Carbon steel pipes for ordinary piping are used widely, including in piping for steam, water, oil, gas, air and more.

Applications and Features

Our carbon steel pipes for ordinary piping are manufactured using electric resistance welding and are either black or galvanized.
These pipes can be used in piping for steam under relatively low pressure, water (excluding public water supply), oil, gas, air, and more.
Grooving corrosion-resistant electric resistance welded steel pipes (Super Seams) are needed for piping where corrosion is a concern. Contact us for details.
