Carbon Steel Welded Pipes / Tubes
Carbon steel welded pipes are made by rolling carbon steel plates or strips and welding them, and can be classified into longitudinal welded pipes and spiral welded pipes depending on the welding method. They offer uniform structure, stable dimensions, and relatively low cost, making them commonly used in pipelines and construction projects.
Carbon steel welded pipes are widely used in oil, natural gas, water supply and drainage, construction, machinery manufacturing, and engineering structures. They are suitable for transporting water, oil, gas, and other liquid media.
Key Advantages:
Uniform structure and stable dimensions
Cost-effective and economical
Can be cut, welded, and processed
Widely applied in oil, gas, construction, and machinery industries
