Description
Chromium carbide overlay pipe, also known as CCO pipe, is a type of
pipe used in various industries for wear and abrasion resistance.
It consists of a carbon steel pipe with a layer of chromium carbide
deposited on the inner surface.
The chromium carbide overlay is created through a welding process
known as hardfacing, where a mixture of chromium carbide and other
alloying elements is applied to the inner surface of the pipe. The
overlay forms a hard, wear-resistant surface that protects the pipe
from abrasive materials, erosion, and corrosion.

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.
Application
- Mining: CCO tubes are widely used in mining operations,
particularly in equipment such as slurry pumps, chutes, hoppers,
and conveyor systems. They provide excellent wear resistance
against abrasive materials like rocks, ores, and minerals.
- Cement Industry: CCO tubes are employed in cement plants to protect
equipment exposed to abrasive materials and high temperatures. They
are often used in applications such as cyclones, kiln feed pipes,
and coal mill ducts.
- Power Generation: CCO tubes are utilized in power plants,
especially in areas where coal, ash, or biomass is handled. They
can be employed in applications like ash handling systems,
pulverizers, and coal piping, providing wear resistance against
abrasion and erosion.
- Steel Industry: CCO tubes are used in steel mills and foundries to
protect equipment from wear caused by high-temperature processes,
abrasive slags, and molten metal. They can be applied in
applications such as blast furnace bellows, hot gas ducts, and slag
troughs.
- Chemical Processing: CCO tubes are suitable for applications in the
chemical industry where corrosive substances and abrasive materials
are present. They can be used in pipelines, reactors, and other
equipment to provide both wear and corrosion resistance.
- Pulp and Paper Industry: CCO tubes find application in the pulp and
paper industry, particularly in areas where abrasive materials like
wood chips or pulp are transported. They can be utilized in
applications such as chip handling systems, pulper hoods, and
piping.
- Recycling Industry: CCO tubes are used in recycling facilities to
protect equipment involved in the processing of metal scrap,
plastic, glass, and other materials. They provide wear resistance
against the abrasive nature of these materials.
- Aggregate and Quarrying: CCO tubes are employed in the aggregate
and quarrying industry to protect equipment such as crushers,
screens, and conveyor systems from wear caused by rocks, gravel,
and sand.
