Seamless Carbon Steel Pipe

Seamless carbon steel pipe is manufactured without a longitudinal welded seam. It provides a continuous pipe structure and is commonly used in applications involving pressure, temperature and demanding industrial operating conditions.

Typical applications include:

• Oil and gas transportation

• Boilers

• Pressure piping

• Petrochemical systems

• Power generation

• Mechanical equipment

Welded Carbon Steel Pipe

Welded carbon steel pipe is manufactured by forming steel strip or plate into a tubular shape and welding the joint.

It offers efficient production, good dimensional accuracy and competitive cost, making it suitable for large-volume structural, construction and general industrial applications.

Typical applications include:

• Construction

• Structural engineering

• Water transportation

• Machinery

• Scaffolding

• Infrastructure

• General industrial piping
