Carbon steel pipe is made by hot rolling and cold drawing. The hot-rolled seamless steel pipe is frequently used to construct the piping systems of large diameter and long distance pipelines. It can also be used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycles Frames and steel construction scaffolding. The cold-drawn seamless pipe is used for precision machinery manufacturing, pipeline transportation, instrumentation and hydraulic & pneumatic cylinders industry.
