Preventive Maintenance

Preventive maintenance is used to protect your parts from abrasion, erosion, corrosion, cavitation and adhesive wear. The goal is to keep your assets in optimal condition and reduce unscheduled repairs, ultimely preventing breakdown. Wearfaced parts offer significantly enhanced service lifetimes over new unprotected parts. Castolin Eutectic performs preventive maintenance on boiler tubes, screws, rolls and much more.


Despite their industrial application and heavy-duty appearance, tubes require stringent care and maintenance. This is a result of slag – the fine particulates that build up on tubes to cause corrosion, erosion, leaks and other failures. Too much slag literally chokes a boiler by restricting airflow. Once this happens, the specified air-to-fuel ratio no longer applies, causing fuels to burn improperly. If the fuel in question has high mineral content, you also have the added safety challenges caused by clinker formation. Tube Armor helps prevent slag from depositing on tubes and boilers with a proprietary spray-on ceramic coating. It is a non-porous, non-reactive shield that resists ash, oxidation, erosion, iron sulfide corrosion, sulfur permeation and hazardous chemical byproducts. Tube Armor is applied on the prepared surface one coat at the time until the recommended thickness is achieved. The convenient spray-on delivery system allows us to cover up to 2000 square meters in a single day.
