Carbon Steel Welded Pipe Specifications

Carbon Steel Welded Pipe

Carbon steel welded pipe is produced by forming carbon steel strip or plate into a cylindrical shape and welding the joint along the pipe body. Depending on the manufacturing process and application, welded pipes can provide good dimensional consistency, efficient production and competitive cost for large-volume projects.

Carbon steel welded pipes are widely used in construction, structural engineering, water transmission, mechanical manufacturing, scaffolding, industrial piping, oil and gas transportation and general engineering applications.
