Heat conductive and exchanger coating series

To improve the protection of a heat exchanger and its tube, CP Phenolics offers a specially developed heat conductive coating series. These coatings are heat conductive and can withstand large temperature fluctuations between -120°C and 220°C. The heat exchanger tube protection coating is extremely resistant to strong alkaline to acid media. Its most important features are:

  • Erosion protection
  • Corrosion protection

    Baked Phenol coating protects the plate of the Plate Heatexchanger

    Coated plateheatexchanger

  • Anti-fouling
  • Flow improvement

Depending on the type of exchanger we can apply the coating using:

  • Flooding technique
  • Tube lining technique
  • Immersion technique
  • Spraying technique

The process of a heat exchanger protection coating

Heat-cured phenol epoxy coating:

A heat exchanger is a very important part of the chain in a process, it is therefore essential to ensure reliability and optimum performance. To achieve this, a good conservation is required. Years of experience in the field learns us that our CP Phenolics® coating (phenolic epoxy coating) has outstanding characteristics in this matter.

CP Phenolics ® heat cured conductive coating achieves great value to customers thanks to high chemical resistance to aggressive media even in high concentration and high temperatures up to 220°C.
This coating prevents corrosion and fouling and incrustation in the tubes. Consequently, by applying the coating on a heat exchanger tube, optimal protection is guaranteed and operational costs are reduced. The heat conductivity remains constant with the result of better efficiency and allows a simple cleaning process.

Benefits of a coated shell tube

Treatment a heat exchanger’s shell tube with a CP Phenolics® coating will lead to:

  • Low resistance coefficient (maximum flow through the tubes)
  • Optimal heat transfer
  • High operational reliability
  • Extended lifetime of the heat exchanger

Application description

The coating is a thermosetting coating of minimum 3 layers. Every layer gets an oven treatment on a different time and temperature schedule. During the final polymerization session, the coating layers cross link with each other on molecular level. Derived from this, the coating offers high-end corrosion protection against all sorts of aggressive substances that lead to deterioration of the heat exchanger tube.

Cost reduction

The aforementioned cases ensure that investment and maintenance costs will be reduced. We therefore recommend not only to provide a protective coating on new heat exchangers but also those who are in actual use.

Example case Project BASF

Entry temperature of condensate: 98 – 103 °C, cooling water speed: 0.3 m/sec.
