The production of seamless line pipes involves an extrusion process, where a solid round billet is heated and then pierced to create a hollow tube. This method ensures a uniform structure with no seams, greatly enhancing its performance under high pressure and temperature conditions. The billets are typically made from steel or other alloys, and the process can involve several stages, including elongation, reduction, and finishing processes such as heat treatment and surface finishing.
