Erw Welded Pipes
ERW (Electric Resistance Welding) pipes are manufactured by cold forming steel coils into a cylindrical shape and then welding the edges together using an electric current, resulting in a seam that runs along the length of the pipe.

ERW (Electric Resistance Welding) pipes are manufactured by cold forming steel coils into a cylindrical shape and then welding the edges together using an electric current, resulting in a seam that runs along the length of the pipe.
LSAW is an abbreviation for Longitudinal Submerged Arc Welding. LSAW pipes have a small HAZ (Heat Affected Zone) area. The production productivity of LSAW pipes is 4 m/minute, while the Weld Seam length of LSAW pipes is only 12 meters / 6 meters long.
What are the key benefits of using welded pipes in industrial applications?
Our welded pipes, including ERW, EFW, and LSAW, offer significant advantages such as high structural integrity, excellent dimensional accuracy, and cost-effectiveness. The advanced welding techniques we employ ensure robust and reliable pipes suitable for demanding environments. Specifically, they provide superior strength for high-pressure applications, excellent corrosion resistance for harsh chemical environments, and durability for long-term structural support. Additionally, our rigorous quality control processes guarantee that our welded pipes meet or exceed industry standards, ensuring consistent performance and safety.
How do I choose the right type of welded pipe (ERW, EFW, LSAW) for my specific industrial project?
Selecting the appropriate welded pipe depends on your project's specific requirements. ERW pipes are ideal for general structural and low-pressure applications due to their cost-effectiveness and good dimensional accuracy. 1 EFW pipes are suitable for moderate to high-pressure applications, offering improved strength and reliability.2 LSAW pipes are preferred for large-diameter, high-pressure applications, such as in pipelines and offshore projects.3 To determine the best option, consider factors such as pressure ratings, temperature requirements, fluid types, and size constraints. Our experienced team can provide expert guidance to help you choose the most suitable welded pipe type for optimal performance and efficiency.
What quality control measures does we implement to ensure the reliability of its welded pipes?
We prioritize quality and reliability. Our welded pipes undergo rigorous testing throughout the manufacturing process. This includes ultrasonic testing to detect internal flaws, hydrostatic testing to verify pressure resistance, and dimensional accuracy checks to ensure precise specifications. We adhere to international standards such as ASTM, ASME, and DIN, and provide comprehensive material certifications and testing reports to confirm compliance. Our commitment to quality control ensures that our welded pipes deliver consistent performance and long service life in demanding industrial environments.
