The document discusses different methods for manufacturing pipes and tubes. It describes welded and seamless pipes, with welded pipes used for medium and low pressure applications like pipeline construction, while seamless pipes are used for high temperature and pressure applications like boiler pipes. Some key pipe manufacturing methods mentioned include extrusion, continuous casting, centrifugal casting, piercing, spinning, and swaging. The Mannesmann and Ehrhardt methods are highlighted as examples of piercing techniques. Tube drawing is also discussed as another manufacturing process.
