The standard shell and tube graphite heat exchangers comprises a steel shell enclosing a graphite tube bundle fitted with end covers. Because of the differences in their coefficients of thermal expansion, (steel expands 2-3 times as much as graphite) the differential expansion between the steel shell and the graphite tube bundle is taken up by the externally packed floating tube sheet.
Shell and Tube Graphite Heat Exchangers Our Impervite shell and tube heat exchangers are engineered for superior reliability and service life. Compared to other graphite heat exchangers, they offer exceptional performance and a low initial cost, resulting in an excellent lifetime return on investment.
