Stainless steel and carbon steel
(OP)
Good morning Gents,
Is there any code that we can refer to which states "stainless steel material shall not be in direct contact with carbon steel"
Your response is highly appreciated.

Welding SS plate to CS plate for grounding lug is usual for the tank.
I have a tank with carbon steel flange inside the tank.
This nozzle will be connected to another flange and pipe which both are SS.
The bolt and nuts is SS. Between CS flange and SS flange I have graphite gasket.
The product is water but also there is small percentage of oil.
The stainless steel bolt will contact directly to CS flange. Is there any problem ?
RE: Stainless steel and carbon steel
Given the information in your second post, no there is not one specific rule that states you can't have CS and SS in contact. I've seen plenty of SS valves flanged up into CS systems. Just know that your CS is going to show the effects of the corrosion faster.

In the tank temperature indicator is SS flange type and connected to CS nozzle with CS bolts and nuts. But someone mention to me we will need insulation kits for these bolts and nuts.

Actually it is not pure water. There some small percentage oil.
