Benefits
Protection of tube metal by polymer coatings will prevent oxide formation on your tube wall, extending life and eliminating unplanned maintenance of tube leaks. Coating can be used to protect against aggressive acid and alkaline.
Polymer coatings will reduce the surface tension of even a new tube by factor of 50; this inhibits the ability of fouling to attach to the tube wall, and eliminating cleaning cycles.
Over 70% of total heat transfer resistance for heat exchanger tubing is boundary layer fluid film and fouling. Removal of fouling and reduction of boundary layer drag of the exchanger enhances flow profile of the tube wall for the operational life, increasing heat transfer.
The sleek properties of high performance coatings substantially reduce tube wall friction, or boundary layer drag. Reducing drag can increase flow rates up to 80%, pressure differentials have been reduced by 50%. Without flow degration from corrosion and fouling these values remain constant.

Exchanger Tube Id Coating
Thin-film exchanger coatings have proven to mitigate fouling and corrosion that reduces asset life and cause unplanned shutdowns. Fouling leads to reduced heat transfer and production bottlenecks, increased maintenance; tube corrosion risks the integrity of exchanger mechanical performance and plant safety.
Tube Id Coating
An advanced two part 100% solids epoxy coating designed for high temperature immersion service in cooling water, hydrocarbons and process streams. This coating is an organic/inorganic hybrid with prior mechanical performance; resistant in cooling water steam services to 365°F (185°C) and excursions to 400°F (204°C). Applied to 8-14 mils total DFT.
An ultra-low DFT ambient-cure coating system designed for high-temperature fouling services; possesses excellent hydrophobic & oleophobic properties, anti-coking performance, resistant to thermal cycling and is suitable for services to 1200°F (648°C). Ideally suited for heat exchanger tubes, plate & frame exchangers. Applied to 20-40 microns total DFT.
Shop applied, bake catalysed, suitable for all cooling water services, hydrocarbons, salt solutions and solvents. Immersion resistance to 365°F (185°C); applied to 7-10 mils total DFT.
Shop applied, bake catalysed thermo-melts; superior resistance in chemicals, solvents and acids. Immersion resistant to 500°F (260°C). Applied to 8-14 mils DFT.
A polymer surface treatment; omniphobic (water and oil repellant) nanocomposite surface treatment that creates a slick surface. Applied to 50 mils; water and product services to 400F (204°C).
Coating for Fixed Equipment
An advanced two-part 100% solids epoxy. It is a high build coating that can be applied by brush or roller in one coat to repair and protect steel surfaces in wet/ immersion environments while still providing excellent corrosion resistance.

Exchanger Cleaning
Curran International’s patented dry grit blast tube ID cleaning process has revolutionised how clients clean their tubes in preparation for Non-Destructive Evaluation (NDE). Compared to conventional tube cleaning, Curran cleaning offers predictable results, eliminates cleaning rework, and promotes high integrity inspection data collection. Air coolers, shells & tube exchangers can be cleaned in situ; a dust abatement system ensures containments are vacuum-tight. Curran is experienced with process air coolers, SRU reactors, boilers and condensers, all metallurgies and U tube exchangers. Technicians visually confirm cleanliness, eliminating cleaning rework.
