Pipe Manufacturing Process for Seamless & Welded Pipe
In extrusion pipe manufacturing, a heated billet is placed inside the die. A hydraulic ram pushes the billet against the piercing mandrel, and material flows from the cylindrical cavity between the die and mandrel. This action produces the pipe from the billet. Sometimes, manufacturers produce a high-thickness pipe known as mother hollow.
