Almost all graphite heat exchangers can be repaired and Louisville Graphite has repaired hundreds of units. Our philosophy is not to simply plug tubes or holes resulting in reduced heat transfer area. We have specialized testing techniques to determine leaks and porosity beyond those used throughout the rest of the industry. This permits us to provide accurate firm price proposals prior to beginning work.

All of our repaired or reconditioned units are re-impregnated. We thoroughly clean all units and repair cracked blocks, tubesheets and domes. In addition, all gasket surfaces are re-machined to insure proper sealing. We also supply all new gaskets, packing and bolting. All units have an exterior coating applied prior to shipment.

Repairs to the steel shell or other components can be done in-house. If repairs or modifications are required to A.S.M.E Code covered components, these can be done under A.S.M.E Code/ NBIC pressure vessel and repair obligations.
