How we produce clad pipe?

  • The wear pipe is mainly made by hardfacing technology, the mechanical part of the equipment is designed reasonably, the electric part adopts the key surface input data, which can be connected with other equipment and welding machine freely The walking speed can be adjusted at any time according to the need, the welding pass can be arranged automatically, the welding wire can be deposited continuously, the wire feeding is automatic, the swing speed and width of the welding torch can be set by yourself; In the welding process, the height of welding torch is automatically tracked by independent research and Development System to improve the overall efficiency.

Clad pipe transport and installation

  • Hardfacing wear-resisting pipe can be installed directly by welding. Because of the high resistance of the wear-resisting layer, it is very convenient to knock, cut, replace, repair and install the pipe at will when local scaling and blocking occurs in the pipe guide.

Cladding Pipe – The Ultimate FAQ Guide

Pipes have a crucial role in every industry there is. Industrial and manufacturing companies need strong, tougher, and wear-resistant pipes.

But pipes are usually just made from regular materials – how can you improve this?

In this guide, you will learn everything you need to know about cladding pipes. What it is, what it’s used for, and how you can take advantage of it.

What is Pipe Cladding?

Pipe cladding simply is the process of applying cladding material to a pipe.

Pipe Cladding

It usually is a metallurgical attachment of clad material to a pipe.

What is the Cladding Pipe Process?

Cladding Pipe Process

The general cladding pipe process is quite simple and easy-to-understand. It goes as follows:

  1. One or more metals are selected to be joined together
  2. You’ll join these metals by welding it to the surface of the parent material
  3. This process is done to improve the material in all angles and aspects

Where Can You Apply and Use Clad Pipes?

You can use cladded pipes mostly in certain situations and scenarios, where there is:

Clad Pipes Application

  • High Pressure
  • Dynamic and High Stress
  • High Levels of Corrosiveness and Abrasion
  • High Temperatures

In addition to that, cladding pipe is highly beneficial for certain industries like:

  • Mining Industry
  • Gas and Oil Industry
  • Manufacturing Industry
  • And Others

What are the Different Pipe Cladding Methods?

Pipe Cladding Methods

The different methods you can take in cladding pipe are:

Hot Rolling

It’s a process where the pipe is bonded with the clad by heating the base metal.

You would allow the base metal to pass through hot rollers, and thus, the hot rolling process.

Explosion Bonding

This process involves explosives and the process is simple:

  • The steel pipe would be lined with the cladding
  • Calculated explosives would be placed on the cladding surface
  • With heat and pressure combined, the explosion would bond the pipe and the clad together

Powder Metallurgy

In this process, you will use a layer of powdered material on the interior part of the pipe.

Then, you’ll melt the material via electrical currents, heat, lasers, or other mediums.


This process uses molten or near molten metal, creating extruded pipes.

Coextrusion means that the cladding pipe is made through both the liner and the exterior pipe at the same time.

Weld Overlay

Weld overlay is a process that is the deposition of materials to a surface or a parent material.

Weld Overlay Pipe

More often than not, you would use materials with the same properties as the workpiece. This enhances the base metal.

What is Overlay?

Overlay is the process of covering something up using coating material through welding.

In overlay, you ought to use metals with the same characteristics to that of parent workpiece.

Is Overlay the Same as Cladding Pipes?

No, weld overlay and pipe cladding are two different processes.

Overlay Not the Same as Pipes

They have the same goal, but you’d do each of them in a different manner.

Pipe cladding is the process of applying protective material over the surface of the base metal. The use of cladding is to deposit abrasion and corrosion resistant properties to the surface.

Weld overlay is a process of improving prudent properties of the base metal itself.

It is done by depositing metals with the same characteristics that of the parent material.

What is CRA Cladding?

CRA cladding is the type of cladding that uses CRA material to cover and protect the surface.

CRA Cladding

Short for corrosion resistant alloy, you would need CRA cladding if you aim for highly-corrosion resistant properties.

What are Clad Materials?

Clad materials are materials that fuse two or more metal types through bonding.

Clad Materials

These clad materials you can make will have unique properties coming from the metals used.

What is Pipe Lining?

Pipe lining is a process that you can do to restore pipes that have been subject to wear.

Pipe Lining

You can perform pipe lining by coating the pipes’ interior to create longer-lasting material.

Why is Cladding Pipes Important in the Oil and Gas Industry?

The oil and the gas industries are the industries that are most prone to corrosion.

Both industries deposit high levels of sulfur and carbon dioxide. Because of this, corrosion in their parts and materials is easy.

Oil and Gas Industry

If you’re in the business and you need to create more corrosion-resistant pipes, pipe cladding is the way to go.

Is Pipe Lining and Pipe Cladding the Same?

No, cladding pipes and lining pipes are not the same. They are two different methods that have different outcomes.

Pipe lining refers to a process where you bond a pipe and a line material.

Pipe Lining or Cladding

Pipe cladding is the process in which you would bond cladding material and a pipe.

The goal of the former is to withstand rough and absurd chemical environments.

Cladding pipes is used mainly to resist corrosion in high stress and high temperature environments.

What are the Advantages of Cladding Pipes?

Some of the pros or advantages of cladding pipes include:

Advantage of Cladding Pipe

  • Improved crack and wear resistance
  • It’ll be able to withstand extreme temperatures, pressure, and stress
  • Provides air and chemical pollution resistance
  • More workable with high heat

What are the Disadvantages of Cladding Pipes?

Disadvantage of Pipe Cladding
