 air conditioning and refrigeration service and b 819 medical gas systems as well as fittings intended to be assembled with soldering materials conforming to astm b 32 brazing materials conforming to aws a5 8 or with tapered pipe thread conforming to asme b1 20 1.
Cleanliness for copper tube and fittings that are used for specific applications like medical gas astm b819 and hvacr systems astm b280 additional cleanliness requirements are included in the standards to ensure that the interior tube surface does not introduce any contaminants that might interfere with the safety or operation of the system.
Copper copper alloy tube and pipe.
A few of these specifications are b 68 b75 b135 b466 and b743.
