What this product is designed to do
TubeArmor is a high-emissivity ceramic coating described by Castolin Eutectic for boiler tubing and heat-transfer surfaces. The brochure identifies erosion and corrosion protection and improved heat transfer as intended benefits; project suitability must be reviewed for the actual boiler conditions.
Product details
- High-solids ceramic coating; brochure describes standalone dry film up to 0.5 mm.
- Thermally conductive; bonds to properly prepared steel substrates.
- Can also be applied over ChromeClad thermal-spray coatings, as described in the supplied brochure.
- Emissivity coefficient in supplied brochure: carbon steel 0.34; TubeArmor 0.80 (ASTM E1933-99A).
- Temperature statements in supplied brochure: boiler tubing protection up to 900°C; thermal cycling up to 1000°C.
Key product points
- High-emissivity ceramic coating designed to resist erosion, corrosion and slag/ash deposits.
- The supplied brochure states a dry-film thickness up to 0.5 mm and emissivity coefficient of 0.80, compared with 0.34 for carbon steel under the stated ASTM E1933-99A reference.
- The brochure states protection of boiler tubing up to 900°C and thermal-cycle resistance up to 1000°C; verify the current product revision and site conditions before specification.
- Distinctive green finish provides contrast during inspection of coated surfaces.
Where to use
- Boiler water walls
- Nose arch and slope tubes
- Superheater and reheater tubes
- Burners, chutes and ducts
- Back-pass areas and air-preheater baskets
- Pulverised-coal, circulating-fluidised-bed, waste-to-energy and biomass boilers
- Waste-heat units
Practical checks before the job
- Map the boiler surface, tube material, deposit pattern, erosion/corrosion history and operating temperature profile.
- Inspect the substrate and determine preparation, access, outage window and any existing coating system.
- Confirm the current TubeArmor TDS/SDS, compatibility with the substrate or ChromeClad system, target film thickness and cure requirements.
- Have the application carried out under the manufacturer-approved procedure and quality-control plan by trained personnel.
- Document surface preparation, coating batch, application conditions, inspection and acceptance before returning the boiler to service.
Selection check: All technical values are transcribed from the supplied Castolin Eutectic TubeArmor flyer; confirm the latest TDS/SDS, boiler design limits, application method and supplier authorisation. Do not guarantee fuel savings, emissions reductions or service life.
