Stainless Steel Piping
(OP)
Hello,
What is experience on 18" stainless steel pipe sitting on carbon steel support steel with U bolts around it. The pipe wall thickness is 0.25" carrying DNCG gas. Is that okay to let the pipe sit on carbon steel structure. Do we need posion pad? The pipe is at 200F.

Here's the chart the metals guys always hand me when I ask about galvanic corrosion:

In pipes using a SS clamp type guide with a lot of axial movement and/or vibration I've seen a lot of galling and wear with some metal loss. On heavier piping we use the roller type supports and depend on design to get vibration out. We use both SS and CS rollers.

You should use a shoe in case of hot insul. and wood or strong foam in case of cold insul.
