Whether seamless, welded, ERW, or fabricated, Stellanox Steel’s carbon steel pipes deliver outstanding performance in oil & gas, construction, power plants, shipbuilding, and heavy machinery sectors worldwide.

What are Carbon Steel Pipes?

Carbon Steel Pipes are tubular sections made from carbon-rich steel alloys, engineered to deliver superior mechanical strength, toughness, and temperature resistance.

They are primarily used to transport liquids, gases, and solids under pressure and temperature variations. Based on production techniques, carbon steel pipes can be seamless (for high-pressure, high-temperature applications) or welded (for general-purpose and low-pressure applications).

Their cost-effectiveness, strength, and versatility make carbon steel pipes the backbone of modern infrastructure and industrial systems.

Frequently Asked Questions

Explore our FAQs for insights on materials, customization, and delivery.

What is the primary difference between seamless and welded carbon steel pipes?

Seamless pipes have no weld seam and are preferred for high-pressure and high-temperature applications, whereas welded pipes are generally more economical and used in lower-pressure applications.

Which grades are suitable for oil and gas pipelines?

API 5L grades such as B, X42, X52, X60, and X65 are specifically designed for oil and gas pipeline applications.

Are carbon steel pipes rust-proof?

Standard carbon steel pipes can rust when exposed to moisture; however, surface treatments like galvanizing or coatings can significantly enhance corrosion resistance.

Can carbon steel pipes be customized in terms of end finishes?

Yes. We offer Plain End (PE), Beveled End (BE), and Threaded End (TE) to match different joining requirements.
