Question:

What is the difference between a carbon block and graphite block?  

Answer:

People use these terms interchangeably, possibly because graphite is highly crystalline form of carbon.  The m Save & Exit ore correct term for the heat transfer material in your heat exchanger is graphite.


Question:

What is used to fill the voids in a piece of raw graphite?

Answer:

Graphite is most commonly impregnated with phenolic to make it impervious to fluids and useful as a heat transfer material.  Less frequently, teflon or even silicon carbide can be used for highly corrosive or erosive process fluids.


Question:

Are there different types of graphite tube?

Answer:

Yes.  There are three different types of impervious graphite tubes currently used in the chemical process equipment industry; Resin bonded, carbon bonded graphite, and fully graphitized. Each type has specific characteristics and cost implications that should be taken into consideration for each specific application.


Question:

Is there an advantage to using a monolithic tube over a joined tube?

Answer:

In general, No. When done properly, the cement joint is always stronger than the actual tube; just as in a metal weld when done properly. The same phenolic resin cement and basically the same joining method is used to connect the tubes to the tube sheets. Therefore, if the shell and tube design is appropriate for the process conditions, a monolithic tube offers no advantage in strength or operational life when compared with a joined tube.
