INDIA LOSES THOUSANDS OF CRORES OF RUPEES DUE TO BOILER TUBE FAILURE!
A coating technology to prevent boiler tube failures due to external erosion, abrasion, corrosion & high-temperature oxidation.A Reliable boiler tube coating technology to stop boiler tube failures due to surface abrasion, corrosion.
WHAT IS THERMAL SPRAY?
Thermal spray coating is a general name for a combination of processes in which a wire/ powder is melted, either by fuel or electrical means, to its melting point, atomized by the usage of pressurized air & then moved onto the prepared component. The melted particles hit the prepared surface & fix instantly, create up layer upon layer to make a coating.
HOW THERMAL SPRAY CAN BE USED TO PREVENT BOILER TUBE FAILURE?
The thermal spray-on boiler tube coating technology to give high-temperature wear & corrosion protection coating on the boiler tubes. A broad type of coating materials such as mild steel or other metals or alloys is available. Therefore a proper coating can be utilized on the tubes to combat the specific queries without changing the tube material.
WHAT ARE THE BENEFITS OF THERMAL SPRAY TECHNOLOGY?
- Corrosion Protection
- Increase the life of the material.
- Give high performance.
WHAT ARE THE ADVANTAGES OF THERMAL SPRAY TECHNOLOGY?
- COLD PROCESS: Thermal spray is a cold process so there is no risk of distortion or change in any property of the tubes.
- PORTABLE EQUIPMENT: we have completely portable equipment to provide protective coatings on boiler tubes at the site.
- REDUCED DOWNTIME: Because of the high deposition rate, as compared to conventional welding, and instant solidification of the sprayed material the downtime is drastically reduced.
- HEAT TRANSFER: There is negligible loss of heat as compared with conventional shields or refractories because the coatings have high thermal conductivity, low thickness and are applied directly to the tubes.
- THERMAL EXPANSION: Coating can be tailored to equal its thermal expansion with that of the tubes.
- Localized REPAIR POSSIBLE: Special attention can be given to erosion/corrosion-prone areas by giving higher thickness or by using the premier quality coating. The coating may only be applied in selected areas.
- NO LIMITATION OF SIZE: Coating can be applied to the tubes already in place as well as to new tube assemblies prior to/after installation, without any constraint of size or length of the tubes.
