Description
Hardfacing Overlay Pipe is manufactured by depositing
chromium-rich, abrasion-resistant materials on the mild seamless
pipe or welding pipes, using a traditional arc welding process. The
wear pipe is available with double or multiple overlay passes. And
it can be fabricated as square-to-round transitions, elbows, T or
Y- shaped.
The CCO pipe is designed with extreme wear capabilities for working
in many applications: mining, cement, oil sands, dredging,
recycling and steel production industries.With either a
circumferential or longitudinal weld deposition.

Advantages
- Wear Resistance: Chromium carbide overlay tubes are highly
wear-resistant due to the presence of a hard and durable chromium
carbide layer on the inner surface. This layer provides excellent
protection against abrasive and erosive materials, extending the
lifespan of the tube.
- Hardness: The chromium carbide overlay layer in CCO tubes provides
exceptional hardness. It typically has a hardness rating of 55-65
HRC (Rockwell Hardness Scale), making it highly resistant to
penetration and deformation.
- Corrosion Resistance: Chromium carbide overlay tubes have good
resistance to various corrosive environments. The chromium carbide
layer acts as a barrier against corrosion, preventing the base
material from coming into contact with corrosive substances.
- Impact Resistance: CCO tubes exhibit excellent impact resistance,
making them ideal for applications where high-velocity particle
impact is a concern. The hard chromium carbide overlay layer helps
absorb and dissipate the energy generated by impacts, reducing the
risk of damage.
- Versatility: Chromium carbide overlay tubes can be manufactured in
various sizes, shapes, and configurations to suit specific
application requirements. They can be used in industries such as
mining, cement, power generation, steel, and many others.
- Easy Installation: CCO tubes can be easily installed using welding
techniques. They can be welded onto existing structures or
equipment, providing a cost-effective solution for wear protection.
- Customization: Manufacturers can tailor the thickness and
composition of the chromium carbide overlay layer to meet specific
wear resistance needs. This allows for customization based on the
severity of the wear environment.
