We all know that corrosion poses a silent yet formidable threat. No matter your industry, corrosion is the cancer that slowly disrupts your business. Whether in manufacturing or owning seamless tubes and pipes companies, you must deal with corrosion at some point.   

Now, seamless pipes are critical in many sectors. While they support the construction industry, these pipes are irreplaceable in automobile exhaust systems. Hence, as a manufacturer, you are responsible for ensuring these pipes do not succumb to corrosion. Over time, exposure to harsh environmental conditions can eat away at these critical conduits, compromising their structural integrity and performance.  

Here comes your savior – seamless pipe coatings, your weapon in the battle against corrosion. Let us explore how these coatings provide a robust shield, enhancing durability and extending the service life of these pipes.

Understanding corrosion: 

We must understand corrosion before continuing with the seamless tube and pipe coatings. Corrosion is an electrochemical process that occurs when metals react with their environment. It is an especially critical concern for industries that rely on pipes to transport liquids and gases. Corrosion can lead to leaks, reduce efficiency, and cause costly repairs. Harsh chemicals, moisture, and temperature fluctuations are some of the primary culprits that accelerate pipe corrosion. 

The role of seamless pipe coatings: 

Seamless pipe coatings act as a protective barrier between the material surface and the surrounding environment. You can meticulously formulate these coatings to resist corrosion by preventing contact between the metal and corrosive agents. They serve as a reliable shield, safeguarding the integrity of the pipes and ensuring their longevity. 

Types of seamless pipe coatings: 

Several types of coatings can protect stainless steel seamless pipes from corrosion: 

  • Epoxy coatings: You can choose them because of their excellent adhesion and chemical resistance. They form a durable barrier against corrosion. Epoxy coating is ideal for catering to the oil and gas industry. 
  • Polyethylene (PE) and Polypropylene (PP) coatings: These thermoplastic coatings provide exceptional resistance to moisture and environmental factors. Use them in pipelines for transporting water and chemicals. 
  • Fusion-bonded epoxy (FBE) coatings: FBE coatings offer superior adhesion and corrosion resistance. Apply them using a heat fusion process to create a seamless and highly protective layer on the pipe’s surface. 
  • Zinc coatings: Hot-dip galvanization is effective in protecting steel pipes from corrosion. They create a sacrificial layer that corrodes instead of the underlying stainless steel seamless pipes
  • Painted: Pipe suppliers recommend choosing the painted version of the pipes if users intend to use the pipes in a wet environment. For instance, if they use the pipes under soil or in the marine environment, they must choose painted weather steel seamless tubes and pipes. Painting the pipes form a protective layer over the pipes, ensuring that the actual material does come in direct contact with the wet environment.  
  • Unpainted: Users can use unpainted or raw weathering steel if they can ensure that the pipes will not be in contact with water or humidity. Even though the pipes may be outside and sometimes come in contact with rain or snow, they will not rust. Unpainted weathering steel pipes are ideal for bridges, construction projects, sculptures, etc.

Application techniques: 

There are various techniques for applying seamless pipe coatings, including: 

  • Spraying: Spray the coating onto the pipe’s surface, ensuring a uniform layer. 
  • Dipping: Immerse the pipes in a coating solution, allowing for complete coverage, exterior and interior. 
  • Extrusion: Using extrusion, apply synthetic resin on the pipe’s surface, forming a protective layer. 
  • Fusion bonding: FBE coatings form a strong bond with the seamless pipes as you apply them using a heat fusion process.  

Benefits of seamless pipe coatings: 

Why would you spend money on coatings if they did not offer benefits? Let us check out the numerous benefits of pipe coatings: 

  • Corrosion resistance: These coatings primarily protect seamless tubes and pipes from corrosion, extending their service life. 
  • Enhanced durability: Coated pipes are more resistant to wear and tear. Hence, these reduce the need for frequent maintenance and replacement. 
  • Cost savings: Since these coatings prevent corrosion-related damage, they save significant repair and replacement costs. 
  • Environmental protection: Coated pipes are less likely to leak, reducing the risk of environmental contamination. 
  • Improved performance: Corrosion-resistant pipes maintain their efficiency and performance over time, ensuring the smooth flow of liquids and gases.

Do you need to coat seamless pipes? 

Even though seamless pipe coatings offer multiple benefits, not all pipes need coatings. Applying coatings can be expensive. Many of your clients may not have the budget or requirements for using coated pipes.  

However, when catering to industries that expose the pipes to harsh environments, you must coat the pipes. Most established seamless tubes and pipes companies choose coated pipes for petrochemical, offshore drilling, shipbuilding, aerospace, and the automobile industry.  

Seamless pipe coatings safeguard critical infrastructure against the relentless forces of corrosion. In an era where durability, reliability, and environmental consciousness are paramount, these coatings play an indispensable role.
