Whertec Europe Tube Armor

Tube Armor®is an advanced high emissivity ceramic coating, specially formulated to provide erosion resistance and corrosion protection while increasing heat transfer and thermal efficiency. The coating is a high solids system which is applied as a stand-alone dry film at thicknesses up to 0.5 mm. It is thermally conductive and bonds extremely well to properly prepared steel substrates. Tube Armor® is also applied over our ChromeCladTM thermal spray coatings.

Based on Kirchhoff’s law of thermal radiation, the absorptivity of a given material is equal to its emissivity. A higher value means that the surface has a better ability to absorb the heat. A perfect black body that absorbs all the thermal radiation coming towards it has a coefficient of 1, while a polished metallic surface has a very low absorptivity as most of the radiation is reflected away. Tube Armor® has the capacity to absorb thermal radiation hitting its surface and transfer it towards the steam to improve the thermal efficiency of the boiler.

A durable ceramic coating

Upon curing, TubeArmor®becomes a durable ceramic coating that provides protection to boiler tubing up to 900°C and can withstand thermal cyclic conditions up to 1000°C. It is not just the technical features of TubeArmor® that makes it a superior choice for preventing slag build up. Whertec Europe’s thorough and detailed application and quality control procedure ensures optimum results. It includes:

  • Advanced equipment technology
  • Trained and experienced personnel
  • Detailed application procedures
  • Quality control and assurance
  • Detailed on-site documentation and reports

Inspection teams benefit with better visibility on coated surfaces thanks to Tube Armor’s® distinctive green color, designed to offer high-contrast against even small amounts of surface deposits.
