Question:

What is the difference between seamless and ERW steel pipes?

Answer:

Seamless steel pipes are manufactured without any welding or seams, resulting in a uniform and continuous structure. On the other hand, ERW (Electric Resistance Welded) steel pipes are created by welding the edges of the steel strip or plate together to form a tube. This welding process can cause a visible seam along the length of the pipe. While seamless pipes are generally considered stronger and more reliable due to their uninterrupted structure, ERW pipes are more cost-effective and readily available.

This seam may be visible on the surface of the pipe. While seamless pipes are considered stronger and more reliable due to their uniform structure, ERW pipes are more cost-effective and commonly used for low to medium pressure applications.
