Impregtite Graphite Heat Exchangers

Standard shell and tube exchangers resistant to chemical attack from acids, alkalies, solvents and salts.IMPREG-TITE … as a material of construction combines graphite, one of the most chemically inert materials, unequaled in heat transfer characteristics, with a series of resins to give the engineer a new dimension in heat transfer design in this energy and environment conscious world.

 Corrosion Resistance Characteristics

IMPREG-TITE is virtually immune to thermal shocks and can typically handle difficult solutions such as hydrochloric, sulfuric and hydrofluoric acids, halogenated organics and aqueous salt solutions. ACS has accumulated considerable corrosion data on IMPREG-TITE and can provide to you the benefit of our extensive practical experience in handling difficult solutions. As a matter of policy, ACS may furnish suitable test coupons or a complete test unit for some applications involving combinations of difficult chemicals or proprietary intermediates.

 Thermal Characteristics

IMPREG-TITE impervious graphite is immune to thermal shock within its operating limits (340°F) and has a thermal conductivity of 1020 BTU/HR Sq. Ft. (°F/in.), 9 times stainless steel, 6 times Monel, 3 times tantalum and 2.2 times carbon steel! The maximum recommended operating temperature for IMPREG-TITE is 340°F.

 Design Characteristics

Because of superior corrosion resistance, lmpregtite does not require a “corrosion allowance.” Corrosive fluids are normally handled inside IMPREG-TITE tubes for easy cleaning. The corrosive fluid comes in contact with only IMPREG-TITE tubes, tube sheets and domes. Suitable gaskets are furnished on application. Shells are usually furnished in carbon steel for heating with steam or cooling with process water. However, they can be furnished in Haveg, FRP, rubber lined steel or stainless for handling two corrosives simultaneously.
