Electric Resistance Welded Pipe

Electric Resistance Welded Pipe（ERW steel pipe）

ERW Pipe is Electric Resistance Welded Pipe; it is widely used in fencing, scaffolding, engineering, etc. Our company can produce wide range of sizes which could satisfy the requirements from customers.

ERW pipes are not limited by shape alone; they come in various sizes, from thin-walled tubes for lighter applications to thick-walled ones for heavy-duty use. Additionally, they can be cut to custom lengths, offering flexibility for installation and design.

Equipment

The wall thickness of the pipe varies from 3mm to 12mm and the length of the pipe varies from 3m to 18m and in custom lengths as well. The Carbon Steel ASTM A53 Grade B Welded Pipe is welded from strips and sheets of the same grade of material. The pipes can have beveled, end, threaded end, and plain end types.

What is the Difference Between ERW pipes vs Seamless Steel?

ERW Pipe
ERW pipes are manufactured by rolling a steel strip into a cylindrical shape and welding the edges together using electric resistance. This welding creates a durable tube with a nearly invisible seam, making it suitable for a wide range of applications.

Seamless Steel Pipe
In contrast, seamless steel pipes are produced by piercing a solid steel billet and elongating it to form a tube without any welding or joints. This process results in a completely smooth surface and a structure free from weld lines, offering superior strength and reliability.

With advanced welding techniques, the gap between the two has narrowed, making ERW pipes a reliable option for many non-critical and medium-pressure applications.

Conclusion

At Rayoung we provide ERW pipes in a wide range of materials, tailored to meet the unique demands of various industries. Our advanced processes and quality control ensure that each tube meets the highest performance standards, regardless of the material.
