What Are Possible Applications of Powder Coated Pipes?

To contribute to global sustainability goals outlined in SDGs by 2030, at Daiwa Lance, we prioritize producing long-lasting products that preserve natural resources. With this purpose, Daiwa Lance has adopted powder coating as one of the cornerstone of our manufacturing practices.

This innovative approach has led to the development of Daiwa Color Pipe and Daiwa Powder Coated Pipes, whose features are strong, stiff, and corrosion resistant, widely used in the agricultural greenhouse industry to replace short-life galvanized steel pipes as well as expensive stainless steel pipes.

Beyond these applications, Daiwa Lance's powder-coated products have a wide range of additional uses. Please read the article below for more details.

 Why Do We Need Powder Coating?

Powder coating is the process of applying polyester resin powder over the surfaces of metal to enhance its ability to resist rust and beautify its appearance.

This is a very popular way to protect steel products both mechanically and visually since the 1960s. Polyester resin powder coating, if applied correctly on steel products, provides a rock-hard protective surface against corrosion, and with proper maintenance, the coating will last for a considerable period of time.

In general, polyester resin powder coating is a long-term, durable solution in comparison with traditional painting methods, as the result is more resistant to bad weather, and it is also much safer and less toxic than paint.

Introduction to Powder Coating Products | Daiwa Color Pipe and Daiwa Powder Coated Pipe

1. Daiwa Color Pipe

Daiwa Color Pipe is made from galvanized steel pipe then coated with polyester inside and outside of the pipe, which is different from painted steel that is only adhesive on the surface and likely to corrode in a short period of time.

With galvanized and polyester coating layers, Daiwa Color Pipe provides a pleasing appearance as well as long-lasting performance against harsh environments that cause metal corrosion.

2. Daiwa Powder Coated Pipe

Similarly, Daiwa Powder Coated Pipe is made from galvanized steel pipe with powder coating, but the difference lies in the fact that Daiwa Powder Coated Pipe is only coated on the outside.

The polyester coating on the outer surface helps protect the pipe from possible corrosion attack by the humidity and moisture of the surrounding environment while the inner with galvanized coated layer enables the pipe to transport air or liquid with mild corrosive agents.

3. Comparison between Daiwa Color Pipe and Daiwa Powder Coated Pipe 

Both Daiwa Color Pipe and Daiwa Powder Coated Pipe have protective powder coating layers applied on the outer surface so that it lifespan prolongs much more than the life of barely galvanized steel pipe. 

Daiwa Color Pipe offers both inner and outer polyester coatings, ensuring superior rust and corrosion protection. The production processes for Daiwa Color pipe and Daiwa Powder coated pipe are different, which leads to different production costs and ultimately different selling prices.

What are the Main Characteristics of Powder Coated Products?

1. Corrosion Resistance

As mentioned above, the most significant feature of Daiwa Color Pipe is rust and corrosion resistance to all weather conditions. The secret to this high corrosion resistance is the powder coating and independently developed manufacturing process applied to both the inner and outer surfaces. This results in our product't lifespan being extended 10 times longer than traditional galvanized steel.

As for Daiwa Powder Coated Pipe, the coating applied to the outer surface also improves the corrosion resistance ability and makes its lifespan 3 times more than conventional galvanized steel products.

2. Bendability

Bendability is a key characteristics allowing steel to be formed into various shapes.
Daiwa Color Pipe and Daiwa Powder Coated Pipe are highly bendable, thanks to the secure bond between the polyester resin coating and the steel core. This capability allows them to be shaped into various forms, including 3D bends and 90-degree angles, without cracking or peeling. As a result, our products are ideally suited for construction and pipeline applications where bending is needed.

2. Shiny Surface

By using the powder coating process, which involves curing paint powder under heat to create a polyester resin coating on the surface of steel pipes, the surfaces of Daiwa Color Pipes and Daiwa Powder Coated Pipes become very smooth and shiny, resulting in a beautiful and colorful appearance. We can apply different colors to our Daiwa Powder Coated Pipes as requested by customers for various applications.

Applications of Daiwa Powder Coated Pipes 

1. Greenhouse Construction

Humidity and harsh weather are commonly associated with greenhouses where vegetables or fruits are grown. These factors can be corrosive and shorten the lifespan of standard galvanized steel pipes, particularly the winding shafts used outdoors in the greenhouse. Daiwa Color Pipes are used in greenhouse construction as winding shafts and body frames to offer farmers a solution to the corrosion problem they frequently face, thanks to their strong durability and rust resistance.

2. Coastal Structures

Coastal areas are among the most corrosive environments, and steel structures in these areas often rust quickly due to the high concentration of chloride salt evaporated from seawater. To prevent rust on coastal structures, it is ideal to use Daiwa Color Pipes for coastal fences or handrails on vessels. These pipes extend the longevity of the structures while maintaining a pleasant appearance, thanks to their corrosion resistance and shiny finish.

3. Pipeline for Water and Liquid in Corrosive Environment 

Water supply is crucial for irrigation in agriculture. Pipelines transport water from sources to greenhouses for crop irrigation. However, these pipelines are exposed to harmful factors like sunlight, moisture, and humidity, which can shorten their lifespan if the material is not properly selected.

We recommend using a durable material like Daiwa Powder Coated Pipe for pipelines under such conditions to extend their service life. The polyester resin coating on the outer surface of the pipe helps achieve this.

Our Daiwa Powder Coated Pipe is designed with weldability to join pipe to pipe to make length of pipeline ensuring no leakage under working pressure. We continue to develop connectors that can withstand pressure and be used effectively in pipelines, and we will introduce them to you once production is complete.

4. Furniture and Racks

Housing furniture and industrial racks for factories and warehouses require not only rust resistance and attractive appearance but also pricing affordability. These furniture and racks need to be bendable and easy to assemble by joining pipes with fittings. Daiwa Color Pipe, made of mild steel with both inner and outer polyester resin coatings, or Daiwa Powder Coated Pipe, made of galvanized steel with an outer polyester resin coating, are suitable for this application.

Another advantage of using polyester resin-coated pipes for housing furniture and industrial racks is their non-conductivity, which helps prevent incidental electric shocks

 Conclusion

Powder Coatings can be applied on round, square, or rectangular pipes, depending on the customer's requirements for specific purposes. The layer of polyester resin powder coating will protect the pipes from the effects of the environment and prevent rust from forming. Furthermore, it enables color pipes and powder coated pipes to last for a long time without needing to be changed or replaced in a short period of time. Thanks to the long lasting Daiwa Color Pipe and Daiwa Powder Coated Pipe, it brings down the need of steel to use and reduces the harmful effect to the environment.
