Heat Exchangers

Belzona provides a variety of solvent free metal repair composites and epoxy coatings for repair and protection of heat exchangers damaged by erosion and corrosion on areas such as tube sheets, water boxes, division bars and end covers. Our cold curing epoxy products allow for rapid, in-situ application minimising downtime whilst providing long-term erosion and corrosion protection. Belzona materials are excellent electrical insulators, which enables them to prevent galvanic corrosion by isolating the dissimilar metals used in heat exchangers.


Heat exchanger restoration

Heat exchangers can be repaired using cold applied metal repair composites and epoxy coatings that will not only rebuild heat exchangers’ components to their original profile, but also will:


  • Provide long-term erosion and corrosion resistance
  • Eliminate galvanic corrosion
  • Minimize downtime
  • Increase thermal conductivity
  • Provide high temperature resistance
  • Offer outstanding chemical resistance against a wide range of chemicals
  • Eliminate the need for hot work
  • Reduce expensive replacement costs
  • Extend equipment life



Metal repair materials frequently used to repair heat exchanger’s components such as tube sheets, flange faces, water boxes and end covers suffering from erosion and corrosion include Belzona 1111 (Super Metal), Belzona 1311  (Ceramic R-Metal) and Belzona 1121 (Super XL-metal), and . Additionally, we offer high temperature materials such as Belzona 1511 (Super HT-Metal) that can be used to rebuild heat exchangers operating at the temperatures up to 150°C (302°F).

Heat exchanger protection with epoxy coatings

Our metal repair composites are designed to be coated with a wide range of Belzona epoxy coatings to achieve long-term erosion and corrosion protection of heat exchangers. Our range of coatings include Belzona 1321 (Ceramic S-Metal),  specifically designed to provide erosion resistance in continuous immersion at temperatures up to 60°C (140°F) and Belzona 1341 (Supermetalglide), which is used when more detailed work is required or longer overcoating window is needed.

Other specialist coatings incorporating chemical, high temperature, erosion and cavitation resistance or a combination of these properties ensure Belzona has a solution for almost all service conditions.
