In industries where pipelines play a crucial role, ensuring their efficiency and durability is of utmost importance. One effective solution that can significantly boost these aspects is cladding. Pipeline cladding is applying a protective layer to the exterior of a pipe. We can do this for a variety of reasons, including to improve efficiency, corrosion protection, durability, and aesthetics.
In this comprehensive guide, we will explore what pipe cladding is, its power, its benefits, and how it can revolutionize the performance of pipelines.
Understanding Pipe Cladding
Pipeline cladding is a process that involves the application of a protective layer to the exterior surface of pipelines. This layer, made of materials that resist corrosion, protects the pipelines from environmental factors and makes them last longer.
Furthermore, welders usually think of surface hardening as a punishment, but this welding process serves an essential purpose. The most common application is to rebuild worn-down contact surfaces on heavy equipment.
In addition to creating a hard surface over a malleable substrate, surface hardening also creates a corrosion-resistant surface over a structurally stable underlayment. However, in the case of an interior pipe surface, this process is even more critical.
Additionally, to prevent corrosion, weld overlay cladding can resist extreme alkalinity or acidity. A smooth, nonporous surface can also improve product flow. Cladding is, therefore, critical to creating cost-effective process piping. In addition, manual welding is highly challenging for this type of internal pipeline cladding process.
Furthermore, power generation, petrochemical processing, biopharmaceutical processing, equipment manufacturing, water purification, and many other strategic industries require efficient automated cladding methods to manufacture equipment and complete projects. Moreover, you can determine future product manufacturing timelines based on the weld overlay process you choose.
Most Common Methods of Pipeline Cladding
The most basic method of cladding involves simply bonding two dissimilar metals together, though they can be very different in composition. The use of cladding for pipes is widespread. Here are a few of the more common techniques:
Thermal Spray Cladding
Thermal spray cladding utilizes high-velocity oxygen-fuel or electric arc systems to deposit protective coatings onto the pipe’s surface. However, we know this technique for its versatility and ability to handle complex geometries.
Coextrusion
Pushing molten or near-molten metal through a circular mold creates pipes. The process of coextrusion simultaneously extrudes the exterior pipe and its liner.
Hot Rollers
Using a set of hot rollers, we rolled together the base metal and the cladding alloy to bond the base metal and cladding alloy. Usually, the base metal is steel, and we create the clad pipes by curling it.
Explosion Bonding
Explosion bonding is one of the most exciting ways to clad pipes or pressure vessels. Cladding is best to line steel pipes and vessels, and skilled technicians carefully place calculated explosive charges on top. The explosion bonds the pipe and cladding together when the manufacturing crew sets off the charges.
Powder Metallurgy
Powder coatings are similar to those used to protect furniture and car underbodies from moisture and corrosion. It involves coating the interior surface of the pipe with powdered material melting it with heat, electricity, or lasers.
Weld Overlay
A similar process to surface hardening heavy machinery, weld overlay cladding involves creating overlapping welds along pipe interior surfaces. There may be a need to machine the interior surface later, but some automated welding techniques eliminate this need.

Benefits of Pipeline Cladding
Enhanced Corrosion Resistance
Corrosion is one of the primary challenges that a pipeline can face. Cladding provides an excellent defense mechanism against corrosion, preventing damage and minimizing the need for frequent repairs or replacements.
Increased Strength and Durability
Pipeline cladding, which adds a layer of robust and durable materials, significantly enhances the overall strength of pipelines. This allows them to withstand harsh operating conditions and external pressures, ensuring long-term reliability.
Improved Thermal Insulation
In specific applications, maintaining a consistent temperature within pipelines is crucial. Cladding for pipes can provide effective thermal insulation, minimizing heat loss or gain and optimizing energy efficiency.
Durability
It can also help to extend the life of a piping system by protecting it from the elements. Chemical plants and refineries, which face harsh environments, are susceptible to this issue.
Aesthetics
You can also use it to improve the appearance of a piping system. This can be important for pipes that are visible in public areas, such as those found in hospitals and office buildings.
Efficiency
This can help to improve the efficiency of a piping system by reducing heat loss. This is especially important for pipes that carry hot fluids, such as steam or hot water. Furthermore, cladding can also help to reduce condensation, which can lead to corrosion and other problems.

Application of Pipe Cladding
You can apply cladding to pipes of all sizes and materials. The most common application is for pipes that carry hot fluids, such as steam or hot water. However, we can also use cladding for pipes that carry cold fluids, such as chilled water or chemicals.
We can also apply cladding using a liquid coating material. We typically apply this coating to the pipe using a spray gun or brush. Moreover, we can make liquid coating materials of a variety of materials, including paint, epoxy, and rubber.
Here are some comm applications of cladding:
Oil and gas industry
The most common use of cladding is to protect pipes from corrosion and erosion in harsh environments, such as those found in the oil and gas industry.
Petrochemicals
Petrochemical plants use pipeline cladding to protect pipes from corrosive and flammable chemicals.
Water and Wastewater Treatment
Water and wastewater treatment facilities use cladding to protect pipes from corrosion and abrasion.
Power Generation
In power plants, cladding protects pipes from corrosion and high temperatures.
Mining
In mines, pipeline cladding protects pipes from corrosion and abrasion.
Food and Beverage Processing
In food and beverage processing plants, pipe cladding protects pipes from corrosion and bacteria.
Pharmaceutical Manufacturing
Pharmaceutical manufacturing facilities use it to prevent corrosion and contamination.
Electronics Manufacturing
Electronic manufacturing facilities use pipe cladding to protect pipes from corrosion and contamination.
In addition to these industrial applications, we can use it in a variety of other settings, including residential, commercial, and institutional buildings.
Pipe Cladding Materials
We can use a variety of materials for pipeline cladding. The most common materials include:
Insulation
Insulation is used to reduce heat loss and improve efficiency. There are many different types of insulation available, including fiberglass, rockwool, and foam.
Foam
Foam is also used to reduce heat loss and improve efficiency. It is also lightweight and easy to install.
Reflective materials
Reflective materials can be used to reduce heat gain and improve efficiency. The material typically includes aluminum foil or Mylar.
Metal
Metal is used to protect pipes from the elements and extend their life. The most common metals used for cladding include stainless steel, aluminum, and galvanized steel.
Plastic
Plastic is also used to protect pipes from the elements and extend their life. It is lightweight and easy to install, but metal is more durable.
Concrete
Concrete is used to protect pipes from the elements and extend their life. It is very durable, but it is also heavy and difficult to install.
