Coating and marking are two crucial processes in the pipe industry that serve to protect and identify pipes. Coating involves applying a protective layer to the pipe surface to prevent corrosion, wear, and damage from external environmental factors.

Marking is the process of applying marks or codes to pipes to identify key specifications such as size, material type, pressure class, and other information. These marks are essential to ensure that the correct pipes are used in appropriate applications, facilitating installation, maintenance, and inspection processes, and complying with industry standards and regulations.

Some common problems often encountered in this unit and comprehensive solutions from Eonchemicals include:

1. Problem: Coat for Marking

Marking must be clear and durable, adhering strongly to the pipe. Issues such as corrosion and physical impact often make the marks or codes difficult to read, especially if the coating is too thick or incompatible with the marking ink material.

The solution to this problem is the use of proper marking techniques and high-quality marking ink materials.

Solution: EonStencil 108

This is a stencil ink for marking, specifically designed for marking pipes, casings, tubings, drilling pipes, metal drums, and other metal objects:

• Fast drying
• Excellent adhesion
• Superior resistance to solvents and environmental conditions

2. Problem: Corrosion on Coupling

Couplings, which connect two pipes, are often more susceptible to corrosion because these areas experience mechanical stress and contact with corrosive elements such as moisture, chemicals, and oxygen.

Even though pipes and couplings are coated with protective layers, friction and wear during installation and operation can damage these layers, leading to corrosion. This can result in leaks, reduced structural strength, and ultimately, system failure.

The solution to this problem is the use of more durable coatings and more meticulous application on coupling areas.

Solution: EonCoat 470 for Coupling

This product provides superior corrosion protection by forming a strong and durable protective layer on the coupling surface. The main advantage of EonCoat 470 is its ability to inhibit the oxidation process, which is the primary cause of corrosion, and its resistance to various harsh environmental conditions.

With easy and efficient application, EonCoat 470 keeps couplings rust-free, extends their service life, and reduces maintenance costs and downtime due to corrosion damage.

In addition to pipe marking, Eonchemicals also has a solution formula for high-quality road marking.

3. Problem: Corrosion White Storage on External Surface

Corrosion during storage on the external surface of pipes, often referred to as white rust or white storage corrosion, is a common issue in the pipe industry that can occur even after the coating and marking processes.

White rust forms when zinc or galvanized protective layers react with moisture, creating a brittle white corrosion layer. This issue typically occurs when pipes are stored in humid conditions or exposed to rain without adequate protection.

White rust not only damages the appearance of pipes but also reduces the effectiveness of the protective layer, increasing the risk of further corrosion on the base material. To prevent this, it is important to ensure adequate storage conditions and use appropriate and high-quality coatings.
