[labnetwork] CDA and copper piping

[Beall, James A. (Fed)]

Hi Kevin,

The CDA piping in our fab is Copper pipe:


Seamless copper tubing, ASTM-B88, Type-K, Type-L, or Type-M as indicated. Joints:

• High temperature soldered: Use 1,000 degF solder.

No problems with contamination for our purposes.

Best,

Jim

Hello All,
Has anyone used copper piping for clean dry air lines.  If not what kind of problems would one run into if going this route?  Thanks for any insight that can be provided.


Regards,
Kevin
