Segregation of Materials

[weeeds]

Good Manufacturing Practice requires a fabricator to segregate materials such as stainless from carbon, in storge and at point of use.
Are there any International Codes that actually enforce such segregation? Does the ASME Code require this?
Thank you.

The ASME B&PV Code and most Codes and Standards do not provide guidance or detail on how to manage your Quality Program, which should include procedures for receiving inspection and ultimately handling material inventory. If you need guidance, look to accreditation bodies like ISO 9000.

Vidalia,

There is a "old-time" common practice in fabrication shops to keep wire brushes for carbon steel seperate from those of stainless.

The idea was to keep small carbon particles from becoming embedded into stainless and causing a "galvanic couple" that would corrode. (galvanic corrosion is a fuction fo both the electropotential and the relative surface areas)

With today's modern management and a plethora of MBAs, this simple practice has mutated into hysteria about "letting stainless touch carbon".....

Talk with a competent fab shop about thier practices an consult a good book on corrosion...

It is a good practice in general.

If you keep CS on the left, and SS on the right, when someone is in a hurry, they are less likely to pull from the wrong side.
