MS ERW / Seamless Pipes
What are MS ERW and Seamless Pipes?
Mild Steel (MS) Pipes are essential components in construction, infrastructure, water supply, oil & gas, and industrial applications. They are manufactured in two primary types – ERW (Electric Resistance Welded) and Seamless.
Asiad Steel Industries supplies high-quality MS ERW and Seamless Pipes compliant with IS, ASTM, and API standards, ensuring durability, reliability, and versatility.
