Seamless steel pipes are manufactured by piercing steel ingots or solid billets to form a hollow shell, which is then processed via hot rolling, cold rolling, or cold drawing.<\/p>\n<p>Seamless steel pipes are primarily categorized into hot-rolled, cold-drawn, and cold-rolled types; this article provides a detailed explanation of these three production processes.<\/p>\n<p><span style=\"color:
