By the end of this guide, you’ll be able to decide where to get your CCO pipes from!

Knowing What Chromium Carbide is

What’s the first thing you think of when you hear chromium carbide?

Raw form of chromium carbide (non-powder form)

In reality, chromium carbide is a compound made up of parts of chromium and carbon. You can distinguish it because it’s an extra hard compound that is corrosion and abrasion resistant.

You can use it for many things; but, the most effective use it has is to serve as a coating for some parts and components.

Difference Between Abrasion and Corrosion Resistance in Overlay Pipes

Both are types of wear, which can damage parts or components of your machines.

These pipes are resistant to abrasion and other similar types of friction (inside and outside)

But what are their differences when it comes to resistance and some other properties?

You can define abrasion resistance as the ability to resist being worn out by abrasion (friction or rubbing).

It can happen when a material runs on another material; or when grit, dust, and other particles are trapped up and moved against the material.

Corrosion, on the other hand, is the type of wear that refers to chemical reactions or oxidation. Therefore, you can easily define corrosion resistance as a material’s ability to resist rust; or to resist being oxidized.

Stainless Steel Pipes vs. CCO Pipes

One of the biggest discussions is whether to use stainless steel pipes or CCO pipes.

Example of pipes made of stainless steel

How can you benefit from using each of them?

Here are some of the benefits of using stainless steel (ss) pipes.

Advantages of Stainless Steel Pipes

• Best Choice for High Temperatures
• UV Radiation Resistance
• Highly Durable
• Resistant Against Stains, Corrosion, and Rust
• Can Withstand Extreme Weather Conditions

Those are the benefits you get if you use stainless steel pipes. What about CCO or chromium carbide overlay pipes?

Advantages of CCO Pipes

• Chemical and Corrosion Resistant
• All Joints are Leak-Free
• Longer and More Durable Service Life
• Better and Faster Installation

Both are strong, however, not both of them have the same features and functionalities.

Your choice will most likely depend on the type of use you have for it.

What are CCO Pipes?

CCO is just a shorter term for chromium carbide overlay.

Chromium Carbide Overlay (CCO) Pipes

So, CCO pipes are also chromium carbide overlay pipes.

What are Induction Hardened Pipes?

Induction hardened pipes are a lot like CCO pipes.

These are induction hardened pipes that are hardened through magnetic means

But, they’re actually different because they’re not made out of chromium carbide. Instead, they’re hardened through martensitic transformation.

Hardened Steel Pipes vs. Steel Tubes

A lot of people think that pipes and tubes are all the same – they’re actually not.

Hardened Steel tubes in different shapes

Hardened steel pipes are tubular tools that are round that you use for distribution and transportation of gases and fluids.

9 times out of 10, they take the shape of a round object.

In contrast, hardened steel tubes can be round, rectangular, or oval. Unlike pipes, you can’t rely on tubes for distribution; you use it for connecting, linking, etc.

What is a Ceramic Lined Pipe?

Ceramic lined pipes are pipes with a lining of ceramic from within the inside or the exterior.

Pipe with an interior ceramic lining

You can use ceramic lined pipes in transporting materials that are abrasive and that can cause your pipes to undergo wear faster.

Its main use is for distributing materials that have high levels of friction and abrasion.

Features and Properties of CCO Pipes

Choosing to utilize chromium carbide pipes for overlaying is a win-win for you. It’s because of the following features of these pipes:

Large CCO pipes that are ready for distribution

Extreme Shock and Wear Resistance

Chromium carbide pipes are well known for their ability to resist wear. This can include:

• Corrosion
• Abrasion
• Erosion

In addition to that, you can also use them excellently in resisting shocks, cracks, and other forms of damages.

That doesn’t mean they’re invincible; CCO pipes just have higher resistance; which can withstand them longer.

Flexible and Versatile

Unlike regular pipes, you don’t have to worry about the industry you’re in.

Pipes that are made out of chromium carbide exteriors are flexible and versatile; you can use them whatever your industry or sector is.

Stronger and Longer-Lasting

At first glance, it might seem that CCO pipes are expensive. But, if you consider the fact that you’ll be able to utilize them more and longer, you wouldn’t worry about the cost!

The price might be as twice as expensive than regular and traditional pipes. But, you’ll be able to use them up to 5 times longer!

Those are just some of the features and advantages of utilizing chromium carbide overlay pipes.

Advantages of Using Chromium Carbide Overlay Pipes

Now that you know what the features of CCO pipes are, what advantages can you get from using them?

One big advantage of CCO pipes is overall strength

Some of the advantages considered by many include:

A chromium carbide overlay wear plate is a high performance steel plate designed to handle extreme abrasion, impact and corrosion in industrial application. Non alloying hard surfacing process for rebuilding the mild steel base with a special hard chromium carbide layer which is deposited by welding. This has excellent hardness and is able to withstand the abrasion of materials such as core and ore for a long lifetime, but also without any compromise on structural integrity and impact resistance that can be delivered with steel base. Utilized across a large number of industries including mining, cement, steel, power generation and in applications such as hoopers, crushers. These plates extend the operational life of equipment with reducing maintenance requirements thus benefitting the business directly. 

Understand the Material Composition

A chromium carbide overlay wear plate consists of a mild steel base and an overlay of hard surface that has high chromium carbide content (36% to 40%) on the top. To achieve hard carbides of around  HRC 55-65 within a ductile austenitic matrix, the overlay contains roughly 25-30% chromium. Other elements such as magnesium, silicon and boron also contribute to crack resistance and bonding. Due to its dual layer design, the system offers application specific characteristics from impact absorptive properties of a steel base to extreme wear resistance through use of chromium carbides, making it particularly well suited for mining and heavy industrial applications.

Evaluate Hardness and Toughness Of CCO Wear Plates

Their medium level of hardness combined with a good main strength means that CCO wear plates are like white iron, resistant to sliding and showing little brittleness. Featuring a ductile steel matrix embedded with distinctive chromium carbide particles. The material combines outstanding wear resistance and antifracture properties. It is primarily due to the hard carbide that provides chromium hardness, which makes the material resistant to scratching by abrasive materials such as ore and slag. In the meantime the stronger steel substrate absorbs mechanical shocks so that cracks do not spread. The result is a durable material for harsh wear environments, such as mining and cement industries.

Determine the Optimal Thickness

The CRC Wear Plate and clad plate are ideal for extreme abrasion, such as high impact, heavy rock abrasion. The most cost effective protection from light to moderate wear, It is a 3 – 5 mm overlay on a 10-12 mm steel base. Highly abrasive environments 6-12 mm overlay + 20-55 mm base stand up well over time. Too much material might cause cracking or lack of weldability, too little will burn through prematurely. Wear simulations, field trials and industry standards are used as a baseline of what to design while also taking into account that the certain components like bearings can even be fulfilled by putting in less lubricant.

Application-Specific Requirements

Chromium carbide overlay Wear Plates can be made to suit any specific application in various industries. In mining, thick overlays severely wear from ore and slag sliding abrasion, while heavy bases resist high impact loads. Cement plants used for a medium thickness overlay for clinker and raw material handling, with erosion resistance being the priority. Application in power generation concentrates on corrosion resistance in FGD systems and a coating that adds more chromium can be applied over the base layer. Customization options include material hardness as well as overlay pattern and weldability to fit ideally with the customer’s operations and extend service life in application. 

Conduct Material Testing and Certification

In Chromium carbide overlay wear plates the material testing and certification standards help you operate under assured performance and conduct. Primary Tests are hardness tests for verification of overlay hardness, metallographic analysis to assess the distribution and bonding integrity, followed by impact tests for checking toughness. KOOL will pass abrasion resistance testing according to ASTM G65 or DIN Quality checks including ISO , ASTM A514 and EN Non Destructive Testing. Detection of defects, MTRs with complete traceability for chemical composition and mechanical properties ensure that the plates are in front of application requirements in mining and heavy industries. 

Consider Surface Finish and Coating

Surface Finish and Coating integrity are vital for enhancing the life of chromium carbide overlay wear plates. The ground or machined overlay surface provides a smooth finish for non-stick and no material buildup in applications such as chutes or hoppers. More aggressive applications may require coatings such as epoxy or ceramic-containing sealers to enhance resistance to corrosion. Crack free weld deposited overlay also must have uniform distribution of carbide to help prevent delamination. PWHT is necessary to temper the steel allowing the weld to be stress relieved, helping coating adhere and coating’s longevity. Service propagation is further improved by perfect surface preparation and finishing in highly abrasive industries such as mining.  

Conclusion

Chromium Carbide Overlay Wear Plates provide a perfect combination of hardness, toughness and wear resistance involving in high abrasive application such as mining and iron manufacturing. The Wear face features a hard chromium carbide overlay, which is supported by the base of impact and erosion resistant steel. Thickness finishes and certifications can be mixed to provide a specific solution correlated to the need of operation. Even more, these coatings are continually tested for quality under extreme conditions and are to be treated as durable as possible during normal use. By processing the material, thickness and coatings of CCO plates they can help reduce downtime and maintenance costs for end users producing them a cost-effective solution for highly abrasive environments.
