Is an isolation gasket required between the stainless steel pipe and the heat tracing pipe (carbon steel)? The heat tracing pipe (carbon steel) has been painted! If a spacer is to be used, what material should it be made of?
Yes, there is a potential difference between stainless steel and carbon steel, and galvanic corrosion can occur under certain conditions. Asbestos rubber sheets are generally sufficient as isolation pads.
Don’t isolation pads need materials with good heat transfer properties?
At the points where stainless steel, alloy steel, aluminum, and galvanized pipes come into contact with carbon steel frames, insulating layers such as asbestos cloth, rubber, and asbestos rubber should be used. For further communication, you can add Chuan You.
There is no need to worry too much about heat conduction between the pipes, as the heat tracing pipe and the pipe being heated are wrapped together with insulating material.
